DECpc AXP 150 (JENSEN)

I actually have two of these units, both sadly have suffered from being stored in damp conditions and the one that was supposed to be fully working was completely dead. The picture is of the originally stripped for parts unit that I managed to get to at least POST, and at one point boot into the Windows NT 4.0 setup. The machine errors with a double machine check and won’t boot fully. First I replaced the RAM on the original motherboard from this unit and it looked promising, but after a power cycle I was back to similar machine check errors from before. I then managed to find a replacement motherboard but that sadly didn’t improve my situation either. I’m not sure if there is a RAM fault or whether the original board damaged the replacement RAM I got for the machine. I hope to get a working unit someday, whether that is a replacement machine entirely or parts to combine with what I have to make a working one.
