Phoenyx,
	I've never known you to give up so easily.  Here are two leads from my
previous postings.  Shouldn't there be something buried in the old CSA2

Right.  You need something like the Transwarp IIe or the
TransWarp II or TransWarp III cards.  Then you'd need to
overclock those cards with new oscillators.  Maybe you'd
need faster RAM on the accelerators too.

The exception is the IIc Plus.  Because the IIc Plus has
a separate oscillator just for the CPU separate from the
oscillator that provides timing to the rest of the IIc Plus
motherboard, you can accelerate it just by dropping in
the 14Mhz unit and changing the oscillator that clocks the
CPU.

Though few users have done it, some have posted remarkable successes.

The Transwarp IIe is pretty easy to accelerate.  You'll need a 14Mhz 65C02
available from Western Design Center.  You'll need a faster oscillator, 4x
the speed you want the CPU to run.  The hardest part of the upgrade is to
replace all the RAM chips with faster ones.  I think the Transwarp IIe uses
regular RAM, not SRAM, which is harder to find at faster speeds, but the
speed of these has improved drastically, so such an upgrade should not
be that hard.

Are the RAM chips on the Transwarp IIe socketed or soldered?  If they are
soldered, you need to be comfortable with soldering and desodering to
replace them and upgrade your Transwarp IIe.
