Subject: [BBC-Micro] Watford Co-pro adaptor
Another thing that's just turned up on the doorstep... a Watford
Electronics coprocessor adaptor.
Never heard of one before - it has a nice metal case with a hinged lid.
Inside is a 80186 board which appears to be the same as that in the Master
512; this plugs into a board that has a trailing IDC cable that I assume
plugs into the Tube on a BBC.
I'm assuming the unit allows Master copro boards to be used on a regular
BBC? In which case, do I need anything special on the BBC side software or
hardware wise to make use of the thing? The user-added label on the case
says to switch on the adapter, then the computer, hit ctrl-A-break, and
after the drive spins to insert the boot disk (which I don't have)
Oh, the unit also has a power switch on the front and a latching switch
with an LED above; due to the latching this presumably isn't a reset -
anyone know what it does?
As an aside, what copro units were produced for the Master series? I only
have the one 80186 board (well, two now), and a few 65C102 boards. Were
there others as there were for the BBC - Z80, 68000, 32016, ARM etc.?
cheers
Jules
ps. I have no idea why they went to the trouble of nicely hinging the case
- I can't see people wanting to swap boards in the unit *that* often!
(unless it has a habit of blowing them up :-)

80186 requirements are similar to those of a BBC Master, you'll need 1770
controller in the BBC and DFS and ADFS.
You'll also need the DOS PLUS BOOT DISCS and GEM SOFTWARE.
