It's just like SRAM, fast at 35 ns, and unlimited read/write endurance. Only drawback is it's 3.3 volts only. I just used level converters. It's a magnetoresistive memory, feels just like core. $12 for a 64K x 16 chip at Digikey. Bob -- Vintage computers and electronics www.dvq.com www.tekmuseum.com www.decmuseum.org
