PCB label 510-1129A01
PCB has edge connector for module, but no external slot
There's room for 2 SIMMs at U22 and U23. Unpopulated in Excel 68000, used for
128KB hashtable RAM in Mach II. Mach III has wire mods to U8/U9(2*8KB + 2*32KB piggybacked).
There's room for 2 SIMMs at U22 and U23, unpopulated in Excel 68000 and Mach III.
Mach II has 2*64KB DRAM with a MB1422A DRAM controller @ 25MHz.
Mach III has wire mods from U22/U23 to U8/U9(2*8KB + 2*32KB piggybacked).
Mach IV has 2*256KB DRAM, and a daughterboard(510.1123B01) for the 68020.
I/O is via TTL, overall very similar to EAG.
