LuckyTech was an subsidiary of SoYo if I'm not mistaken.
They weren't though. Soyo's parent company was Soyo Group Inc, while Luckytech's company was Shining Yuan Enterprises (SYE).
A lot of SYE's mobos were sold under the Sector brand, as well as some under the Polaris brand, though not all of them as Polaris usually alternated - some of their boards are SYE/Luckytech rebrands, some are FordLian/Redfox rebrands, with some going deeper (as some of Redfox' mobos were subsequently rebranded Acorp mobos).
I also have the P5MVP3, a really neat and small MVP3 mobo (SYE was famous for making compact mobos), all recapped and running a K6-2+ 550 w/ a V3 3000 (though I might swap the V3 soon, I reckon a socket 370 might benefit from it over a K6-2) and ~256MB of RAM or so.
A few changes have been made since the photo in my first post about it was taken:
- a few of the caps (mainly the critical stuff but I'm trying to source some more caps and do the whole board) were changed to 1000uF 6.3v OST RLX off a useless MSI PM9M-V board, originals being some awfully dry Canicon 1500uF 6.3v caps.
- changed the BIOS chip as it was pretty rotten it seems - original chip was a AMD AM29F002BT, new one is a EoN EN29F002NT
- added a golden DIN5 socket, along with a new fuse, lifted from a long dead Biostar 8500TVX
- replaced the awfully bent PS/2 mouse header with a yellow one I made from a Raspberry Pi Pico kit I had
- dropped in a Celeron 533 for the time being, until I can either find the BIOS for P6VBX7A (which uses 693A and has Coppermine P3 support) or a 693A/596/W977 AT mobo BIOS and drop in a P3 850 or a 1GHz (since the mobo does look up to it, and 693A is simply a 693 w/ 133 support.)
There was also an Octek 430HX (or VX, not sure which) mobo alongside this one... unfortunately that one was in such a dire shape that it was pretty much impossible to repair.
EDIT: My bad, it wasn't an Octek it seems. PCPartner MB500N was actually the one that was there besides the P6VBX7. Trust me though, that one was a total loss.
