   Well, that has come, finally, the time to increase the 
amount of RAM on SPECCY option Taganrog 128K! Now many owners 
These masterpieces of technical ideas can easily get dusty 
soldering and collect the wiring diagram of 30-pin SIMMa. SIMM 
1MB needed, but especially want to you can raise and 4MB. What 
does the "process of enlargement? All very simple: first 
vyderbanivaete with motherboards K565RU5 then dopaivaetsya five 
chips: 

K1533AP6, K1533KP16, K1533KP12, K1533ID7
K1533TM9.


(Of course everything can be 555 series), then
cuts a few wires, make
a few jumpers, buy yourself for 3
penny old zanyuhannuyu 386SuX33, fed to gently suction 30 pin 
socket (and I myself bought a socket for 3 rubles) sawing it 
into two parts fret (ie because they are dual) and attach this 
socket where you were RU5. Connecting

Again, the cables to the board, smash
himself SIMM, turn, and it all again - and earned a 
half-oborota.Posle that you have all your pets, ugh, it's same 
PiSyuk me something translated, but in fact you have a Pentagon 
512K, Profi 1M with the ability to toggle off the entire

upper memory, lest, God forbid not go
any KILO-, MEGA-, GIGADEMO. To celebrate you give the remaining 
half of connectors to a friend, and he repeats the same 
operation, and you still get an additional opportunity to get a 
lot of fun, scratched all three rubles. From there you can 
remove the following valuable items: battery, remaining twin 
socket for SIMM (that to sell it to another friend), a chip

hours (it should be near the battery) quartz at 32768Gts (for 
hours, and it is located next to mikroshemkoy), ROM (if you're 
lucky, she UV erasure, but usually disposable, and it can be 
thrown out), a bunch of small capacitors 10 uF, a crowd of 
switches and a bunch of ISA - slots. Also meet the foreign 
analogues AP5, AP6 (see by directory), the resistive matrix, 
well for special sadist - the processor, which can be stepped 
on, spit roast on low heat, dipped in a jar with

sulfuric acid, tear off all the legs and wash
the toilet. Then:


        LD BC, # FFFF
M1: Wash hands thoroughly

        DEC BC

        LD A, B

        OR C

        JR NZ, M1



   And finally, you can sit down SPECCY 1M. Fuh, all this 
expansion. 

   Memory test can be done reworked me HONEY TEST. Definition 
of upper memory is done automatically. The test is good because 
it has a bunch of settings and validation of regeneration, but 
it's quite a lengthy process: a full scan takes about half an 
hour, and without checking the regeneration slightly more than 
3 minutes (data are given for the test 1 MB). Should not only 
pay attention to the fact that the test you have found 
expansion of the ATM-TURBO. If modifications are made, I simply 
forgot about these inscriptions. By the way, if you want to own 
more and ATM'ovskoe extension, then need only one more switch 
to the first leg of ID7 (A9-A13). 

   Well, the meter is, but what if you want more? And not just 
more and more than most tricked PENTIUM II or

MERCED. Let us not think, and whether we should
do so much? The issue is that any
clear: to expand the Pentagon
512K - this is the limit, according to PROFI picture slightly
another: now uses bits 0,1,2 port # DFFD, so it remains only
Bit 3, because the fourth is used in the PROFI
for CP / M. Hence the conclusion: 2-meter-limit
This portu.A now I would like to offer 2 options:

1) Recognize that PROFI not such a common car and use the 
remaining bits, then get a maximum of 32 meters. -Lack of 
disgruntled users PROFI; 

2) Put in addition another port (which
namely, should be discussed with the coders, zhelezyachnikami), 
then get 512 MB. The disadvantage of this - already involved in 
the switch 3 port.



   I suggest to discuss-the topic, can anyone have any new 
proposals. 

   Now for those owners of Taganrog 128
1M, which have such a cool thing,
as a ROM-DISK. As far as I know, in Rostov
dominates the oldest model of this stuff, which crawls very few 
programs. Well, I can only posochuvstovat and

to say that I have are two ROM 27010 (in
amount of 256K) +2 RAM 62,010 (in total more
256K). The catalog contains more than 100 programs (mainly the 
system, since they are most needed, takes up less space and 
more useful games). We tried to redo everything new, noteworthy 
programs, so that their Number is steadily increasing. I now 
sewn 16 programs (+ RAM DISK 20 program). Among them Alasm 4. 
1, STS 5. 1, Real Comander 1. 6, Best Viewer 2. 4 (a

2.6, but it does not go to the ROM 91-year), RDS
3. 1, text, graphics, music
processors, packers, Tetyais 2, Chess. Well,
like more and should not be. I want to say that
by ROM-DISK speed and ease of use is much higher than the 
floppy. 

   I would also like to say a few words
the prices of SIMMs: as I wrote, the twin socket I bought from 
us at the radio market for 3 rubles, strap yourself in the 1 Mb 
range from 25 to 40 rubles, depending who you ask.

In Rostov, like higher prices (I was there in
early February and a strap was worth 50p.). Nurse have 60-70 
rubles (SX33). There is 2 double sockets, if cut, then

it is already possible to extend 4 SPECCY.

   By the way, almost no difference that the hitch.
If you wish, then send us SIMMs 72
pin, DIMM'y because SPECCY all hawala.

   If you have any questions, comments, suggestions, impulses 
to help in the form of SIMM, DIMM, programs under the ROM-DISK 
(can be in the form cracked the code of the program (s) block

(S), please contact me, that is,

   P. S. Our group works, I was finishing
music editor, there are lots of ideas and
algorithms to implement the tough editor
samples.
