If my house were on fire and I had to pick what to save, near the top of
my list would be my MicroVAX in a BA123 enclosure. It is by FAR my
favorite computer. Sadly, there was a tragic accident and the
ventilation louver, just about the power switch got broken. I know, I
know. How could this ha
For 2.11BSD on the PDP-11, in the stand alone utilities that are found on
the installation tape, the storage devices are named:
dn(x,y,z) where dn is the mnemonic for the driver, x is the controller
number, y is the unit number and z is the partition on the unit. So the
first partition on the firs

I ran into the famous Michael Holley (www.swtpc.com) at VCF West and had a
pleasant conversation. I've emailed him several times at the address on his
web page, but haven't had a reply. I'm wondering if he ever hangs out on
cctech an
I've been looking for an SS-30 bus floppy controller for some time now.
Examples would be DC2/DC3/DC4/DC5, but I would also be OK with a Pertec

I have the following 5-1/4" Drives that I would like to get rid of. These
have all been working at one time or another, but I have no idea what
condition they are in now.

Hitachi DK516-12
Maxtor XT-8760E

I also have the following QBUS cards to part

these boards working at one time or another but I can't speak to their
current status.

Not exactly the same thing, but I've run several different versions of
NetBSD on both a real 3900 and on SIMH. I have not tried current, but I
have tried the 3 series, the 4 series and the 5 series - all seem to
work well. In this context, "well" is defined as (in order of decreasing
importance):
There's been a lot of discussion of late about replacing power supply
capacitors in DEC power supplies. I have a BA123 and I believe that it uses
an H7260 power supply. I feel like it might be a good idea to replace the
capacitors before a disaster occurs. I haven't been able to find a
schematic fo
I hope this qualifies as classic computing...
Does anyone have the pin-out for the P2 connector on MVME processor boards?
I think that the pin-out would be the same for MVME147, MVME177, MVME162,
etc. and would mate with the P2 adapter board.
Anyone familiar with the SPF file manager on Microware OS-9?
I have an MVME162 processor and for no good reason, other than an
intellectual exercise, I've decided to try and get OS-9 68000 running on
it. Mostly this has been a pretty simple exercise, since the necessary ROM
images are on the Inter
Does anyone know if any of these are still available for OpenVMS VAX?
I'm moving and I need to clean out a few things.
I have a Sun 3/60 with no keyboard/mount/monitor/hard drive - just the
pizza box. It net booted NetBSD, but that was many years ago so YRMV.
