8-bit acorn hardware • Re: 62256 as 16K SRAM

The sideways ROM sockets on a BBC B don't have pin 1 connected to anything.

If using SRAM, you can connect it to either 0V or +5V. I recommend +5V because that is easier (available from the nearby pin 28) and that is more compatible with EPROMs. No need for a resistor.
A bit less conventional, but I guess you could also connect it to pin 2 (A12), which is even closer?
