Features are as follows: -Definable scroll area (2-25 lines) -Complete <TAB> facility - The tab stops can be individually set and cleared or set at fixed intervals. The back-tab function returns to previous stop. -Clock/Calendar - Time and date reported in ASCII and cycling automatically. -Alternate character set capability - Supports character generator ROMS containing 256 characters. The extra 128 chars. can be simultaneously displayed with the standard set. -Transparent mode - Each of the possible 256 codes displayed as a unique character. -Hardware (CTS:RTS) handshake or standard <XON>:<XOFF> handshake -Slow transmit mode - characters spaced apart to prevent overrun at high baud rates -Light pen support -VT-100 emualtion -Reliable operation at 38K baud. There are a few more features the sales blurb describes as well. This sure sounds like a winner to me, but bear in mind I have not seen these ROMS in action and this is therefore not a recommendation! I hope to get hold of a set in the next few weeks and will report at that time. The price for the firmware is $50 and is available from: Extended Tecnology Systems 1121 Briarwood Bensalem, Pa. 19020 Regards, Charlie Strom <CSTROM @ MC> 7-Aug-82 18:35:44,509;000000000001 Mail-from: ARPANET site MIT-MC rcvd at 7-Aug-82 1834-EDT Date: 7 August 1982 18:28-EDT (Saturday) Sender: CARTER at RU-GREEN From: Robert A.

See my previous message to H19-People for preliminary details. My spies at the recent HUG convention in Chicago assure me that this is indeed a real product and looks like it is well worth the cost. There was considerable interest in my forst message, so I will be sure to report as soon as I have the beastie. I have also obtained a file containing all the escape codes (original and enhanced) and will upload the file to MC when I can report some concrete information. Extended Technology Systems is obviously a garage operation (George Deffendall is the person in the garage!) but nontheless I am very optimistic that the enhanced H19 will be a terrific package.

For those who missed my first message, this is a replacement 32K rom available from Extended Technology Systems, 1121 Briarwood, Bensalem, Pa. 19020 for $49.95 post- paid. The phone is 215-754-4604. There were several queries re the VT-100 emulation mode. I am not a DEC afficianado, so I can only report that the documantation states that EDT operation is greatly enhanced compared to the old VT52 mode using the VT-100 mode. All features are implemented except for slow scroll and character size change. I have also used the clock/calendar without a hitch (note - no battery backup, though one might add it), the slow transmit mode at high baud rates (characters spaced apart to prevent overrun at other end), transparent mode, etc. Feel free to query me re specific areas I have not covered.

The shifted function keys are a nice touch and enable me to run a version of Wordstar using the numeric keypad (in shifted mode) and the function keys to perform most of the operations. I am using the 25th line for labels for the function keys but may use the 24th as well (the rom allows as many lines as you want to be inaccessible a is the 25th under normal conditions.) I also use like the option of changing the cursor to a solid underline, a slow blink, etc., depending on my mood or the phase of the moon. The slow transmit feature (characters are spaced out so as to prevent UART overrun on the other side) is another useful touch. I have not noted any bugs though I have benn told by a Heath expert that there are some minor (unspecified ones). I do seem to lose synch every now and then for a few 10's of ms. it seems, but I do not know if this is related to the super-19 or not. I also had to give up running at 19.2K baud; the terminal will overrun its buffer under certain conditions and it got too annoying. I understand if I were to modify the h19 to run @ 3Mhz, it would cure things, but I haven't a clue as to how to do this since my machine is a late version sans jumper areas for this purpose.

