Picked up this Epson Equity III+ this past weekend. I'd been seeking one of these for a little while. Prior to finding this one I couldn't even find photos of this particular model from the Epson line.
It's a 286 system (12 MHz AMD processor) similar to the Epson Equity II+, albeit with some more interesting features. It has nine ISA slots (seven 16 bit and two 8 bit), a triple speed selector (6, 8 and 12 MHz), a front slide out motherboard (once the RAM/BIOS board is removed), and three front accessible 5 1/4 drive bays.
Interestingly that despite having an extra ISA slot, it's still a couple inches narrower than an IBM 5170 (or typical clone).
I've got a few ideas for outfitting this system. I'd like to try to get at least 3 or 4 sound cards in it, as well as a CD-ROM. I also found another seller selling surplus internals from another Equity III+ system. So I ordered that extra motherboard and will likely use that for overclocking experimentation. I'd like to try to boost this up to at least 16 MHz.
Ultimate goal will be turning this into a 286 multimedia machine. Who needs a 486 for that anyway? 😁
