Congratulations on the wonderful work. I wonder if it was possible to give this device the parallel connection with the RAM LINK; the same as the CMD hard drive. 👍🏻✨
I think if you tried to do this, you may run into a limitation of the data transfer speed of the FD. It would require a significant change to the original design as well.
Very Cool! I have a FireDrive2k that was a clone drive made some years back. I do have the RTC and I didn't know it was a dallas module. DS12887? That said Analog Devices owns the Dallas/Maxim RTC chip now since they bought the company back a few years back. They are being made today still probably because of the Industrial segmant. You can buy brand new DS12885 and DS12887 from Digi-Key, Mouser and even Amazon. I bought some a few weeks back and they were made in late 2023. I like your solution though it is much more compact.
Just when my retro collection is looking complete... along comes something else that I need! I'm thinking the FD-2000 will be more popular due to the relative scarcity of ED drives 🙂
I'm amazed at the stuff you put together and look forward to the next two videos. Are the components for this still generally available, or are there custom chips etc. that will be tough to source?
Thanks very much for your comment! You won't have long to wait for the next video. Yes, the components for the board are still very available. The BOM that I provide does include sources.
Thank-you for the comment. I will consider that, however, the reason behind requiring the PLCC socket is because it could be installed in the wrong orientation and it'd be a tough desolder for a builder if it went in wrong. Me doing it puts the owness on me to get that part right. My way of trying to help the builder where I can.
I always wanted an FD-4000... and I still do... but I've never even seen a single Extended Density disk - not even in the 1990s when these drives were still being sold new by CMD. Is it possible for such disks to ever be brought back into production?
Ouch. Sorry to hear that. Is that FD2000 clone you're mentioning one of those Firedrives? I've heard from others that they're real unforgiving on the input voltage. You're not the only one that I've heard with a burned up Firedrive. Thank-you for your comment. Much appreciated.
The VIA, from both MOS/CSG and second source suppliers that used the MOS die unaltered, has a nasty bug that stops the hardware shift feature from working reliably. This meant the VIA chip, unaided, would be unsuitable for the hardware accelerated fast serial modes (which includes burst mode). While the schematics for the FD series don't seem to be online or publicly available the schematics for the CMD-HD boards are. What CMD did to fix the VIA shift register bug is to employ a D-Flipflop (specifically a 74ls74 in the HD board). The Wikipedia page for the "MOS Technology 6522" explains this in the "Bugs" section and describes how a simple D-Flipflop can work-around the issue. Commodore could have done this with the 1571, but as it probably cost Commodore the same to make CIA chips internally as opposed to buying Flip-Flops from TI or whomever.
Is this the one you're talkin about? c256foenix.com/product/fnx1592hd/?v=796834e7a283 Appears to be perhaps an emulated version of the FD-2000 utilizing some sort of USB 1.44 FD as the mech if I'm reading it right. It's strange that they've changed the swap button to swap between partitions instead of swapping the device number. Swapping the device number like the original does seems to me to be the more useful feature, but to each his own. Kinda cool lookin drive none-the-less.
@@8BitResurgence The SWAP button works as in the FD2000. Sets 8,9 and returns to the original ID. Changes the address of other drives on Serial IEC. And brings it back. The description in the store is misleading. I have this drive with RTC and so far it is working fine. Floppy drive is NEC FD1238T. The electronics are based on FPGA
@@8BitResurgence Maybe I'll post some photos of this disk drive on Lemon64. I haven't seen any thread there about this drive, or about the previous one - fnx1591(clone of 1581).
Great work!
Another awesome accomplishment!
Thanks for watching the video, your comment is appreciated.
This is super exciting. Thanks for your reverse engineering efforts, the whole community will benefit.
Thank-you for your comment. Was such an exciting day, when my first board attempt sprang to life!
I like how you even went to the effort of using "CMD" IC's. Different CMD as I'm sure everyone is aware.
Hahaha... I was wondering if anyone was going to notice that. Goes to show people do look closely! Thanks for your comment.

thanks for all you do for the community
Thank-you for your kind words! Means a lot.
wow, great work! thanks so much for putting so much time into it to (re)create it for us! amazing
Thank-you for your comment, glad you liked it.
Simply amazing work. Reverse engineering and then feature enhancement and clean up. Thanks for all you do.
Thank-you for your comment! The added feature and cleanup felt like the right thing to do.
thanks for this amazing contribution! Can't wait to see the cases!
Thanks for your comment. Will be recording the case video in a couple days. Should be out soon.
Very nice - excellent work. Great video presentation… thank you for sharing.

Great work. Thank you so much for doing this project and showing us everything.
Was my pleasure. I had a lot of fun going through the process.

Thank-you for your comment. HD floppy drives are certainly more plentiful.
Great work !! Really want one to connect to my Mega65.
That would be a most excellent drive to have connected to your Mega65. Thanks for your comment!

If William Shatner is the greatest living Canadian, then you are the second.
Oh my gosh, that sure is high praise. Thanks so much!
@@8BitResurgence how much RAM can you put into one of those drives? Want to see co-processor options. I mean 2MHz is great; 4MHz is even better,
Cool project! Not that I need another FD drive but it would be a fun project to build one.
Thanks for your comment. Maybe make one for a buddy who can't solder. That way you get the fun and it doesn't add to the pile you already have! 🙂
@@8BitResurgence Will definitely build one sometime(tm).
Very cool!
What happened? Link to shop says "Product not found!"
Sorry, been working on the site. It's back again.
Really great work. Can you add the do not include CMDFD.PLCC socket option? It is missing.

So excited I burned up my clone FD2000 by pluging in 12v by mistake Still have it may be repaired?

@@8BitResurgence Yes need it experiment kind of a paper weight?
A project is never done!
Indeed, projects are rarely done. I've already received some recommendations that I'm considering.
Why is it that the 1571 and 1581 needed a CIA, but the FD-2000 supports burst modes with just a VIA?

@@pits645 oh, that's cool, I didn't realize there was a valid external fix for that. Thanks!
Recently, the FD2000 clone appeared. FNX1592HD from Phoenix Retro Systems.
30 pieces produced.
