Indeed. I remember pointing out to Dennis at the time that the uSRV3 boot
strap code for the 3B was larger than the V7 kernel.
That said as much as I miss the simplicity of v6 & v7 I would find It hard to
use in my daily life without some of the tools we have today. Ie how we told

The diode board was used for the boot strap before large rims were cheap. DEC
predates Intel (who got its big start with the invention of the EPROM - Only
after they micro processor did they get out the memory business which we are
only recently re-entering).
As for single stepping sure. The

explanation of programming that involved wire snips. It was interesting
and brought home to me the concept of memory pages and such. I thought I
would share the screen shot with y'all.
