MEK6800D2 6800 Development Kit
Making this computer as small as a pack of cigarettes would be great.
The bytes to be stored in the computer were entered individually and in hexadecimal form.
The address and the current byte were displayed via LEDs. There was no assembly language
programming. Debuggers were also not available. The program either worked or it didn't.

Single-Chip-Microcomputer 8051
When I started developing devices at Endress+Hauser in 1982 as a newly qualified engineer,
the first single-chip microcomputers (8051, 68HC05) already existed.
However, the electronics in a measuring device required at least a circuit board of
100 mm x 160 mm (Eurocard). At that point I decided to develop a computer the size of
a cigarette packet.
And since I smoked Marlboro, I called this the Marlboro-Computer.
State of the art Microcomputer
Of course, that's all water under the bridge now, as there are 32-bit microcomputers in
size of a postage stamp.
