I've got one I accidentally dropped and broke the cover on, and have considered going ahead and scanning the board and drawing up a schematic. Would there be any interest in it? If there is enough interest to justify the time required, I might even be willing to cad up the design of the case and pc board so that a very close replica could be produced. Now for a little history on these modems... The Hayes Micromodem II is a modem for the Apple II series made around 1982-1983. It consists of an internal board that fits in an expansion slot of an Apple II series computer and an external device with a tinted plexiglass cover called a "microcoupler". These were connected together by a 10 conductor shielded ribbon cable. Hayes designed these modems with the telephone to computer interface as a separate unit (since it had to be FCC approved) so it could then be used for future modem models. AFAIK, the Micromodem II was the only modem that actually ever made use of the microcoupler. The microcoupler only has two connectors, both on one end of the unit. One is a 10 pin (one pin removed as a key) header for the ribbon cable, the other is a RJ11 jack for a modular phone cord. -Toth
