Processor PCB, A006020-xx

Processor PCBs
(01 through 05) are all physically shorter than the (06 through 18) versions.

(06 through 18) PCBs are longer so that eight chips of program memory
(Proms E1 through E8) could be replaced with two chips (Roms E00 and E0).

Therefore, you cannot use ROM program memory chips E0 and E00  in the
(01 through 05) Processor PCBs.

The (06 through 18) PCBs can be converted to  2716 EPROM's with modifications to
the circuit traces around the E0 and E00 Sockets
