Subject: disk controller info

hii

Does anyone have info on the 8271 and 1770 disk controllers?  I'm looking
for things such as pin outs, and other general data on the controllers.

Is there any difference between the 1770 and 1771 controllers?

Also, does anyone have a circuit diagram of the 1770 disk controller board,
or has one? Can someone tell me what is on the board?

Also, on a similar line, would it be possible to use the 37C65 disk
controller in the BBC, with modifications, so that high density writing is
possible, up to 1.44mb on 3 1/2 inch drives?  I know this would require a
re-write of the filing system, but could it be done?

thanks


See ya!
