AWE32 is priced at insane prices. Seriously, they're pricing them like Roland hardware. I bought four AWE32's on ebay last year for $60 shipped, with memory on them.

Oh, also, the "good power" line (yellow) shows 4.9v...so either both power supplies are ultra-low quality and have it tied into another 5v line, or the reading is well within specs. The power good line is not connected to another +5V line. Is held low by a voltage monitor circuit until supplies are …

User Feipoa also experienced the really warm RAM modules on his Abit FU340 386 motherboard. He was never able to determine the problem though (and he has the equipment to do so). I also have an Abit FU340, but my modules do not get hot. I'm really curious about what's causing it. -5.99 does seem a …

Tested the voltages. +5 was 4.92 +12 was 11.95 -12 was 11.96 -5 was....-5.99! <---could this be it? I also noticed the RAM modules were particularly warm! Thoughts?

I assume you have tested everything in your spare Mainboard. So it looks like your Mainboard is busted. So next step would be to hook up a logic analyzer... Did you measure the Resistance of 5V to GND and 12V to GND ? On the Mainboard ? Could be that some Capacitor failed. https://en.wikipedia.org/ …

I do have a post card (that exact one). Didn't show any error codes...LCD remains "- -| - -". It does show the reset works, as the LED's change when I hit the reset. No IC is running hot or very warm. =| (BTW, thanks for all the suggestions)

Well, since nothing is burning when power is applied to the motherboard, use the multimeter to verify each power pin is actually reaching the system. Measure voltages at the AT PSU connector on the bottom side or if you are brave enough just measure from ISA slot. Power supplies +5V and +12V should …

Don't let it consume you :) One day we will move onto brand new retro motherboards recreated with old stock chips or FPGA which will be much more flexible and satisfy wide masses. I guess even with hoarding its all about enjoying it while it lasts. Oh yes. My plan is to slowly sell of each system …

That is true, but sitting there doing nothing is almost the same. People like to do a lot of things but lack resources, maybe you could make somebody happy by donating a few. Donate to whom? The scrappers? Maybe my local kindergarten school will want one, because, ya'know, they know how to run DOS …

Do you even use 80% of them? I only have three that I use, and they aren't pictured (they're in my office hooked up). Better stored than goldscrappers. Did you take out the batteries if possible? Batteries taken out/removed from all of the motherboards. 2-3 packs of silica gel packs thrown in each …

Interesting. I'd love to see how this compares to the Roland SCD-15 (SCB-55) and NEC XR385 (Yamaha). Kudos! I have your original S1 Dreamblaster. Thanks for putting in the work for the community!

better question what company is still buying 486 class hardware new?

You can try system.ini.... [BOOT] language.dll=langeng.dll It might ask for disks. I can't remember if Windows 3.1 asked for language when running SETUP.EXE...you could try running that in the Windows directory too.
