Exploring and fixing a rare Commodore 1551 disk drive - floppies rock ep8

In this episode I explore a rare Commodore 1551 disk drive, fix it in the process and learn a little bit about BASIC v3.5 on the Plus 4 and Commodore 16. I also do a head-to-head speed test of the 1551 against a 1541 loading Lemmings. Timestamps: 00:00 Intro 00:21 First examination 00:57 Taking a look inside 02:39 Testing the read/write head 03:29 Testing the drive 10:21 Testing with replaced drive mechanism 14:31 Testing again 17:48 Using the Plus 4 again 19:55 Testing 1551 and 1541 speeds 21:48 Wrap-up Problems with this drive: The read/write head on the Newtronics/Mitsumi mechanism had failed with some of the coil resistances being 15k ohms. I replaced the drive mechanism (including the head) with another identical mechanism from a 1541 drive. The cartridge port on my Plus 4 and the cartridge connector on the 1551 were a bit dirty - some cleaning fixed them both. Video content copyright (c) 2024 piers.media Limited. All rights reserved.
