VIC-20 Final Expansion
- expansion of the main storage (SRAM) of 512KB
- a 512KB-sized flash memory (EEPROM) for the firmware and often used programmes
- a mass storage as floppy substitute on the basis of an SD card (SD2IEC) for up to 2GB
- a real-time clock and a connection for the LCD display expansion of the SD2IEC
The final expansion can start every known VIC-20 software. Starting of games and programmes can be done comfortably over a menu. The FE offers the software the required surrounding and adjusts it automatically (memory configuration).
The firmware of the FE3 is stored in flash-ROM and is available right after switching on or resetting the VIC-20.
RAM configuration: This menu item lets you adjust all known memory configurations of the VIC-20.
Diskloader: This menu item supports the comfortable loading and executing of programmes. The diskloader is freely configurable and supports all types of floppy disk drives and of course the integrated SD2IEC.
Cartloader: With this you can start the programmes comfortably, which are stored in the memory. In the flash 480KB (of 512KB) are available. Everyone can transfer his favourite programmes into the flash memory. You can pogram any programme (BASIC, programme, cartridge) into the flash memory.
FE3 Wedge: This small tool expands the instruction set of the VIC-20 and implements SJLOAD/SJSAVE (Jiffy compatible loading and saving). As the integrated SD2IEC is also Jiffy compatible, one profits directly (also in the diskloader) from the speed advantage that the SJLOAD offers.
The plans for the FE are freely available and the software is Open Source. For skilled amateurs or electronic technicians the interface is easy to build. If you don't want to create a board yourself, you can also build the FE on an 8 Bit Baby (see also Final Expansion v1).
