This is my second attempt at making a general purpose board for my pic 877’s. This time the plan was dont connect anything. So the only connectors on the board are iscp, power, and a 40 pin header.

My idea behind the 40 pin header was to be able to connect this board through a normal ide cable to other stuff. I had planned a nice clean structure for the pins, but after soldering things went wrong. Its very confusing when everything is backwards and upside down. None the less its mostly consistent.

So far its working well. The only problem i have had is shorting the +- and blowing up a pic, also the ide cables for more than one drive dont seem to work with it. I dont think ide cables that go to more than one drive are “straight through”.

For anyone curious about version 0.1 you can see a picture here, its in a box ill pull it out and do something useful with it one day, its pretty stable. Its just too big.

I’ll write more about this as i use it, im kinda in a hurry now. I want to do a little more and write a little less, but i also want to document everything i do. Even if I’m brief.
