Two small protsedurki.
Now about the issue, which
has been raised repeatedly in the pages of ZX-Revue.
STANDARDIZATION. All correspondents offer (in
Basically all) to standardize
our good old SPECCY, system connector, Kempston, co-processor,
etc. etc. Gentlemen, at this stage it is unreal!
Look how many species we have the Spectrum will not be
mistaken if we call the number 30 or 40. And to hope that
users of these computers
abandon them in favor of standardized offspring, which we
propose to have a joint effort at as unreasonable.
My proposal is as follows. Must
make custom programs
and not alter them at the computer. That is, in the software
itself installs the module is located (or the whole program is
a preference), which during the initial startup requests
configuration data computer or keeps track of the
automatically. Then, create a working version of the program. So
properly solved two problems: the question of compatibility and
the issue of illegal copying.
Since after the program settings on your computer and
destruction of the installing the module program is unlikely to
work on another computer.
Ca. Ed.: Good, but not a new idea.
Look at programs such as Alasm
v3.5. There's a compatibility issue solved easier than the
suggested Denis, but the system drivers more flexible. Thus,
the users' best interests, even very specific (rare) computers.
After anyone can write drayverok for themselves.
Now imagine if this task
