Blown away!

This is an amazingly versatile SBC with pageable ram!!! I was not expecting the module to allow me to page in RAM via the standard port $38, but it does! This makes sense as it is needed to support CP/M on these devices, but I was thrilled to see it.

As an SBC, this is a surprisingly capable little device, but I bought it to save space on my main dev computer. Pairing it with the SIO/CTC module (SC725) allows me to save two full slots on a backplane.

At this point, I would only recommend the standalone modules for each if you, specifically, want overclocking.... which you should, so buy them as well!
