That's fantastic! Btw, do you know if that Videx board is what the Korean Apple ][+ clones used to make it do upper/lowercase? The Korean clones had that before Apple IIe came out.
Lower case could be done with a proper keyboard. The II used a 7-bit parallel ASCII keyboard and IIRC the II+ could use it. The Videx keyboard thingie would be overkill.
