I will take a peek but it really sounds well removed from what I am after. The further removed from the straight up original 80086 instruction set and it's plain and unbridged ISA bus wire to wire true functionality. The more difficult it is to get software Witten durring that era executing properly …

Industrial systems I deal with are kind of picky. I need to find a few ...atleast motherboards.. the are genuinely fully IRQ/DMA ISA ..AT least compliant...I'd rather they just be "true blue" so to speak...I hate jumping thru hoops. Processor speed support...don't care..obviously x86. It been a …

Unless you are confident about de-soldering do that as a last resort. More bad than good can easily come of it. Especially with potentially damaged holes/pads/traces. Even if I planned on desoldering to investigate in such cases I find better results by fluxing and heavily re-soldering it first. …

I usually use zippo type lighter fluid to clean misc stuff off boards and contacts and then use alcohol(regular rubbing is fine) to finish cleaning. If its hard to remove alcohol alone doesn't usually do the trick. I used to repair xbox 360's and it works well on corrosion and even thermal paste but …

Thanks all. I'm pretty confident between what you provided and what I've dug up on what route to go. Feeling I'm not tied to a 486 or sub p133 as long as proper underclocking of bus and cpu it makes starting a lot easier. Aside from the standard single board computers I've found. I've also found …

If retro/vintage is explicitly felt by this group as "the real deal" date stamped from the given era vs identical hardware production far past general use..then i'm obviously out of place and I appologize. i'm merely trying to hammer out exact details of the vintage equipment tomale the best …

If Jorpho is right and I picked the wrong place I appologize. I just picked the forum I found with what seemed to be the most concise postings thus far on answering questions I had. Maybe I was over complicating things for myself. Maybe I confused architecture compatability between pentium and 486 …

Well the time is comming(ok its already arrived) where these 486 dos/win3.1 machines will need replacing hardware wise(not just the hard drives).I could use some assistance to make the absolute right choice. The computers in question are used for industrial control...but I know where to find the …
