I recently acquired a brand new CMD FD-4000 reproduction licensed for production by COREi64 (www.corei64.com). In this video I take the screws out of the case and give you a little tour of what it looks like inside.
I've never owned an original FD-2000 or 4000, but my understanding is that the board layout has been updated. And the case is new 3D-printed design that I'm sure has some differences that are probably interesting to see. All in all, I think it's a fantastic design. And I couldn't be happier with it.

Nice video. Enjoyed watching it. Glad you like my case design. Probably my favorite design I've ever done. The metal threaded things in the plastic are called "heatsets" and they're made of brass. The front panel of the case slots in exactly the same way as the back does. The reason it's a little tighter is because there's a bit more material that goes into the slot, plus I made the tolerance a little tighter on the front panel because I never expected it to be removed. Whereas the back panel I did expect it to be removed and replaced from time to time. The drive mechanism, as actually new old stock. Each FD-4000 that I sell gets a brand new, never before used drive. In fact, all of the components on the PCB are either new or NOS parts. The wires that power the drive and lead to the switch are silicon sheathed wire with very fine strands. I chose this wire because I expect users to go into the drive from time to time, and didn't want the wiring to ever break. This type of wire is very resistant to breaking and wear. When I created this drive, I created it to last. I hope you have many many years of enjoyment! COREi64

Thank you for those clarifications. And thanks also for the amazing work you're doing, I hope every Commodore 8-bit fan on Earth takes advantage of what you're building over there at COREi64!

Congrats on taking the FD-4000. The missing square chip is the one used in the FD-2000 instead of the larger one used in the FD-4000. In the latest revision the RTC is included with the motherboard. I guess using this drive for demos would be more useful than the 1541... 4 MHz ... 😁👍🏻

All correct on the missing square chip. The other major difference between the FD-2000 and the FD-4000, as you suggested, is the CPU on an FD-2000 is a 2Mhz 65C02 whereas the FD-4000 uses a 4MHz 64C02. The jumper block beside the 34p ribbon cable exists for configuring the PCB to either FD-4000 or FD-2000 mode. And I decided to go back to the cleaned and re-routed non-integrated RTC PCB for all builds because I decided that I didn't want SMD parts on the board from a maintenance perspective. Although it initially was a fun idea to integrated it, I ultimately wanted it to be completely serviceable (with it being entirely socketed) and more in line with the original design concept.

@@8BitResurgence Thank you for the clarification. I have to say that I agree with the decision to stay closer to the original. ✨👍🏻

@@8BitResurgence Ahh... the RTC board has an SMD component... yes, clever idea to make it a module, socketed and serviceable. All around, fantastic work.
