Processor PCB, A006020-xx There are eighteen variations of the Processor PCB. Each Processor PCB is marked with a part number next to IC location F1. Part number (A006020-) is permanently etched onto the PCB. The dash number variation is added with a felt-tipped pen. The PCB serial number and the game name are also marked in felt-tipped pen somewhere between locations A12 through A20 and B12 through B20. All variations for the five games are listed as follows: Processor PCB Identification and Size *** Short Boards *** A006020-01 The Atarians Standard Proms (E1-E8) A006020-02 Universal --------------------------------- A006020-03 Time 2000 Standard Proms (E1-E8) A006020-04 Airborne Avenger Standard Proms (E1-E8) A006020-05 The Atarians Standard Proms (E1-E8) *** Longer Boards *** A006020-06 Time 2000 -------------------------------- A006020-07 Time 2000 Linear ROMs (E0-E00) A006020-08 Airborne Avenger Linear Proms (E1-E8) A006020-09 Airborne Avenger Linear ROMs (E0-E00) A006020-10 Time 2000 A006020-11 Middle Earth Standard Proms (E1-E8) A006020-12 Universal Linear Proms (E1-E8) A006020-13 ---------------- A006020-14 Middle Earth German Proms (E1-E8) A006020-15 Middle Earth Linear ROMs (E0-E00) A006020-16 Middle Earth Linear Proms (E1-E8) A006020-17 Space Rider Linear ROMs (E0-E00) A006020-18 Space Rider Standard Proms (E1-E8) Processor PCBs shape: 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 EI 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. Upgrade : The 06 through 18 PCBs can be converted to 2716 EPROM's with modifications to the circuit traces around the E0 and E00 Sockets |
