- Well, I was at the atari messe in dusseldorf... ...and spoke to
- the designer of this accelerator... what happens is that the chip is clocked
- at 60 mhz, but the card was running at 33 mhz, and he claimed that next does
- something simmilar, hence, they are both the same speed...
-
- by the way, the instructions on how rto make the expansion, will be
- published in a magazine(german), in the near future.

- Bye, B.S.
