This is an Cartridge for your C64.

It can hold one or more programs (64K or 128K EPROM) and start it using a program list.

The UC1 can:

• run a 8KB Cartridge
• run a 16KB Cartridge
• run a Ultímax Cartridge
• run a PRG Files which start with RUN (Load address $0801)

Cause UC1 has RAM it can load programs also from a disk drive or a SD2IEC and start it as Cartridge.

UC1 RAM can be write protected so it is like an EPROM.

For the EPROM any 64K or 128K Type can be used. It is possible to use EPROM (like 27512) or EEPROM (like W27C010). The UC-Tool calculates free memory for 128K EPROM. For 64K EPROM you can only use aup to address 0x10000.

The UC1 cartridge can be configured fully using an IO register at $DE00.

It can control /EXROM and /GAME so C64 know which kind of cartridge is mounted.

You can disable the IO register and make the cartridge fully invisible (up to next hard reset).

There is a command line tool (UC-Tool) for Windows, which can create Image Files for the UC1 cartridge. Simply copy CRT or PRG files to a directory and create a small textfile (CSV file). UC-Tool will make an Imagefile for your EPROM prgrammer (for example TL866). CRT files are Cartridge Files for VICE (only Typ 0 allowed: 8K, 16K, Ultimax). PRG are files you can LOAD and start with RUN (OneFiler).

There is also a file browser (modified FB v2.0) which can load and start programs from a disk drive or an SD2IEC. The difference between UC1-FB and the normal FB is, UC1-FB can load and start CRT files directly. CRT files must be type 0 (8K, 16K or Ultimax). After loading the CRT file it will be copied into UC1 RAM and started with a Soft Reset.
