The ROM only checks for CAFE not the COCA...

@alenppc can you check address $B80000 on the ReV0 please with DiagROM?

Sure, but I don't know if I can get round to it before this weekend.

No worries. I suspect we will see C0C0CAFE for a rev0.

I’ll maybe slap together a tool to check.

Currently checking all CD32s that I currently have access to [4] for the revision 0 chip. I have a CD32 diagrom sitting here should I stumble across one.

Will update later on.

Here is a program i knocked up to check Akiko revision.

https://github.com/terriblefire/terribl ... takiko.zip

Its in ADF and Exec form. Simply run the testakiko binary in AmigaOS (no WB needs loaded)

All four are revision A here unfortunately/fortunately.

I just bast...ized Akira`s systest iso and put testakiko on it, tested and it works.

Just unzip the attatched file burn the iso, then cd at the prompt it will show CDTV_test dir, then just type testakiko hit Return and it will show what version you have

Unfortunately the result is the same on the Rev 0, still reads it as 0xC0CA

Hopefully Steve will find what register the Rev 0 is stored in when he gets that Mobo and can then ammend his test software

Very odd that CBM didnt have a different verison for the chip. They were usually good at this sort of thing.

Consoldering the CD32 was hastily built as a company saviour they probably didn’t do the usual diligence. Maybe it’s not possible to detect different revisions via software.
