Happy New Year everyone!
I was wondering if anyone happens to have any documentation or information
about the 8219HP adapter by IO Corporation? It is a protocol converter from
Twinax to RS232 emulating an IBM 5219 printer. I am mostly looking for
information about the option/rate switches on the back.
I acquired one of these for cheap recently but haven't been able to find
any information about it.
Thanks!
Does anyone here have a running Axil 220 or 245 (Sun SPARCstation LX clone)? My 220 has a dead PSU and I am trying to get it working with a modern PC PSU. But I don’t know the pinout for the power connector.
While the power connector is the same as used by Sun, the pinout and, aside from +5V and GND, the wire color scheme are different. I have identified 3 of the 6 wire colors and 7 of the 10 pins. The wire color scheme seemed to be a match for early sun4c but I just found something that suggests a couple wire colors are used differently.
I have found that black is ground, red is +5V, and yellow is +12V. White, orange, and blue are TBD. A marking on the PSU board suggests white is -12V. Blue and orange seem to only used by a daughter board centered on a LM339 chip. But, as a software guy, I can’t tell what it does.
Anyone here have any insight here that might help me?