From: bridger at RAND-UNIX Thanks for your report. What are the possibilities for adding an alternate-page memory buffer to the h19 that could be combined with the transmit-page feature? Jeffrey Stone recently pointed out the utility of using this as a local notepad that can then be printed or filed if desired? I find 19.2Kbaud a real plus when using a full-screen editor or simply TYPEing a text file. With the 3MHz jumper modification I get good results. Is anyone running the super19 rom in this configuration? However, I am getting snafus with an interrupt-driven real time clock that is set to display on line 25 once a second. Occasionally the cursor will be left on line 25 after updating the time display. The next text then gets scrolled on line 25, a real loser! Or, one of the cursor addressing characters will show up on the screen on the line that was interrupted. Possibly the time-updating routine needs to do some padding before returning; I haven't tried that. Does the rom-clock develop this sort of glitch? 5-Oct-82 21:56:25,1021;000000000001 Mail-from: ARPANET site MIT-MC rcvd at 5-Oct-82 2155-EDT Date: 5 October 1982 21:49-EDT From: Jacob Moskowitz <JMSK at MIT-MC> Subject: "Super 19" ROM & DEC EDT v.2 editor To: H19-PEOPLE at MIT-MC It works very nicely with EDT v.2 (& therefore, I assume, with KED) in VT-100 mode. It even has some adavanced video VT-100 features, such as different cursor form (eg, underline) & cut&paste buffer identification (eg, local reverse video). The sfw whitescreen seems to suffer more from tearing than the hardware mod, altho Bob Todd of ETS (the distributor) tells me that the hi speed mod will cure it. But then it would presumably also improve the hdw whitescreen, too. The ability to Hold Screen Scrolling locally is very nice, since Hold Screen mode does not work for VT-100's in RSX. I am willing to check out KED specifically if requested -- I'm sure I can dig out an old tattered copy at work. sideways scrolling seems to help get around the 80 char. screen limitation. 18-Dec-82 0:11:23,3224;000000000001 Mail-from: ARPANET site MIT-MC rcvd at 18-Dec-82 0010-EST Date: Friday, 17 Dec 1982 19:07-PST To: INFO-CPM at BRL, H19-PEOPLE at MIT-MC Subject: Interrupting CONOUT with CONOUT => lost data? From: bridger at RAND-UNIX I've been using a clock/calendar that interrupts once a second and calls a service routine that sends the current time to the bottom right corner of the terminal screen. To do this it sends escape sequences to save the cursor, position it, and restore it. The characters are sent by BIOS calls to CONOUT. Randomly, the terminal would print the time but then fail to restore the cursor, or switch into reverse video or some other mode. Things got worse with a new terminal rom (the Super19 ROM for the Heath H-19) running at 38.4K baud, because this rom has a host of new escape sequences for extra modes, some of which reinterprete the standard ASCII characters. Having the terminal suddenly in never-never land is a real pain; to recover you have to go into off-line mode, and reset the correct modes. It turn out that the BIOS is sending characters to the terminal when it isn't ready to accept them. At least one gets lost; when the last- arrived character is an Escape, and its successor is overtaken by another character, the terminal switches executes a faulty sequence. For example: 'ESC k p' -- 'ESC k' is restore cursor, 'p' is data If 'k' is overtaken, the terminal executes 'ESC p' = reverse video ! My CONOUT implements hardware handshaking, using the H-89's 8250 serial chip. I assumed that this, coupled with handshaking by the H-19 terminal, would prevent dropped characters. NOT SO!! -- because the interrupt routine uses the console output data port the following sequence of events can and does occur: main program sends character to CONOUT CONOUT checks clear-to-send line: it's clear now clock interrupts saves registers clock routine sends a string of characters, filling the terminal buffer terminal turns off clear-to-send line: not clear now restores registers & returns character sent to terminal (!!) returns to main program In other words, the real-time status of the CTS line changes from the time CONOUT reads the line to when it outputs the character. Solutions: (1) disable interrupts before reading CTS, enable after sending the character; have the clock routine use a private version of CONOUT that doesn't enable interrupts. (2) Set a flag on entry to CONOUT, reset it on exit; when flag is set have the clock routine poll CTS until clear before returning. This complexity wouldn't arise if the 8250 had on-chip handshaking (like the Z-80 SIO) and didn't send out a character until the CTS line is clear. I guess the moral is not to trust an interruptible handshake! My suspicions that the Super19 ROM was at fault were unfounded, and I appreciate the time Bob Todd at Extended Technology Systems took to check out my questions. It is indeed a high performance addition to the H-19. With hardware handshaking and 38.4K baud, text can be redisplayed and edited very effectively. Now I'm curious to see what the game writers can do with it! 22-Dec-82 13:10:53,840;000000000001 Mail-from: ARPANET site MIT-MC rcvd at 22-Dec-82 1310-EST From: MADLER@MIT-ML Date: 12/22/82 13:02:04 Subject: 4MHz H89 mod MADLER@MIT-ML 12/22/82 13:02:04 Re: 4MHz H89 mod To: H19-PEOPLE at MIT-ML After finding the H19 mod great, I decided to do the 89 as well.

To: H19-PEOPLE at mit-mc Ok, I just got done putting my new super19 rom in my h19a, and have found a problem (I think) and I thought I would drop this one on the net and see what you folks have to say. Everything works fine, except when I use VT100 mode on our other vax running VMS. It seems when I run programs which use VT100 graphics, the characters are not correct. I realize the documentation says that 'wide characters, smooth scroll, 132 char line, and on board LEDS are not supported', however it says NOTHING about any problems with the heath versus DEC graphics characters. Does anyone know of any problems, if so how are they patched, OR... is my Super19 rom perhaps munged? Although the latter seems a bit odd, since the rom has nothing to do with character generator rom, at least not in any way I can see it causing this problem. THanks in advance for any help I receive. Of other note: I too have received my H100 system, although minus the controller board, *sigh*. After looking it over, it looks very nice, and I also have the extra floppy, extra 64K and the color chips and monitor. It is a very nice kit, and of course very well documented. I plan to have a BBS system up and running as soon as I can on this beast and if anyone is interested, I will give them the phone number to dial in. I am working on my own version of a unix look-a-like which will run UNDER cp/m-86 as EUNICE runs under VMS. So far it is about 80% complete (although not fully debugged since the code is being written on a cp/m-80 system) I may also market this product for a small fee, so anyone interested can contact me for more details on how it works. -Rich Fitzgerald (jazzy@aerospace) ++++++++++++++++
