You really can get it working with a byte-wide SRAM, a 4MHz clock, a TTL-RS-232 level shifter and a few baud-rate-select resistors. I just found a couple of rudimentary 8073 schematics in EagleCAD format, but there's nothing there that isn't in the Nat'l Semi reference design, really. I still have to complete my MC-1N schematic capture (2K RAM, 2K/4K ROM, MM58174 clock, 8255 PPI, 82S23 address select PROM). -ethan -- Ethan Dicks, A-333-S Current South Pole Weather at 1-Apr-2008 at 02:30 Z South Pole Station PSC 468 Box 400 Temp -59.8 F (-51.0 C) Windchill -100.3 F (-73.5 C) APO AP 96598 Wind 17.2 kts Grid 35 Barometer 690.2 mb (10246 ft) Ethan.Dicks at usap.gov http://penguincentral.com/penguincentral.html
