Not sure I follow; the SC-88 has an MT-32 emulation mode no? Is it bad or does it just not work with games at all? Or is it just absent in the VSC? Some titles, like IJFA, use the default instrument set. Others upload custom instruments via SYSEX messages. A MT32 mapping can work for the first type …

You'll have to identify the old caps, ESR appears to be about 100 mOhms at 100 khz for the Samwha caps which is pretty middling. It might be enough for this application.

ESR is given as dissipation factor in that datasheet. https://www.illinoiscapacitor.com/pdf/Papers/ … _factor_ESR.pdf Unfortunately, they don't specify the valid tan delta frequency range, but hopefully you'll be pretty close to a comparable ESR if you calculate for 100 khz.

How do I find out ESR rating for both the ones that are currently on the motherboard and the replacement capacitors I am about to buy? Basically I am asking how do I actually choose the replacement capacitors. Identify the capacitors (manufacturer, series, voltage, case size). Find the datasheet …

alright, good one then. So far I thought all with SB under the DOS ended when all moved to PCI, also those SB PCI cards which emulate SB16, their MIDI port does not work. However it is really complicated, becouse there are no detailed information about the cards. Which of them in the list really …

Don't stray too far from the ESR rating unless you know that part of the circuit isn't used for feedback.

Well, here's the inside of the dead PSU and other than it being dirty, I don't see anything really that awful other than a slightly bulging capacitor. Probably shouldn't try using it again, though. I know after it popped there was a burning smell coming directly from the PSU. Also, the computer was …

For software that uses the MPU-401 interface to output MIDI, the CT2230 will require an external module or device (such as a PC with a software synth) for MIDI sound. As for their strengths and weaknesses, here's a few. The CT2230 and AWE64 both support 16 bit / 44.1 khz playback (most useful for …

I do not want to be a party killer, but none of the core libraries of Bass are open source. They are free to use (to a certain extent), but not open source.

Exactly,OPL3 is different compared to MIDI. However, MIDI also has two paths on these cards: In Windows, these cards have drivers that provide GM/XG synthesis (similar to external Yamaha modules) as well as MIDI output via the game port for other external modules. In DOS, you must use the MIDI …

Ah, those sneaky Roland engineers. So it's a third type of breakout box along with the original and MCB. dosgamer, Soundscape fakes some aspects of intelligent mode, but it's by no means a full and complete implementation.

Looks like an 80286 class machine, 3.5" FDD, 5.25" FDD (the HDD is underneath the FDD in case you're wondering), things like that. Also, check the CMOS battery for any leakage and replace the battery with a new one (some of them came with either 3.6V, 3V, or 6V). It also sounds like it came with …
