repinning our “sparcstation ipc” psu to now be a “alphastation 500/266” psu for the low low cost of four staples (molex hates her!)

Currently on my workbench - another fried Sun SPARCStation IPC PSU.
What have you been thinking when producing these "cardboard PCBs", Sony?!?

After successfully repairing the SPARCstation 4, boot Solaris 8 from cdrom. I still have to fix the NVRAM.

Ran across this going through my old stuff. The pre-pre-pre-release docs for the SPARCstation-2 (Calvin). Was given to us lowly techs who were destined to debug them coming off the manufacturing line. When I started at Sun, I was a lowly failure analysis technician, the good jobs went to Stanford grads, DeVRY grads needed to come in through the back door. Eventually made my way into engineering and then SunLabs (where the real party was).

List of features to be found on the SPARCstation2 motherboard during pre-release. 40MHz clock and a whopping 64MBytes max on the board! Good times!
A couple of schematic pages from the SPARCstation2 while still under development. Legend says "P0" which was usually very early in the development status.
SPARCstation2 Hardware overview page showing some timing diagrams for the reset timing along with a block diagram of the main board.

@Iggi1968 The Sun Voyager took on a second life as a tablet computer prototype. A different team (in Sun Labs) took the design and mangled it into a tablet prototype.We called it R.O.V.E.R meaning Remote Operation of Vast Electronic Resources. Mosaic Browser was just about to come out and the pairing was obvious once we saw it. It was heavy, but ran an optimized version of SunOS and had a tethered pen input. Photos have more description.

An enclosed Sun R.O.V.E.R prototype. A heavy but handheld tablet developed at Sun Microsystems around 1992.
Side view of the internals for the Sun R.O.V.E.R prototype. Essentially the guts of a SPARCstation Voyager, compressed into a tablet with the weight of a dying star. A SBus expansion slot can be seen poking out from the main board. Touch screen controller board can be seen in the lower left of the photo. Upper left is the heat sink on a DC-DC controller. Center is part of the metal frame that holds the same changeable AC/DC power supply(or battery) as the Sun Voyager. Bottom is the LCD display, same as what is found in a Sun Voyager.
Rear view of the internals for the Sun R.O.V.E.R prototype. Essentially the guts of a SPARCstation Voyager, compressed into a tablet with the weight of a dying star. A SBus expansion slot can be seen poking out from the main board (top). Touch screen controller board can be seen in the lower right of the photo. Lower left is the heat sink on a DC-DC controller. Center is part of the internal metal frame that holds the same changeable AC/DC power supply(or battery) as the Sun Voyager. Face down is the LCD display, same as what is found in a Sun Voyager.

The lights of a @BlueSCSI hanging out inside a Sun .

Now that the house is a bit less full again, let’s see if we can get this puppy working properly!
