Took the logic board out.. it looks quite clean as far as my untrained eye can tell... took out the battery had what appears to be a date on it GL/24/88 ... so its a miracle it hadn't leaked in the slightest. It boots up still... still no SCSI. Restarted it and it booted up fine to a couple different floppies still. So I haven't damaged it further at least

I did take the ROM out... it looks like its at stock SE/30 ROM. It looks like a have 4x 1Mb ram simms and 4 256k as that is the only combination which would add up to 5Mb right?
