I think that is a
lament we all might have, but we have to also remember 
that 30 years ago, just
the hardware to play with this stuff was priced 
at 5000% of what it is today
even after adjustment for inflation.

 

 Interesting that you should say this because I was thinking the same thing. At that time I was still in school then in a new job. 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.

So we might have drooled over the
possibility if it existed, but no one 
here could have afforded the price of the
admission. Sad, but truthfull.

Having been on this list since it was on
Princeton.edu, I am amazed at 
the number of "newer" names who have come here in
the last decade, 
learned well, and are now busy building nearly all the the
wishlists 
we've all had since Hector was a puppy.

In fact, with all the new
talent, I would not be surprised to see someone 
build the coco 4 by taking this
6 chip circuit, laying out a new gime 
that will fit in one of the bigger
cpld's, giving us a full 24 bit 
memory range, while still maintaining the 8k
block size, so that all of 
our considerable Nitros9 software can continue to be
used. That would 
give us access to 16 megabytes of memory.

Imagine an minted
session using 15 megabytes of memory, simply by using 
the same techniques of
memory management that myram (mram in the repo) 
uses to setup a 1.7 megabyte
ramdisk on my 2 meg machine.  I think it's 
a doable project.
