What this file contains |
|---|---|
Hook-up instructions, right out of the original owner's manual. |
|
Graphics from the original user's manual. These two pictures show where everything plugs into a real Vic20 computer. |
|
Hints on how to hook up a real Vic20. This chart was originally in the user's manual that came with the Vic20. |
|
The top few Freqently Asked Vic20 Questions, answered. |
|
Some general tips on scanning things into an IBM compatible, by using a flatbed scanner. |
|
More image scanning tips, including a step-by-step way to make cart scans look really nice! |
|
This is an ascii text file of a BASIC program I wrote. It is used to see whether RAM or ROM (or nothing) is plugged into a real Vic20. You can use it to play with and set the switches inside a RAM expander, or use it to help archive rom images. |
|
This ascii text describes ways you can keep the operating parts of any of your older computers cooler, so that they last longer. (Someone else wrote it; I just think it is good information!) |
|
| A text I wrote, which talks about straightening bent IC legs, repairing broken ones, and so on. | |
| A hardware project you can do. This includes instructions and pictures telling you how to modify a standard Commodore C2N datasette so that it will allow you to make perfect, digital copies of your old software stored on cassette tapes. | |

This 57k program is used to hook a real 1541 disk drive to an IBM computer, for transferring software back and forth between those two computers. Requires a special cable be assembled. Schematics are included with this program if you want to build your own, or pay someone to make one. (Sorry, but I can't offer you anything besides the program itself. I don't have the time or the inclination, and last but not least, I don't want any blame for hurting your hardware!) |

This is one 88k zip file, containing four texts about technical subjects. It also includes two related utility programs. Besides pinout diagrams and general Vic20 cartridge port info, this also explains cartridge archiving methods. |
|
This 40k zip file contains a utility program for the IBM which reads a "raw" image file (one with no load address info in it) and then makes a second copy of it which contains that info. This allows raw ROM images sometimes found on the I'net to easily work with emulators or real Vic20's. Includes docs, source code. |
|
| This 27k zip file contains a utility program Ward wrote for IBM compatible machines. The program compares two files and tells you how many bytes do not match perfectly, and where they do not match. Very useful for comparing two binary files, such as ROM images. | |
