...still searching for a PC-Card for my macintosh that has LPT/COM Output via cables to hook up different pc-things.
my OrangePC620 does not work properly...always gives my K6-256 beside jumpred to K6/400 and does not offer cd-rom acess (...not ready) regardless IDE or SCSI CD-Drives.

I have a patched BIOS that will make it properly recognize your CPU. It's just a mapping problem in the BIOS that causes that mislabeled speed.

That would be interesting, but before that I have to fix what I found under the CPU.
Does not look that this should be like this...

Yikes!

Yeah it's a weird way to orientate the caps, but doesn't look like they would fit otherwise. Looks like you'd have to carefully heat and push the one side back and just reflow the broken joint.

Long as it's not lifted the pad, it should be okay

Oh and now I see C39 is displaced as well. Good luck with the repair.

I pulled mine out to compare. The cap is in a precarious position due to the sliding lock on the socket, so it needs to be tilted inward to avoid being broken off when the CPU is released. Maybe that was the cause?

Good grief, that's quite the construction...
Orange Micro had some odd execution choices on earlier cards too. The ISA stabilizer bracket on the 386 card is a few milimeters short, so tightening the screws all the way will bend the board significantly (and the metal cuts are sharp enough scrape through the board's solder mask.)

I also took some better quality photos of these Orange386 and OrangePC 290 cards.

To add to these earlier photos, a few more cards in better quality: OrangePCs 620, 340, and the LC630 version of the Houdini II board.

Coming into this thread a little late (and having not read all of it - so apologies if this is answered somewhere within the thread)

Dose anyone know what changes Orange Micro actually made to the the second revision Mac286 card to make memory upgrades work / work better? I'm currently working on a clone of the Mac286 and it would be nice to be able to incorporate this into the clone (the board I am cloning from is the bog standard AST version)
