Description
ATARI 800XL 27C64 / 27C128 ROM adapter for the original 2364
ATARI 800XL 27c64 / 27c128 ROM adapter
BASIC ROM
It adapts 27c64 / 27c128 to C060302A (U4).
27c128 requires a 4.7K pull-up resistor and a jumper (normally closed).
27c64 does not require the resistor and jumper.
OS ROM
CO61598B (U5) can be replaced with 27c128 w/o the adapter.
