"Sold as seen". Wish me luck, I'm hoping it's just "Can't test it because there are no Windows drivers" which obviously doesn't matter to me. SD20.jpg I'm obviously aware that this is probably Roland's worst sound module, but it was stupid cheap and I've kind of got a thing going for optical …

Remember that old radio I was building a Pi based internet radio in? Spent the last few nights working on the software: https://github.com/mo-g/thewireless It now compiles and runs on ARM64, can play internet radio streams and has a (janky, I was lazy) web API to control it with - which means almost …

Bigger headache is the missing power adapter. It needs 28V/205W, and has some funky connector, so that's going to cost. Original PSUs are insanely priced, so those are not an option. Are you on team "preserve originality at all costs", or team "preserve functionality over originality"? Because from …

optical.jpg These arrived today. I need a working sound card with S/PDIF input before I can work on the MT-D47, but at least when I have one, I can! I got a few spares. They were cheap as a bundle, and I haven't often seen short, well made TOSLINK cables. If I ever end up with some ADAT gear …

MU2000 from Japan. I can't find a voltage transformer for the 100V so I'm just gonna buy another 12V 2A psu. Honestly a better bet anyway even if the OG PSU was universal. A brand new PSU will be smaller, lighter, quieter, more energy efficient and less likely to blow up on you. Same reason I …

I'm just coming out recovering from an awful virus I picked up as well. Convulsions and muscle spasms are the worst to have :( Fortunately it wasn't something resistant and the cure was the fizzy aspirin+C every 6 hours. Normal aspirin didn't work at all, nor anything else managed to bring me down …

CM5 comes in Sparc, Asus, Banana and Raspberry flavors so maybe you want to be a little clearer. Sorry, I thought that was implied by the context of "25W, VideoCore, can handle every workload". To be more clear, I mean the probably-upcoming Raspberry. Not fitting in a standard ATX mount was my …

I think we started thinking about cable management when we needed to move well over 100W of heat and airflow management became important. This coincided with the window era. Once again demonstrating why my lust for an ATX compliant CM5 is so rational. Only 25 watts but can handle every workload I …

Good luck for sure on all counts. I do have a SC-D70 that I'm unlikely to use again, one of the switching ones, and I can send it to you, if yours is dead. That's really, really sweet of you - but I wouldn't be able to accept a $300AU gift from someone even IF I thought it was fair for you to "make …

Rehoused the Socket 370 build into a new chassis. Always preferred the desktop aesthetic to a tower but it's all subjective of course. I've always preferred the desktop aesthetic (especially since I'm tall - saves on monitor stands), but the simple truth is that with LCD monitors, they're just …

Edit: Or, how about writing of a minimal OS that acts as bootloader for DOS on UEFI PCs? Maybe a modified version of Minix 1.x/2.x can be used? Which installs a TSR version of a BIOS-UEFI translator, then loads DOS? Because, back in the day Minix could be loaded from a DOS system/from an image file …

Ok, RE: Manual - yes, my paper manual is a Japanese "100V Only" manual, like the sticker on the bottom. The PSU is definitely a switched mode unit. FET + baby transformer.

Ouch, I hope you get that working again soon, hopefully it's just the AC>DC section that's got a problem. I really don't get why these sound modules need to run off of AC, it's probably a sound quality thing but imo it's just unnecessary complexity. I was wondering about the edit to the your …

IMHO, it's very meaningful and helpful information for whoever is going to attempt fixing it, i.e. that there is very strong possibility the input voltage has nothing to do with the failure. That's really not the case. He'll have a set of new fuses and a correct input voltage. If it blows again …
