Regrettably, Most of my CoCo's have been in storage since my move summer
'04. So I've done little with them.
The J & R Banker requires a change in the boot sector of the OS-9 Level
One disk. The program is in RS-Basic, so someone with a understanding
of what's where on the OS-9 disk should be able to figure out what is
changed to accommodate the increased RAM.
In Summary, the J & R Banker operates in 64k for OS-9 Level One, with
the availability of a RAM-Disk, and I expect it will do the same for
NITROS9 L1 for CoCo 1 machines. The lack of CoCo 3 specific hardware
will limit its use of the 9309 optimized code as used in the CoCo 3.
