Re: SGI Indigo, WTB Power supply? Burning smell?

I have a indigo that is not getting much use. I believe it has the R4000 with the better power supply, and maxed out ram.(whatever that may be, i want to say 192 Mb, but i coud be mistaken, i can fire it up and verify if needed) I have not used it much. Prom battery is dead, i used to jump it

SGI Indigo, WTB Power supply? Burning smell?

Okay, after a ton of rounding up the parts I finally have the keyboard, keyboard cable, mouse, Indigo and 13W3 to VGA cable to try to bring my Indigo back up. I put my baby on the desk, cable it all up... and burning smell when I start it up. So far I can't find anything on the PCBs that

Some time ago there was a discussion about the elusive 98228A ROM that supports both the 9885 and 9895 diskette drive units on a 9825T, well good news! A fellow MoHPC member David Ramsey very kindly loaned me his, and with a little careful reading of the service manual along with studying

So, does anyone know of any documentation (especially engineering drawings) for the M8728, which is the 256KB board for the MK11 (originally), also later useable in the VAX-11/750 and VAX-11/730? The M8728 and M8750 are in fact the same PCB, with different DRAMs (16K or 64K) and different jumper
