Silicon Graphics Indy R4600SC Model CMNB006Y66

This is a Indy with the 24bit graphics option manufactured in 1996. It arrived to me with a 2GB SCSI disk and 64MB of RAM. After trying to upgrade the RAM to 256MB I ended up swapping in 128MB of RAM from the Indigo2 I acquired later. I also put a larger/quieter disk into the machine.

This machine has been slightly problematic – some sort of noise couples into the speaker (which is located in the power supply) during operation, the video output is fairly noisy and the motherboard doesn’t operate properly with 256MB RAM installed (the maximum). I may swap some parts around to see if I can bring this to a better level of functionality. The Sony PSU that was shipped with this machine is better than the earlier Nidec units, but I still suspected that the power supply could be causing the noise issues. I recapped the PSU with new high-quality electrolytics on 6 MAY 2017, but the problem persists.

hinv, uname, etc. report the Indy board as an IP22 for whatever reason, but the silkscreen on the motherboard says IP24.
