Subject: Keyboard Converter info

    From: Paul E. Woodie <Woodie at DOCKMASTER.ARPA>

    I would like to interface an IBM-type keyboard to my Osborne Executive.
    The keyboard puts out a TTL "ascii-like" serial bit stream and my
    computer expects to see an 8-bit parallel input on the keyboard port.  I
    imagine that someone has done this sort of thing before, maybe even some
    company that offers an IBMPC-keyboard-to-8-bit-parallel conversion
    adapter.  Can anyone offer some information?  I know that I can design
    and build an adapter, but -- just maybe -- someone has already done
    this.

    Thanks in advance, --Paul Woodie (Woodie at dockmaster)

First off, the IBM keyboard sends serial data of key number NOT ascii.
It sends the key number when the key is pressed, then sends key#+80h
for key release.  For info on an adapter see Micro/Systems Journal issue
