I have a 4D/70GT with no system software... While I'm here, I thought I'd look into the feasibility of porting Linux to this machine. [In fact, I'm probably not going to have access to the machine for long enough to work on it, but maybe somebody else will. (the machine belongs to the Computer Preservation Society here in Cambridge...)] Anyway, points that spring to mind: * the CPU is an R2000; I don't think any of the current ports are for less than an R3000 -- does anybody know how different the R2000 is? * without hardware documentation I suspect it will be impossible to get anywhere. Every board seems to have a CPU on it :-> The ESDI and ethernet boards both have 68000s, and the graphics board set has a 68020 complete with debugging monitor you can access via a serial terminal, in addition to all those custom chips... Are SGI being helpful about providing documentation on the older hardware? Peter Maydell
