From the command panel press the 'power online' switch then you can select your desired print pitch and then your NLQ Type Style. This is one way to select at least the italics. To do the Bold, underline etc., there are some basic program routines in the manual. I'll post them if you'd like, but almost any word processor can do that within it own program. For a manual you could also call Star Micronics for a manual for about $12 I think. 800-227-8274 Hope this has been of some help :> ------------ Category 4, Topic 2 Message 3 Fri Jun 24, 1994 A.PLATT3 at 22:39 EDT Thanks for the Star 800 number!

(XT/AT, not PS/2) I don't know whether it will work on a 128 or not, but I do know it'll work on the 128 in 64 mode. Arthur Platt ------------ Category 4, Topic 3 Message 5 Tue Jun 28, 1994 J.STEPHENSO1 [Jimbo] at 01:41 EDT A.PLATT3, if you are talking about the file I think you're talking about, there is now a hitch. As I recall, the interface that you built from the instructions in that file requires the use of a digital switch, from Dallas Semiconductor. There was a message in the usenet newsgroup COMP.SYS.CBM a few weeks back about it that said that Dallas took that chip off the market because it was flakey. No mention was made about possible replacements. If anyone knows of a second source for a digital switch, it would be greatly appreciated (my Jameco catalog isn't the most user friendly, and my TTL databook is circa 1986, so no help there either). Jimbo ------------ Category 4, Topic 3 Message 6 Wed Jun 29, 1994 D.TUOMI [Doctor] at 00:43 EDT Also, I think this little plan is only for 64's. The 128's keyboard has a different pin setup.

Jason ------------ Category 4, Topic 3 Message 10 Wed Jul 27, 1994 CBM-ED [e.g.bell] at 03:19 EDT I've wondered about that Ravenloff. I suspect they would... the internal parts that is. I don't have a 128D and have never actually gotten very close to one, but it just seems logical to me. I saw the ad in Commodore World. Anyone here w/a 128D know if you can cannibalize keyboard *parts* for use on a flat 128. I'm talking about the key caps, the contacts, perhaps even the pc board? ------------ Category 4, Topic 3 Message 11 Wed Jul 27, 1994 H.HERMAN1 at 05:31 EDT Ed, I am not sure about parts interchangeability. I do know, however, that some users have connected a 128D keyboard to a flat 128. One thing to watch for is the keycaps. Only the early 128D keycaps match the flat 128's. Later 128D's have the graphic (shifted) info on the keycap top, along with the key letter. (On the flat 128, shifted graphic symbols appear on the front side of the keycap.) This took a day or two to get used to when I swapped a flat 128 for a 128 of the D variety. Howie ------------ Category 4, Topic 3 Message 12 Wed Jul 27, 1994 C128.JBEE at 09:48 EDT I have a couple of C-128Ds and I prefer the one with the graphics on the side of the keycap.

I have a 1351 mouse. It doesn't work. Well, at least it doesn't work right. It will move the cursor up and down, but won't move it side to side. I am using this mouse on a flat 128. I know the mouse itself is good, since I have checked it out on my 64 with no problems. I thought maybe it was a bad CIA chip (6526), so I swapped it with another one I had lying around. I also re-soldered the bottom legs of CIA socket in case there was a loose connection. BUT IT STILL DOESN'T WORK! Any helpful hints would be appreciatd. Bob. ------------ Category 4, Topic 6 Message 2 Mon Mar 28, 1994 CMD-DOUG (Forwarded) Mouse input is handled by the SID chip, not a 6526 CIA.

