The Model 365 Simple Printer Switch is the simplest solution we know of for connecting four PCs to a parallel printer, or three PCs to a parallel and a serial printer. The standard RAM buffer is 256K, and can be user-upgraded to 1 Meg. When using two printers, the PC operators may enter a code to remotely switch printers. Four modular RJ-12 serial connectors on the back keep the Model 365 compact (adapter cables included). The DB-25F parallel connector uses a standard PC parallel cable. Ports 3 thru 5 support 19.200 bps communication. Port 2 (intended for a serial printer or a PC) supports speeds up to 38.4 kbps. The Model 365 is a clever little switch indeed!
