I've inherited a VW320 but it is missing the drive cage.
If I can get it running, I'd also be looking for some
extra memory for it (wacky 40 bit? modules).
I *think* I can replace the single CPU with a pair
of off-the-shelf "matched" processors?
Or, is this box not worth the time to get it running?
here is the updated zipped RL02 disk container.
It has Zemu 1.10 just released by Johnny.
I changed the hex fields into octal fields ...
You might first try the earlier sent zip, and then
this new one, to see a possible difference.
If you want a zip file with the original Zemu 1.10
release from Johnny (without my hex->octal adjustment)
just ask, and I'll zip it for you.

Price (?50) looks a little on the high side but does include 26 tapes
SCSI interface - almost certainly really HP tho' described as "SUN".
I have bought from company before - they seemed reasonable.
This (very heavy!) drive will almost certainly need manoeuvering down
a flight of stairs. Parking is tight but should be possible.

Enterasys is still quite alive. http://www.enterasys.com
They recently moved from NH to near (or in) the old Andover plant.
I'm still in touch with Dave Nelson, who is current co-chair of the
IETF RADIUS Extentions Working Group. Dave worked on DECservers
while in LKG. Looks like they are using the RoamAbout(r) name for
their wireless stuff.
Catalog info out. It is item number 1

Going to be an interesting sale. I used to go to this regularly 10
years ago. I see they have online bidding now.
I'm totally unfamiliar with the VW320 (which means this is undoubtedly
useless advice), but at least some of the SGI Visual Workstations were
secretly Tyan Thunder 2500 (aka S1867) based, and could be flashed to a far
more forgiving Tyan BIOS. Perhaps there's a similar sheep in wolves
I've got a hex dump here of an Assembler/Text Editor for the 8080,
called (IIRC) ATE. It's what I used on my first computer (8080 S100 8k
+ KC tape). It's about 4k, so I had 4k for source + object, or it could
work as a 2-pass assembler reading the source off tape.
Does anyone know about this? Is it of interest to anyone? I could
either type it in, or scan the listing for someone else :-) The code
would need patching for console & tape I/O, and I don't have any
documentation on how to do this, or even how to use it, but it can't be
too difficult. Forgive me, it's been almost 30 years!
I've been quiet lately, see http://www.ljw.me.uk/porsche for an idea

If there was a dead data buffer, how on earth could the machine sucessfully

I am having some trouble finding the right diagnostic for basic instruction

I think I see what you're saying. After I try the first two tests, I will
need some clarification on this and post again :)
