i have 3 of the cmd fd-2000. are they worth as much as the 4000? because i inherited them i don't know how to test them. is there a way? they all do indeed power on .
Really enjoyed your content. I grew up with the MSX and never had the chance to use a C64 but I think it was the best 8 bit computer ever made. It's really impressive that this disk drive came almost 10 years after the C64 release.
I have an FD-4000. Still works. The drive itself is a standard 3.5" ED drive. The interface board is proprietary CMD. Bought mine 1/29/93 and I still have the receipt. That is the depth of my illness... It was $299.95 and I also bought a box of 10 3.5" disks for $60!! The good ol' days...
That box of 10 - 3.5 inch disks must have been Dysan. I remember when one 3.5 inch disk sold for $3.50 to $5.00. This was back when the 3.5 inch drives first came to market. I dreaded buying disks for my new Atari 520ST and Commodore Amiga computers back then. The disks were so damn expensive.
@@HansCampbell Yep, that's the way with newer formats. I remember owning one of the first available (write-once) CD burners - blank disks started at $25 each back in that day. Buffer underruns hurt like hell. :)
1. The IC "FD-4000 DOS" isn't JiffyDOS, but it's the ENTIRE DOS. It is 32K and contains CMD's standard partition and file systems and serial transfer routines (slow, 128 fast, 128 burst, jiffydos). 2. The same PCB here was used on the FD-2000 and 4000. The missing IC to the right of the 82077A disk controller (which supports ED/Perpendicular recording) is for the smaller disk controller IC that only supports DD/HD operation that was used for the FD-2000. 3. No, you should not just throw different LEDs in there without recalculating the series resistor.
Both the FD-2000 and FD-4000 had a RTC option that installed under the ROM Chip I believe they were made by Dallas and had batteries that are probably dead now.
May I suggest introducing a bit more about the stuff like what kind of ICs are used, what lies bottom of the pcb, may be connecting a computer and show it while it is working ...etc for the next video.
Yes it's ineed an ED drive. The FD-2000 was the HD floppy version. The 2000 and 4000 were evocative of the 2 megabytes and 4 megabytes unformatted capacity of HD and ED floppies respectively.
I am going over one of these drives but I don't have a power source. Don't know whether it runs. That sticky stuff comes off the rubber feet and gets all over everything. Put mine on card board.
Ok, I did have to change the jumpers on the mechinism unfortunately. However I still have no power at all and I was unable to see thar header next to the ribbon cable on your board. Does there happen to be a jumper on that header by chance? Thanks so much GREAT VIDEO! Charles
I have a clone FD2000 that got a 12 VDC in it by mistake and it burnt it does not work. I am just waiting to find some one knows how to fix it. It took 5 volts
Since you shot 12 volts through that board, every chip is fried. The PCB is most likely burned in a few places too. The disk drive is probably also fried. So, no fixing that poor drive. You could sell just the case on eBay for $129.95.
I can not justify keeping an old disk drive, for the Commodore 64 computers, that sells on eBay for $800. So, usually after I show a vintage computer item on my channel, that sells for a lot of money on eBay, I sell it. The exception to this are Amiga computers, hardware, and software. In my professional opinion, the Commodore Amiga computers are the only vintage computers worth collecting and using today. I also like older PCs.
@@HansCampbell I still use Commodore 64 stuff and Vectrex, etc. Hard to find information on old stuff. Heck, 4K recordings would be good too. Why I encourage others with retro tech to document everything that can be at as high a resolution that can be.
The really insane thing about this device is that it supports ED (Extra/8x Density) floppies. Almost nothing used those, even on IBM PC clones, because other much larger formats were becoming available. e.g. LS120/ZIP if you needed rewriteable, and CD-ROM/CD-Rs if you needed software distribution and archiving.

I sold this rare disk drive on eBay for $799.95.

@@laurahoyer5457 They are rare, but, not as rare as the FD-4000. The FD-2000 drives should sell on eBay for $600 each.

Wow! 1.12K subscribers.
Congratulations! Near to reaching your goal...

Nice view of the insides! Great work!!
Thank you.

The rubber feet on mine turned to goo as well. The feet would stick the drive to the table.

Good suggestion, thanks.
Where does one buy Extended Density diskettes these days? I don't even remember seeing any in stores back when the FD-4000 was in production.

Has anyone made a clone of the CMD hard drive from modern off the shelf parts? I know the 1581 has been duplicated with new pcb and chips.

Too bad you sold it. Would have wanted the information to clone it

Fwiw it has the same PCB as the more common FD-2000. The only differences (I think) are the floppy controller chip, ROM and the floppy mech itself.
Cool. What is sector/track structure for high-density format?
The really insane thing about this device is that it supports ED (Extra/8x Density) floppies. Almost nothing used those, even on IBM PC clones, because other much larger formats were becoming available. e.g. LS120/ZIP if you needed rewriteable, and CD-ROM/CD-Rs if you needed software distribution and archiving.
Oh my God that was painful
