Tube❄Timetime to upgrade the video card in my Sun SPARCstation 1+.
looks like the people who designed it left their names on the circuit board. i guess some of them are crossed out because they left the team?
hmm, maybe my adapter board (configured for H/V sync) will not work with this card that puts out CSYNC only.
no CSYNC comes out. checked it with a scope. OK, maybe the monitor sense pins being floating is a problem? i think it should still come up even with nothing (1152x900 66Hz).
could be an old PROM version. the previous screen shows ROM Rev 1.1, but here it looks like I need PROM 2.0 or higher.
PROM is 525-1043-07, which is for a SPARCstation 1, not a 1+. uhh, looks like i actually own a SPARCstation 1 but the lid has the wrong logo on it!
looks like The Retro Web has a PROM image i can use.

slash@tubetime Ah, I remember RARP fondly for all our diskless Vaxen (1100's IIRC). I enjoyed programming the 3-Com eeproms. I eventually gained a reputation for debugging boot, so I spent quality time with tcpdump. We had a $10,000 HP "Internet Advisor", but tcpdump was built right in as part of TGV Multinet.
This was also good for the wallet, since these were critical path to the product, and the stoppage got visibility, as did my skill at RARP. So I got raises from that.
