But before I burn time and money on this I was wondering if anyone has any thoughts whether this is at all feasible. Is the above board enough beefy enough to communicate with chips at 10ns precision? Or do I need something even better? Hi, i didn’t deal with this Atmel Cortex-M3 microcontroller, …

Do you know if the original owner posted about this last week? I saw a similar message but by the time I tried to reply I couldn't find the thread, maybe the post was deleted? Hi, I have not seen his posts on this forum. He created the topic in a Russian-language forum about the problem. I checked …

Hello, Recently i pickup de-CQMed CT2950, but the previous owner removed the YMF289 chip from it because he couldn’t make the FM sound work. He attached original CQM and TDA to complete. So, i want restore CT2950 to original state. I soldered back CQM, TDA, resistors, but i need help with identify …

Some caps (2x) and a diode are highly recommended, as it seems. Caps - yes, recomended, especially on the output, something like 10uF + 0.1uF ceramic + 0.01uF ceramic . Diode - i think no, its short-circuit reinsurance in very old 7805 regulators with high unstable power source like AC/AC …

Yes, the card is extremely noisy. That's one big drawback. Yes, SAA1099 has open-collector outputs which we pull-up to +5V power rail with 1K resistors and collect all the interference and digital noise from all computer. In my CMS-clone design i modified circuit, i make new "analog" +5V path with …

You can try to short circuit this inductance (L): Filename riva.jpg File size 164.48 KiB Views 220 views I indicated the purpose of the inductances approximately. First of all, you need short circuit HSync and Vsync inductance. And if i not mistake, short GND inductance. Maybe this will help.

By the way, I compiled the soft-fp library from gclibc sources with help DJGPP. I used VirtualPC with Windows 98 environment for long files names. I took sfp-machine.h from \gclib\sysdeps\x86\fpu, included in soft-fp.h. strong_alias everyvere in *.c files, so I added to softp-fp.h this macro: /* …

kixs, not bad. You can compare this result with attachment EXE file - its compiled with FPU-optimized asssembler functions with DJGPP 2.05, GCC 9.2.0, with CFLAGS=-O9 -march=i586 -Wall -fomit-frame-pointer -ffast-math

I am disable definition in quakedef.h and quakeasm.h #define id386 1 (set it to #define id386 0), thus, all assembler FPU optimized procedures are replaced by C-functions. Unfortunately, DJGPP have not build in soft-fp …
