Category 4, Topic 28 Message 6 Thu Jul 22, 1993 W.WILEY2 (Forwarded) I found an old serial printer interface that is called "Data 20" from Data Corp. in So. Cal. In it's small manual it states that it is also used for interfacing non-commodore modems up to 2400 baud. Sure enough it does co- nnect up to both the user port AND the Supra 2400. But I guess I need some help in getting it to work still. As it is, no communication passes beyond the modem with any term s/w I have tried so far. Some defaults seem to have been set up on the modems 'non-volatile' RAM: 'HS' and 'AA' (-auto answer) are lit on power-up. Any ideas? Someone suggested I use Desterm for toggling some feature.*s ------------ Category 4, Topic 28 Message 7 Thu Jul 22, 1993 CBM-MARK (Forwarded) Well, the 'HS' being on means the modem is set to communicate at 2400 baud but I'm not sure how to turn off Auto-Answer other than through the software. You might try sending the modem AT&F which should write the factory default settings to the non-volatile ram and se if that turns off Auto- Answer. Mark ------------ Category 4, Topic 28 Message 8 Thu Jul 22, 1993 CBM-ED [e.g.bell] (Forwarded) I believe if you set register S0 to 0, you will disable auto-answer. That is the register that tells the modem what ring to answer on. ------------ Category 4, Topic 28 Message 9 Thu Jul 22, 1993 CBM-MARK (Forwarded) Ed, according to my modem's manual that's right ;) I missed reading that before. Thanks! ------------ Category 4, Topic 28 Message 10 Fri Jul 23 1993 C128.JBEE (Forwarded) I think the main point of your message was that the modem is not receiving ANY commands from the computer, correct? Is so, I would like to point out generally any interface on the user port "should" be able to drive either a printer or modem. If by chance yours can not, we do have files in library #1 for building your own. ------------ Category 4, Topic 28 Message 11 Fri Jul 23, 1993 HOWIE-CBM (Forwarded) I have never heard of a "Data 20". However, if it is like any of the other dual purpose interfaces I've seen it will have either dip switches, or more likely, jumper switches internally that allow the user to switch its functions, between those of acting as a printer interface, and as one for a modem. Ostensibly, the jumpers will reverse many of the line input/output directions of various functions, affecting pins 2, 3, 4, 5, 6, 7, 8, 12, 20 and 22. Follow your manual's instructions to set these jumpers (or dip switches) to their modem settings, and any Terinal program will then be able to communicate with your modem quite nicely.

If you own an IBM PC get the files uploaded by "JBEE". I believe "null-modem" as a search or "null" will pull them all up. ------------ Category 4, Topic 28 Message 14 Thu Oct 14, 1993 D.SCHWARTZ [FORBIN ONE] at 04:22 EDT Well, I don't know what happend but I tried one of those BUILD-IT- YOURSELF modem interface projects and it didn't work. I just kept my Supra-2400's Send and Receive lights on... I checked all solder points and tested the transistors and nothing was dead... Oh well... ------------ Category 4, Topic 28 Message 15 Mon Nov 01, 1993 W.WILEY2 at 05:21 EST I ended up buying the Commodem adapter, since I can drive 30 min. from home to Software Support Int'l. It works GREAT! I just flip a switch to change from 1670 modem emulation to Hayes emulation, and all the work is done for me. I think I did need to use the Supras manual to set the defaults for its startup, but that took about 10 minutes. I thank you for the advice...it was perfect! -Will ------------ ************ Topic 29 Sun Sep 05, 1993 B.GANN1 (Forwarded) Sub: 1571 won't read at all Brenda's 1571 problems :) 8 message(s) total. ************ ------------ Category 4, Topic 29 Message 1 Sun Sep 05, 1993 B.GANN1 (Forwarded) I have a 1571 that refuses to read a disk. It just gives read errors on track 18. I had it looked at by a repair person, and he could not find anything mechanically wrong with it. He thought it might be electronic. I personally do not trust this person's abilities, though. Any ideas? Brenda ------------ Category 4, Topic 29 Message 2 Mon Sep 06, 1993 M.COLWELL1 [MattMan] (Forwarded) It