From Alexander Araktcheew To All 29 October 2000

Greetings, All! Has anyone tried to assemble Subj themselves? I mean, not on a finished board, but on a mole rat. And now I’m thinking of collecting something from nowhere) In order not to bother with the layout of the address/data buses, I decided to take a piece of the board Pentagon48, almost everything fits perfectly there. I decided to take the DAC block from SounDrive, Because it’s still almost idle. I have SD assembled using 1k and 2k resistors, so if you adjust the volume according to the following diagram: ┌──┬──┬──┐16 ┌───┤D0│ │Ro├─────────────┐ ├───┤D1│ │ │1 ┌─┬─┬─┐ │ ├───┤D2│ │I+├────O │ │ ├──┴──> ├───┤D3│ │ │2 │ │ │ │ ─┴─ │ │ │I-├──■─┤ │ │ │ D0t──┤D4│ │ │ │ └─┴─┴─┘ D1t──┤D5│ ├──┤3 │ K1401UD2 D2t──┤D6│ │GN├──┤ D3t──┤D7│ │ │ ─┴─ D4t──┤D8│ │Up├14───o +5V D5t──┤D9│ │Uo├15──┐ └──┴──┴──┘ │ + │ WITH DAC ───┤├────────┘ 10mk Will the volume be adjusted normally? All the best, All! Alexander aka Arc of RLDG.

Greetings, Dmitry! Fri 3 Nov 2000 at 17:39:55 Dmitry Lomov and Alexander Araktcheew were talking on the topic GS. DL>>> also, if your R-2R is not buffered, you will get DL>>> some DL>>> nonlinearity of regulation. AA>> Place an amplifier after the DAC? DL> is desirable. That's it.. The project has dried up at around 80%.. I sold my computer :'''( For only 900r :( Pentagon1024TurboHD+PCkey+KempstonMouse+SlotSystem+CMOS+Cashe64 kROMEmulate+AY+SounDrive+4WAmp+230WMiniTower+MPPS We'll drink a lot of vodka... And all because on December 1st I’m going to trample the year’s boots, presumably near Saratov. :( AA>> I decided to conduct experiments, so I didn’t notice any AA>> not AA>> linearity (a herd of bears and one elephant are probably to blame AA>> ;') DL> means it is small ;) So you don’t know yourself? ;) AA>> PS: Can’t you order bare boards there? DL> no. Abydna.. I'll give my imperfection to someone, maybe they can figure it out.. All the best, Dmitry! Alexander aka Arc of RLDG.

From Alexander Smirnov To All 21 January 2002

How are you, All? Maybe someone can tell me. My GS is giving me strange glitches. In this case, the program or hangs or continues to work without sound. I noticed that more often this occurs when both effects and music are involved. Maybe someone with this phenomenon Already encountered? Best regards, Alexander Smirnov.

From Nikolaj Amosov To All 23 August 2004

Greetings, All! Gentlemen, I am interested in the name of the amplifier microcircuit, which was in the first version of GS, which was connected via an adapter and required a separate 12V. [REAL ZX]
