is it possible to get like a Rom socket adapter thats prejumped/wired to fit in over it to go w/ a KS 3.1 Rom? or should i keep mine @ 1.2?
An original 3.1 ROM from the 1990's will work with just a jumper between pin 1 & 31. This would be my recommendation, but cost may be an issue.
eproms need more work.
1. Bend up pin 31, solder it to pin 21 to keep it in word mode.
then to get A17 on pin 1 either
2a. build a tower with two rows of pin headers and solder a wire from pin 1 of the rom to the empty hole of pin 31. This has the disadvantage of making the rom higher, which can cause a problem for some expansions.
or
2b. solder a wire from pin1 to pin 46 of the 68000.
I wouldn't hack a revision 5 motherboard. I think the ACA500 would allow you to run kickstart 3.1 without even opening the case.
