Photo Album1541 Drive Number ChangeJan 27, '08 12:00 AM
for everyone
Changing the drive number on a Commodore 1541 drive... I have not had to do this in awhile.

Observe the jumper "1" near the center of the frame, with the connecting lead scratched out. This makes this a drive "9" -- reconnecting this with a bead of solder will make it an "8" again, which is what the C64 expects.

There are two jumpers that control drive number, and it works like this, if I remember right:

8 - 1 1
9 - 1 0
10- 0 1
11- 0 0

In this image we can see many components that have manufacture dates in 1984.

Did you know the lead hardware engineer for the C128 is on Multiply? He replied to one of my posts and I about fell over.

Bil Herd. And last time I mentioned him, he popped up. :)

I love that I understand nothing about this post. It makes me kind of happy.

You shouldn't. It involves doing stuff to 25 year old computers that hardly anyone knew how to do even when they were new.

that was part of the magic of the c-64. now i gotta find a way to put zaxxon onto a 5 1/4 floppy.
i believe that was the first ever 3-d flight simulator.

You can buy a cable to hook the 1541 up to a computer with a parallel cable. That's how I was moving stuff onto floppies.

Look around on ebay, there is a guy that sells commodore-related cables. He has everything. There's even one that converts c64 to s-video. :) (Had to get one of those out of sheer perversity.)

Man, I had two or three of those machines growing up. Best computer ever..and easiest to hack games on.

They really were great at the time. Still impressive feats of engineering given the technology available then.

They are still somewhat popular... esp. with the Demoscene crowd.

I loved the SID chip in those things. I'm thinking about getting a SID chip modular synth box to toy with.

Well I still have an operating C64 and two working C128s (which can run in C64-compatible mode). I can't say I use them often though. :)
