Were both Memotech MTX and TEC-1 single-board kit computers?
TEC-1 The TEC-1 is a single-board kit computer first produced by the Australian hobbyist electronics magazine Talking Electronics in the early 1980s. It was based on the Zilog Z80 CPU, had 2K of RAM and 2K of ROM in a default configuration. Later versions used a 4k ROM with two different versions of the monitor software selectable via a switch. This allowed the early software presented in the magazine to be used with the later version of the TEC-1.
EMIDEC 1100 The EMIDEC 1100 computer (became the ICT 1101 in 1962) was produced by the Computing Services Division of EMI Laboratories in the UK under the leadership of Professor Sir Godfrey Newbold Hounsfield in 1959 after one year's development. It used magnetic core memory and transistor technologies and it is claimed to be the first large commercial transistorised machine in the UK.
