I've scratched my head a little bit and came up with revision 2.3: http://fotkidepo.ru/photo/229919/51603ZsCMjnrvd0/1017503.jpg Repositioned jumpers, added two more resistors and changed layout of SID clock selector jumpers. Also new silkscreen tips for SID clock and more tidy layout around 74HC192. …

Shouldn't it say : PCB & Layout Made in RUSSIA? :) Look somewhere around joystick port footprint... :lol: Aweosme stuff btw. I cant wait for some one to write an app to play SIDs in DOS. Yes, I'm also waiting for it. I'm also a programmer (C, C++ and many other languages) but never wrote something …

the 1818VG93 (clone of WDC1793) has a 2.5mm pin pitch rather than 2.54mm. Either way, thanks for making an international version. Yes, 2.5mm pitch was pretty common in USSR. maybe it would be better for the board to use for all logic the globally available 74series ICs instead of the Russian …

Finally, I have CD74HC192 in my hands. It works differently than K555IE6. :neutral: Currently with 555IE6 jumper selects frequency between 0.89 and 1.02 MHz, but with 74HC192 installed it transforms into 1.02/1.19 MHz. So when K555IE6 divides by 7 CD74HC192 divides by 6 and when K555IE6 divides by 8 …

Could you post a stacked price chart for the PCBs (1, 5-10, 20)? Maybe I could help out with finding a producer. Not exact numbers (and need to include currency conversion, all prices are initially in rubles), but something like this: 1 board ~ $59 5 boards ~ $84 ($16.6 per PCB) 10 boards ~ $114 ($ …

I've managed to write some marketing crap for the replica. :lol: Replica vs. original SSI-2001: + PCB is smaller + Fully manual PCB tracing: more accurate trace layout + Added extensive silkscreen onto PCB + Somewhat improved ground and power layout + Added ceramic caps for logic ICs across power …

More good news! MOS8580 works fine in the replica! Chip that I've got is certainly bad but replica has been tested with good chip and everything is fine. :cool: But I have something else to check. First, I'm still waiting for 74HC192 to arrive (terribly slow postal service). Second, I didn't check …

English subtitles for last video have been added. First melody you can hear there is russian band "Nautilus Pompilius" song "On the Shore of the Nameless River".

Good news! Again, with great help from borisfox I have patched scheme of the replica, and now it works well on every ISA-compatible machine (English subtitles will be added soon). :cool: Tested on: AMD Am386DX-40 @ Pine PT-321 Intel Pentium 233MMX @ Asus TX97-E AMD K6-2/500 @ LuckyStar 5MVP3 Intel …

I'll check out the comparision video about the machine speeds after the 6th, since I'm currently on a limited internet connection. There are downloadable .flac files, not videos. :happy: And glitches on faster PCs are all the same, no difference between different platforms. Replica works well only …

I wouldn't concentrate on the 555* vs. 74LS* issue too much. I think you are right, but I have to check it anyway to be certain. Have you checked if the 8580 works in a C64C? I've got this 8580 from other man in Russia and he told me that he pulled it from working C64. Maybe bad handling or static …

Incredible result there guys Thanks, but we do not have final result yet. There at least two problems: 1) replica doesn't work correctly on fast PCs 2) 8580 doesn't sound at all :neutral: I don't know if anyone outside Russia can download files below (because of cyrillic file names), but I'll …

I guess there is no Russian equivalent for the word "facepalm"? :P Well, there is, actually. Why? Cool card, I'm assuming Ultima VI's SSI soundtrack is identical to the C64 version. First, the C64 version has just one tune, which drones on endlessly. Second, the SID in the Innovation runs at a …

Hello everyone. I've found a technician who agreed to draw card scheme And this technician is me. :happy: We've got some more progress: I received factory PCBs for first batch. Now replica looks like this: http://fotkidepo.ru/photo/229919/51603ZsCMjnrvd0/1007819.jpg http://fotkidepo.ru/photo/229919/ …

Some examples of music played on SSI-2001 replica with this driver: ABBA - Money, money ABBA - Super trooper ABBA - Waterloo Aqua - My oh my Elvis Presley - Jailhouse rock Sting - Fields of gold The animals - House of the rising sun
