I have a good AS-2518-35 board that boots fine with Playboy 9316a roms for U1, U2 and U6. Am trying to configure it to run Stern Flight 2000 game with 2732 eproms.
Flight 2000 says it uses U1, U2, U5 and U6, all 2716. I combined U1 and U2 with command “copy /b U1.716+u2.716 u2.732” and U5 and U6 with the command “copy /b u5.716+u6.716 u6.732”
Changed jumpers on board according to information found on Pinwiki. E4-E13a, E7-E8, E10-E11, E12-GND, E16a-E-29, E31-E32, E33-E35.
Board does not boot. I get the flicker, 1st flash, 2nd flash but no 3rd flash.
Burned EPROMs for SpeakEasy which uses 2732 (no combining needed) U2 and U6 only. Per text file jumpers are the same as above except E12 goes to E9 instead of GND. Board boots fine.
Am I combining files wrong or are the jumpers wrong? Using the same 5101 in all tests so it is good but not getting the third flash says it is bad. I don’t much activity on address lines when it is hung up so I am thinking it is software going off the rails and not a hardware problem since the board works with other eproms.
I did try the Flight 2000 2732 eproms with the SpeakEasy jumper configuration, same problem, hung after 2nd flash.
Any ideas on things I can try?
