Post by Steve PiettePost by Steve PietteAnyone have the 1.X.X version of the Sun2 boot PROMs that came out
with/after 4.0? I have the Rev N and Rev R PROMs.
Just tonight I came into possession of a basket case 2/120 as a disassembled
pile of parts. I have two CPU boards. Thanks to the help of a few friends, one
has been identified as Rev N, and the other as Rev 1.0f. They are imaged
<https://diskfutility.com/files/sun/rom/Sun2-120-rev1.0f-IC1.BIN>
<https://diskfutility.com/files/sun/rom/Sun2-120-rev1.0f-IC2.BIN>
The rev N images look like the standard version for the Sun-2 keyboard
but the rev 1.0f look like it may be a winner. I'll try burning a
couple of 27256 EPROMs and see if it boots up and what it says it is.
It took a little longer to get the EPROM burner working than I planned
but it's done, burned the 1.0f images to 27C256, moved J400 from 1-2 to
2-3 for the 256 chips. Here's the result using a Sun-2 Prime CPU board
that was running Rev R before the swap:

While there may still be a later (newer) revision, this works great.
Thank you Ryan!
