About the MZ80MROM PCB

MZ80MROM is an open source PCB design by Board-Folk, published on GitHub. It is a 2-layer board measuring 57.6 × 38.5 mm, with 7 components from 4 distinct parts.

Other key parts include the 27C512. By type, the board carries 4 resistors, 1 IC, 1 connector and 1 switch.

From the project

Sharp MZ-80K Replica Public

A multi-image ROM adapter to allow the use of a 28 pin EPROM at the M-ROM monitor position with switches to select the bank.

This will allow the use of up to a 27C512 EEPROM for up to 16 selectable banks, which is probably overkill. It's also useful just as an adapter to 28 pins.

Mounting holes were added to allow the attachment of nylon standoffs to provide stabalisation. There are no corresponding holes on the main board to screw into for these.
