Transwarp IIe revisited

[Linards Ticmanis <ticmanis@gmx.de>]

Hello,

just managed to get hold of a Transwarp IIe accelerator. Note, not a TWGS.

I'm running it in slot 3 of an enhanced IIe. Luckily there was enough
info to be found on the DIP switches. But some questions remain.


0.) I have a bootable CFFA in slot 7 with ProDOS 2.0.3 on it. Sometimes
on power up, after the TRANSWARP logo, the CFFA will boot, and sometimes
it won't (naked Applesoft prompt appears below "Apple //e"). In the
latter case, PR#7 will put garbage on the screen, while
Ctrl+OpenApple+Reset will usually correctly boot the CFFA. Is this
normal? I tried removing all other cards but it didn't help. Flipping
the DIP switch on the Transwarp to access Slot 7 with 1 MHz didn't
change this.


1.) An posting in here from 1996, by Tom Zuchowski, said: "To completely
disable the TW, hold down ESC during power up.  Holding down "0" will
activate the TW self-test.  "1" will bypass the startup logo."

However of these only ESC seems to work. "0" and "1" do nothing. Is this
normal?


2.) My card has a v1.3 ROM. It seems clear that at least a v1.4 ROM
exists and is or was sold by GSE. What are the advantages of the 1.4 ROM
(or any later if it exists)?


3.)Since I have access to an EPROM burner and thus it doesn't make too
much sense to ship around chips, is a v1.4 (or later) ROM available as a
binary file to be burned, either for purchase or for free?


4.) I tried playing "Ultima V" (from floppy) on the machine which
supposedly supports the Transwarp. Flipping the system speed with Ctrl-T
in the game works as described. But the game has a high tendency to
crash (the machine just resets like CTRL+OA+RESET), mostly during disk
access. Is this normal? Again I removed all cards except the Transwarp
and one 5.25 controller, didn't help.


Thanks for any answers,
