Great stuff Marco - thanks!!

I have seen a few of these MPU3 test units before, but do you have a picture for an MPU4 test unit as I have never seen one of those.

Hi Superbank:

Sorry, but i have looked at my Computer. I got no mpu4 Testboard-Pictures. But on middle-September i'm on holidays, and then i think, i visit my Friend who had the official Barcrest-Distribution in Swiss. Perhaps i shot some pictures then...

Many greetings
Marco

Hi everybody!

I've just got my hands on a MPU4 Test jig, but the problem is that I don't have the program card for it. (I would assume it uses one)

Does anyone have any suggestions to what I could do???
Is it possible to get the software from somewhere and just change the eprom on a regular game/program card?

Sorry to bump an old thread, but I'm trying to get my Mpu4 rig up and running

here are the test rig mpu4 roms.

Those prom file's don't look quite right, one's 8k and the other is 16k

Haven't tried them yet but surely it's not right?

Any of you super guru's out there be able to shed any light on the subject ?

Doh!

the test rig uses a single prom I take it,
and you supplied one for a 64k chip and one for a 128k chip.

Cheers again, been looking everywhere for these.
