Title: GVP A2000-030 COMBO owners I need your help!
Post by: Hanzu on June 03, 2016, 12:12:08 AM
Looking for anyone who can read the contents of GVP A2000-030 COMBO card PAL chips:

I will pay for the good read . jed file of:

U34/7387 (usually PAL20L8 or TIBPAL20L8 chip).
or
U38/38CC (usually PAL16L8 or TIBPAL18L8 chip).

Also may buy working chips if someone has spares for sale for these cards.

Feel free to offer complete working or faulty GVP A2000-030 COMBO card too just in case I get desperate enough.

I only need those to repair my card. I'm not going to try to manufacture or reverse-engineer anything related to this card. :)

I can paypal you good money for a good read .jed file with a checksum that matches the one printed above the chip (I can check this, if you are unsure how to do that). Please contact me for this at hanzux@gmail.com or reply this post.

Those pals will be protected and no simple way to read them out in most cases.
i think a good few of these cards have popped up on US ebay though.

I know something about this Project history and seems that GVP pal chips are randomly protected. ie If your card has those protected, others may have other pal chips protected.

Yes.

So far those 8 PAL chips (DIP cased ones) have been read from 3 different cards.

My card had 4 non protected and 4 protected.
The second card had 1 non protected and 7 protected.
The third card had 7 non protected and 1 protected.

Were you able to get hold of all the PAL .jed-files you needed? I got a rev3 25MHz version of this card and a HI-LO ALL-03 which I think should be able to read any non-protected PALs.

I dumped loads of info about my card in this thread (http://www.amibay.com/showthread.php?39248-GVP-A2000-030-SCSI-controller-CPU-load-issue) (including picture and PAL chip numbers), if you are interested.
