Question for any Vax wizards hanging about:
I just received a VAX 4000/600A in a BA400 rack mount chassis.
It contains no disk. I'm having a little trouble sorting out part
numbers and abbreviations online, but I think I'm looking for one or
two RF72 or RF73 DSSI disks in ISE packages.
If I'm barking up the wrong tree, cluestick whacks to tell me why
this is a bad idea or impossible to find/maintain, or what I should
try instead, would be appreciated.
The box does have a KZQSA controller, but I like the neatness of the
ISE modules.
Thanks,
De
I have the PDP-8e Intro to Programming (1970). I'm not exactly sure what
you're looking for. If you think it's in there, I'd be happy to look for
you. However, all I see here are IOTs for TU58, drum disks, scopes,
recording voltmeters, TTY's, and etc. Nothing that explicitly says RX01.

I would recommend posting to cctalk at classiccmp.org. this is an International

All:
I just recently upgraded the network cabling in my house to 5e
as part of some new construction, and I also upgraded the networking
components. Now, all of my normal machines run at 100 full duplex. Anyway.
The strangest thing happened to my Mac IIci - the Ethernet
connection no longer works. I don't even get a link light on the new switch
(a Cisco/Linksys switch). However, when I plug the Mac into a plain old 10BT
hub and then uplink it to the switch, I at least get a link light.
Nothing else works, though. The router doesn't show the Mac obtaining an IP
address, and the ci doesn't see the AppleTalk zone that's on my NT Server
box. In the previous configuration, everything went through a 24-port hub.
Does this problem resonate with anyone?

I have one or two of these around here. I don't know which overlays I have,
but if you need any of the info on them, I'll try to dig them up.
Thanks, Paul
I spent last evening with a friend hacking on my HP-2112A. We got it up
and running! Still no work on the peripherals. It does have a sticky bit
that I've not yet tracked down, but I presume that's another bad
connection someplace. At any rate, I got a simple delayed binary counter
running that dumps to the S register.
I powered up the 2108 as well running a chaser routine:

Assembly sources are in that same directory if you are curious.

One step closer to running ACCESS on real hardware. =)
It looks like SIMH has IPL issues under Linux and probably other OSes. I
can get ACCESS running in windows but not under Linux. I'll spend some
time debugging that soon.
I don't have the hardware for the IPL so I'll need that someday. I
understand that I need 4 12566 cards and some custom cables. I bought a
few cable ends from larry of ebay and I have these two cards:
GND TRUE IN/OUT - 12566-8001, 12666-6001 907 22
+TRUE IN/OUT - 12566-8001, 12566-6002 907 22
But I only have 2. If anyone has others that they might want to trade
boards for I might be interested. ;-)
At some point I'll likely need the IOP firmware but I know Jay has it so
I'm sure we can work something out there.
Also need the breakout panel for my MUX set at somepoint. At least I
need the edge connectors. They are the same size as the normal edge
connector, but use a higher pin density.
Leads welcome!

I have a lead on a Sun 3/50 workstation, dead Sun monitor,
non-Sun working monitor, 2 SCSI boxes, keyboard, mouse, cables,
etc., probably still working.
And a Sun 3/260 floor model with monitor, 2'x2'x6' 9-track tape drive
(Pertec interface), keyboard, mouse.
They're located in Madison, WI. Free for the hauling.
Due to size and weight, I may need to pass on these. If you're
interested, I can point you to the owners.
I'm also hunting for a table-top 9-track reader, SCSI. I need to
read a dozen or two tapes and move the data to conventional media.

Use a Solid State Relay with the proper rating at the AC switching side,
and operating on low-voltage DC at the input side. Nice to have is a SSR
which switches the load at AC voltage zero-crossing.
If you install the SSR at the rear side, you can keep the AC power leads
very short between the inlet, SSR, and the power transformer.
Now, you need a DC source, which is switched to the SSR input from
the console front side. Most SSRs operate at the input range of 3 - 32V,
so either install 3 NiCaDs, or install a small transformer with a bridge
rectifier and an electrolytic capacitor to smooth the DC. If you go for the
second choice, get a good quality transformer as it might be powered always.
If you go for the NiCaDs, you might consider a simple loader that recharges
the NiCaDs when the AC power is on the main transformer (unit switched ON).

Onderwerp: AC power on front panels
I'm playing around with my relatively new IMSAI and I was
pondering the following. The unit is constructed with the front panel power
switch unconnected and the corresponding terminals on the power supply board
jumpered together. There is a mains switch on the rear panel which takes the
place of the front panel switch.
While for safety reasons I cannot disagree with the approach -
it's plain stupid to put uninsulated mains voltage in a low-voltage area
(and unpassable by UL evaluators I'm sure) - it detracts a bit from its use
because you have to reach behind the unit to turn it on.
Has anyone come up with an elegant solution to being able to use
the front panel power switch while keeping it safe? I was toying with some
sort of low-voltage circuit (small LV transformer and relay, with the front
panel switch in the loop on the coil side). Another idea I had was to hot
glue a dielectric insulator board (that gray cardboard kind of stuff) over
the parts of the front panel that would be exposed.
Ideas? Too much time on my hands?
