Hi IanB! I haven't had my T5200 out of its case in months, for fear of it dying on me. I still need to install that rechargeable cmos battery. And I probably should recap it, but I need to get more experience soldering, first. And all of which got tossed into a cocked hat yesterday when the HD on my …

Better replace the power supply, it only supplies 300 mA, while the MT-32 needs a 650 mA power supply (shown on your second photo). Yup, that's why I haven't plugged it in yet. Plus, no point til I get some midi cables. I need to look up how to tell center-positive / center-negative on such power …

But if you already have some midi instruments and you are looking for adding something new to your setup - SC-50/55 sounds are good yet pretty 'generic' while MT-32 has very distinct 80s sounds (almost as good as Roland D-50)… Have you already played around with MUNT? If not - do it and decide for …

Okay, if I decided to forego the MT-32 / SC-55 route, and just get a vintage (small) keyboard from the 80s/90s for music composition under DOS, can anyone recommend midi keyboards I should look for? Use a DOS-based sequencer like Voyetra Sequencer Plus Gold, alongside a DOS-based MIDI interface to …

Hi I would like to create a topic about the old pc cases and we could use some "collective memory" to recognize the old pc cases. I mean if you remember - "I saw somewhere same/similar case from this year, with this configuration" - you can share this information with us. That helps to build more …

MT-32 is great and sounds way better than AWE32 with stock soundfonts, but keep in mind it's not General Midi compatible and it's a problem if you think about making midi music. Also it's pricey. So something like SoundCanvas SC-50 or SC-55 would be better IMO. Would an SC-55 sound the same, have …

I've been wanting to do more and more on DOS systems, and one of the things is music creation. The system I'll be using will most likely be a 486 DX2/66, and probably with a Soundblaster Awe32. Do I need/want an MT-32? I've seen several videos and reviews (LGR and 8-Bit Guy, for example) of the MT- …

It would be somewhat sacrilegious, but I can't help but see the T5200 as having a lot of potential as a 'sleeper'. Completely gut a dead one, and you could likely stick a modern mini-itx motherboard in there if not larger. Same with the screen. I've actually thought of that, and would love to do …
