[Coco] ROM Development question

[Zippster]

It is absolutely amazing what we have available for developing stuff today compared
to back then.  The tools, and especially the information available on the internet.

For example, with part of my tax return, I just added a new 32” Benq design monitor and a 
new graphics card to my dev/cad machine.  At  3840 x 2160, 8.3 million pixels driven by dual NVIDIA GTX 760s.
This thing is going to be an incredible tool for board design.  Pure science fiction back then,
and incredibly expensive or unavailable just a few years ago.

It’s a great time to be a hobbyist involved in electronics.   :)

Not only broke in money. but also in time as my schedule was somewhat chaotic. fast forward 30 years and now I find myself in a world of Windows, 64 bit computing, Raspberry Pis, Arduinos, emulators and much more technology that allows me to get back to the roots of computing employing technology that was only dreamed about 30 years ago.