wont read track 18... I'm not that fimular with repairing 1571's. If it was a 41, I'd have a chart that would list possible chips to check. Do you do reglar maintence on it? ------------ Category 4, Topic 29 Message 3 Wed Sep 08, 1993 B.GANN1 (Forwarded) No, I have done no maintenance on it :X It is rarely used. I got it used. Brenda ------------ Category 4, Topic 29 Message 4 Mon Sep 13, 1993 B.GANN1 (Forwarded) More info on 1571 that won't read... tried the pd prg multialign on it, It reports what is read from the drive and what it is trying to read. I had the drive open... I can see the head moving, but nothing is printd as being read from the drive. The program is supposed to show track and sector being read, but this area is blank. (Got 2 other 1571s to mention, but holding them off so this doesn't get too confusing :) ) Brenda ------------ Category 4, Topic 29 Message 5 Mon Sep 13, 1993 C128.JBEE (Forwarded) Where the level pushes down on the arm that holds the head, there is a piece of tape. Try putting ONE piece of thin tape on top of that. Commodore Tech Topics talks about cutting this and that spring to push the head down etc etc ... I sometimes found this a acceptable short term solution until I junked the drive. ------------ Category 4, Topic 29 Message 6 Mon Sep 13, 1993 CBM-ED [e.g.bell] (Forwarded) My 1571 started giving me extreme probems. I had problems with it several years previously, and it cost $150+ to get a new mechanism for it, so when things happened again, I feared the worst, and started asking for solutions from users on GEnie. In the end, I had to go out and buy another 1571 from a local user because we had a critical need for programs on my 5.25 disks. After I had a backup, I got bold. I disassembled the drive to see if I could see anything loose, etc. I'm not a tech, so it was pretty much just poking and pecking around inside the drive. However, I got even bolder, and totally disassembled the r/w head assembly.... removed the top head from the assembly. I got some alcohol, and with my finger, rubbed the read/write surface of both heads vigorously, then reassembled. During reassembly, I was kind of concerned that the fit was not what I considered a precision fit... it seemed there was 'slop', and alignment was a concern, but I put it all back together anyway. I reasoned that it did not work anyway, so what did I have to lose. In the end, it worked, and has worked ever since. I'm kind of more pleased with this because I have never been too comfortable with those abrasive cleaner disks anyway.... but in the end, it was the fact that I was going to have to get service or trash the drive that made me bold enough to go in and do what I did, and it did the trick. It may not be the same as the problem you are having. Mine just would not read the back side of the disk. But if the drive is not working, when you get to the point that you are ready to pay someone to fix it, or to toss it, you might want to consider this. Even now I find it hard to believe that it worked, but the drive is still chugging and that was over a year ago. ------------ Category 4, Topic 29 Message 7 Sun Oct 17, 1993 B.GANN1 (Forwarded) About the tape on the drive... I did see a little piece of tape where Jbee mentioned... But the repair person I took it too had left tape in there. I did not know that this particular piece was supposed to be there, so I pulled it out. What is it there for? Someone also told me to check a pivot arm that is supposed to move out of the way when a disk is inserted. I can't tell where this pivot arm is. What is "Commodore Tech Topics"? Brenda ------------ Category 4, Topic 29 Message 8 Sun Oct 17, 1993 C128.JBEE (Forwarded) Tech Topics are updates to the C= repair manuals. Grapevine sells them or rents them. The tape goes on the flat part of the plate under the arm that pushes that plate down to push the drive head onto the media. ------------ ************ Topic 30 Mon May 31, 1993 A.PEROTTI at 22:57 EDT Sub: Multiple cartridges in the Expansion pt How do you handle more than one cart in your expansion port? 14 message(s) total. ************ ------------ Category 4, Topic 30 Message 1 Mon May 31, 1993 