Did everyone notice this? The board looks a bit big, with no
surface-mounted components, and I think the ATmega103 would provide an
almost single-chip solution, even with a built-in real-time clock.

I have finally finished my hard drive controller for the commodore
8-bit computers.
It enables commodore computers with an IEC serial port (VIC-20, C-64,
C-128) to connect to standard ATA hard drives.
There exists several hard drive controllers for commodore computers.
This is what is special with this one:
- Uses the serial port.
- It works just like a 1541 disk drive, so no driver software is
required on the computer.
- Works on all computers with a serial port
- Supports subdirectories
- Only one large partition (supports up to 128 GB disks)
- Due to the slow serial interface, it is quite slow. But
still significantly faster than the 1541.
- It is free! (GNU software, public domain hardware schematics)
You can find all schematics and source code on my web-page:
http://www.stud.ntnu.no/~djupdal/cbm/iecata/
I don't expect anybody to actually build this thing, but I hope the
schematics and source code will be of interest to other computer
hobbyists.
