Re: Unknown hardware for MZ 800

If you are uing the MZ800 FDC you dont need an expansin unit. Bur there was an expansionsunit to conect MZ700 FDC and other cards to the MZ800.

By my self, i have bulid an busadapter to conect the MZ700 FDC to the MZ800 ( you must remove the (ep)rom from the MZ700 card !! )

Re: MZ800 is not an euro MZ1500 !!!

I have written it on wikipedia, but after times it was erased :-(

Intressting, the MZ1200 ist an reduced hardware from the MZ80A, but compatible with the MZ80K :-)
