Meh. The 8085 was a fairly crummy CPU that 'missed the boat', and Intel's SDK-85 / MCS-85 board was a very much under-powered trainer for it. Its niche was CP/M systems and the Z80 wiped it out in the marketplace. Also, who wants to have to mess around with its multiplexed address/data bus?
As there are people willing to pay silly money for the kit in unbuilt condition, unless Dave's got a project in mind for it that he'll get several videos out of + a lasting interest in the 8085, its better left in its box, rather than halving its value or worse by assembling it.
Personally I'd far rather see Dave's take on the design and build of an 8051, 6502, Z80, or 68000 based development system, (all processors that have left a lasting legacy in the embedded systems market) and followup on setting up the required legacy toolchain, debugging options and hands-on interfacing.
