Re: What would it take ?? USB to 1541 cable

I have talked with a few people the last 6 month's, and many are
faced with this problem now.... thier new computer has ONLY USB
ports, built into it ( like my new Dell ).... keyboards, mice,
and printers, all have to be USB.

Thats fine, for "PC" hardware.... but, I see no way in hell,
to create a cable, that can use a 1541 drive, for transfering
software to/from D64 format... on a UBS line.

I believe there are many general-purpose, programmable microcontrollers (or teeny processor cores) with the USB bus connectivity built-in, and which have a number of general-purpose, programmable I/O pins on the other side. Something like this, perhaps:

Someone should just tinker with those. Ideally, the USB device would handle the 1541 (Commodore serial bus) low-level timing and buffering by itself so that the file transfer program or a 1541 emulator running on the main PC would not need to do anything exactly in real-time (i.e. synchronously with the actual serial bus communications.)

(Requiring exact timing and synchronous operation from the PC itself, by making it handle all the serial bus communications and timing in a byte-by-byte fashion, does not go too well with the modern multitasking operating systems. Offloading these critical low-level communications tasks to the microcontroller of the USB device would probably make the whole thing much more robust, and much lighter for the host operating system to handle.)
