Is it certain the card needs a recap? If it doesn't have any issues then there is no need to recap it since Roland used good caps. If you do need to recap then get some quality ones like panasonic/nichicon/rubycon/chemicon from a good vendor. There are a couple of bipolar caps IIRC on it so the …

^ Well said, both posts. The same propaganda BS applies everywhere I think - we had people here branded as racists/idiots/uneducated scum when they did not agree with the local and EU elite.

I keep reading people getting cheap UK stuff due to the GBP/EUR deal but I have yet to find these deals... how do you people pay? PayPal does not offer a great exchange rate, what do I miss? As for the matter at hand, I believe UK will have a little turbulence at first but they will fully recover , …

there is more to it in the Disney Sound Source speaker part as it is self-powered with a 9v battery: http://i.imgur.com/Tz8KDRh.jpg http://i.imgur.com/4l7y6gz.jpg I'd say your best bet is to use a multimeter to isolate the 5v wire and not use it at all. Then attach a passive speaker/headphones and …

Have a look at the jumper settings on the user manual: http://cdn.roland.com/assets/media/pdf/SCC-1_OM.pdf Setup the card at PORT=330 , IRQ=2 - the standard MPU-401 settings. Fire up DOOM or something, select "Sound Canvas" at port 330 and you should hear music. Under windows install the included …

Strange, once off-circuit you should be able to get accurate readings... maybe the tool you are using to measure is acting up? I could never get good capacitor measurements with my digital multimeter , every other function is OK but the capacitance function is a mystery to me. On the other hand one …

given that both the 24-voice SC-55 (SCC-1) and 28-voice SC-55mkII (SC-55ST) share the exact same default voice reserve settings Its the SCC-1 A (SC-55 MKII) so they both have 28 polyphony and the same voice reserve. The SCC-1A does not have 28-voice polyphony. I always thought it was a mk2-on-a- …

Regarding the battery question, yes it is possible to desolder the old one and put a socket in it's place. There is nothing special involved, just be careful to solder the socket with the correct polarity. The CR2450 battery in the unit is a 3v lithium one with 620mAh capacity - nothing special just …

Really? I had no idea 3dbench2 and doom would use LFB by default - I expected a fpr rise in these two tbh So basically this works in older games/programs ... or maybe newer ones like DN3D that you can select a non-VESA mode? I'll test this just for fun 😀

The SCC-1 utility works fine with other Roland MPUs and (at least) the Musiq Quest ones - so I believe it checks for more than an UART MPU401 port. But all is not lost, look here: https://www.vogons.org/viewtopic.php?p=319297#p319297 , there are some .bat files with all kinds of resets and further …

I see, yeah it does not really worth the effort to embed into the vga bios if it is so complicated. Tried the TSR today with my A55 and I can confirm that the Quake stripes on the right are gone, no matter what resolution one sets or how many times he cycles between various ones. I could not detect …
