[comp.sys.apple] Patches to use TRANSWARP's 256K as RAM: A Bad idea?

halp@TCGOULD.TN.CORNELL.EDU ("Bruce P. Halpern") (05/05/88)

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.

by the way: 
when i run this proline software i have the hell of a problem on my //e.
when the prgm tries to slow the thing down i get two ugly inverse '!'s
on the screen...
it seems that some other cards interfere with the transwarp (at least in
my stuffed apple) : only after taking the mouse & thunderclock card out
the thing would reboot correctly after i did poke 49268,3 to shut it off.
otherwise those '!' plus hang occurs....
anyone encountered similar things ?

RE: Interference between Transwarp and other cards.

In one //e I have Transwarp, RamWorks III with 3Mb, Apple Mouse Card, Super
Serial Card, Unidisk 3.5 Controller, Buffered Grappler+ parallel card, Apple
Disk II controller, Apple numeric keypad controller, with original Apple 
power supply and no fan. All work fine, with no conflicts. AppleWorks (with
Timeout enhancements), Pascal, Softerm 2, ProSEL, BASIC, are used. Another
//e has similar array with Applied Engineering Timemaster II H.O. clock.
