the CPU on the card is an NEC V30. it is a faster clone of the Intel 8086. the ceramic chip you can see on the left is an 8087 floating point coprocessor.

oddly, the floppy chip is from Apple. the part number is 010-0101-0, which is a special floppy controller chip that supports both GCR (standard Apple II) and MFM. the card has a separate 19-pin floppy port.

@tubetime thats the SWIM chip (or some version of it), with Woz's GCR stuff and Wendell Sander's MFM stuff on it. Wendell had been running The Engineering Department, which did work leading up to this PC Transporter.

It isn't jumping out at me, but wasn't the card designed by the Engineering Department (ie. the Saunders)

@bitsavers ahh that explains a lot. the card really feels like it was designed by Apple so i figured it was done by ex-Apple engineers.

@tubetime @bitsavers
So apple engineers in 1987 producing an MS DOS card for the apple ii

Wonder how hard it'll be to make a Macintosh card for the apple ii
