Plainly, they screwed up. What happened was that the RBF and SCF defs
were left off of the Development disk. It's somewhat murky yet as to
who dropped the ball (Tandy/Microware), but Microware has made good.
They have posted versions in their new Forum on Compuserve (GO MSC). I
will get copies of the SCF and RBFDEFS and post them here. I think
that they are still in the old (not *.a) format, but as you
discovered, that's no big deal.

There are a couple of new system state debuggers out. One is called
ERINA or SERINA. Believe that Jim Omura can expound on this product.
It will allow you to do exactly what you're trying to do.. view system
memory. The basic trick they use (I think) is to use a pseudo-device
driver that acts sort of like a full system ramdisk. This way, any
byte in the system can be read or written. Powerful, but dangerous.
