Why Was the Commodore 1541 disk drive so slow? Commodore History 2024-01-18 | UPDATE: I created a follow-up video to provide more accurate benchmark tests for the drives I discussed in this video: youtu.be/7SPr5S0eEYM?feature=sharedLike millions of other kids, I had a Commodore 64 with a 1541 disk drive when I was growing up. For all the great memories I have of that system, I don't fondly remember how slow the disk drive was. All I wanted to do was play a game of Racing Destruction Set, but I'd have to wait seemingly forever for it to load. I preferred the instant option of playing games from cartridge, but all the great games were on disk. Fast loader solutions worked, so why didn't Commodore just make the 1541 faster in the first place?This video explores Commodore's history in the disk drive market and explains the intentional cost-cutting and incredible bad luck that resulted in the 1541's dismal performance.I worked on the technical parts of this video in collaboration with Andrè Fachat, and he did his own video on the technical details of the 6522 shift register bug where he gets deep in the weeds. Please take a look at his video if you enjoyed this one: youtu.be/6cwVQahVCdc
Commodore b128 Power Supply (and clock generator) Replacement Commodore History 2024-05-26 | The power supply in this Commodore b128 failed and shot sparks out of the case. Because I lack the knowledge to diagnose and repair it, I chose to replace it with a modern power supply from Mean-Well. In this video, you'll see how I went about mounting the new power supply in the original PSU case to preserve the original look, and you'll see how I dealt with providing a clock signal, which the original PSU provided but the new Mean-Well did not.In the video, I mention a clock generator circuit that Steve Gray designed a board for. If you're interested in using that board for your own CBM-II PSU replacement, you can find more information about it on Steve's website: http://cbmsteve.ca/cbm2clock/index.html
April 2024 Update and Whats in the Box?!? Commodore History 2024-04-29 | This is a quick and dirty, low production effort video just to let you know what I've been up to and what I'm working on now. Most of the video is spent giving you a preview of a box of Commodore documentation that was sent to me by former Commodore staffer, Michael Tomczyk.
How Does Epyx Fastload Make Loading Faster on a Commodore 64? Commodore History 2024-03-24 | This video does a fairly deep technical dive into exactly what the Epyx Fastload cartridge does on a Commodore 64 to make loading from a Commodore 1541 disk drive faster. I use a logic analyzer to trace the signals on the bus and explain what's going on every step of the way, comparing Epyx Fastload wire protocol to the standard Commodore serial bus wire protocol.To learn how Epyx Fastload works, I did a complete disassembly of the Fastload kernal load routine (not the entire cartridge ROM), including the code that is uploaded to the 1541 disk drive by Fastload. These files have been uploaded to zimmers.net.Epyx Fastload Kernal Load routine source (relocated to $C000):http://zimmers.net/anonftp/pub/cbm/c64/diskutil/fastloaders/epyx_fastload_kernal_load.asmEpyx Fastload 1541 Disk Drive disassembled source code:http://zimmers.net/anonftp/pub/cbm/c64/diskutil/fastloaders/epyx_fastload_drive_code.asmIf you'd like to run Epyx Fastload from disk instead of cartridge, I created a d64 of my assembled, relocated code:http://zimmers.net/anonftp/pub/cbm/c64/diskutil/fastloaders/fastload.c000.d64.gzI said I would do some benchmark tests using Epyx Fastload, but the video got long on me, so I'll do some benchmark testing later.Thanks for watching!!!
Update to my previous video on why the Commodore 1541 disk drive was so slow Commodore History 2024-01-23 | This is an update to my most recent video: youtu.be/kaeFV0oZaps?feature=sharedI mentioned in that video how terrible my benchmark methodology was, and a few folks commented on the poor performance. I realize that I'm giving Commodore drives a bad name across the board if folks think that's typical performance.This video was created to set the record straight about Commodore disk drive performance. The 2040, 2031, 1540 and 1541 will be vindicated!
