Yeah but ridiculous pricing and you need 8 identical SIMMs to fill one bank.
Seems to be SIS5513 chipset.

Wow. God bless SiS and their weird niche products 😜

Wow its been a Long time since I last seen one of those. Can only imagine just how slow it must be 😮

A Socket7 board that can take 30pin SIMMs that's just silly 🤣

Not really slower than plugging 70 ns PS/2 FPM.
But it is much cheaper since you can use your old SIMMs.

I like that it has PS/2 support, and includes the backplate. Nice touch.

I did once have a S7 that took both. Forgot the chipset though, but it was one that could use a C6x86MX.

I like the layout of the board. And it has separated ISA and PCI slots. But I would have preferred the estate used for the 30-pin simm banks be used for other purposes on a S7 board - for e.g. an additional PCI slot (if possible) and increase the on-board cache chips perhaps.

And of course, it is expensive. Disproportionately expensive.

Is that S7 board, or S5? Take a closer look at the socket form and non-PB cache!

The R526 series from M-Tech are Socket 7 boards supporting up to Pentium 166Mhz.

Maybe it's Socket 5, though my understanding was that Socket 5 only went up to P133. Was split rail voltage a requirement for socket 7? I don't believe it was, because socket 7 existed before MMX chips came out. I believe socket 7 boards simply provide more current to the CPU. Strangely enough, this board claims support for a 5/3.3V split rail CPU. I wonder if it's merely a typo, since no such CPU exists. Socket 7 split rail was *normally* 2.x/3.3v.

It appears that this board has support for either pipeline burst cache or traditional async chips, probably so you could migrate them from your 486 motherboard. I guess it was a pretty good idea, but if this board was anything like my M-tech "Mustang" M534F (SIS 5571), it must have been a real pile of dog shit.

This board really just appears to be for 486 upgraders really. Nobody else would buy them.

It would be a sales push shop upgrade vs a new computer with more sales margin I'd say due to more labor involved rather than lower slapstick parts margins for whole low cost systems.

But seriously - I had a socket 5 P75 machine that would run circles around this thing with proper cache and better graphics.
