286 keyboard inductor gone bad
Posted on 2025-05-12, 00:34
I broke the inductor trying to fix the broken trace. Just looking for suggestions on what to replace it with. One thread suggests 1-4 uh. And by chance anyone ever seen this board I think it a zenith. It’s a 12 mhz and the sims let it max out at 16 mb. Filename IMG_0805.jpeg File size 1.77 MiB …

I do have a question if someone can help. If I want to use an mt-32 with the picogus, do I need to set it to MPU-401 mode? Is it possible for it to emulate the Gus while also using the midi out? Or is it just one or the other? the only difference you have to take into account is if you need …

For some reason UNISOUND is setting up my AWE64 with DMA1/HighDMA1 on the first try. Starting BLOOD results in a crash complaining about high DMA being incorrect. Running UNISOUND again after that sets up DMA1/HighDMA5 as expected from my BLASTER variable: BLASTER=A220 I5 D1 H5 P330 ...which is the …

Code suggests keyboard controller. I would check pins / traces from the at socket to the controller. Continuity test with a multimeter if you can. Is the keyboard controller socketed? If it is remove and deoxit/ isopropyl clean it.

I also decided to purchase a picoGUS. I have an Asus p2b mobo with an audigy PCI for win 98 and an ensoniq soundscape s2000 and sb16 ct2800 for DOS 6.22. I've removed the ct2800 in preparation. I'm wondering if they plan to eventually integrate mt-32 emulation for those who have the ROM files. That …
