- I am at work and don't have the part numbers with me - will post them
- on the morrow though. I believe that they are static column zips,
- but I will check to be sure.

-
- I had 4 MB of fast and 2 MB of chip (err the 2 mb is the "video").
- There were 8 chips total, and I am adding 8 chips.

- I am not sure if this is what you want but :
- A3000UX 100 MB hard drive, 25 MHz, 4 MB fast, 2 MB chip.
- Just had the ROM upgraded to 2.04 (got the last ROM tower in the US!)
- Will post the chip numbers off of the new 4 MB tomorrow ( or later
- tonight if I get ambitious enough to remove the new RAM so that
- my machine will boot ). I do remember that the new chips are
- Toshiba 70 ns and the original chips are NEC 80 ns...

- One more data point, I am able to get the new chips to work alone as
- the only 4 MB so I am certain that they are not bad. I have also tried
- one of the new chips with 7 of the old (with the new chip in the first
- position) and the machine booted with every one of the new chips replacing
- the first chip. So I am not sure how they could be incompatible.
- (Did that make sense?).
