Just use softmpu with sbmidi mode. ENMPU.EXE never worked for me.

TLDR: A solder joint is broken under SMD resistor R68. I recently aquired a very dustySB16 CT1740. After some testing, it's apparent that the right FM channel is not working. Looks like other people have similar problems: https://www.vogons.org/viewtopic.php?f=62&t=90952 https://www.vogons.org/ …

My GA-6R7+ rev 1.1 has arrived. It can pass modulo 20 test on my unmodified board. I hooked up my oscilloscope to Vtt on the motherboard. It still goes down to 1.3V. Maybe something on this slotket make it draw less current than the other to not trigger over-current protection. To measure the lowest …

I see more like 2.5A at 40mA, just like mockingbird P2B 1.02 2SD1760 https://pl-1.org/getproductfile.axd?id=8364&filename=2SD1760.pdf If I understand correctly, the Collector to Emitter Voltage should …

That's very similar to 2SB1202, so the fix should apply. Though you should run memtest86+ first and check if GATE3 of HIP6019 is connected to the base leg of the transistor, which should be the rightmost one in my picture. Thanks... I confirm, GATE3 is indeed connected to that pin. I'm tempted to …

Wow, amazing! I have a P2B 1.02 with the HIP6019CB (which I plan to swap with the HIP6019BCB as soon as it arrives). My board has the 2SD1760 in that area, does the fix apply? Thanks 2SD1760-InchangeSemiconductor.pdf That's very similar to 2SB1202, so the fix should apply. Though you should run …

TLDR. Replace the 2SD1802 transistor near the cpu slot with a N-Channel MOSFET. photo1666612941.jpeg I recently built a 1Ghz coppermine machine with P2B v1.10 motherboard. The motherboard has an HIP6019BCB controller so it can supply the 1.75v volage needed by coppermine. I use a '370 CPU CARD REV …
