Hi Jeff, I just noticed your post from 2018 re looking for a 16FDC for you PerSci 299. How did you go - did you get it running? I've just started restoring a Cromemco System 3 that has a 16FDC and PerSci 299 in it. I haven't worked with a PerSci drive before. Curious to hear if yours is running reliably, and whether you found a technical manual for it.
