Does anyone know of a manufacturer for an "OctUART" chip --
an UART chip which has 8 current channels. i.e. The Intel
8250 has one channel, the Zilog SCC has two, and this one
has eight.
What I would like to know is the name of the manufacturer,
plus maybe a model number.
Thanks in advance for any pointers.

I received literature from Systech Corp. (619) 453-8970 back in early 1989 describing their SYC6208P84 8-channel serial communications controller, also known as OCTART. It was in an 84-pin PLCC, 8 independent channels at up to 38.4Kbps per channel, 8char FIFOs on input/output, full modem control plus XON/XOFF, etc. $61 (1000). Don't know if they ever put the chip in full production. Might check with them and see. If anyone has used this chip, I'd be interested in hearing about their success. Come to think of it, I think the new 8-port cards for the Sun S-bus also use a single chip. Good luck.

The Standard Microsystems 1988 data book lists the COM78808, and COM78C808 octal UARTS, in 68 pin PLCC's. These are supposed to be identical to the original chip developed by DEC. SMC also has quad and dual versions. Philip Munts N7AHL NRA Extremist, etc. University of Alaska, Fairbanks
