As I understand it, this is Delta-S 128? Where can I find a diagram for it and find out how?
connect the disk drive controller to the system connector, I want to connect a 3'5 flop,
and AU-8912 sound. And also, at b.p. the power bank burned out, or an analogue of the L7805CV, I would like
also a b.p. scheme find! Thanks everyone!

For appearance: Cheboksary Delta-S, 48K (8 pcs ru5d1(2) = 32K + 8 pcs ru6 =
16K)
The diagrams seem to have been floating around the forum, a description of the system connector is in
branded brochure, if the brochure is not available, then I’ll look in my own, I should

Hello jdigreze
I would appreciate a scan of the brochure! and another question, you can connect to the system connector
attach a veta disk? those. connect flop, sound?

possible. but it won’t be of much use at 48k

thank you!

The number of contacts in a two-row connector is indicated in brackets, without brackets - a three-row connector
(the middle row is usually pulled out)
There are also LPT signals there, but I don’t think they will be needed at the initial stage.

Hello jyly0s
jyl> thank you!
You're welcome... ;)
These signals should be enough to connect BDI, but AY8910(12) is better IMHO
insert inside the core...
By the way, regarding memory expansion: theoretically, you can carefully remove ru5 and
ru6, and plug in ru7 instead, add ports #1FFD and #7FFD, logic
switch, and get 256Kb like Scorpio-256... That is. if there is wild and
If you have an irresistible desire to upgrade, then you can experiment.
Hello jdigreze
in the brochure that came with my Delta, there was an error in the SX1 pinout
Hello fan
Atas, it seems that after the reset it goes back to BASIC, I already looked at your site for the upgrade, but
because I haven’t bought an LCD TV yet, and the encoder is incomplete, so I can’t say anything yet
:-)
Hello jyly0s
jyl> Kvanta BK
I wanted to ask - after resetting, does it go to BASIC or Tyrdos?
Are there any manuals?
Can you also click on the speaker on the board?
I advise you to leave the computer, because the design is good (if you rip out the power supply, then it’s small
flop guide will fit).
Here are the links that will help you with the upgrade.

upgrade 48k->128k (you can also see how it was done in ATAS256).

Hello jyly0s
In principle, if you are not afraid of a B&W image, then you can go straight to the composite
hem .
Hello fan
I forgot to mention one thing - the VIDEO signal (aka B&W composite) is hitting hard
stupid, for black and white it’s not so scary, but the PAL encoder will definitely be flattened. To the base
transyuk (from which VIDEO comes) you need to stick a couple of transyuks, 2 on the ground
(convenient to solder to the diode assembly and the RU5 leg) and one and a half kilos at +5
(relatively convenient to solder to the A6 resin assembly).
