Well, best I update this request.
No longer after any Sparc or SGI gear (well, except for an IndyCam or two) as the collection now holds a SparcStation 10, SparcStationLX, SGI Indy and Indigo².
DS10/20s have all gone too. Strangely, no extra space in the garage though.
Now all I want to round out my collection is a DSE Super-80
- but I'll settle for a remake if the board tracing gets done.
