I replaced the 7406, now the drive is even more irresponsive. Don't know if it's a good sign or not.Boray wrote:It was UB4 I replaced. You can buy it here: http://www.elfa.se/elfa/produkter/se/2012856.htm
I've asked a friend to bring some 6522s and a suitable PSU this weekend, so we'll be able to do some more tests.
I also tested the joystick yesterday, it worked fine in all directions except for right, but that could have been due to the joystick or the joystick port itself, didn't have time to do further tests then.
As for 6522 VIAs, stealing them from a 1541 isn't necessary, since Bejoken (http://www.bejoken.se/) still stocks the Rockwell 1 MHz version.
