Like 74LS670? 4*4*4 is 64 while SAM have 69 keys.
What do you want to do with Spectrum programs that test keyboard
with 0 in high byte?

I think using 74LS148 or 74LS147 could reduce 9 columns to 4
wires. And 2 more must be added as power for decoders.
This gives 14.
The 8 rows can be coded by 74LS151 and decoded by 74LS2

Did you use microcontroller (which one?) or EPROM matrix?
I'm thinking about connecting PCKBD to the MIDI IN/OUT. It
should work at least with my CP/M.

It looks like ATOM is internal inteface. No

Hi!
Does anyone have SAM in PC cover? I'm going to do such removal.

Hi!
I only want to add that in my operating system called ZXVGS
the ".Z80" snaps can be loaded by RSX. There's only need to
copy them to CP/M disk.

Hi!
I made demo version of my CP/M 2.2 QED. If anyone wanted
to test it please let me know. I can also post it here.
It is 20KB long in uuencode. The basic knowledle of CP/M
is needed because there are no docs included.

Dzieńdobry!
Looking at those quarrels I made little summary:
There are two HD interfaces (not including my inventinon) - SD
and Atom. Atom is better and can be used without HD drive.
My questions:
Are they compatibile? What has Atom apart from HD controller?
Eg. own ROM, DMA, 1.8MB floppy c
Hello!
I am SAM user since 1991. I'm now not up to date about SAM. I
want to ask some questions.
How many SAM users have hard disk (except me)?
Is there any operating system that supports hard disk?
I saw SAMDOS, MasterDOS and PRODOS. Are there more of them?
I want spread my programs (they are
