As you said we must see the inside. I have seen 2...

Re: MZ 700 - rear view

Sorry to raise you hopes it is a MZ700, the "Sharp MZ700/8000 - EXPODED-" by John Simpson has the rear image of the MZ700 on page 5 as a mirror image.
The MZ800 rear image on page 6 is correct with the system switches visible.
Your image after saving and previewing, I can not see the switches.

Re: MZ 700 - rear view

From the position of the reset button and the volume control on the righthand side of the connectors indicate you have a MZ800 not a MZ700.
The large connector with the system switches and the joystick i/o port.
The small connector is for printer output.

The SUC Sharp Users Club will be 40 years old in 2020. You can still join for 2019 and receive copies of vol 1 ...
