Like I said, 32b I/O is unusual in this form factor. 486SLC (i.e. souped-up 386SX with internal cache) is about the best that's fairly commonly available and won't roast your small system. I see, thanks. What would be the smallest 386 or 486 with 32bit bus ? I used to have a 486 with VESA VLB for …

Are you trying to find a replacement/upgrade board for your really small case? Or a case for that board? Both. Although most of the boards I saw in that size are 386SX and I'd like either DX or 486. I'm looking for a small x86 (preferably like 386 or 486). I've seen SBCs but they seem quite …

I think it is approximately 6x8 inch or 20x15cm, what size format is that ?

I'm having similar issue here Help / Advice repairing battery leak on Compaq Armada 7710MT if somebody has clues, thank you!

By the way, would anybody have close up photos of the same region of a working motherboard ? That could help me see if some traces are totally gone

Actually, it turns out there was some leak damage, around the battery connector. I tried cleaning with isopropyl alcohol, but it still shows the problem. I tried checking the traces and many are good, I couldn't check them all because I'm not sure the isopropyl is cleaning all the rust and some pads …

Thanks for the detailed explanation. I will keep an eye on batteries on any laptop I get.

Hi, I found an old Compaq Armada 7710MT that does not work properly, so I'm looking for troubleshooting or other tips to restore it. When powered on, all three lights on the keyboard light up and sits there. Nothing on display. No beep either. Like in this video from somebody else: https://www. …

Quick question, how hard it is to solder these adapters ? Or do PCBWay or other are able to fully populate them on order ? It would be interesting to see a picture of both sides of the adapter, I did not find one.

Thank you all for your replies! I was also trying to find the schematics but I did not find anything for those models, any ideas ? Also, does anybody knows if the CPUs are socketed ?

Just in case anyone is interested: My "retirement" project: I am publishing some 40+ years worth of source code to "stuff I've written". This includes my DDS products, lots of "internal tools and utilities" and other misc. "stuff". Most of it is C (mainly for my own compiler - one of the items), …
