Oric
ORIC 1

This British computer was one of the most popular computers in Europe in the beginning of the 80's. It was a small computer, which was a competitor of the Sinclair Spectrum.

The two models (16 and 48) had the same technical characteristics.
A small plotter was available for this computer.

Notice that the sound chip was the same one used in the Amstrad CPC, MSX computers and Atari ST!

Its ROM was very buggy, & was later replaced with the Oric Atmos.

Greetings,

I have an Oric-1. I bought the Oric rather than a Sinclair ZX Spectrum because I liked the proper bus expansion connector on the back and I wanted to experiment. It''s actually my second one since the cassette input failed in a few weeks on the first. The replacement failed too but by then the Oric-1 circuit diagram had been published in Oric User Magazine and comparing the diagram with what was actually in my Oric-1 (it wasn''t quite exactly the same) I could see part of the cassette interface that looked badly designed so I tried fixing it and it worked!!! The solution, if you have an Oric that won''t load from cassette is to fit a pull-up resistor on the input from the cassette interface to the 6522 VIA chip. I just soldered the resistor under the PCB across pins 18 and 20 of the 6522 VIA. I used 2k2 but 4k7 would probably be plenty. The original design used only the on chip pull-up but I knew from experience that the pull-ups in the 6522 were often very weak.

I remember a friend of mine had one of these. What most impressed me was that there were four built in commands for making sound effects: "shoot", "zap", "ping" and "explode".
