Power
https://rc2014.co.uk/backplanes/backplane-pro/
Powered from a USB adapter via the barrel jack, in which case a jumper will need to be fitted across the ‘5v power’ link.
On the board for a 7805 regulator (or more efficient 7805 compatible switch mode regulator) and capacitors if you wish to run from a higher voltage and convert to 5v locally.

25~100us pulse to the CE input
The MX26C512A is erased by EPROM programmer or
in-system. The device is set up in erase mode when
A9 =OE/VPP = 12.75V are applied, with VCC = 5V.
(Algorithm is shown in Figure 3). The erase time is around
1sec. If the erase is not verified, an additional erase
processes will be repeated for a maximum of 200 times.
