I have a 386SX that has a single 72-pin SIMM socket. It xseems to be a 1991 design by the stickers on components.
Even more weirdly, the machine could be equipped with a 286 daughterboard instead of the 386SX. I wonder if it just discarded half of each memory access to fill the 16-bit bus.

- hakfoo 4y agoMagnavox Headstart/SX. Here's the mainboard diagram http://www.uncreativelabs.de/th99/m/P-R/34385.htm http://www.uncreativelabs.de/th99/m/P-R/34385.htm (although they claim it's 20MHz, the one I have is 16) It's strangely overbuilt-- very feature rich BIOS, almost tool-less chassis, 72 pin memory socket, lots of surface mount parts, but paired with the slowest 386 on the market and a hard disc that was probably about 3 years out of date (Seagate ST351A/X-- capable of running in that weird 8-bit IDE mode) I have to figure it was Philips flexing their last few years of being a premium electronics manufacturer-- they can make a nice PCB and chassis but still have to buy the computery stuff from elsewhere.
- rasz 4y agoIndeed appears to be middle of 1991 design. Nice!
