Hi there
I recently had a mad hankering to add a SunPC card to my Sparcstation. A lot of you will be familiar with the SBUS cards with a 486 or '586' processor.
Does anyone have one spare they would like to part with? Please PM me if you do.
Anything really not at all fussed.
This sort of re-creates a setup I had as a post graduate when I had a new 486DX2 alongside a Sparcstation 2, or at least had access to them. Both were pretty amazing machines at the time.
I do remember benchmarking these two machines running similar C software I'd compiled up (a simple electromagnetic simulator), and it was noticeable that the sparcstation was at least twice as fast.
Hello all. I looking around for a Logic Analyzer for doing (mostly) DEC QBus/UniBus stuff. Being the way I am I want something with enough lines to handle the most of the signals so I'm guessing something with roughly 80-ish channels. I think that lets out all/most of the USB based LA. I've looked around and it seems the the HP/Agilent 16700 series (16700B/16702B) are probably what I want. I've also seen the 1670G which also seems quite doable. I've seen a lot of posts at the EEVblog and it seems I missed possibly the golden age of 16700 LA by a few years price-wise.
What I'm wondering is if there is something specific I should be looking for, or opinions on which LA is more suitable. Or even if there is a different make of LA to look for.
Thanks in advance for your help

Hello All,
I am working to get my two microvax systems working, I have a couple of
microvax 3800 systems.
While I am waiting to get the real hardware going, I would like to set up
simh with vms to use for testing.
I don't really need the latest version of vms, any old version with tcp/ip
would work. I do have about 16 dumb terminals i want to run as a lab and
connect to the vax.
Can anyone provide guidance on this matter for setting up and install of
VMS in sinh? I realize that there was the openvms hobbyist program, but i
may want to grab an older version of the os if it will run smoother on the
older hardware.
Open to suggestions, I hope to post back with some pictures once the real
vax 3800 hardware is running.
Thanks,
Devin D.
To clarify a couple of things in response to queries: my time for
divestment is "not yet"--but rest assured, when it arrives, I will
certainly see who wants things from my assortment (don't get too excited;
there's nothing super-rare or valuable in it, and I've always been more
concerned with restoring functionality than maintaining period-correctness;
I am one of those collectors who restores stuff to play with it, not to
then put it in shrinkwrap and preserve it for some uncertain future). And
should that time arrive suddenly, well, argh, I've been putting off making
a will too long, but I know who I'm going to put in charge of "everything
computery," and I trust her to make good decisions about the things she
doesn't want.
My understanding of sqlite (and it could be wrong) is that concurrent
writes aren't supported, and reads should block if a write is in progress
until the write completes. In practice it seems like most things are
one-sqlite-file-per-process and if that process is threaded, one would hope
the programmer understands what they're doing well enough to make it work.
There are fairly few cases I've seen where a single sqlite file is shared
between unrelated processes, which would take filesystem locking working
correctly to ensure correctness. Which is generally OK for local
filesystems, but NFS is still a bucket of worms when it comes to locking
behavior, and the number of people running systems that genuinely
understand NFS has been declining for decades. (I do not count myself
among those people.)
I have a Gesswein MFM emulator from decromancer.ca; who offer an adaptor that yields a 2nd MFM data connector.
I'll use mine in a Microvax 2000. Does anyone know how to hook it up as two MFM drives in a Microvax 2000?
The vendor sold a 1in high adaptor box, BA40A, with DD50 connectors to a second cabinet (same as CPU box) for a second drive.
DEC configured both primary and secondary drives identically (drive 3, IIRC). The Microvax 2000 Technical Manual gives the pinout from the mother board to the MFM/floppy daughterboard, but I can't find the pinout from that daughterboard to the cables anywhere.
I've been looking for a BA40A, for some years now, to trace the pin layout for a 2nd drive. Does anyone know it?
Has anyone successfully configured a single MFM emulator as two MFM drives in a Microvax 2000? Or to an RQDX3?
Been thinking about it a little recently, and, no, I definitely don't plan
to send my stuff to a scrapper. I have some younger friends with an
interest in retrocomputing. They want my stuff when I'm done with it,
sure. And if they want _just a little_ of my stuff I'll probably strike a
deal like, "you can have the SGI Indy if that box of IDE drives goes with
it, and you aren't allowed to throw it away until you're somewhere I'm not
going to see it by the side of the road."

Mike,
Well sadly I have no PDP-8 parts. I do have a few bits of Q-BUS PDP-11. Probably enough to build a complete 11.
I am also in the UK ….

I will gladly give a nice warm loving home to any PDP-8 equipment and parts that you have.

Gentles,
The problem is I have stuff no one wants. Large plotter, dec writer in need of repair, Large Alpha server....
Suggestions?

This is almost an impossible question to answer (!) but it might be worth mentioning Pimcore. This is an open source master data management tool, meaning that it supports both schema (data model) design and generation/design of UI elements via a reasonably decent management interface.
It might even be overkill for this particular use case., but from memory the web UIs that it generates don’t depend on front end libraries / Angular / React etc & so may work with older browsers.
Perhaps another option is LibreOffice Base?
Chris,
I would be interested in getting a copy of the SSPS/X software for POS. I have a manual for SPSS/11 and would love to try to get the software running under RSX11M+ if possible.
Thanks,
Mark
