A ``good'' 486 PCI motherboard is the ASUS PCI/I-486SP3G, it has a built in NCR810 controller. Uses bank interleaved memory (you must install 72 pin simms in pairs just like a Pentium :-)) to get decent memory speeds. And in general it just works. It has 1 annoying bug that has been found, and that is you must run the external cache in write through mode. I have not run the multi master PCI test on this board, so it may infact have problems with more than 2 SCSI controllers (this is a known problem with the Neptune chip set, but this board uses the Saturn II chip set). You only have 3 PCI slots on this board, so you could have a total of 4 NCR810's including the on board one. If your serious about this (and it looks as if you are) get back to me in private email, I'll be glad to bring another one in and load it with 3 NCR810 cards and hang disks on it and see if it lives. The other choices on boards here is the PCI/I-486AP4, I have seen reports of people using it but have no first hand experience with it :-(. It does not have the NCR built in, or the ATIO, but it does have built in PCI IDE, and 4 PCI slots. This board with a NCR810 would run about the same price as the PCI/I/-486SP3G. Note that some of the ASUS boards do not support the AMD DX2/80 chip (ie, they only have 25Mhz and 33Mhz clocks, you can run the chip, but at 66Mhz :-(). > Any suggestions/advice appreciated. :-) > > Thanks, > > ...