Bob ------------ Category 4, Topic 6 Message 5 Tue Mar 29, 1994 B.MASSE (Forwarded) Well, it's now twelve hours later and I have swapped 3 separate SID IC'S to the 128. The mouse still only will work in the vertical direction and not in any other direction... What might I check or swap next to trouble shoot the little booger? A little history on the mouse problem... originally it worked for about five minutes and then it would switch out... I guess after something heated up or something... got me. I will be listening to any helpful (or even non-helpful) advice on my problem... I sure love this machine. Bob ------------ Category 4, Topic 6 Message 6 Wed Mar 30, 1994 C128.JBEE (Forwarded) Make sure the pins on the C-128 side are clean and straight, then look at the mouse and make sure the sleeves for the pins are straight inside the connector. BTW: do not rub the 128 connectors (static). Just look for something simple like a piece of paper or plastic "popcorn" stuck amoung the pins. ------------ Category 4, Topic 6 Message 7 Thu May 26, 1994 T.FARRELL5 [12Paws] (Forwarded) My mouse (1351) just started to do the same thing. It only works in the verticle direction. I tried a different 1351 which worked O.K. The ball and rollers are clean. How does this mouse work? What do the black plasitc "wheels" with the evenly spoced wholes do? How does it "Sense"? Any help would be appreciated. ------------ Category 4, Topic 6 Message 8 Thu May 26, 1994 CMD-DOUG (Forwarded) On either side of the 'wheels', as you put it, are optical transmitters and receivers. The spokes 'break' the light path, and this information is fed to chip inside the mouse to be decoded as movement. There could be any number of things wrong... bad transmitter or receiver, chip could be bad, or you may be having a problem with the SID chip in your computer; there is also an analog switch chip in your computer that the mouse input lines run through, and this could be going bad. Also remotely possible that one of your CIA chip could be going bad, since it controls which port input gets fed through the analog switch; this latter would probably also show up as a keyboard problem as well, though. Try testing the mouse on another computer, if possible. If it does work on another machine, the problem is in your computer. At that point, try to locate a program that uses the mouse in the alternate joystick port. If it works there, then the SID is okay; if not, then you're still faced with the possibility of any of the three chips I mentioned being bad. If the mouse doesn't work on another computer, then your chances of fixing it are pretty slim, since the parts are not of the 'off-the-shelf' variety. ------------ Category 4, Topic 6 Message 9 Fri May 27, 1994 R.DAY (Forwarded) The transmitter and or recevier LED's probabiliy is why your mouse don't work in one direction. I fixed about 5 mouses and that is all that was wrong. I got the other LED's for a 1350 mouse, a joy stick mouse. I don't know were you can get the LED's. If some one has a nother 1351 thata don't work I am sure one of the 8 LED's will be good. The CMD mouse only has 4. One LED has 3 lines to it. So in must be 2 bilt in to one LED. Just unsolder them and put good ones in. If you can find good ones. I am sure this is whats wrong. You can even use the LED's out of a Amiga mouse. ------------ Category 4, Topic 6 Message 10 Fri May 27, 1994 B.MASSE [BIG BOB] (Forwarded) CMD-DOUG at 23:32 EDT > since it controls which port input gets fed through the analog >switch; this latter would probably also show up as a keyboard problem as well, >though. Good info Doug. Now, what is the number of that analog chip in the 128 and is it compatible with the chip that is found in a 64. U28 on the 64 , chip #4066, according to my 64 schematic looks likes it may be the analog chip. I would really like to get my mouse working on this old 128. Also, I recently downloaded a file that showed the logic probe findings for chips on the 64. Is there a file on GEnie that shows those reading for the 128. Bob Masse' .... Keyboard not found ... THINK F1 to continue ------------ Category 4, Topic 6 Message 11 Fri May 27, 1994 CMD-DOUG (Forwarded) According to the 128 schematic, a 4066 was employed there as well. ------------ Category 4, Topic 6 Message 12 Sat May 28, 1994 S.EYRSE [steve] (Forwarded) Probs with the vertical mouse moves on the 1351.. I'm starting to get this also!!! have had it for a long time..But perhaps these mice are starting to die.. Doug Trackball.. how to order please..That will be my next move. Also will the trackball have a "clock" in it like the mouse ? ------------ Category 4, Topic 6 Message 13 Sat May 28, 1994 R.DAY (Forwarded) There are 2 4066 chips in your commodore 128/64. They are just a chip with 4 switchs in them. Put 5 volts on one pin and two other pins will connect. One is used for the color RAM to switch 4 address lines. the other is used to switch the 2 SID chip POTX and POTY for the up down, or left right moveing of a mouse or paddol. So the other 4066 connect port one or two to the POTX and POTY of the SID chip. A CIA will tern on of off the connections. If you have two paddols that put in to one joy stick port you could test it the 4066 is getting the connections to the SID chip. I seen at left 5 commodore mouses and if they did not move up or down, left or right it was just the sensors, like the LED's in the mouse's. I bet this is a lot of peoples problums with there mouses. I used up all the good LED's in my 1350 mouse to fix all the ones I did. ------------ Category 4, Topic 6 Message 14 Sat May 28, 1994 CMD-DOUG (Forwarded) RE: Ordering the CMD Trackball... You can place an advance order by calling our Order Desk (800-6383-CMD). It is still a few weeks from being ready to ship, but you won't get billed until yours is ready.

