Hi all,
I have a HP 1640B that I'm trying to get to work. However I can't find any information about it, and while the machine itself it straightforward enough (and I remember enough from when I was using it in my first dayjob) I can not find anything about how to use the GPIB interface that it has.
The reason I'm interested is, we've finally managed to add GPIB support to the PDP2011-MINC fpga implementation, and I'd like to test against a different target than the relatively modern Philips/Fluke counter I'm now using. And the 1640B is the only other GPIB instrument I have...
The HP doesn't seem to know the ID? command (that causes an error message on the screen). It does respond to a newline (the standard is-this-listener-present test that the MINC code implements), so at least something is working.
Does anyone here have any docs on the HP 1640B? It'd be very helpful at least to know which GPIB commands are implemented.
thanks in advance!

Hello All,
I got a CDC 152 Logic Card Tester.
This one does have some kind of a patch panel to configure the cordwood module test procedure.
I did not find any reference to this unit as well as documentation while querying the internet.
Any hints to docs?
Best

If I remember right I was told back in the early 70s by our IBM CE that physical damage could be done to our model 30 or 40 if we ran a program that did an Assembler instruction, B * For those non-Assembler people that is an instruction to branch to the location of the instruction. I think it might have caused a heat problem in the core or CCROS or TROS.
Possible? Or is my 76 year old brain hallucinating?
A lot happened in the computer industry in early Nov. in the past: Intel's
x86 PC architecture was born; lo & behold Windows ME was released upon the
world; for the corporate in us the IBM Portable Computer was introduced.
The PC world hasn't been the same since.
Happy computing,
Murray 🙂
Hi everyone,
Does anyone have the source for the ZRQCxx formatter? I have found a pdf
for ZRQCE0 but am curious if the actual source code for that one, or ZRQCH0
is available? I'd like to make some changes to the UIT table.

You'd think an IBM operating system on an IBM ThinkPad would be easy-peasy
- but good grief, it's taken me over a year to finally get a magic formula
that works. Not too new, not too old.... (and yes, I have ArcaOS too, but
I wanted an OG 1994 install)
One interesting thing I found is that OS/2 can actually run SecondReality
(in full screen, but it suspends it when I ALT-ESC to something else) --
including with SBPro audio. I couldn't do that with WinXP yet (same
hardware), even though trying explicit DOS settings. I may tinker some
more on that, but rebooting to "MS-DOS Mode" in 95/98 can changing EMM386
from NOEMS to RAM then SR works.
I'll do a write up on the adventure soon-ish, I'm still trying to figure
out the TCP/IP settings stuff for OS/2. My first experience on the
Internet was "borrowing" my sister's credit card and racking up $100 for an
afternoon of web-surfing on dial up, with OS/2 Warp in 1994. A graphical
Traceroute was so neat to see, a graphical Gopher, and some early web
sites. Frankly, that day I fully realized that "BBS's are done for" (or
cute ANSI couldn't compete with HTML).
I paid my sister back, eventually. At the time I thought it was just an
activation gate, didn't realize there was a per-minute charge. Sorry sis!
Don't leave your card out on the table :P

Hi guys,
I've got a bunch of TMS32020 and two TMS320C25 Chips and I want to play
with them a little :-)
Is the old DOS (orf VMS?) Software still available from somewhere?
(Yes, I have an VS4000-90 under the desk..long time ago since I've last
booted it, but ...simh also exists).
I'm looking for assembler, linker and the simulator that was abailable
when those chips came out (1986...) but I can't find any occurences
of that old stuff anymore.
Was a C compiler available for those old DSP's?
Regards,
Holm

Sorry you'll notice also on the lower half of the front is an aluminium cover that detaches with a couple of screws, revealing another card with additional labelling on it. Also have a look around the inside of the case. Any of those thin, printed strips are where you'll likely find one (or more) of these 005- series numbers. On my unit, the '6098-4' label can be seen on the external rear of the machine, adjacent to and below where the label describing the power characteristics is located.
