I am looking for documentation for an IMSAI DIO/PDS floppy controller board set. The boards are revision 1.1, I believe. I have pictures here:
http://www.flickr.com/photos/106931119 at N08/
I eventually hope to connect them up to an IMSAI 8" disk subsystem (old Calcomp 142 drives), but I am interested in finding out if they will work with other drives, what cables I need, etc. Also, I want to know if there is some kind of monitor on what looks like a rom chip on the DIO card, and if so, what address it shows up at?
I have emailed Mr. Fischer at IMSAI.net, but haven't heard back.

I have one as well, tethered to a IBM 5170. I have pretty full documentation and also have the OS media, though I have never checked it out to determine if it works. I bought my 5364, with PC card and cable, on Ebay in 2004 for $101 from digitaldinos.com. Thought it was a pretty decent deal at the time . . .

I would advise anyone acquiring one to be sure they get the customer console adapter and cable with the system. The system has to be pretty permanently tethered to a PC. I believe the PC needs to be a fairly compatible XT, though I've so far failed to get mine to boot properly, so take my advice on this with a grain of salt. I also have the docs for one. Not sure they've made it to bitsavers yet, so might be useful. I believe other people on the list have the OS media. That's something I currently lack.

I've thus far been unsuccessful locating any TU-58 emulator "tap" files for
booting an old 11/730. Or any "tap" files specific to, or appropriate for,
the 11/730.
Is it just that my google-fu is bad, none are posted, or possibly none
exist?
Thank you for any guidance or commentary that anyone cares to offer,
paul

I'm currently pulling the CIS-local code out of DECWAR in aid of installing
it on the DECsystem-1070 (KI-10 #587) running at the museum. It would be
very helpful to (1) talk to someone who programmed in Macro-10 on the CIS
systems, or (2) at least find someone with UUO and programming environment
manuals. (I don't see either CIS or CompuServe on Bitsavers, but I may be
missing something.)
Does anyone reading CCtech/CCtalk want to confess to having experience in
these matters? Privately or publicly?
Thanks,

I have three and a half... but I acquired it almost for free...
A fair price is near to zero :)
You need also the special cable and the PC receiver, besides PC software
and a suitable host pc acting as a console (usually an XT).
I have some software disk images, also...

Hi Tom,
thanks for sharing your experience with the list !
There are two 1000A Alphaservers in my collection also waiting for a revival. They had been used by a german TV-sender to broadcast publicity. I think I'm well prepared now when I'm going to find the time to fire the systems up regarding pitfalls known about these machines.
Kind regards,
Pierre

I had that file sitting around from when I'd played with ITS some ten
years ago, so I've uploaded it to archive.org:
https://archive.org/details/KLH10-PI-ITS
The instructions I actually wound up using to build an ITS system were
these ones, though:

I have 81 more P112 boards, so I need 81 more boot rom chips. I managed
to buy Atmel 28c256 parts (which are eeprom) rather than the 29c256 (which
are flash) parts. Is there someone out there who wants to do a swap?

Is the 12V rail present at the power supply connector? If not and the other
rails are working, it is likely that only a very small number of components
and could be responsible. If the problem is intermittent, it is likely to be
due to a bad solder joint between one of these components and the power supply
PCB or a bad contact in a connector.
If you trace the wire carrying the 12V line into the power supply, it should
be possible to find which rectifier and reservoir capacitor produce it from
the chopper transformer. The only other components involved are likely to be
a filter choke, a fuse or circuit protector of some kind and maybe a low value
resistor to sense current draw. Identify the components involved and check
that they are all securely soldered to the PCB. Try tapping the components
involved and the PCB in their vicinity with something insulated while
monitoring the 12V rail to see if the problem can be provoked.
Be very careful to avoid touching or short circuiting anything on the live
side of the chopper transformer and the mains input side of the power supply
in general if you have to run it with the cover off.

Peter Coghlan.
I'm looking for the set of BASIC ROM images for the HP E130X 75000
mainframe. Visually, the unit looks like this:
http://www.dontscrapit.com/Vermont-/Hp-75000-series-b-mainframe-w-E1326B-me…
some don't have the front panel. If it comes with a floppy drive, it
is
likely to have the BASIC ROMs. If anyone has one of these and can check the
ROMs, please let me know. I believe there are only two EPROMs that contain
the BASIC image.
Thanks!

The simplest thing is to buy a little NiCd or NiMH battery pack containing
three cells, designed for use in cordless telephones. It may even be possible
to find one with the right connector to plug directly in to the VAX.
If you can only get non-rechargable batteries, you could use three 1.5V cells
and two silicon diodes all in series which will prevent charging as well as
dropping the voltage from the battery by roughly 0.6V to 0.7V per diode. (Two
cells and one diode might work too.)
Whatever batteries you use, don't leave them in the machine when it is not
being used for long periods.

Peter Coghlan
I think we should all get together and send Tony Duell a new spell

I have been working to validate the FreHD hard disk emulator (
http://www.vecoven.com/trs80/trs80.html) with the Kaypro.
Good progress on the 4/84 with the Advent TurboROM but I want to validate
it on my 4/83 also. (Unfortunately finding a 4/84 is not so easy.....
Kaypro are not very common in New Zealand so I am stuck with the 4/83 but
also very keen to try and get it going).
Searching for the TurboROM for the 4/83 has been unsuccessful. The
available ROM's on the internet are the 84 version (8k). I have seen
several requests for it on different sites but no ROM unfortunately and no
"hey look what I discovered" posts.
After reading the TurboROM notes in this really good overview document (
ftp://ftp.barnyard.co.uk/cpm/walnut-...O/TURBOROM.DOC) and some work with a
disassembler on the '84 ROM I have confirmed that it is specific to the
machines with the 6845 video controller so modifying the 4/83 to use an 8K
rom isn't enough.
Hoping that someone on the list may know a source for the Advent TurboROM
for the 4/83.
Regards
Andrew
