The Infinite UC1800 is similar to the Elf and Microtutor II, just a CDP 1802, hex keypad, switches, LEDs and TIL313s.
The manual is supposed to have listed a short keybug program serving as a simple monitor and debugger program. As we have not found the original manual I have written a keybug_2020 program myself which executes the commands as described in the article about the Infinite UC1800 in the Radio Electronics - August 1977 magazine
