I tried several games, including doom2 and tetris classic. Doom2 is especially nice to setup, allowing you to select the midi port address. The output from the sc-55 is connected to my external mixer. This mixer is connected my amplifier, but it also has a headphone output I was using for the test. …

Thanks @keropi, just ordered one. I'm still unsure this is the problem but it's worth a try, and anyway I wanted to have a spare cable 😀

I really doubt my cable contains any electronics beyond the pure copper wires. And yet, it works fine with the mt-32 which for me was ruling out it was a cable issue. I may try to get another to give this a go, any suggestions on where to pick it? Last time I ordered from aliexpress 🙁

Hi there, I am having the weirdest and most annoying issue while trying to make my SC-55 work in my old 486 DOS gaming machine. I am using an ES1868F audio card as the MPU-401 interface, at address 330h (also tried 300h). When connecting my MT-32 via a db-15 to midi cable music is produced without …

I took some time to find coolers in ebay that would clamp to the cpu (around 10€ shipped, including fan and heatsink). This thermal adhesive solution sounds great in theory but I have my doubts it will perform adequately in practice. What's been your expirience with them so far? Is there an easy way …

Based on what you say, I guess my dx2 is faulty probably bc it was operated without any heatsinks by its previous owner. Damn 🙁 I'm back to 33Mhz. I'll try the heatsink when it arrives as it's already on its way. Thanks!

I'm having problems with a dx2-66 having a quite unstable behavior without any heatsink or fan attached. My previous dx33 would work just fine without them. I just ordered one to try it out and see if it solves these issues or is just a faulty CPU.

Some more additional info: 1) the J23 conenctor (LogicLock socket) has a bunch of cables attached that are not connected on the other end. Could this be an issue? 2) the keyboard lights go on at the very moment I press the power button, and then switch off 3) The psu seems to be working (fans go on, …

Hi everyone, I got my hands into a good looking ibm ps/2 model 76i. Despite the good looks the machine seems to not be wanting to boot at all. I get no error codes on screen, no beeps come out of the speaker and really I'm a bit lost about what to do to diagnose the problem(s). Any ideas on how to …

Thank you all for your responses, despite the slightly offtopic question. My main use for the sc-55 will be for general midi games, although I may try mt-32 emulation from time to time. Guess I can postpone getting one of this cool hardmpu ISAs, but it's definitely in my buy list at some point.

I just bought a SC-55 from ebay, and was planning to use it from the game port of my current sound card. After reading a while, I'm not sure whether the problem with intelligent mode and game ports is only an issue with the MT-32 or I would also need to make use of a mpu-401 clone, such as hardmpu. …
