Punny Little Abbreviation Suitable for This Integrated Circuit (P.L.A.S.T.I.C.)
The MOS 6522 Versatile Interface Adapter (VIA) is a chip usually found handling the input / output of cpu’s in older computers. You can find it in machines like the BBC Micro as well as Apple and Commodore PC’s of the era. It features two bi-directional 8-bit parallel ports, two 16-bit programmable timers, as well as an 8-bit serial port. A serious little chip for its age. But MOS were no strangers to innovation as many of you will already know therefore it’s not uncommon to find this chip paired with the 6502 8 Bit Microprocessor.
