Hello :)

The apartment itself rulny:)) Muzychka good article great, and 
most importantly useful and smart:))


Red> thanks for the music again, kyv'u and c-jeff'u;)

Should be a little rastroit .. although personally I would be 
happy because better in time corrected bug than aspiring to a 
glitch:) 

Red> bugs, glitches, bugs ... nowhere to get away from them;)

1. Nelyubov turbo mode. When run on Scorpion (tried to emulsion
Z80Steals and at its realnike) after printing the entry and
Blink border hangs on a series of HALT'ov # 8259 - # 825E.
The first time hovered at Hult with prohibited interruption, on 
the second start interrupt is permitted, but for some reason 
obsessed with this site Halt ..: If you disable the turbo mode, 
it works fine, and the right on the move .. that is - hanging. 
turning off the turbo. continues normal operations. 

Red> yes ... it already looks like a hardware problem. The fact 
is that the intro course is tied to one of the channels 
AY-chip, and the turbo apparently incorrect information can be 
read (should probably do pause between the installation of the 
chip registers and reading from it, please, who has some 
information about it, Please send, or even write on this 
subject in a newspaper article). In entom room will fix the 
number 2, which will make it possible to load the room (+ can 
be poskipat intro, so as to any fireman;)).


2. Glitch with the text to scroll, found in the article about 
Chrome. Article by the way great! Concise and informative:)


are Gluck:
open article
button to the bottom line
then one line up
then down
Then Enter ...
will be the beginning of the article and all .. visyak.

Ed> by repeating these actions, a glitch has not shown itself, 
but This bug is known for even the mechanism of its occurrence, 
but He was not corrected due to lack of time, (


With this garbage came across, if you press down on the page -
(Number of first line of text on the next screen, plus the 
number of lines fit on the screen) more than the total number 
of rows fit on the screen

to withdraw the remainder of the text block and page down 
button,  in this case, the procedure "line-up is necessary to 
wait until text does not reach the end of the screen

(The first line of printed text lines + remainder before the 
end of text) is greater than the number of lines on the screen

and only unlock "page down"

Ed> I uchtu all requests (but not bug because of this;))

3. Do not bug itself, but on a computer with an unstable bus
neudastsya run, or will ever fly. Horoshoby
interrupt vector table vsetki razvarachivat fully and
fill in one byte. Memory is finite sorry, but reliable and
 is considered good form:).

Red> Interesting point, with the pilot forgetting to make the 
plate numbers;) 

On the whole room went intersnyh and cheerful, pleasant
read:)))

Red> thanks a lot Trident.

Hello, Dmitry!
Newspaper ZX Ferrum # 02 does not work in the emulator Shalaev:
after passing through the screen saver "2024-year" - visets.
On standing beside 'Pentagon 128' with the same distribution, 
"all Ok. 

Red> Sadly, but this is probably the fact the emulator Shalaev
it freezes, and apparently on the same chain Hult. Just want to 
say about the emulators - I do not intend fixed under emulators 
shell, but in this case bug manifests itself in the actual comp.


P. S. Glitches in listalke nailed (forgotten there were three 
teams DEC, now And so, in the life of + / -1 value is small, 
but in the program mation of a huge. Just a little bit faster 
listalka and removed on FIG pointer position in the article. Go 
to the next number will try to make a new listalku ...
