Lambda 8300 and Dragon 32/64, are electronic devices?
Lambda 8300 The Lambda 8300 was a Sinclair ZX81 clone from Lambda Electronics Limited of Hong Kong. It was not an exact clone as it had a modified ZX81 ROM, but could be fitted with a ZX81 compatible ROM. It came with 2K RAM (expandable to 16 or 32 K), and a sound and joystick port. Specifically, it used a Z80A microprocessor at 3.25 MHz. It was identical to the DEF 3000, PC 2000, Marathon 32K, IQ 8300, PC 8300, Power 3000, Unisonic 8300, Futura 8300, Basic 2000 and Basic 3000.
7400 series The 7400 series of transistor–transistor logic (TTL) integrated circuits are the most popular family of TTL integrated circuit logic. Quickly replacing diode–transistor logic, it was used to build the mini and mainframe computers of the 1960s and 1970s. Several generations of pin-compatible descendants of the original family have since become "de facto" standard electronic components.
