I was thinking that 386-33 board looked like a DTK that I had bought new at work about 1990 but it's missing the "step" in the board outline (top edge in photo) that you would normally see in a full-AT form factor.
But it does have an external cache so should be fast. The DIP switches must be for setting the start address for the optional proprietary external memory card that would have plugged into that end slot.
The DTK was the board I first tried Linux on, Slackware 1.x. I eventually used it for dial-in PPP access to the company network.
Lastly, the RTC chip looks similar to the SGS-Thomson M48T02 used in my Sun IPC. Apparently, the clock can be stopped to reduce battery drain, something I do before putting mine in storage. It's in a socket but will need the battery hack next time it fails as replacements are apparently no longer available.
