Josh ‹ No, this board is rock-solid. I have several and use them on every system I have. The other one I like is the Interfacer I.
The model I have on this test system uses double-wipe sockets, not the enclosed ones you describe. I¹m just having problems with it and the 16-bit CPU (8088) board).

I mentioned recently that mine was causing ghost characters, fixed after reseating the chips. I should also note that it had another problem 2 years ago when I first started using it (while bringing the IMSAI back to life). It would seem to work fine, then after sending a large stream of characters to the Terminal (all correctly) it would send the last character a few extra times... kind of like a car engine with run on. It was funny to watch... because it would eventually stop, but it slowed down first. Just like engine run on... first it sputters, then it dies after 1 or 2 last kicks. I never did find the exact cause (at the time, I was getting tired of fixing everything else that had gone bad on the IMSAI), but it did correct it self after reseating the chips. I am particularly interested in what type/make of sockets are on your board... I believe all of mine are "RW". Contacts are hidden, open frame type sockets.

No. I don't think the right schematics and board plots are posted for that version. Right now I'm building the Prop IO board. I can't get the 8088 board working with my vintage Solid State Music IO4 board (which works fine with the z80 board). I also can't seem to get the right jumpers for master mode.
