[Coco] 256K J&R Banker and OS-9

[Bruce W. Calkins]

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.

Do you need the documentation and/or the software that goes with the 
hardware?
