I have scanned some of the original documentation used with my first PC, an
IMSAI PCS-80/30 with North Star Disks. From a hardware view point my system
is pretty much an IMSAI, but it terms of the software it is similar to a
North Star Horizon with custom I/O and memory mapped video output. I plan
to submit these manuals to one of the Vintage Computer archive sites, but in
the mean time I put them on a Comcast personal website (file storage). Feel
free to download any of the PDF files which interest you.
