  In our new section today you will find
memory expansion scheme "Byte" up to 256 KB.
The circuit was developed by Sergey from Kob-
Rina. Its coordinates: Kobrin, Brest
region, st. Dzerzhinsky, 79 - 24. Phone:
(01642)2-09-17.
 The scheme is simple, tested on several
machines. The results are only positive!
Yes, the 48th users are out of luck, the schemes are in the 48th
there will be no mode. Hence the output: ZX-128(256;)
Rulezzzzzz!




















 1. It is necessary to solder the pins of 16 KP565
PY5 to the computer as fast memory, except
CAS output, which is combined into two
groups and connects to CAS D' and CAS D''
(see diagram).
 2. Tear off the 7th pin DD1' (TM9) from the 11th
terminals DD8' (LN1) and DD2' (KP11) (see diagram
mu expansion up to 128, developed by all those
or Sergei. The diagram can be ordered from the editor-
tion) and connect to T1.  To T2 - via in-
vertor Q6, to T3-11th pins DD8' and DD2'.
 3. 8th pin D15.3 (see “Byte” diagram)
solder - this is CAS H. CAS H'-is served in-
then the old CAS.
