Raspberry Pi Cluster Computer

It's not really possible to simply upgrade RAM or CPU. Both are one solid package soldered onto the board. Cluster computing also won't solve this - it simply does not work like you'd hope it would. ...

How to simulate the performance of a RPi in a VM?

QEMU is 50% slower than even the oldest Raspberry Pis from 2012. Suffice to say , if your code works fluently inside QEMU , it should perform better on a real Pi.

Thoughts on emulating a ROM chip with a Raspberry Pi?

If I had to do this, I would use a 100ns 62256 SRAM chip and added some dual-port logic made from six 74244/74245 chips to it. Then, I would use an additional µC, e.g. an ATtiny85 or such and clock ...
