i guess you could have dumped the flash had you synced
your memory
accesses to the vertical interval?
Absolutely! I could have (and have done so for other programs).
But in this case,
1. I could not get the entire 4000 bytes in a single VBI
on the slower (4.77 MHz) machines.
2. I wanted absolute minimum resident size, since there was no
way to know ahead of time WHAT foreground programs would be run.
3. Once I told Sybex that it was the flash bulb, they were VERY
happy, since it provided a further visual confirmation that the
picture had been taken!
Also if memory serves you could have swapped the page
off visible,
copied it, and swapped it back and created quite a flash. lots of
opportunity for mischief.
At least one of the programs that they were trying to illustrate
was already messing with the RAM of other pages, so I thought that
it would be prudent to stand clear.
Hot Damn! I like sparkles.