Sounds like that to me anyway. What other symtoms might one get with a half-way blown 4066... Bob Masse ------------ Category 4, Topic 6 Message 16 Sun May 29, 1994 MIKE.DUNCAN [Scratch] (Forwarded) Big Bob, ======= WARNING ======= Long Post w/ ASCII Art! ======================= The 4066 in my C-128 is a M4066, made by OKI. Designated as U2, it's called a Quad Bilateral Switch IC (4 on-off switches). Each switch section has two I/O lines, which are connected by an off-on control (Ctl) line. (See below) Apply a HI (1) [+5v] to close, and a LO (0) [0v] to open. They're easy to check with a logic probe, DMM, or o'scope. The 4066 IC is a 14-pin CMOS DIP, layed-out something like this: ================= I I (CN3-9) I .-----[C]-.

The other sections function identically. With the computer idling, and no peripherals connected, the pins of U2 should read as follows: Pin Probe Pin Probe --- ----- --- ----- 1 Off 8 Pulse 2 Pulse 9 Pulse 3 Pulse 10 Pulse 4 Off 11 Pulse 5 Low 12 Pulse 6 Pulse 13 Low 7 Low 14 High Hope this helps. ------------ Category 4, Topic 6 Message 17 Sun May 29, 1994 B.MASSE [BIG BOB] (Forwarded) Scratch...

Then use the C-64 as a printer buffer attached to the C-1526. Basically you set the PC to use a LPT1 at 1200 baud, run a terminal program on the C-64 that acts like a buffer, and attach the C-1526 to the C-64. There was an article in an old Commodore Computer magazine with the needed directions and software. Maybe someone can cough up the issue for you.

Thank you in advance, ------------ Category 4, Topic 23 Message 2 Thu Apr 28, 1994 L.MCCLURE (Forwarded) In message #37, dated 4-13-94, J.LABAUVE [Ravenloff] said: "I bought a used 64 a few years ago and along with it came a funny looking thing called a Magic Voice." It plugs into the cartridge expansion port on the C-128. It should have an RCA jack for audio out. You can either run a cable from this directly into the aux input on an amplifier or the audio input on you monitor. Originally, this came with a cable that coupled it into the "audio in" line on the C64's monitor port, which feeds thru the SID chip. This allowed the sound to also be routed thru the RF modulator, so TV users would have speech come out the speaker there, as sounds from the SID chip do. As to how to use it, I am uncertain. If it had an onboard ROM, it might patch in a new command or set of commands. I suggest after plugging it in you try something like: SAY "HELLO" If that fails (giving a syntax error) chances are it uses the standard BASIC 2.0 commands for opening a channel and sending commands or data to it. However, finding the device number (and possibly the proper secondary channel) could be tricky if this is the case. Hopefully, someone else with a Magic Voice module, or at least the manual, will step forward and offer you more help. BTW, the cart port opening on the top of the Magic Voice (beneath the hinged door[s]), is a cart port pass-thru. Most devices that use the cart port can be plugged into the Magic Voice there and work in conjunction with it (providing their address does not conflict with the MV). If you happen to decide to sell it cheap, keep me in mind. P.S. - That should have read "cartridge expansion port of the *C64 or* C-128 up at the top. I expect it may only work in 64 mode on a 128, however. ------------ Category 4, Topic 23 Message 3 Sun Jul 24, 1994 C128.JBEE at 19:22 EDT Since U113 is close to the cassette port and #1 is on the outside edge of the IC you can easily run a switch out through the cassette port too.

