Re: Expansion Bus Connector for MZ-700

Yes I use it for my PCB and it fits perfectly in the connector of Sharp MZ-700.
The 90 ° ebay connector works because I have it too.

Re: MZ Collection

Is the left electronic board of the first picture (the green PCB) the QD interface?
It looks like it has exactly the same components: LS00, LS02 and LS244.

Re: MZ Collection

Hi,

The electronic board is more like an 8-bit output data buffer (74LS244) associated with address decoding (74LS00 and 74LS02).
There is no EPROM so no software to work.
