What does sound like phonespeaker ? everything or just Adlib/OPL Emulation ? I should have phrased this better. Everything coming from the output has a very limited frequency range, audio, MIDI, and CD. I have not yet done a frequency analysis on the output but likely will do that at some point. As …

Cleaned up this nice Gateway P5-200 this past weekend. No problems except for on-board sound, quality is terrible, high noise floor and sounds like a telephone speaker. Any possible fixes or do I need to go sound card? Also can't disable on-board sound in BIOS either. IMG_2560.JPG IMG_2559.JPG …

I know this is an old topic, but does anyone here have Any detailed specs on the Marl board? I just picked up an old TriGem PC with this board, and can't find any information on it, beyond the chipset and processors supported. TriGem is long since defunct. Here are the specs: http://www.bcmcom.com/ …

Nothing special about the sound/video hardware, but I do like the ES1868 as a DOS soundcard. It was apparent the original used had user OS/2 as their primary OS. After working with it for a short time, I lament not using it more at the time it was released. Filename IMG_2028s.jpg File size 1.79 MiB …

This was an unusual system to obtain. What appeared to be a IBM-AT in a tower enclosure turned out to be a heavily upgraded Socket 7 system. System was used in an auto restoration shop. Once cleaned up it now seems to work fine. Will use the tower enclosure with a genuine AT system. PCChips M525/ESS …

Sure yeah I need to get back to doing some videos so maybe I'll do a video on restoring this one (Or one just like it since I've got a stack of PB machines). But yeah the riser cards should be swappable as long as it's the same height. If you do a full restore of this system, it would be a nice …

This is Roland EASE sequencing software designed primarily for use with the Roland MT-32. https://i.imgur.com/aqje1Pb.jpg As expected for 1987, it would require Roland MPU-IPC or similar. Running this software properly on DOSBox required much more effort, and a tutorial will be posted soon for those …

Yes, I'd like to. At first the HDD would not work so I checked voltage on 12V rail and read about ~10V. Then I tried to make adjustment and knob snapped off quite easily: I just need to find suitable replacement and check caps I suppose.

So the two patchwires modification is needed for the 5200 specifically in this case? Sorry I misunderstood, I thought the T3200SX would have a different pinout but apparently it has the standard 26-pin layout. Would the modification you mentioned also work for me on the T3200SX? Yes, I double- …
