ASSEBLER NEED, PROGRAMMING VG93, ZX-NET & etc.

People, does anyone have an assembler that allows you to load a program in code (not special text-assembler), view it in assembler mnemonics, make changes, insertions (in this case, the transition addresses change accordingly), run step by step - debug, write in codes, works with decimal constants, it is possible to print the text of the program on a printer in a convenient form. If anyone has something similar that
would work on the ZX-SPECTRUM 48k, please share.
I am also interested in a convenient text editor that has character encoding like
on IBM, it is desirable that 64 characters fit on the screen per line, with unlimited or large length lines (at least more than 80 characters), preferably the presence of a hyphen, etc. functions.
Does anyone have any information about programming the VG93 disk drive controller (port addresses, control commands, etc.) --- please tell us.
I am also interested in a program that allows you to format in any format (any
number sectors, their size, etc.).
Who knows if there is any network for ZX in Kyiv (I really want to).

I apologize if I wrote something wrong, I just managed to subscribe to
echo, which I have been dreaming about for a long time, I have not yet had time to familiarize myself with its rules.

Sincerely,
Friday October 31, 1997 Denis.
