If anyone has dumped the ROMs from the HP 9895 (8-inch) or 82901/82902
(5 1/4-inch) HP-IB disk drives, which use the Amigo command set, I'd
appreciate copies of the images, ideally along with the HP part
numbers of the EPROMs (probably 09895-xxxxx and 82901-xxxxx).
For that matter, I'd be interested in ROM images from any of HP's
other HP-IB disk drives, floppy, hard disk, or combined.
Also ROM images from the 9114A and 9114B HP-IL disk drives. I already
have one ROM image each from the 9114A and 9114B, but there were
multiple firmware versions.
Thanks!

I wanted to extend my thanks to the organizers of this event, and to Jay in particular who showed me the way around bringing up a cantankerous HP 1000 E system in real time, and somehow never got tired of my newbee questions.
And the Chinon FR-506 5.25" drive that I picked up there for a very reasonable price, unlike the one I had bothered you about in a previous thread, actually works!
All in all a very worthwhile way to spend award mileage on a trip from California to Chicago...

this is a good deal if the paper path isn't scratched up in them.
the CW model has a 11" width feed and can scan a sheet 6 feet long.
these are the ones I've been using for 5+ years
just don't need any more right now
Has anyone else come across this? My TK70 wouldn't eject, and having not
had one before, I didn't know just how tactile the unload button should be.
After further examination and prodding, I determined that the button was
pretty much stuck and refused to come out.
Taking the front off and exposing the board indicated that the button seems
to originally have been rubber, which is now a nice black tarry goo. I
think I can replace the button with a standard tactile push button, this
time without any rubbery material.
Hopefully that's my only issue.

This is off topic, so-to-say, but computer languages can be esoteric:
It's the 150 anniversay of L. Carroll's "Alice's Adventures in
Wonderland." May I dare say most people, including myself here(I
studied languages like BASIC, COBOL & PL/C, know very little about the
programming languages that make old & new computers do what we wish
looking backwards? Logic, like "Alice's...", can elude us at any
time...
Happy computing.

I'm making good progress on the MEM11 firmware. I spent the last few days
re-doing the firmware build environment. Previously, it would build all the
files each time. Now there is a proper Makefile (even though it takes about
a minute to build everything). I realized that I needed something
better than
what I had because there are multiple targets (emulator, FPGA eval board and
the MEM11 board itself). Right now I'm focused on getting as much debugged
on the emulator since it has a reasonable debuging environment.
I've also integrated various test programs into the build environment
and use
various low level code as part of the main firmware for hardware access.
This "kills two birds with one stone" since it tests not only the
various hardware
functions it also allows me to debug some of the firmware separately from
the full code base.
At this point, the emulator fully supports all of the J1 instructions
(and they
all work too!). In terms of I/O (that will be part of the MEM11 board) it
supports LEDs and various configuration inputs, FRAM, UART and timers.
The biggest risk that I'm taking is that the UART is emulated as being
directly exposed. On the MEM11 hardware, the UART will be connected
through a SPI interface which requires that all accesses to the UART are
asynchronous transactions.
The biggest piece of work remaining on the emulator will be emulating the
Unibus interface. The work here will mainly to create a means to script
various Unibus transactions.
However, before doing that, I'll be testing out the boot loader code and
the configuration firmware since none of that is dependent upon the
existence of functional Unibus hardware.

Folks,
Possibly a long shot since I think the MPF was only a UK/Europe thing but
I'll quite happily be proved wrong. I've had a chap asking for a scan of
one of my manuals that would necessitate partial destruction. Anyone got
the IOM-MPF manual? It's a 6k RAM expansion board for the MicroProfessor
MPF-1P seen on my site here:
http://binarydinosaurs.co.uk/museum/multitech/iom-mpf.php
(Ironically today I'm working in a building that has a proper book scanner,
but all the staff that operated it were 'let go' earlier this year)
Cheers

It's time to start on the Data General stuff I've had forever but not yet
restored :) This time much of it has finally made its way into the workshop
so perhaps there will be some progress.
Pictures of the initial set of racks to work on are at
https://www.flickr.com/photos/131070638 at N02 , but there's more DG racks with
devices that can be used at both houses.
Trying to decide where to start really, and what pieces to use and what to
trade off (I'm not really familiar with DG stuff, yet).
At the least, I know I don't want/need the large FPS (Floating Point Systems
model 100R) box. Anyone have interest in that part?
If folks have docs that might help but are private, I'd appreciate a little
access or pointers. My initial questions revolve around what boards from the
Nova 4, S/130, and S/200 can be interchanged if desired, I'm still trying to
decide which cpu to keep and which peripherals. Time to read what docs I
have and scrounge up ones that I don't!
I know I got keys with these systems, but don't see them anywhere. The
6021/6023 tape drive uses vacuum columns, that will be fun. The TP1 is an
awfully cool retro printing terminal. The 5821NT terminal has (by a large
margin) the worst screen rot I've ever seen. The 6125 tape drive is in an
odd "desktop" stand like I haven't seen before.
Let the fun commence.
