To kick off the range, I have designed a simple RAM cartridge for the VIC20. That's it, a RAM cartridge. No buttons, no DIP switches, no LEDs, no game ROMs, no graphical menu. Just a RAM cartridge, but a nice one.
Plug it into your VIC20 and switch on, and you will see a menu (very much in the style of the original Penultimate Cartridge). From this you can select how much RAM to add to your VIC20. The four unshifted function keys give the most popular RAM configurations.
- f1 - 0K, unexpanded VIC20
- f3 - 3K, 3K RAM in block 0
- f5 - 8K, 8K RAM in block 1
- f7 - 35K, 3K RAM in block 0, 4x8K RAM in blocks 1,2,3 and 5
The shifted function keys give a further four RAM configurations
- f2 - 16K, 2x8K RAM in blocks 1 and 2
- f4 - 24K, 3x8K RAM in blocks 1, 2 and 3
- f6 - 27K, 3K RAM in block 0, 3x8K RAM in blocks 1,2 and 3
- f8 - 32K, 4x8K RAM in blocks 1,2,3 and 5
Once the RAM is selected, the VIC20 will be booted and will continue with the amount of RAM selected until the power is removed. As ever, BASIC does not count all the RAM, so the maximum you should ever see is 28159 bytes free, but the RAM in block 5 (and block 0 when there is RAM elsewhere) can be used for assembler programs or ROM images etc.
At this stage we are not planning to include a printed sleeve, but you can download and print your own. Here is an artist's impression of how it could look.
The VIC Max RAM cartridge is available to order now from The Future Was 8 bit webstore.
