Unipolbrit Komputer 2086

Were produced in Poland by PHZ "Pobrit" and probably GZE "Unimor" (so "Uni" is not from "United States"). Comparing to Timex Computer 2068, the buzzer is removed and audio+video connector is mounted on rear side in place of video chinch slot.

Printer slot

Some units have build-in printer interface called "Centromix" or "Centronix" in annoucements. It was made with 8255 PIO and DB15 male slot, that replaced right hand joystick.

Only port PB and PC0, PC1, PC4, PC5 from port PC are used. Below is the male slot described.

The 8255 PIO appars in ports #3B (PA - not used), #7B (PB - data port), #BB (PC - control port) and #FB (RS - 8255 mode). One half of PC is had to be configured as input, the second as output. It is still not clear how the PC was used.

The interface seems to be similar to the PB-3 interface, see below.
