Bottle rosin - The controller for BZ128 Computer "Byte".

                      BOTTLE OF ROSIN :-)


                                                           DELTA

                   Controller BZ128 (bytes).

    Controller by the way is quite steep, have an inner
printing in multiple layers, high density circuits, the elements
expansion komputera to 128K, music and math coprocessor
interface LPRINT III.

 First and foremost, a system connector for him:

1. DATA 0
2. DATA 1
3. DATA 2
4. DATA 3
5. DATA 4
6. DATA 5
7. DATA 6
8. DATA 7
9. STROBE
10.BUSY
11.OV
12.OV
13.OV
14.OV
15.Kanaly AC.
16.Kanaly BC.
17.MAGIC
18.MAGIC


    + For "MAGIC" to connect the 17 and 18 contacts.

    + Wiring "muzykalki" improved compared to
See previous file models, now it does not litter on the data 
bus. 

    + Stereo ACB.


    If you want something to muzykalka you have played, and the 
dynamics of and amps. Then take two 1k cutter, and do so

scheme:



   15


   16


      Free contact connector, I HAVE SUCH B16


   Locate the bottom row of "byte", such a combination of 
cutters (left from RU'shek). And napravte the whole thing on 
the R44 (the amplifier UD2). 


                     B16 (in komputere)



                R44


                R45



                 O



   Here is the text of expansion up to 128K.


    1.If you have the D51-D60 KR565RU5D1, D2 (halves)
they must vypayat and replace RU5B, C, D.

    2.OZU D43-D50 KR565RU6 vypayat and replace them with RU5, 
and 9-pin no solder, and lift up, join together and

connected to the ninth conclusion D41.Polovinka this chip
free, why deploy the it. 13 output is connected to +5 V, 15
output to the total. The remaining conclusions of this chip is 
connected to table.


    3. Vypayat and lift your feet the following chips: 13 and 
14, D56; 8 D15; 2 D21. All raised output is connected according 
tablitse. 

    4.Pereklyuchatel the board set to X1.

    By the way, if you have no wiring diagram "byte", and you 
do not know where there are located raznyy D21, D56, etc. 
Please call me and I've found perekachayuvam WORD'ovsky with 
it. Since by horizontally, it takes about 200 characters, then 
posting it become unrealistic.
