Brunword MK4 (ROM)

BTW, The "version" number that shows (e.g. RW383... perhaps this is actually a digital signature for the person who bought it - this is speculation btw).

Richard Wilson, copy #383?

I looked at the Brunword documentation and it mentions that the 8-bit printer status port is supported by Brunword elite.
So I downloaded that from cpc-power.

And yes, there is some special code in there.

A normal PC printer port has these statuses:
- Busy
- Ack
- paper empty
- select
- error
- irq

Brunword elite has text in it for Paper, On/Off Line.

It writes to the printer i/o port, and then reads from the busy.
Bit 2 and 1 are used and are turned on/off.
Not sure yet what is happening, but I think it's reading the status from the printer.
Can't yet see where it does 8 bit printing yet.
So this thing is quite sophisticated.
Unfortunately, my initial attempts to test didn't bring anything up, and I did a write to the port and read back.

I'll keep looking at this Brunword code.
