RE: HP-25 DIY with Z80
Very cool! I have a Z80@20Mhz "Zeta" single board computer I built several years. ago. It runs CP/M with dual 3.5" floppy drives, as well as an add-on terminal board that also emulates 8 8MB hard drives (the largest supported by CP/M!). http://www.malinov.com/Home/sergeys-projects/zeta-sbc

It would be cool to have it act as a calculator and drive an LED display.
