mgcaret 8cb2f1b418 Bug fixes and improvements. 
Move ext 5.25 boot snippet to load at $800 since we expect that to be trashed by boot sector anyway.
Replace beq/bra combination with bne.
Fix flashing 'R' to actually be flashing 'R' instead of random memory contents.

mgcaret c4b1070329 Simplify bootable ramdisk detection. Jump to AppleSoft if no boot device. 
I discovered that there are more than one ProDOS boot block in the wild, so I
simplified the check for recoverable RAM disk to check card for $01 and then
anything besides $00 and $FF since most uninitialized RAM tends to have one of
those two values.  This is slightly more rigid than the boot code checks for.
I added a jump to AppleSoft if no bootable device is found.  I changed the
message a little bit, too.
I also added notes about the feasibility of using the RamFactor firmware.