A.PEROTTI at 23:00 EDT I am looking for a solution to a small problem I have with my hardware setup. I have a RAM expansion cart and a fast load cart and I am tired of swapping them in and out of the exspansion port. I understand that the Aprospand cart allows several to be connected at the same time, I remember seeing pictures in old magazines. Are these still available and are there any other options available to solve this problem? Speak to me O mighty hardware gurus! Tony Perotti ------------ Category 4, Topic 30 Message 2 Tue Jun 01, 1993 HOWIE-CBM at 10:29 EDT Tony, The Aprospand should do it. It has on/off switches for each cartridge which controls a couple (more?) lines and lets the user switch a unit in and out. It is far better, however, to begin with compatible cartridges, so that they can co-habitate in harmony in an Aprospand, without the need to switch switches. I do not believe that Aprospands are hard to find, and they should be readilly available. Certainly QBB will have them in stock. One other suggestion: With the Aprospand you may want to have a REU positioned elsewhere. To do this, expander cables fron Tenex will work nicely. Be sure to get only the cables that Tenex sells since these are the only ones that a user can shorten, if need be. Finally, you can safely disregard any warnings in the Tenex catalog that their expander cables are not for use with a REU. I have used them with two different 128's quite nicely. Howie ------------ Category 4, Topic 30 Message 3 Tue Jun 01, 1993 A.PEROTTI at 21:47 EDT Thanks for the response, Howie. I presume QBB=Quick Brown Box? Do you have their phone #? I posted a similar message on a local BBS and the reviews of the Aprospand are rather mixed. Some other choices have been recommended, specifically the Skyles 2+1 or 4+1 and the Cardco Cardboard expanders were mentioned. Do you have any info/opinions about these? Tony ------------ Category 4, Topic 30 Message 4 Wed Jun 02, 1993 HOWIE-CBM at 09:43 EDT Tony, Yes! I was referring to the Quick Brown Box folks. Their specifics: Brown Boxes, Inc. 26 Concord Road Bedford, MA 01730 Tel: (617) 275-0090 (617) 862-3675 I know of the other interfaces you mention, but never used them. Sorry, cannot be any more help on that. Howie ------------ Category 4, Topic 30 Message 5 Sun Jun 06, 1993 A.PEROTTI at 11:58 EDT Thanks Howie! Does anyone else out there have any experience with those interfaces? This is the best part about being a C= user and being on GEnie, there is always someone to lend a hand!!!! ------------ Category 4, Topic 30 Message 6 Sun Jun 06, 1993 GULLIBLE [Jon] at 16:58 EDT I've been using the Skyles 2+1 with Super Snapshot and a 1750 Clone for at least two years and have never had any problems. The Skyles 2+1 is good in that it lets you put the REU in the back slot laying flat so you don't have to balance it. ------------ Category 4, Topic 30 Message 7 Wed Jun 09, 1993 HOWIE-CBM at 15:24 EDT Jon, That's why the Tenex ribbon cables are nice. Let's you place a REU pretty much anywhere. Howie ------------ Category 4, Topic 30 Message 8 Sat Jun 12, 1993 T.ALLEN [Dynamite] at 20:35 EDT The Skyles IEEE interface and there are some others that I have been hearing about. CMD has the information about it. They tell you that you will definately have to use this if you wish to use the normal REU along with the Swiftlink Cartridge at the same time. Skyles Phone Number is 1-408-737-1632 and they are located at: Skyles P.O. Box 1984 Cupertino, CA 95015-1984 What you need is the Skyles 2+1 and it is $34.95 + $3.50 shipping and handling. Have a great one!! ------------ Category 4, Topic 30 Message 9 Sat Jul 03, 1993 F.OGLE [Color 64 BBS] at 15:38 EDT Howie, those ribbon cables are notorious for causing slight timing problems tho. CMD sells the 2+1 I believe, too ... Hey, if it makes the LtK-HD work with swiftlink, it'll fill your needs quite well :) ------------ Category 4, Topic 30 Message 10 Wed Sep 08, 1993 G.CORREA [RAMRunner] at 21:43 EDT I have an older CardCo 5-slot expander and love it. I like the fact that, with compatible cartridges, I can have any number of cartridges on-line at the same time. Question: Due to the aquisition