Does anyone know of an online source for the manual for the optional I/O (IOM-MPF-1P) board for the microprofessor MPF-1?

There are a few web pages which have just about everything else to do with the machine on, but the manual for this particular accessory board is always conspicuously absent. It is an official board - it's in a system / accessories brochure that I found online.

For identification, this is the add-on board which has 3 * 2K RAM sockets, 1 * 4K rom socket, 1 Z80-PIO, 1 Z80-CTC, and an 8251 UART and associated level shifting circuitry on board.

My company used to sell the Microprofessor in the 1980s. They were popular with schools and technical colleges. Later, Multitech changed its name to Acer and became a major PC manufacturer. The founding president, Stan Shih, was a national hero in Taiwan and must be very wealthy by now. http://en.wikipedia.org/wiki/Stan_Shih

Working for a museum in the 1980's I remember finding a Micro-Professor running one of the exhibits. You'd press a button (one of 11 or 12 or so), and it would flash a series of LEDs on a (large) map showing some shipping route, together with a number of something like 2x40 line LCDs placed on the map giving other information. Not exactly rocket science, but some form of microprocessor was necessary due to the LCDs.
