[Coco] Relocatable ROM monitor

[Dave Philipsen]

I got the monitor working on the CoCo.  It’s not relocatable and it relies on POLCAT and CHROUT right now: https://youtu.be/dcT5mnyPtCw

It’ll take me a little time to write a keyboard scan routine, character out routine, re-format for 32 columns, and re-write a few sections for re-locatable code.  It allows you to view/edit memory locations, do a dump of memory from a specific address, and execute code at a specific address.  Is that kind of what you want?
