Unlike the TMS1000, which had 32 bytes (bytes, not kilobytes!) of RAM, the unit in Dark Tower, the TMS1400, had twice that: 64 bytes of RAM. As perspective, this single sentence using ASCII takes 64 bytes! Bytes weren’t the basic unit: nybbles were (half-bytes, consisting of 4 bits). So, in Dark Tower, the amount of gold, food and warriors a player has are stored as two-nybble BCD representations rather than as traditional binary numbers.

When reviewing the electronic boardgame Dark Tower, I learnt it was programmed using one of the TMS1000 microcontrollers. I’ve since fallen in love with this little processor, discovering that it powered so many other electronic games from my childhood: Big Trak, Electronic Battleship, Merlin, Simon, Speak & Spell, etc.

Dark Tower was one of my favorite boardgames as a kid. It was an “electronic boardgame,” a category that came to life in the late 1970s and early 1980s. Dark Tower really was a boardgame, complete with a board and player pawns (nicely sculpted plastic warriors, as well as a dragon miniature) with a rotating computer assistant shaped like a black tower.
