I mentioned a while back that I'd begun work on restoring my newly acquired Indigo2 IMPACT R10000 system; way back in April I'd picked up a Maximum IMPACT boardset from Pastech, 3.5" & 5.25" drive sleds and a 32x internal CD-ROM from Used Tech Dot Org (formally Aftermath Technologies), a 195MHz R10000 CPU from Reputable Systems and a 100Mbit 3Com EISA 3c597 card (essentially a Phobos E100) purchased from an individual seller. The system has languished since then; the current system drive is too small to do much with (6GB) and my attempts to locate the TRAM option to fully expand the Maximum IMPACT have met with absolutely no success despite a couple postings to comp.sys.sgi.marketplace pleading for help.
The system will once again be receiving some attention; I've just arranged to purchase a Video for IMPACT boardset (essentially Galileo (ev1) for IMPACT systems) and will be picking up at least one ACARD ARS-2000FU Ultra SCSI-IDE bridge to utilize low cost high capacity IDE drives as I happen to have two 60 GB drives I'm not using for anything else at the moment.
The ARS-2000FU is a small tray like device that attaches to the underside of a 3.5" IDE drive, transforming it into a SCSI unit which will still fit the drive sleds of SCSI based machines like the Indigo2. After searching online, I discovered Microland USA resells these units for $80.00 each.
I should mention that these upgrades have freed up a couple of components if anyone is interested, namely a Solid IMPACT board (SGI PN 030-0786-002; would be great as a second head if you have a 060-0027-xxx power supply) and a 175MHz R10000 CPU module (SGI PN 030-1433-002).
