Re: Unix-PC

The Unix-PC has found a new home in the hands of someone I am sure will enjoy and appreciate it.  I would expect him to show up here sometime with questions as he tries to revive it.  I tried booting it and while it booted fine from the diagnostic floppy and things like memory and CPU tested OK

SGI Indy power supply: identify this diode?

After a recent power cut and a series of glitches as the power was restored, one of my Indys suffered a PSU failure. It's a Sony APS-81 171W unit, SGI P/N 060-0008-001. I've found half a dozen damaged parts, and I've identified a 150R 1W metal film resistor (R135), two trannies (Q105, a

LSI11 CPU Microm

I was trying to put together a minimal PDP-11/03 using a quad width M7264 CPU and got nothing, no ODT prompt.  I'm not sure the board is working. Searching the internet I came across this page which described a M7264 CPU board with a 'bad' MICROM
