Subject: Hard Drives

Hi!

I've just been looking at the old messages to the mailing list, the ones
from about 1992 or thereabouts, and I have been reading a lot of messages
about someone who produced an SCSI controller board for the BBC, so that
any SCSI device could be connected, the total cost then was about £35, so
it should have fallen a bit by now.

Anyway, I was wondering, is anyone still on here that knows how to make/has
a controller board for the BBC, and if so what drives are compatible?

I have a big PC power supply, which I ripped out of a broken computer, and
then laughed heartily at how my 10 year old beeb could out last a 4 year
old pc! This I use to connect 2 80t double sided drives, and could use to
power a hard disk, so all I need is the board, a 1770 controller, an SCSI
controller, ADFS, and some money - is this correct?

Also, I want to add two 3 1/2 inch drives to the beeb, will it work with
1.44mb drives in 720k mode?  My ultimate aim is to have 2 3 1/2 inch
drives, and then one 5 1/4 inch drive to run the old software which can't
be copied.  Can I add three drives in to the beeb, which can be used at the
same time?  Or do I have to add in a selector switch to add in the 5 1/4
inch drive at the expense of one of the 3 1/2 inch drives, so I could
either have 1 3 1/2 inch, and 1 5 1/4 inch drive, or two 3 1/2 inch drives.
 Can someone help me with this?

One last thing - does anyone have the information to build the Micro User
real time clock? A scanned copy would do, the article is in the Feb 1984
Micro user if anyone has got that.

Thanks!


See ya!
