This DayStar machine has four 150MHz processors on a 9500 motherboard.
Upgraded with one DIMM at a time.
Can interleave memory for approximately 10-30% faster RAM access. For the fastest speed, sockets A1 & B1, A2 & B2...A4 & B4 should contain identical capacity DIMMs.
Serial Port with the phone icon supports synchronous modems, with handshaking on both output and input supported.
