Icky, can't definitely locate r3 on the silk screen? I there a pic or schematic available to help locate this 10k puppy?

Thanks Paul

Thank You..

One 84 pin socket arrived in the post today, thank you Mr Exxos.

Now to see if I can sneak out and solder it in.

Ok, the good news we finished building the board and I'm going to attempt to boot from it. Bad news is thought I had a slug of sn74ls245's but to know can't find them. ;) However I believe they are for the IDE so I'm attempting to boot using the eprom put in this board. I would be nice to have a designation for the jumpers.. I'm assuming only one applies for the rom is which half were using. I'm going to attempt to use the one from the mega so half won't work because it currently contain 1.04 and the diadROM.

Its labelled up "TOS SEL" on the PCB ? That is the only jumper on the board.

Looks like it was designed for the mega.. perfect fit. I assume it matters which half of the rom 2.06 goes in. If so high or low?

It doesn't matter.
