TI-74
The Texas Instruments TI-74 Basicalc is a type of programmable calculator, which was released in 1985 to replace the Texas Instruments Compact Computer 40. One variant, the TI-74S, has a blank faceplate instead of secondary functions to allow for customization (otherwise it is the same as the 74). Both models accepted customized ROM-modules. The TI-95, released at the same time, was a keystroke programmable descendant of the TI-59 and TI-66, with the same general form factor, but a two-line display (the second line was for function key definitions).

gollark: For labels, 20Hz.
gollark: For redstone, yes.
gollark: Labelnet could do 600B/s, though, it's way better than 20B/s from Bundlenet.
gollark: I got the basic stuff worked out ages ago, primarily just the 256→187 encoding, but I never figured out how exactly it ought to work for actual use.
gollark: > Heh.. This is as bad as using labels for communication between side touching computers.I really should work out the high level labelnet API!
