- I forgot to ask if anybody knows if the MegaChip 2000 works in the Rev6.4
- Amiga 2000's. If the newer version works (with the 8375, see ad in
- AmigaWorld) could I just use the 8375 that's in the machine already?
- Also, does the 8375 have the inputs XClk and XClk_en as the 8372A or
- are these gone (different use) as in case of the 8372B. Since only
- one pin more is needed could it be that the PAL/NTSC input is used
- as A20 (address line) in case of the 8375? This would make it more
- or less pin-compatible with the 8372A since it doesn't require the
- external multiplexer and the previous PAL/NTSC input (A20?) could be
- GNDed (RAS_1 becomes DRA9 but that shouldn't cause any problems).
