There is also my beloved LM339 Quad Comarator Chip, M74HC32B1 Quad 2-Input OR Gate (ST Micro), Quad 2-Input NAND Gate (Digikey), HM628128BLP SRAM, HIP4081AIP High Frequency Full Bridge FET Driver (Digikey)

MAX232CPE RS-232 Driver/Receiver (Maxim), MAX691CPE uP Supervisor (Maxim), LMD18200T 3A Motor Controllers (National), MC74HCT373AN 3-State Non-Inverting Latch (Digikey), MC41A Brushless Motor Controller (Datasheet), CS82C55A Programmable Peripheral Interface
