Brilliant. A retrofittable idea. I'd vote for that one (if I had a vote).

I create a small extra board that can be connected to the existing board's AUX connector and mounted at right angle to the main board that slides into the box pictured above. On that board are switches for down/up, leds for talk/listen/disk and a small display (NDH-C02-16CZ-FSW-FBW-3V3). In addition to that a DS2417 RTC plus a 20mm coin battery.

Re: HP-9885M service manual.

Francois,

I would be interested in seeing that.  I have also successfully connected a 9885 to 9000-332.

Hi,

I just noticed that my original copy of the service manual for the HP-9885M/S is totally different from the one at the HP computer museum. It is a bit larger (7 chapters) and more recent (1981 ?) as it covers the 9835A-qB, the 9845 A-B-C and the HP-21MX. It also comes with a bunch of service notes (last chapter).

I don't think there is that much new informations. I could eventually scan it if there is interest.

I also have a 1982 print of the installation manual but a quick look shows no differences from the 1978 HP museum copy.

The one Marc uploaded is an older version that only includes 9885, the one on museum.net is the replacement that includes both 9885 and 9895.

I read the note, Marc. But LID's extensive use of Store(A$) went far beyond mere program retrieval.

Thanks Marc (for the scan) and Steve (for the implementation). A quick read through the manual raises questions about the missing routines, GROUCHO and ZEPPO. Is there another chapter in this volume?

Hi Marc,

Yes, half of the words in the System Programming ROM are devoted to the Store(A$) command. It was the only way to get a listing back into the machine from a saved ASCII printout. I never imagined that the Loveland Instrument Division would use it to programmatically combine HPL program subroutines into completed ATE programs, but it proved very popular for them. It seemed so simple: just jam a line into the keyboard buffer and smack the "store" key with a JSR call. But there were several exceptions to the ASCII program listings compared to the stored program and all of the exception checking ended up consuming half of the ROM.

Chris Christopher was in charge of the HP 9825 firmware effort and he was not at all pleased with my tinkering. He was afraid my abuse of the 9825's live keyboard feature would surface a latent bug in the main language ROM and so he repeatedly told me "Any bugs you find are yours!" None were found, until the 9825S/T conversion turned up a latent bug in my own code, but not in the Store(A$) command. It was in one of the special 98036A register-access commands I'd added. There were two writes misdirected at ROM locations. In the 9825A/B, writes to a ROM address counted as NOPs, so no damage was done. In the 9825S/T with full 16-bit addressing, RAM occupied those locations and the conversion team had to debug the problem of two RAM locations being mysteriously zeroed out for no apparent reason. "Any bugs you find are yours!" is what I told the conversion team. "It works fine on the 9825A/B."

By the way, the Systems Programming ROM was my first and only commercial software-only product. That's how we did it back then at HP. Design and debug hardware one day, run a lathe or mill the next day (under close supervision by the machinists who hated having engineers fooling with a power tool), write code the day after. What's all this specialization stuff?

It can be done, but pretty contrived as expected, I suspect not many people went through the trouble.
