I built one on prototype board..... images before the compact flash adaptor

The Z80 and SIO chips are circa 1979 but the 128K static ram (wasted really
seeing as only 64k is used due to the minimal address decoding), Atmel
29C010 Flash ROM (rather than EPROM) and compact flash card make it an
interesting old/new mix.
I am planning to use more of the flash ROM by allowing multiple ROM images
to be selectable. Might even go crazy and add a blinking lights panel.

Are there any modern ready-to-go SBCs capable of
running CP/M?
