ISA Port for the Commodore 64 - Etherlink-III LAN Card.
This page last updated: 4-1-2008

There are several CARTRIDGES that you can buy to connect your Commodore 64 to the internet today. The most commonly known are:

(1) "RETRO-REPLAY's-RRNET"

(2) "RETRO-REPLAY's-SIVER-SURFER"

(3) "64NET"

(4) "FB-NET"

(5) "THE FINAL ETHERNET"

And a bit more costly:-

(6) "TURBO-232" cobined with a LANTRONICS interface which lets any RS232 device communicate through a LAN. So if you use the Lantronics interface, you could actually also use a : VIC1011A or SWIFTLINK or any USER PORT RS-232 Interface on your C64 / C128.

(7) "ISA PORT (PC 10Mb LAN CARD) to C64 CARTRIDGE PORT" PROJECT" (WARNING THIS PROJECT DOES NOT WORK ) YET !!!

Recently I looked at the Schemeatics for the 64NET cartridge and was amazed that it was almost identical to a PC's ISA PORT.

Also I have 5 x 3COM Etherlink-III 10mb LAN cards that I was going to throw away because they are too slow for my PC, until the idea struck me to try to use this card on my C64.

I listed all the pins on a PC's ISA PORT in Excel and then started to see if I could find a matching pin that was used to connect to the C64, and as I said, I was able to match up most pins to a function that was already documented in the 64NET Schematics.

As yet I have not been able to get this thing to work , and this is partly because the Etherlink-III Card does not provide all 98 PINS that the ISA Port could use.

As a result I could not tie certain pins to VCC or to GROUND, and I am assuming that this is what is causing the card not to function.

So I am providing all this info in the hope that it may Prevent someone else from wasting there time, and maybe they will succeed where I have not.

So BE WARNED --- THIS PROJECT IS NOT WORKING !!!!! USE ONLY AS A GUIDE ....