The 1581 uses +5V and +12V (the standards in the computer industry), and I've seen many open frame power supplies for really cheap prices (<$20) from a number of electronics vendors. From there, you'd need a case to put it in, and you'd have to use the drive-side power cord from the dead power supply, as the connector appears to be a proprietary one. An older <150 watt PC power supply is also fine for this purpose. ------------ Category 4, Topic 25 Message 3 Fri Oct 14, 1994 C128.JBEE at 23:58 EDT I think CMD still uses or sells C-1581 power supplies. ------------ ************ Topic 26 Sun Sep 18, 1994 W.MAALOULI [vorticon] at 23:43 EDT Sub: device # switch on internal 1571 drive Hi! Iof the 128D, making it a cinch to switch device numbers. This is great, and I want to know how to do this. Thanks for your help! 2 message(s) total. ************ ------------ Category 4, Topic 26 Message 1 Sun Sep 25, 1994 S.EYRSE [steve] at 16:22 EDT Putting switches in the 128D is as "easy" as it is with the 1451 or 71 self standing drive. On the main board on the left (looking towards the front) edge of the Drive you will see the "normal" (I-I) half pads. These are a circle that is cut into with a small strip of printed circuit joining them. You need to attach the leads to two switches to each side of the pads. You can use three wires as the left side of the pads are joined together. I mounted my small Radio Shack switches in the plastic front of the 128D just to the right of the name plate. You need to CUT the small trace that joins the pads to put the switches online. Look under other drive topics the 1451 information for more on this to help you know what the pads look like. If both switches are open your in drive 11. If both are closed drive 8. either one open with other closed you'll have 9 or 10. I have found this to be a great help with Geos as I use a 1581 boot disk and need the 1571 built in to be drive 11 for TopDesk. OR if you don't want to open up your computer and go poking around get the file for disk swapping that I uploaded here. It will let you change the numbers of any two drives online it is in basic for the 64 but works just fine on the 128 you could make it a auto load to put you in that mode when ever you turned the 128 on. Hope this helps ..Steve :) ------------ Category 4, Topic 26 Message 2 Sun Sep 25, 1994 W.MAALOULI [vorticon] at 18:31 EDT Thanks Steve! I will definitely try the procedure you described. I seems pretty harmless. I'll let you know if I run into any problems. By the way, while we're on the topic of the 1571, do you know where I could find the 1571 drive controller chips 2114 and 2016? I'm having trouble writing to my drive (data gets corrupted), and somebody suggested that the trouble probably was related to one of those chips. In view of their low cost, I guess it wouldn't harm to replace them. (I tried cleaning the drive heads, to no avail). ------------ 4 | ************ Topic 35 Tue Nov 08, 1994 A.PLATT3 [Arthur] at 23:09 EST Sub: Installing 128D 2nd SID Discussion on the differences between the installation of the 2nd SID on the 64, 6and the 128D. 1 message(s) total. ************ ------------ Category 4, Topic 35 Message 1 Tue Nov 08, 1994 A.PLATT3 [Arthur] at 23:11 EST What are the differences in the installation of the second SID in the 128D than, let's say the flat 128?

Thank you. 5 message(s) total. ************ ------------ Category 4, Topic 39 Message 1 Fri Nov 25, 1994 K.UHLMAN [PaperTyger] (Forwarded) The knob on my 1541 II disk drive broke off. I can't use the drive because I can't close the door over the disk to hold the disk in place. I tried repairing it with tape but the knob is cracked and it won't hold and won't work the door. Can anyone tell me where I can buy just a new knob (handle)? If you know, please send email to K.UHLMAN. Thank you very much. :) By the way, I have a C64. ------------ Category 4, Topic 39 Message 2 Sat Nov 26, 1994 CMD-DOUG (Forwarded) Might be hard to find such a part unless you can get it from someone who has a junked drive that they are parting out. But as long as you still have the cracked part, why not repair the crack with superglue? As long as you let it set sufficiently long, repairing that way should hold. Tape, on the other hand, gives as it is stressed, which is why that generally won't work for this kind of a fix. ------------ Category 4, Topic 39 Message 3 Mon Nov 28, 1994 K.UHLMAN [PaperTyger] at 03:50 EST Thank you very much for your suggestion. I have tried to glue it with Duco cement but the knob is cracked in several places and in fact, a piece of it is coming off so I don't know if gluing will work. When I tried before I just got a mess. But I'll try again. Meanwhile, if anyone else has one, please let me know! Thanks again. Kitty ------------ Category 4, Topic 39 Message 4 Tue Nov 29, 1994 H.STEVENS5 [HaroldOH] at 20:56 EST PaperTyger here is one solution that I have used on my crack 1541-II knob. I took epoxy and placed in the cracks and then taped it all together. After the poxy dried I removed the tape and carefully slid it back on to the disk drive. Another solution would be to use a pair of needle nose pliers (while you are waiting for the epoxy to dry) or if you can find an old radio or television volume control knob with a "D" shaped hole try and see if it will fit. --Harold ------------ Category 4, Topic 39 Message 5 Tue Dec 20, 1994 C128.JBEE at 03:59 EST > K.UHLMAN [PaperTyger] > Can anyone tell me where I can buy just a new knob (handle)?
