Thanks P-Man. I'll update the article to state that this is now confirmed by two sources and is a definite no-no.

thanks for the input,

I didn't know that!

I can also confirm that if you can find a USB adapter with a Prolific PL2303 driver chip in it then you can use the Data I/O on a Mac via VMWare Fusion. It's a bit picky about the virtual ports since VMWare in their infinite wisdom assign some virtual printer port to LPT1 automagically and just can't comprehend software that would be so picky as to HAVE to have either LPT1 or LPT2. It certainly can be done though.

I have the Mac driver package in my downloads folder if anyone would like it uploading somewhere?

Also, it is perfectly possible to use the Data I/O natively from a Mac (yes, really!) but clearly it's very painful without a GUI. Something I did start working on some years ago but never bothered to take very far. Firstly because it worked ok in a VM and secondly because most of the other tools were Windows only so it seemed kind of a futile exercise.

I went to use my Data I/O 29b with unipak 2b on Tuesday and spent hours pulling my hair out programming some eproms up, and verifying them several times but wasn't getting any luck with decent sigs in the UUT. My data i/o has developed an issue 'loading ram from file' hence it will program and verify just fine, but when i read back the programmed roms on my Galep-3, i found they were just garbage. I hope its not a permanent error...
