The 1541EMU cable connects Commodore machines to the PC parallel port and, concentrating on file serving purposes, is constructed for maximum reaction speed on the PC side. It's compatible with all kinds of parallel ports and with all Commodore machines that have the usual serial bus port.
You need the following hardware to make use of this cable:
A PC with a parallel port
A Commodore 64, 128 or VIC20 machine, or any other Commodore machine or clone that has the usual serial bus port
The cable is supported by the following PC software:
This page discusses the type 1 cable, which uses only two IC's and, therefore, is easier and cheaper to build. The type 0 cable needs significantly more electronical parts but, in change, is electronically more compatible with the Commodore serial bus. However, practice shows that the type 1 cable is also compatible enough. For the description of the type 0 cable, see the 1541EMU homepage instead.
Method 1. If you can't or don't want to put the electronical parts onto a small board, you may solder them together with simple wiring. You can find the details on how to build this cable at the construction page.
Method 2. A more reliable and elegant solution is to put the complete circuitry onto a small board and hide it inside the case of the parallel plug. You can find the details on how to build the cable, with this board, at the construction page.
The assembled cable for Method 1 looks like this: complete cable, bottom of parallel plug at PC end, game port plug at PC end, DIN plug at Commodore end.
The assembled cable for Method 2 looks like this: complete cable, top of parallel plug at PC end, bottom of parallel plug at PC end, game port plug at PC end, DIN plug at Commodore end.
These pictures should give you an overall idea on how the cable looks like and how it should be properly assembled. However, when building a cable yourself, you should not rely on the pictures only; see the construction guide instead.
Connect the serial plug into the serial port of your Commodore machine. Connect the game port plug into the game port of your PC. Connect the parallel plug into the parallel port of your PC.
Important! Do not plug or unplug cables while your equipment is switched on. Make sure that all components of your equipment are connected to the same, properly grounded power outlet. Put your equipment far away from monitors, TV sets and other devices with strong emission, otherwise cables may pick up interference and you may experience data loss or corruption.
