The Sun Sparcstation 10MP is fun a computer to use. My restoration is ongoing. It has some issues that I continue to explore. I haven’t started documenting it because it has occasional boot issues and complains that it motherboard needs to be replaced, although it seems to work fine (usually)

The Silicon Graphics R4000 is my favorite computer in the collection. It’s very nice to use (still today) and the Elan graphics package looks fantastic. I’m hoping to finish documenting this restoration that I did concurrently with the R3000 restoration soon.

Since I started collecting and restoring various older computers, I really wanted an Indigo. This R3000 was my first acquisition and it’s been a handful. I plan to dig in a work on the long story soon.

In January 1987 came the final revision of the Apple IIe, often referred to as the Platinum IIe, due to the color change of its case to the light-grey color scheme that Apple dubbed "Platinum".
