Group,
2nd problem found with Mini Buffered Prototyping board. or Sea of PTH. The 74LS245 pins labeled pWAIT and pINTE are reversed. I even remember laying those tracks, wondering why it got so "easy" all of a sudden and I didn't need to swap the traces. I checked all the other pins and they go to the correct S-100 pin as per the printed labels. Regards, Josh Bensadon |
