"SerialControl" is application and hardware device to control external
devices using Macintosh through serial port of Macintosh.

It is really hard to interface something to Macintosh unlike old Apple
II or IBM-PC. The slot of AppleII and ISA(or EISA) of IBM-PC(or
compatible) has relatively simple structure and protocol. Currently PCI
bus or direct slot of Macintosh is too complex for personal hobbyist to
interface something like ADC, DAC, digital port. "SerialControl" might
solve this problem somewhat. "SerialControl" is application(including
sources) and hardware device(to make by yourself). It uses serial port
and provides 8 TTL outputs and 8 TTL inputs with current circuit, but
you can easily expand to interface to other device like ADC or DAC.


You require special LSI CY233 from Cybernetic Micro Systems. Actually,
CY233 is powerful LSI for serial-parallel conversion or network.
"SerialControl" just utilizes one of its operation modes. Only demerit
of this LSI is price. The price is $45 each(16$ per 1000) except S/H.
Foreigner may pay more.

This "SerialControl" is absolutely freeware. You can use this circuit,
source, and application for your personal use(absolutely not for
commercial use). If you are going to include in CD, magazine, FTP
server, or web server(except Info-Mac archives and its mirror server),
please let me know.

If you have any questions, advice, comments, or corrections, please let
me know. I'll really appreciate. Here is information about me.
