Thanks guys!
I didn't get any notifications of your responses, I looked for the email notifications, but I couldn't find them. Ah, now I see it, I needed to check it in the full editor.
Concerning the trainer, I took it to Phreaknic in Murfreesboro last weekend and opened it up and ohmed it out a bit. I found that the 15 pin connectors connected to the power pins on the board, but that was about it (I don't have cables made up yet for the power cable to the boards).
The traces on the boards are hidden by a black mask. Thanks Lab Volt...
I have to find my EEPROM programmer first, and then I can upload the program.
If you look at the Advanced Digital Logic Trainer, you will see little ovals with (usually) two dots in them. At first I thought that these were LEDs, but that didn't make sense. Now I'm thinking that they are some sort of test point. Odd...
On the Microprocessor Trainer, there are 50 pin headers under the styrofoam (which I should have removed before taking my picture. Duh). I've got plenty of SCSI cables that should fit. The Digital Trainer boards also have a 50 pin connector on them.
Ohming out the power connector shows that the pins in it are connected to the various power pins on the 50 pin headers.
I'll order some 15 pin connectors and build up some cables and give it a shot. Meanwhile, here are some pictures.
