Dear N!
1. Well, for starters, I can say,what are you
are not alone in their attempts. It wouldn't be that way
there was a great misfortune, but it is spent irreparably
The most complete resource is time.
2. Now about the clock generator.
See the rectangle at the clock output
generator is impossible, because requires special
cial oscilloscope. Overwhelming pain
Most oscilloscopes have a limited bandwidth
lowered by 20 MHz. In addition, on
such high frequencies require consistent
signal circuit at the oscilloscope input
fa / output of the circuit under test. Otherwise myself
the measuring device will be its probe
introduce distortion (bounce of a long line).
So even if there is a rectangle there
(which is not a fact yet) - You still don’t
you'll see. In addition, the clock circuit
Pentagon's one of its weak points. There
requires a set of strictly defined schemes
(series) - otherwise it doesn't work.
3. I cannot guarantee you that with
KAY won't have any problems at all. How do you say
It’s good to wander where we are not. But, probably
Of course, there will still be fewer problems, and,
additives, they will be solved.
4. Regarding connecting the printer. Vop-
grew up in "Open Letters" was already asked by RA-
FOR THREE. I quote the "User Manual"
la", page 9:
4.1. To use the printer you must have
IC AY8910 installed (supplied with
ki is not included, if necessary, pays -
sold separately - see price list).
4.2. "... The printer must respond as follows
blowingrequirements:
1. Support Centronics interface,
presence of a standard connector
(DV-25 R /DV-25S)
2. Encoding of control characters by
Epson specifications
3. Cyrillic character encoding according to
KOI-8
Compliance with requirement 1 is necessary in
anyway. Failure to comply with requirement 2
leads to the impossibility of printing graphic
ki, and failure to comply with requirement 3 will not allow
lit to print the Cyrillic alphabet using the built-in
new ROM. Limitations 2 and 3 can be circumvented by
using special drivers,
working in the ID-DOS environment. Actually,
to find out, you can order the "Manual"
user manual" (see clause 2.4.

5. Do you have a representative in your region?
