Re: How can I tell what I've got in a TransWarp GS?

["Scott V. McGuire" <fake@f.a.k.e.net>]

Thanks everyone.  The cpu is unmarked for speed, the oscillator says
35 MHz and Control Panel reports ROM 1.5, so it looks like I have a 6
or 6.25 MHz cpu with 8k cache.

I think I want to try the upgrades.  I've seen the SHH page before but
have not been sure whether the cache card is still for sale or if the
page was just for nostalgia.  Are they?  Also, does anyone know how many
65c816s you get for the $100 minimum order from WDC?  I'm thinking to order
them and sell off the extras on ebay.

Oh, and any good source for oscillators?

Cheers,
-Scott
