Dallas schemes are different
ZXNet echo conference «hardware.zx»
From Igor Turashev → To Viktor Vorobov 14 March 2000
┼┤e└└o, Viktor!
I also saw that Viktor Vorobov and All were talking
VV> to DALLAS connection
According to the glitch scheme, only a little tougher, it works for me and even works :) Catch it,
maybe it will be useful for someone else...

Here is a diagram for hooking up Dallas (imported kmos with
battery and quartz) by Arc/RDG. All you need is the floor
LL1 microcircuits, LE1 floor, or all LL1, but then just
outputs that were supposed to go from LE1 need to be set
inverters. If port #EFF7 is already ready, then there is nothing to do.
Otherwise, you also need TM8 and ID7, which are this very port and
form. Inside ID7, the most significant bytes of ports #XXF7 are placed,
which I remember. Small logic circuits can also be supplied in the 555 series,
but 1533 is still better.

Leg 20 and 22 in Dallas may not be (as in me), then
цепляйте резюк на существующие (maybe, in whom others are not). Ashley
часики будут глюкать, то можно попробовать посадить на 18 ногуthe air conditioner is around 18nF to ground, but if there are still glitches,
you can try to plant Dalas's first leg on the ground or at +5
through a summary (where to plant is determined by scientific poking).
Signals from legs 2 and 3 of TM8 can be supplied to the circuit
additional graphics mode 512*192pix. Then all that remains from that scheme is
KP11 (or KP16) and IR23. Accordingly, from leg 10 you can serve
to the GIGASCREEN circuit, from which KP11 (or KP16) will remain, floor
TM2 and one element LA5.
All this garbage works fine for me, but the circuit was
redrawn for Dallas from VI1 connection diagram by Roman
Milukov. Redrawn - Tigrr/BW, figured out how to pick up
Dallas - Arc/RDG.
