[Coco] 512K AND Beyond??? How FAR Beyond???

[Stephen H. Fischer]

I have one of Tony's 2 Meg CoCo 3 memory upgrades.

I used it only from OS-9 but I have one CoCo3 DECB program that allowed 
Strings to be placed in the second bank and sorted. The subroutines could be 
used in other programs. Docks are in the DECB manual for the CoCo3. PM for 
source.
-----------------------------------
I did load all of the "C" compiler into memory, the source into a ram disk 
and with 2-3 windows on the same screen at the same time, It was a beautiful 
"C" software development system. My Colorful SLED ED6 editor could use 40x12 
size windows.

A eight (8) Meg upgrade was made, I think only 2-3 persons had it besides 
the developer. The docs are available, PM me if you are interested. I do not 
post links to a certain CoCo file location.

More than 2 megs you cannot use from DECB effectually the CPU is just too 
slow.

These days, if you are not stuck with using real hardware, the emulators are 
so much better. VCC I think does go to eight (8) megs.

1-2 meg upgrades would be very rarely used.
