Sorry for the delay... I can confirm that pressing "0" during the
"splash screen" of the Transwarp initiates a self-test on a v1.3 ROM
The "1" however does nothing...
Hello and thanks to all who answered!
I received a 1.4 ROM file from David and put it to use, now "0" and "1"
both work. (Though I ask myself why in the world did AE use windowless
EPROMs that can't be erased?)
Because they're cheaper. ;-) Strictly, they are not EPROMs, but PROMs.
The other problems remain. I found that the problem with the CF not
booting goes away if I don't cycle the power too fast, I assume there's
some memory content that survives otherwise and causes problems.
I've not yet been able to get Ultima V to work correctly with the card,
so I guess I'll try exchanging some RAMs. How fast do they have to be?
Look at the number(s) after the dash and you'll find the speed.
If the power supply (original Apple) is marginal, would replacing the
electrolytics inside it help? Or is it always going to be marginal with
a Transwarp card in the game?
It wouldn't surprise me. The Transwarp completely ignores Apple's
guidelines about power consumption for cards.
What about putting in extra thick power wires to slots 3 and 6 to remove
load from the PCB traces, like other people have done on the IIgs? Would
that help in a IIe?
It will help, but only very slightly. If I did that and it "fixed"
something, I'd be worried about running a very "marginal" system.
So many questions, I fear I'm beginning to annoy you all.
Never! ;-)
