The first portable digital computer that weighed less
than 1 kg on the
Earth's surface was introduced in 1974, and had a mass of just under
0.32 kg. It was weightless when it was in Earth orbit on the
Apollo-Soyuz Test Project. Identifying this computer is left as a
challenge to the reader.
Am I anywhere close ?
The code name was 'Superstar'
The CPU was (part of) a 6 chip hybrid module with 44 pins. The only other
chips on the logic board were the firmware ROMs
It was user programmable and could store the user programs on little
magnetic cards
The programming language was RPN-based
In other words, it's one of the machines I suggested -- the HP65
