I will look into that, thanks.

As an aside, I now have a working EPROM programmer so have burn't RP/M 2.3 with divisor for a 9600 baud serial port. This works well, next I will patch CP/M for 9600 also to make a more useable system all round. Alas, I still don't have a working IVC card. However, I will send Barbara out shopping and try and spend some time looking at it tomorrow.
