The original Newbrain, if I may bring back this old thread. A tiny green display and a naff video out.

finally getting round to reading here.
I Nommynate the Motorola D2 Kit. the 'operator' had to
build the two boards it used and unless a lot more $$ was spent
install them on cardboard pages in a loose leaf binder.
THEN get a 5V power supply somewhere, THEN learn Hexadecimal
because the initial programing and output was displayed via 4 7
segment displays.
Came with 128 bytes RAM, and there was room to add another 128 bytes
for a total of 256 bytes.
ANY programming achieved was via a 20 key hexadecimal keypad.
IF one wanted to have a video display and add more RAM or a regular
keyboard then it was time to Build a S100 box and start interfacing
S100 cards.
