Seems to work a treat. I shall no doubt feature a bordertron generated pause
effect in my next game.
Many thanks for your work on this, Chris.
All the best
Andrew

Subject: Re: BorderTron 3000 - SAM Coupe Edition
New binaries (v1.02) at http://freestuff.grok.co.uk/bordertron3000/sam/
I've taken Si's comments on board regarding the visible display area,
and reduced the width accordingly. Also added registration marks to
show the position of the PAPER area and the limit of the TV-visible
region (have left an extra 16 pixels either side of the visible region
as this allows you extend a 3 character block of colour into the
visible area to shift a scanline right by 1 single character, IYSWIM).
Also, fixed the various MacOS bugs (I hope...), fixed the Z80
interrupt re-entrancy issue, and improved the quality of the code it
generates a bit.
Full source code is available here:-
http://freestuff.grok.co.uk/bordertron3000/sam/BorderTronSAMSource.zip
The bulk of the source is actually the Z80 assembler. The UI, DSK
output, and border-related stuff is pretty small. Am happy to help out
if anyone wants to reuse the code.
Cheers,
Chris.
