 from, they asked me to write an article about
extension GRMa. I am generally a person by natural
I'm lazy, so I hate to load isdos
and to write down, especially since half
until recently
There was no such moment . Well, first of all
a little lyrics.  I'll tell you about those computers
which I  had to use. Pro "Com-
panyon-1" I will modestly shut up, because nothing
I can’t say anything good about it except
that after his crash I was left with
a coffin like minitower, MS-5313 and cont-
roller flopNovosibirsk production
(and they say that VGshki do not work at 8 volts
they work, although I have worked for such a year
tal...). Due to delivery toBarnaulcompany
POV like "Synthesis-2", almost everyone I
I know there was or is this same Spectrum+,
ugh, "Synthesis." The car is not bad, it's a pity
only terriblybraking. Even those programs that
which onSkorpa do not slow down,can brake
go to Synthesis.ButThere are a LOT of synthesis!If
If the keyboard is loose, you can't get a new one
presented problems.  For example, I have
under the table in a suitcase there are four or
five boards. On Synthesis very well placed
320 lines, 128k based on slightly reworked
Leningrad expansion scheme,  and now
for half a year, Kruger costs 512 on cummax, and
nothing, it sucks.                            
                                          
   When I got the board Leningrad,
this epic with Syntheses is immediately con-
read. Typing some test for the number of clock cycles
from Reviews and seeing the result, and quietly said -
hall yes!, because it (quantity) was different from
pantygon for only 400 and kopecks. I love
I like to dig deeper into computers (by the way, this
image  Leningrad and burned),so my
there was a place for wild imagination to roam,
Lenigrad! As one person said: "to-
enough work to last a lifetime." As for life
I’m not sure, but after a month I was already normal
small not Leningrad with half a meter of memory. B
as a result of a successful experiment scheme of the
caught up to74200 cycles in int,and even
without  waita.  No extras like extras. re-
I didn’t do the gistrov like on Pentagon, just-
then I cut off wait from the processor... Why computer
earned it, I don’t know, but I didn’t mind.
By the way, God sent me one dayAndrey Panin
( DemoDED )  happiness in the form of  Pantygon.
Look for glitches on this... mmm... board I
didn’t take the risk, but was assured for a long time
baked with spare parts.  It is with Pantigona I
took off all the mikruhi except 5SSTL2, of which
soldered the mouse. However, let's return to Leningrad
du.                                       
                                          
   After the death of this coil inductance
I communized from Erasera his GRM, t. k.
This  bourgeois  bought himself Kai, and it was from him
peed in bed.  The only thing I need
managed to immediately do it on GRMke - this is ALMOST
Pentagon int,well and SounDrive with weather
tear off the roaring Leningrad. Simmasdo not want
whether to cling five months :( If I had
me  oscilloscope...  Well, I won’t
writeabout how I looked for this glitch on the
twice xeronic  "scheme",  fit
on sheet A4 (you have a diagram of the Pentagon
Can you imagine???),  but I still found it.
It turned out that the data register writes
data in the second half of the RAS cycle, and
Fast Page Mode SIMM outputs data in advance
howl. I had to cut off the road from D27/10.
After about a month I began to change the screw
twice the disks when copyingand I decided
puta meter for yourself, especially since you got it
yourself 38bSuX with meter symmetry. here me

I was waiting for the second bummer:  the sims didn't plow. Above
I struggled with these glitches much less (like
useful to look through the reference book!).  In general
failed 561st series, t. k. IE10 of this series
and at 15 volts the performance is not pleasing,
and on 5 and even more so. It is necessary to gate the outputs
this stupidity signal/CAS, otherwise 1mb
Sims do not like it when they row address in
read/write cycle change. Solder next
IR23,you bite off the board from 561IE10(A) no-
gi 3, 4, 5, 6, 11, 12, 13, 14,unfold
them, and go!A total of 16 wires,plus one
with it first leg IR23 sit on the ground, and on
11th serve  /CAS, for example with Z80: 6.
Expand across the Pentagon and stitch
TR-DOSS.13, service glitch.
