I've had a DECSystem 5000/240 for a while and recently decided to check it out. I cleaned it up and tested the PSU offline and it appears OK. I connected the PSU to the system board via the large ground and +5V cables only and no issues, PSU fans turn and some LED's are active. I switched it off and then connected the 12V connector to the system board and after powering back on I got a little flash from by the 12V connector and no fans or LED's. Quickly powered it off and checked around the area by the 12V connector and low and behold I had a short circuit surface mount diode, I photographed and removed it (photos to follow). Oddly when I now plug the 12V connector in I get output on my VT terminal and the self test apart from NVRAM battery all pass. It has 64MB RAM and 1MB NVRAM. The DECSystem has no Turbochannel graphics unlike the DECStation. I plugged an expansion box into the SCSI port and the devices are seen but this expansion box was from a VAX/MicroVAX so I'll have to add a HDD. I have a DEC RRD CD-ROM for the expansion box. I've looked on this forum and Google for Ultrix images to burn to CD (if they existed, tape seems common but I suspect that may be for the MicroVAX Ultrix??) but none of the links or .img downloads seem to work. Does anyone have any pointers to working downloadable images? TIA.
