I want to make a Leaderboard dongle for the C64, I can get a cassette port connector off ebay just want to know how to make the actual dongle, and I know you can use an actual C64 cassette playre in place of the key but I want to make one! I've read a resistor is connected between pins 1 and 6 but not seen the value, is this correct? Also, was the Leaderboard dongle the same for all versions of the game (Executive / World Class etc) and did it work on other Access games?
Anyone interested for preservation purpose ?
During the school years the teacher made a note of a C64 emulator we were running on the schools 386(?) PC and then showed me a copy of Wizawrite 64 (the school actually had used C64 to produce our electronics courses workbook) with a dongle he had copied. Only recall it having some chip and couple of passives. Ended up removing the dongle check (did something with the pot X/Y inputs) and gave him a disk with the emulator and files.
Right, so a 4k7 resistor should do! What connector did they use back in the day? The ones I've seen are the EDAC 12 way ones in blue or green, the original dongles look to be opaque white connectors!ZrX wrote:C2N just shorts the sense line to ground so pretty much any small resistor works. Use 4700 if you wish.
Now I remember I recently cracked a Commodore 128 utility disk Matrix 128 that also uses dongle. Worked such that you read the pot input and two consecutive reads need to return different values, one larger than the other, but both need to be within certain range.
Been asking for one on various forums and over on Lemon, someone posted a link to a forum that says the resistor is RED RED GOLD GOLD, so 2.2ohms for the colour code! I've bought a couple of connectors off ebay so i'll make one up and try, have a box of various resistors so should get one that's exact or close to it!
EDIT: Also found that mouser.co.uk seems to have the correct connector as found in the C2N plugs: 172879-0206, and the crimp connector: 172160-1805-LP
