Today I'll show you how to connect to your computer Kempston
Mouse Interface, described in the article (C) V. stalls "ZX
Spectrum and mouse from the 20 th spectrophone.
This will require a maximum of K555 (1533) LP8,
three resistor 1 kohm and a 560 Ohm.
Firstly the scheme of spectrophone need to add another small
piece:
+5 B LP8 / IORGCE Signals / BCS,
° ° / XCS, / YCS taken
March 2 with chips DD8
/ BCS D ° (LP8) Kempston Mo
A use Interface. Whitefish
° ° E signal / IORGCE in some
toryh computers
for example, SCORPION,
KAY, already implemented,
June 5th and if you PENTA / XCS D ° GON, we will
have

December 11 feet 20 processors
/ YCS D (signal / IORQ), it is necessary
13 necessary to cut and
° E gap solder resistor
torus 560 Ohm. Signal
up resistor remains unchanged / IORQ, but after
resistor, it will be / IORGCE. Can verify this by any means,
for example, tasted signals language. I assure you, will pinch
in different ways.
Making sure that you actually signal appeared / IORGCE,
safely connect it to the proposed shemke.
Second, you need to do this through a resistor
com apply +5 V to pins RIGHT B, LEFT B, MIDDLE
B.
Now connect to your interface passive
mouse or IBM-active-native, modified (or rather
vypotroshennuyu), as indicated in the ZX FORMAT # 5 and boldly
work.
Personally, I podlyuchal mouse so that's a way to PENTAGONu
and SCORPIONu and nothing happened, everything works. In the
newspaper there is a small testik, checking this device. If
needed, call ...
