I have a card that looks exactly like this and that one is 3.3V so i needed to mod it with a voltage regulator to get it working with my mediators.
I have the old mediator pci 1200 and 4000D and they do not have 3.3V so i needed to mod my card but doesn't the 1200tx have 3.3V if you feed it with an ATX supply?
If that is correct it should just work for you.

hi, im using a 750w atx power supply, the power supply i received with my tower unit only does 220v. so i scrapped that cheesy piece of crap.
so the tx versions support both voltages?
any card mod i need to do?
thanks

well with some tinkering i have more life into the system..
found out that you cannot have it on 0mb mem space jumper

i now have it on 8mb..
config..
wait..
jumpers are installed.
also have the following lines in my startup-sequence, first is pretty much at the beginning of the file
C:ACAClock S=3 QUIET

and then almost at the bottom i have it bumped back up
C:ACAClock S=4 QUIET

i can now change settings in the pacasso96.  im getting wierd screens, but i think that is my timings and such.
luckily i have an indivision mk2 on my screen so its not bad to look at on the normal output.  but still would like to get the gfx card going.

will update more as i config.

@ bomrat
been many years since I set up my Radeon9250, 256MB, 5v board ion my 1200T but remember it sure as hell took me a while to battle with mediator and Picasso96 lol I do recall I tried everything 3 x over and then gave up and after a few weeks break turned my1200T back on and somehow it mysteriously worked...only AMIGA ;D ... good luck & keep us posted
