Subject: 1770 Disk Interface

Has anyone every tried to recreate a 1770 (or 1772) based disk interface
daughter board for the BBC Model B? i.e. make a PCB based on the schematic
shown at http://members.magnet.at/marku/bbc/hardware.htm Of course, this
assumes that a WD1770 or WD1772 FDC can be found.

I'd be interested in upgrade my 8271 based disk interface to the 1770. Also,
does the circuit remain the same for the WD1772 based interface?

If I get a positive response to this, my next question will be where to get
a WD1770/1772?

Chris.
