🎄💾🗓️ Day 3: Retrocomputing Advent Calendar presents the Commodore VIC-20! 🎄💾🗓️

The VIC-20 ⌨️📺🕹️, released in 1980 by Commodore, was the first computer to sell over a million units. It had a 6502 CPU running at 1 MHz, 5 KB of RAM (expandable), and displayed up to 22 characters per line on a color-capable screen. An affordable and friendly computer, the VIC-20 was great at games and basic programming and was supported by a library of software and peripherals. It connected to TVs for display and included Commodore's BASIC interpreter for programming. Its success allowed other computers like the Commodore 64 to make its mark.

And since this is a #firstcomputer celebration here's a fantastic story from Jeff -

My first home computer was the Commodore VIC-20. I must have been in second grade (1986/1987). My Dad was working somewhere away from home, but one weekend Mom drove us two kids to spend the night at the motel that was his home base.

He had bought this computer, the VIC-20, and hooked it up to the hotel TV. I remember entering the program pictured below (probably Mom typed it in, actually) and being blown away by the birds flapping their wings across the screen.

The other distinct memory I have is the next morning my folks woke me up and asked whether I was hungry. No, I very much wanted to play with the VIC-20, so I made up the most obvious word that came to mind: "No, I'm Vic-y". I think they were very puzzled. We probably went and had breakfast regardless of whether we wanted to see the birds flying again.

🎄💾🗓️ Day 15: Retrocomputing Advent Calendar - BBC Micro🎄💾🗓️⌨️🇬🇧

The BBC Micro was an 8-bit microcomputer introduced in 1981 by Acorn Computers under the BBC Computer Literacy Project of the UK, launched with a 6502A processor running at 2 MHz, supported 16 KB to 32 KB of RAM, and featuring a BASIC environment. The machine was versatile, having very good-for-its-time graphics and multi-colors. Expansion capability for educational and experimental use with an assortment of I/O ports, which included a 1 MHz bus, user port, and cassette interface.

The BBC Micro was known for its reliability and emphasis on teaching programming and computer science. The system software, Acorn MOS, was simple and intuitive. With peripherals such as floppy drives and second processors, it performed tasks well beyond its initial use and extended its lifetime by at least a decade or more.

The BBC Micro also pushed forward a lot of gaming and software since this open architecture inspired a thriving community of developers. It also played a big role in the development of the ARM architecture by Acorn Computers, which would change the way modern computers are made in years to come. The BBC Micro has a special place in computing history, which expanded education and brought computing to schools and society through the 1980s.
