C64/VIC20 keyboard adapter

Post by levoman »

The DIY keyboard adapter is now on my website.

If anybody would like to take a look.

Allows the use of a PS/2 or 5 pin din AT keyboard on the commodore64 or VIC20.

"I tend to use mine when i am fixing C64's but there is no reason why it cannot be a permanent replacement!"
So does it work with Games that scan the Keys in a non standard way? (eg Bruce Lee, but there are more)
I'm just a Software Guy who has no Idea how the Hardware works. Don't listen to me.

The MT8808 is a matrix array that emulates the keyboard precisely ( it connects rows to columns in exactly the same way a c64 keyboard would ) and should work absolutely fine . Using this method all the target computer sees is a matrix keyboard!!

Ah! Good :) Just curious - does this reproduce Matrix shortcuts correctly too? eg can it connect one pin of port A to another pin of port A?
