Ah yes, but this is a rev.B, capable of handling 128MB. :)

Aaahh.. well this looks more and more like a screwy Centram then.

Umm.. but it already was called mintnp! :)

..ALL of it? :)

Naturally. :) They also blame Cubase Audio and HDDriver for any problem
I have. Pretty strange for an accelerator that's supposed to be
compatible with MiNT, Cubase Audio and HDDriver... ;-)

Heheh yeah.. the CenturboII has no problems at all, it's just that all
software is so bad you can't use it. Well, they better live up to their
compatibility claims or I'll set the Dutch consumentenbond on them and
will be asking for my money back. (And I don't mean the mem protection,
but my buserror-problem which they also blame on MiNT). :)

Dissections can be nasty.. I expect tos 7 is no exception..;-)