of a Supra 9600bps modem, I would like to snag a SwiftLink cartridge. Does anyone know if they're compatible with a 1750 REU, via the CardCo...? Thanks! ------------ Category 4, Topic 30 Message 11 Wed Sep 08, 1993 M.COLWELL1 [MattMan] at 22:41 EDT I believe the Swiftlink plugs in through the User Port, not the Cartrage Port. So there should be no problem. I'm looking for a cartrige port expander myself. One that is compatible with the Snapshot, and a 1750 REU. I can't find anyone who is selling the Aprospand board anymore... Any Suggestions? MattMan ------------ Category 4, Topic 30 Message 12 Thu Sep 09, 1993 C128.JBEE at 01:35 EDT As noted in Cat#12, with Rose, and with Howie's recent posts, using a REU and Swiftlink at the same time is not an easy or desirable action. The S/L plugs into the expansion port on the right hand side. ------------ Category 4, Topic 30 Message 13 Thu Sep 09, 1993 CMD-DOUG at 13:16 EDT The Skyles 2+1 is a good alternative. Available from CMD. ------------ Category 4, Topic 30 Message 14 Mon Sep 20, 1993 P.KELLER5 [Diesel II] at 04:38 EDT You might try Software Support International (1-800-356-1179) and find out if they have the adapter for your modem. I saw a couple, but didn't check to see if they are compatible with your modem. ------------ ************ Topic 31 Sun Sep 05, 1993 E.TOLBERT (Forwarded) Sub: Fan Installation on a C128D I have a 12VDC 100mA fan I want to install in my C128D.

Recently, I purchased a 1702 COlor Monitor, 1541 disk drive, and Commodore 64 computer. Prior to my purchase of this hardware, the problem did not exist. The problem being the 1541 that I run my BBS with will not load the MAIN BBS program back into memory. The MAIN BBS program is on drive 8 and drive 8 is a 1541. I also use a 1541II where the modules or external programs are kept and also a C128D. When I purchased the hardware, I sat the regular C64 on top of my Commodore 128D. I use the Commodore 64, 1541(not the one used to run the BBS), and the 1702 Monitor for my personal use. The 1702 and 1541(personal use) is sitting on top of my color televison that I use for the BBS. Do I have to use something to seperate the equipment to prevent interference? The reason I'm asking is sometimes the BBS will attempt to load the MAIN PROGRAM back into memory and my 1541 just SPINS.. There's no error messages.. The problem don't occur when I log on in local mode. They happen periodically. Why? Any suggestions? ------------ Category 4, Topic 32 Message 2 Sun Sep 05, 1993 C128.JBEE at 23:37 EDT Disk drives will be directly effected if they are kept too close to monitors or TVs. Also, the old C-64s and flat C-128s produce a large amount of EMI, I imagine having your C-64 on top of your C-128D is not doing either very much good. ------------ Category 4, Topic 32 Message 3 Mon Sep 06, 1993 M.COLWELL1 [MattMan] at 14:47 EDT Have you cleaned the drives heads?

It would give a lot of errors, as if I was pressing keys before pressing RETURN (I.e. after pressing return it would print a whole line of garbage and say it was in invalid response.) Anyway, I unplugged the modem for about 6 weeks, then today desided to try it again. It works without any problems so far. Is something wrong with my modem, computer, phoneline, or what? Bob. ------------ Category 4, Topic 33 Message 2 Sat Nov 20, 1993 CBM-ED [e.g.bell] at 07:32 EST Bob: BK> as if I was pressing keys before pressing RETURN (I.e. after BK> pressing return it would print a whole line of garbage and say BK> it was in invalid response This sounds a lot like a noisy phone line. Maybe your phone company upgraded their equipment in the 6 week interim. Another thing that might have caused that, tho I doubt it would be at 1200 baud, would be inability of the modem to handle the baud rate. One sign of a modem going bad is when it starts sending a lot of UUUUUUUUUUUUUUU characters as I recall. ------------ Category 4, Topic 33 Message 3 Sun Nov 21, 1993 B.KIRKLAND at 06:58 EST I forgot to mention: This also did not work: OPEN 1,2:PRINT#1,"ATDT" That should have made the dial tone sound in the speaker in the modem, but nothing happend. Like I said tho, everything works fine, for now.

