For Commodore 64 fans, if they want a really useful accessory:
If you have a Commodore 64 computer, buy this utility collection card, as it turns an otherwise cumbersome machine into a very easy-to-use, handy tool. Anyone who has already used one cannot imagine how it was possible to do without it until now. This is not a cartridge with accessories, nor is it some primitive fast charger: it contains almost everything you need for the C64. Its Hungarian-language, pixel-by-pixel scrolling menu system can be operated from the keyboard or with the 2 joystick. There is a reset button on the back of the card, which, when pressed, also stops games protected against reset and immediately starts the card's menu without turning the C64 on and off. The active status of the card is indicated by an LED. (These are clearly visible in the pictures.)
This Commodore 64 cartridge is the 2021 version of my C64 card made in 1998, made with modern components. The card is the smallest among existing cards, so it is very convenient to use.
Briefly about the programs it contains:
- Tape fast charger (Turbo): 62 kB! size file operations + extra functions (saving and loading a given RAM range (e.g. for machine code programs), checking: comparing the program in memory and the program on the cassette without loading the program in the memory, automatic listing of the programs on the cassette: scans the entire cassette and saves in a list file the name and size of the programs found, count of saves.) Loading can be interrupted at any time with the RESTORE key. This turbo program is compatible with the others and runs without loading into RAM, so it does not overwrite its contents.
- Tape head adjuster (with Hungarian text, marker lines): for a cassette saved with a tape recorder with any head position, you can adjust the head perpendicularity of your tape recorder in a few seconds.
- Floppy fast loader (for 1541) Gigaload (with automatic listing, so it is much more convenient to use than the normal Gigaload program) and Disk Loader for those longer programs that Gigaload can no longer load.
- Copier between disc and cassette
- Disc monitor
- Sprite viewer: shows the entire RAM area as a sprite bitmap.
- Profi Ass-64 (two-thread assembler for writing machine code source programs)
- HESMON 2.0 monitor program (for machine code programming)
- SIMON'S BASIC 2.0 (the popular BASIC extension)
- Hardware testing programs (for joystick, keyboard, monitor)
- Stopwatch (two stopwatches on one screen, with giant digits)
- Reaction time measuring program with millisecond resolution.
- Additional functions (e.g.: restoring a BASIC program deleted by reset, exiting without removing the card, deleting RAM.)
- Simple polyphonic synthesizer program.
- RESET push button, so the card menu can be activated at any time without turning off the machine (it also stops programs protected against RESET).
