The "FIRST PC" and personal timelines (Was: And what were the 80s

by allisonp＠world.std.com

<Ah, but what was the first Microcomputer (including at least a monitor with <bitmap display, some sort of disk or floppy drive, as standard features, <and 'personal' in nature)? That could be a pdp-12 or a POLY-88 depending on your point of view. Clearly a northstar horizon with a compucolor would fit that requirement though at that time useres didn't feel the need for more than a good terminal. That would be 1978. Why bit mapped monitor?

I believe he envisioned them as a way to move through Cyberspace more efficently than with a mouse. So that would pre-date PARC, being at Arpa or at Tymshare. Mark.

z80 timing... 6502 timing

by gregorym＠cadvision.com

Now I know that many people didn't consider it a reasonable computer, but the TMS-9900 did make a memorable appearance in the TI-99/4/4A of blessed memory - 16K if I recall correctly. Once you added a PEB, RS-232 card, 32 K memory card, 2 HH DS/SD floppies and an Extended Basic cartidge, it was a fine computer. So bite your tongue.

This seems very melancholy to me. Delightful that you're there to preserve the machines for posterity, but sad that prodcutive machines are being shut down after long service.

PDP-11/44 CPU Configuration

You go down to the most basic configuration >> possible, and then add parts one at a time, testing as you go. >Well, with the exception of the DELUA, and RAM everything is configured the >way it was when I got the machine, but that's a good point. I hope nobody takes it as an insult when I try to encourage them to take a system down to its bare-bones and build it back up step-by-step, but this really is the best way to debug a system that one knows little about the history of. Just because something is written on the sticker on the cover of a system about its configuration doesn't mean that it was working in that last configuration! In particular, with Unibus machines you have to check the presence of the NPG jumpers on the backplane if you have the slightest reason to believe that the configuration has been meddled with in the slightest since it last worked. A single mis-placed jumper anywhere in the system can cause the entire system to lock up when the first DMA attempt is made... Tim.

Programming fixtures for Panasonic HHC

by rcini＠email.msn.com

Hello, all: A friend of mine has a small quantity (~30) of adapters to enable one to program the EPROMs used in the Panasonic HHC with a standard EPROM programmer. The adaptor houses the 8K eprom, most commonly used is the MCM68764 by Motorola, but a special crimping device is used on the chips before they can seat in the HHC proper. If this was not the case, you wouldn't need the special insertion socket to burn chips, you would be able to seat the eproms directly into the ZIF sockets on the programmer being used. These adapters were supposedly hand-crafted for the purpose. Asking price is $15@ plus shipping from New Jersey. If anyone needs more details, e-mail me privately and I can hook you up with the guy selling them.

And what were the 80s like for you? (Was: z80 timing...

by edick＠idcomm.com

In '76 a couple of my friends and I were ogling at ads for Alpha Micro and some self-contained Z-80-based unit from CompuTrol or some such manufacturer. The latter had a built in display and printer, though I don't recall what kind of display and printer. It might have been an EPN9120-based printer, but it appeared it was a small CRT from the ads. It might have been a small, e.g. 20-character alpha-numeric LED display, though.
