Horse,
Didn't you see that bit in blue saying,
"Real email address required
Even if not publishing email, email required"
Using a "Handle" risks the wrath of the Moderators...

"If I have a program that starts at 0x0800, shouldn't I expect to have more than 2K of ROM?"

That is true - and it is completely deliberate!
Basically, it's to keep the free download for purely evaluation purposes - otherwise you'd be getting a complete free full-function development suite for any processor with <2K on-chip ROM!

This has been discussed here before - try a 'Search' for "Keil" and "Evaluation"
