ZXNet echo conference «real.speccy»
Hello, All!
Sunday 3 Jun 2001 06:17:27, Eugene Palenock -> Dmitriy Nesmachny:
DN>> could you describe to me which ports are decrypted by ID7 by
DN>> GLUK's standard
DN>> are they used for something and for what specifically?
EP> dff7, bff7 - clock;
EP> eff7 - configuration management (512*192 (D0), turbo,
EP> gigascreen, dos-direct, clip 128k, rom-disk, clock on
EP> (D7), multicolor (D1));
EP> cff7 - in some service firmware enabled. in
EP> real.speccy ask
People, pls, tell me which ports from ID7 from under the Gluck clock are already
standardly used for different devices?
Sincerely, Dmitriy.

In general, here it is:
eff7 - 0 - screen 256*192, attribute per byte.
1 - screen 512*192, monochrome. In some
schemes it is colored in the color of the border.
2 - blocking RAM above 128k via 7ffd.
3 - turbo
4 - gigascreen (hardware screens 5 and 7 blink)
5 - enabling DOS ports
6 - connecting another ROM (ROM-Disk)
7 - allowing work with clock ports (the old way
scheme, according to a new one are always available)
8ff7, 9ff7 - RS232 invented by someone.
dff7, bff7 - clock
aff7 - 4MB RAM disk or something else.
cff7 - if the cache is 32k, then you can turn it on in different ways
- as a cache, as a pseudo-ROM of DOS and
BASE, etc. Someone else here put buttons
configurations like some kind
fff7 - it seems to be free, but it seems in some zx here the memory
was switched (albeit in the DSA space)...
eff7:2 and :3 can be used for completely different purposes.
Sincerely, Evgeniy.
