I just finished fixing a dead 5152 dot matrix printer (it had a dead on-off rocker switch of all things).
In the process, I noticed something interesting.
The IBM 5152 was manufactured by Epson and is the equivalent of their MX-80.
Inside the printer, on the control board are sockets for three 2716/2332 ICs.
The Epson MX-80 has one 2232 in it, with two empty slots.
(My IBM 5152 has a single 2716 in it, with two empty slots).
However, this other 5152 that I just repaired has three 2716s in it.
The Sam's Computerfacts for the 5152 shows only one IC.
Any idea why this 5152 would have three of them?