The 1670 may not handle that without a delay between each of the characters. It has been a long time since I did any BASIC programming to send characters to the modem, but I kind of remember that the 1670 did require a delay after each character sent to the modem. ------------ Category 4, Topic 33 Message 5 Mon Nov 22, 1993 M.RANDALL2 [Maurice] at 00:27 EST If this helps any, here is the basic loader I use when logging onto Q-Link. This first disables the speaker in the modem and then proceeds to load and run the QLink software. (I disable the speaker so that my wife can't tell when I'm running up the credit card bill) 10 open5,2,2,chr$(0)+chr$(0)+chr$(61)+chr$(1):forl=1to500:next 20 ms$="atm0":print#5,ms$+chr$(13) 30 for l=1to500:next:close5 40 %quantum Notice the delay after opening the channel to the modem, and then the next delay after sending the command to turn the speaker off. And then line 40 loads up QLink. I have JiffyDos, so the '%' works in my case to load 'quantum'. Where I placed the 'atm0', you could substitute the 'atdt' to initiate the dial tone. ------------ ************ Topic 34 Tue Dec 07, 1993 F.WILSON4 at 20:42 EST Sub: 128 D PWR Supply and Fan Question I have a 128 D with 3 drives, two printers, and a 1750 REU.

I've got my fan pushing air out, not in. Secondly, when I opened up my 128-D to install my RamLink (that's when I got the fan idea), you should have seen the dust that was in there from all those years! I suppose a lot of dust would have to be introduced before anything could possibly be screwed up in any way.

Now that I have had a good amount of experience in ML programming on the C-64, I opened it up and started playing around with it again. I never knew that the C-64's Joystick Ports could be used for OUTPUT!! I remained skeptical as a hooked up the simple sample circuit and freaked out when I ran the driver code and the LEDs flashed!! One example read Port 1 and ran the lights off Port 2. Another one just flashed the LEDs. According to the text, 5V mini- relays can be substituted for the LEDs to control motors, lights, or anything else you can think of! I never knew it was that simple to control external devices with my C-64! I always thought that you needed a complex interface and evn more complex code to run it! In the simplest circuit, you can hook four LEDs directly to the I/O lines on the port and it works fine!! Has anyone else played with this idea of external control? I know that Atari 400 and 800 computers had several devices designed for them that were completely controlled by their Joystick Ports. In fact, I have an Eprom programmer for an Atari 800 that uses all 4 joystick ports to communicate with the computer!! ------------ Category 4, Topic 36 Message 2 Thu Dec 09, 1993 C128.JBEE at 23:56 EST There are places using C-64s to control complicated lathes and some using computer vision to check the process assembly. :) ------------ Category 4, Topic 36 Message 3 Fri Dec 10, 1993 S.GOLDSMITH2 [Iron.Man] at 04:36 EST The Covox Voice Master uses the joy port for high speed I/O too. I was able to read and write at about 22K baud without any kind of CRC checking. The joy and cassette ports have a lot of posibilities for high speed I/O and are often overlooked... SG :) ------------ Category 4, Topic 36 Message 4 Mon Dec 13, 1993 D.SCHWARTZ at 03:34 EST Do you know of any hardware hacker books that deal with the subject of high- speed I/O by way of joystick or cassette ports? For a few years in Arizona the phone company zoned different areas so that it would cost long distance to call across cities. One rebel SysOp built an interface using the cassette and joystick port of a VIC-20 to act as a controller for his C-64 based BBS. The system (called Switchbaud) allowed a caller to choose a BBS from a list and then connect the caller across his second line so that the long-distance charges were defeated if calling across cities. nce the phone-company did away with the charges, his board disappeared. I wish I could have asked him how his interface worked! Just out of curiosity, do you think it would be possible to control an IBM- style hard-drive controller through the cassette or joystick ports? That project in the download base for the C-64 hard drive interface wedges the