Applied Processor Labs

I found another computer not on the list and one I don't have much info on. This one is an Applied Processor Labs APL/80 Microcomputer System, is an S-100 system, and uses an 8080 CPU. It has 64K of memory on a Model DM6400 Measurement Systems and Controls, Inc. board. It is one of the boxes with no internal floppy drives, and uses a Vista Computer Company floppy controller card connected to two Vista external floppy drives. It has an IMSAI SIO rev 3 board along with the APL 2 board CPU set and APL PIO card. There is one wirewrap interface card of some sort in the machine. I picked it up a couple of years ago at the TRW swap meet in Los Angeles. From what I can remember, the guy said it was built by some people associated or formerly associated with Intel. The wirewrap interface card was used (as I recall) for some sort of sign lighting control. I thought I had some documentation on it but I don't see it (yet.) Anyone know anything else about this machine? Thanks.
