A $120) The KIM-5 was the model number of the editor/assembler product.

Q $124) Why couldn't regular Atari(tm) style joystcks be used with the
Commodore Plus/4 series?
A $124) Instead of using the de-facto 9 pin D-subminuture connector for the
joysticks, the Plus/4 series used small mini-DIN connectors. Some
sources claim the older connectors were leaking a fair bit of
radio interference and were preventing the units from attaining
FCC approval, so the connectors were changed to the better-shielded
mini-DIN types.
Q $125) What was the first joystick model Commodore produced that would
function with the Plus/4 computer line?
A $125) The Commodore T-1341 Joystick, which had the special mini-DIN
connector

A $126) At last count, 3 models in the Plus/4 series were produced:
The Commodore Plus/4
The Commodore 16
The Commodore 116
Some Commodore 264 models are known to exist, but are not counted,
since the 264 was the prototype model of the Plus/4. Also, a V364
model was planned, but only one unit is known to exist.

the difference between them? Extra Credit: Why?
A $12C) One one keyboard style, the Commodore graphics are printed on the
front of the keys, while they appear above the letters on the keys
in the second type of keyboard. I can't answer the extra credit
part except to say that Commodore was always seeking the best deal.
aybe a new keyboard manufacturer got the bid and changed the layout.

REU with RamDos?

the lever has no such rest visible, the drive cotains the belt drive
mechanism.
