In the late 70's and early 80's, memory chips were expensive. As such, computers were often sold with a very minimal amount of memory with a means to expand them later. This is why cartridges were favored for video game consoles; people would purchase the consoles, then as memory dropped in price, more sophisticated games were made available.


The Vic 20 was designed to compete directly against video game consoles. At the time, the selling point for video game consoles was their ability to bring arcade hits home. The Vic 20's limited memory meant that cartridges were the best way to achieve this. As memory prices dropped, we would see more sophisticated games.


Since the Vic 20 was a full fledged computer, various types of software besides games (brown case, not beige) were released on cartridge format to get around the 3.5k limit. Much of this software took advantage of the Vic's peripherals. For instance, the Vic music composer allowed the user to save their music composition on tape. Terminal software made use of the VICModem.

Note that Xonox carts sometimes came two-per-case, as "double-enders".
These carts had 2 sides (front and back?) that plugged into the VIC-20.
The initials seen above show what cart was paired with what other cart.
All of the Xonox carts above were made as both single and double-enders
but only the double-ender's part numbers are shown in the list above.


At the end of 2006, after numerous discussion concerning the usage of octal flip-flops or latches connected to the IO2 and IO3 lines of the VIC-20 as a means of selecting a particular section of a large capacity non volatile memory, two different projects were started to create multicarts for the VIC-20.

The Behr Bonz multicart

The Behr Bonz created by Eslapion in 2008 is geared towards a "historical preservation only" approach with a content of 127 games that were all originally published as cartridges and all of these having being available as commercial products prior to the VIC-20's production being stopped.

The first production run of the Behr Bonz has sold 100 units worldwide with two additional pre-production units freely donated to the creator of the menu system, V1and3, and the designer of the promotional web page, AlanR.

This product was available in NTSC and PAL flavors with content selected and screen adjusted for respective systems. The price tag of 30$ US per unit was the same for both variants with only the content of the 27C160 EPROM being different.

A second production run of 81 units began shipping in May 2015 and sold out in June 2016. This run had an improved menu from e5frog which allowed to jump directly to any specific game by pressing a sequence of a number from 1 to 8 followed by a letter from A to Q. It also carried a 'Reset to Menu' button which allowed the selection of another game without the need to power cycle the VIC-20. Initially offered for 48$US, the price later dropped to 36$US per unit and was the same for both variants.

The Behr Bonz is currently out of production and unavailable.

The Final Expansion

Final Expansion

The Megacart

The Megacart is an all encompassive cart which provides both multicart capabilities as well as RAM expansion. Unlike the Behr Bonz, the Megacart contains games as well as utility software published as cartridges or on disk or tape. It also contains utility software and games created after the VIC-20 was no longer produced.

The Megacart is expected to be released in 2009 with a price tag of approx. 100$ US.

The Megacart's hardware was created by 6502dude and the menu system by Carlsson and NBLA000.

The UltiMem



The Ultra Vic-20 Cart

The Ultra Vic-20 Cart is being created by fsporsche(Fred Santos) It will have every program ever made for the Vic-20 with a plus feature of a SD/Card reader built in.

The Ultra Vic-20 Cart is in Development and is expected to be released in 2011 with a price tag of approx. $99.00