controller into cartridge memory, but that will take a long time to write an operating system that is both memory-conservative and operational! This may be a little crazy, but do you think it may be possible to use one C- 64 as a hard-drive controller for that project and then connect it to a second C-64 which can use the first C-64 as a serial-device to control the hard drive? I have a few extra C-64s laying around that I could butcher. I wonder if I could write a program that will mimic the floppy serial bus on the C-64. Then I could just jam the C-64's motherboard into an XT case with the hard drive and have the hard-drive DOS in the C-64 with an EPROM. Looks like I'm kind-of getting off the subject, but one last thing: I have an EPROM programmer for my Atari 800, but I think the Atari is a pain in the butt to use. Do you know where I can get one for the C-64 or 128? Thanks- Derek ------------ Category 4, Topic 36 Message 5 Tue Dec 14, 1993 S.CLEMENTS [Krazy Kat] at 03:09 EST I've read a couple of posts on a local C= board about an EPROM burner for the C64. It may have also been on the Pearako Net as well. - Krazy ------------ Category 4, Topic 36 Message 6 Tue Dec 14, 1993 S.GOLDSMITH2 [Iron.Man] at 05:14 EST DS, I haven't any articles on high speed joy stick I/O. I was able to figure out how by using a monitor to look at what Covox did in their Voice Master software. If you have a book like Mapping The 64 it will give you detailed CIA programming info. The have the first Mapping the 64 which had a few errors in the CIA section, but I was able to figure it out...

Well, I would love to have and Eprom programmer for the C-64, so if you find out anything can you let me know? ------------ Category 4, Topic 36 Message 8 Thu Dec 16, 1993 S.CLEMENTS [Krazy Kat] at 01:08 EST I certainly will. - Krazy Kat ------------ Category 4, Topic 36 Message 9 Sun Dec 9, 1993 L.SCHONDER [Lou] at 23:35 EST Jason-Reiheim stills sells EPROM programmers.

If it is off topic, I'm sure someone will let me know...... I recently aquired a Panasonic 1124 printer and need the instruction manual and the front flip door for it. Could someone please post the address + phone number of the nearest Panasonic service center to the state of Louisiana so I can order these two items? Thanks in advance..... ------------ Category 4, Topic 37 Message 2 Sat Dec 18, 1993 CBM-MARK at 09:10 EST Panasonic's technical support number is: 1-800-222-0584 They should be able to give you the info you need. The phone number is from the manual of my 1091 so there *is* a chance it may have changed in the last few years. Worth a try though ;) Mark ------------ Category 4, Topic 37 Message 3 Tue Dec 21, 1993 R.PATERNOST2 [Ray] at 01:04 EST What a coincidence; the same number is in the manual to my 1091 printer as well :-) (I was calling the various service center numbers on the green insert.) ------------ ************ Topic 38 Sun Dec 19, 1993 D.BOBER [RENTaLASER] at 00:18 EST Sub: VDC Interlace Mode Question about the Interlace Modes on the VDC and older C-128's @s 1 message(s) total ************ ************ Topic 39 Fri Dec 24, 1993 F.WILSON4 at 21:48 EST Sub: I need help with A Star SG-10C If anyone know anything about the Star SG-10C or the SL-10C please let me know. 0 message(s) total ************ ************ Topic 40 Wed Dec 29, 1993 T.SAUVE [Hari Seldon] at 02:09 EST Sub: My C-64 'resets' itself.

I can then type any leagal command and it works... for awhile. then it does it all over again. i thought it was my power supply, but i borrowed one from a friend who aassured me that it was a good power supply and i still have this problem. does anybody have any suggestions on how i can figure out what the problem is? i like my commie but if it needs major surgery, i may just have to bury it and go buy a beamer. any help would be appreciated. tthanks, todd ------------ Category 4, Topic 40 Message 2 Wed Dec 29, 1993 C128.JBEE at 10:31 EST If you have an older C-64 (brown case) the mostly likely culprit is the PLA chip. ------------ Category 4, Topic 40 Message 3 Thu Dec 30, 1993 T.SAUVE [Hari Seldon] at 01:48 EST yeah, its an older commie 64. the motherboard says its copywrited 1983 and the artwork for the board says it's rev 'b'. is it worth the hassle of getting a
