Ultra 1
Overview
I have two Sun Ultra 1s. Both of these systems came out of a basement and have a decent amount of rust on the chassis. Unfortunately, one of the systems never worked correctly. It would display MMU error while running self tests. I was able to find a replacement motherboard for a good price on ebay, so now both of the systems work.
The first unit has a 143MHz UltraSPARC with 256MB of RAM running Solaris 8 and OpenBSD 6.9. The other with the replacement motherboard has a 167 MHz UltraSPARC with 192MB of RAM running Solaris 8. All three hard disks are 15k 36GB Ultra320 SCSI disks.
Drive Sleds
I only had 1 drive sled, so I designed and printed replacement rails. The design is uploaded to Thingiverse. Drive Sled
