Hi
I am looking for 80486 motherboard or laptop/notebook schematics preferably with OPTi chipset but *any* would be helpful.
Specifically the OPTi 82C465MVB or 82C495XLC chipsets would be ideal. After several days of looking I have yet to find even a single 80486 motherboard or laptop/notebook schematic. Even 80386 schematics are rare and I haven't seen any yet.
A total jackpot would be if someone has the following document which OPTi published on their BBS back around about 1994 or so. They refer to it in their 82C465MV datasheet (rev 2.0) but its not available on what's left of their website.
Any help greatly appreciated.
PS, these were fairly common 80486 chipsets back in the day. There were also some 80486 laptops built using OPTi chipsets such as the Zenith Z Star EX

OPTi 82C465MV+82C602 Demonstration Board Schematics. Printed version and OrCAD files both available; files also available on BBS (see Appendix A., Accessing the BBS)
Any help greatly appreciated.
