CompuPro - Interfacer I
The Interfacer-I was the first of a series of popular CompuPro
Serial I/O boards.
This board incorporates reliable LSI technology UART
chips to perform the basic serial-to-parallel and parallel-to-serial
conversions necessary for this S-100 dual channel I/O board. By using these
UARTs, the CPU is freed of the time consuming drudgery of performing serial
I/O operations by software techniques. Because of this, I/O operations are
far more reliable and easier to implement.
In addition to the UARTs, several other features are included to make this
board extremely flexible and easy to use. These features include an on board
crystal controlled dual baud rate generator for reliable baud rates
independent of your CPU clock speed, conversion to TTL, current loop and
RS-232 levels for interfacing to almost every kind of serial device, and
hardware/ software programmability for power-on operation and easy parameter
Other features standard to all CompuPro boards include thorough bypassing of
all supply lines to suppress transients. on board regulators, and low power
Schottky TTL and MOS technology integrated circuits for reliably cool
operation. All this and sockets for all ICs go onto a double-sided. solder
masked printed circuit board with a complete component layout legend.
