I am not talking about the 8749 - but what Sinclair managed to make it
do.
You must have come across Hermes and the discussions of the naff
Sinclair code. 0.7 was an even more dodgy version.
They made it work badly, and Laurence Reeves, using exactly the same
hardware, proved it could be done well.
Pity he didn't work for Sinclair at the time.

Yes please. Issue 4 is the earliest I have seen.
Some description would be interesting too. Is it a full US version with
9D sockets and all the chokes etc.
