Subject: Patches to use TRANSWARP's 256K as RAM: A Bad idea?

TRANSWARP (Applied Engineering's 3.6 MHz accelerator card for Apple II) uses
its 256K of RAM to hold the entire contents of the Apple ROM, since otherwise
things would have to slow down to 1 MHz every time ROM was used. It uses 


the rest of its RAM to "emulate most of Apple's [builtin] main and auxilliary
memory" (TRANSWARP manual). This means, for example, that a TRANSWARP in slot
0 of an Apple II or II+ would eliminate the need for a language card.

I think that patches would be a bad idea because you would probably loose much
of the acceleration in order to gain a little RAM. It would be better to get
a separate RAM card (AE's RamWorks is very nice).

TRANSWARP can be used on the Apple II, II+, and IIe, in any slot (including 
slot 3 in a IIe). It can not be used in a IIgs.
