All,
I'm looking for a Cromemco System Zero, doesn't matter if it's empty or not. Please contact me off-list if you have one to sell/trade or know of one!
Thanks,
Jonathan

Don't know, but doubt it. Some of the disks have probably been used
for other purposes since the VAXen went away more than 20 years ago.

While possible, I think hardly likely. I don't even remember what the
appliance was. Something DECish.

I have often wondered about the people we find in the various
DEC Processor (and other) books. Were they models in staged
photo-sessions or were these candid shots from DEC facilities
and if so, can anyone identify who they might be.
Looking thru some of the books again I came across an interesting
photo on page 42 of the 1981 pdp11 processor handbook / pdp11 04
24 34a 44 70. If you take a magnifier to the picture you will
find the system presented in that photo is not a pdp11 but a VAX. :-)
I wonder what other DEC systems are contained in these photos?

I just got a pdp-11 to boot and it seems to have rt-11 installed. How do I do an orderly shutdown? Google has info on simh but this ain't that.
Thanks!

I'm trying to build some prototype Tomy Tutor cartridges of my own but I'm all
thumbs in KiCad, and while prefab ones exist that I can just add an EPROM to,
they're in ExpressPCB and PCBWay wants Gerbers. This Mac won't run ExpressPCB,
or at least not in a way that wouldn't involve a significant expenditure.
Is someone out there with a copy of ExpressPCB willing to convert these to
Gerbers I can upload? They're quite small so it should be a simple task. If so,
please contact me off-list with many thanks!

I got a vic-20 in a painted case, with a biacom label, and a modified
VIC-1110 8kb memory, where there have been added a 8kb eprom have been
to the left side where the additional 8kb could be
installed.
https://telefisk.org/biacom_8kb_a000+8kbmem.romhttps://telefisk.org/biacom_basic.txt
The autostart rom code, that disables runstop, moves and starts basic ,
does seem to initialize everthing like a normal start does.
Adding the rom to vice without reset and do a poke 44,161, to move the
basic start to 41216, one can look at the code.
The software seems to be made to print signs, but I havent had much luck
getting vice to print, I only get a blank page.
Looking at the code
line 60
# Line Spacing of n/216 inch chr$(27) "3" chr$(n)
line 61
# chr$(14) One-line Expanded Print
# chr$(20) cancel expanded print
line 68
# single density 60dpi line lenght 135 + (256*1)
does look like it match up to the commodore/epson codes, printing the
basic list with open1,4,7:print#1:cmd1:list works in text and
graphics for the mps80x, but not from the basic code there.
Wonder if I am running into a bug with the print emulation or it was
made to use a different printer ?

So, sorting thru stuff I came across this white elephant again.
I never found anything to positively identify it but I always
assumed it was some kind of buss extender. One board is fully
populated with chips and the other connected together with a
ribbon cable is totally passive.
But this time I found the funniest thing about it. The passive
end has a sticker on it with an expiration date. I have to admit
I have never found an expiration date on any of my PDP or VAX
hardware before. :-)

It's a VAX 4000-300 (KA670) in a BA440, so it has two DSSI, ethernet,
the usual switches and LED display. I can switch ethernet between AUI
and BNC (the green LEDs change) and I have known working DETPM
AUI<->RJ45 interfaces, so ethernet may be OK. I have found one panel for
a KA650 (uV 3500/3600) that has an OK connector but is otherwise a bit
toasty, so I'll try carefully removing that tomorrow. If that goes OK,
then I'll remove the MMJ socket from the VAX 4000 console SLU: it's dead
so there's not really much risk here as long as I'm careful with the
PCB. At least I could then tack on 6 wires and find a way of
interfacing. I do have at least one H8584-AC, which is an MMJ socket and
an RJ45 plug. So with a bit of measuring I could probably find an RJ45
socket and rig up some temporary franken-console. Or, if the KA650 donor
is really too far gone, and its socket survives half a dozen cable
insertion-removals with no harm, then I could just fit that in place.
If the console ethernet doesn't work, I think I can drop in the DELQA
with appropriate handles from the KA650 system ... I think that the
BA440 Q-bus metalwork and the BA213 metalwork are compatible. If not I
have one Q-bus DELQA panel and I'm sure that neither the VAX nor
anything else in there with it care too much about RF interference these
days!
I can find new MMJ plugs all over the place (admittedly I'm assuming
that Mouser and Farnell could actually supply them!!) but the
corresponding sockets seem to be lost to time. Or at least they remain
beyond my goolge-fu.
