Notes
Nicknamed the "SymbolMaster", this keyboard was the first IBM Enhanced layout keyboard that came into my possession. It came in working condition but had a pretty battered case, which after some tactful magic eraser work was recovered into decent condition. I decided to add Unicomp's APL keycap set to it to compliment the overall symbols focus of the keyboard (ie, the ASCII characters on the numpad). Other keycaps added include red Esc, red Ctrls and blue Alts from Unicomp, and some PC keycaps recovered from various sources to replace the originally terminal-centric ones on the nav cluster and surrounding the numpad. The extra key granted from the split numpad plus key arrangement outputs a comma to match the keycap's legends (which I kept from the terminal layout since it matches with the symbols aesthetic).
