Hi,
In the process of clearing out my lab here at the University of Essex, 
I've come across a '68K/OS Systems Programmers Reference Manual'.
The document is around 65 pages long and I have some recollection at 
the time an NDA was signed, but maybe that was due to some sort of 
testing. I joined the uni around 1985,at which point there was a QL 
lab with around 30 QL's all with a ribbon cable leading to a 3U rack. 
The rack had memory expansion, serial ports, parallel port, GPIO ports 
and floppy disk interface.

Re: [Ql-Users] Lear PCB Design v7.55

Hi Michael,
FreeRotate is just experimental work in progress. It may be better to 
leave the coordinates untouched and store a one byte rotation value for 
each element, thus allowing accurate return to zero degrees if required.
