Commodore A3200/A3400 prototype CPU board.

Hi!

This card was found in a A4000D/40. I was suprised to see there was no 040 in there, but even more suprised when I turned the board over and saw the 020 and the extra chips.

I found the board on BBOAH in the mystery corner:

My board is exactly the same. It even has the same handwriting on the chip and is written by the same person. The only difference is that my boards serialnumber ends with 58. I have tested the board in my A4000 and the 030 is fully working (I can not test the 020 in A4000. Only in A3400/A3200.)

I think there's a missing PLD (location normally unpopulated) on the A4000 mobo that is needed for it to work with the 020. It's just to the right of the front panel led headers.

You can send the card to me, I can test the 020 in my hardware. :mrgreen:

If I´m not misstaken it's the U860 and U152 that are missing on a A4000 mobo that are needed to use the 020. There is even a jumper J850 named "68020" just above the U860.

Thank you for your offer! But I wouldn't want to risk this beauty getting lost in the mail

I've got the same card, but an earlier serial number (10).

Cool! Any idea how these cards ended up where they are today? Where there 3200 prototypes sent out by Commodore?

I also have one, I need to check the serial number.
And also need to test it in my A3400
