>Also, which way do the ROMs swap for those later boards (i.e where should
>035145 go for -01..-04 as opposed to -05 and -06?
For revision 4 (and earlier) boards the program ROM socket locations are as
follows:
035143 ..... C1
035144 ..... D/E1
035145 ..... F1
For revision 5 boards and above, 035143 and 035145 are swapped (035144
stays in the same place, ie in the middle).
So the ordering is as follows:
035145 .....E/F2
035144 ..... H2
035143 ..... J2
Sheet 1, Side B of the Asteroids schematics that I've downloaded from the
'net lists all these, BUT ....... it gets the locations of the program ROMs
of the rev 5 (and later boards) wrong!
