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.

    Bought an ‘untested’ BBC Micro on eBay, during a bout of nostalga for 8 bit computing in the ’80s. The machine didn’t boot, but diagnosed the problem to be with the VIA after swapping IC3 and IC69. I thought a replacement would be difficult or impossible to get at a reasonable price, so I was delighted to be able to source one from HackerSpace. Really knowledgable, super helpful, and great customer service. Many thanks.
