	The TC02 also supports a very nice little boot strap loader.  If
you pump the following into it, it'll skip the 1st record and the tape and
load the 2nd into memory start at 0.  It goes like this:

	0/0 <CR>	; set a reset into location 0
	0G		; execute a reset 
	000002		; echoed after 0G (reset)
	17772522/100001 <CR>
	17772522/100001 <CR>	; tape should advance - 1st block loaded
	$6/10000 <CR>		; Set stack pointer
	0G			; start boot.  Some O/S need CSR and unit
				; in R0 and R1.

	I'm sure you can do this with a VAX as there is nothing to PDP
about it.

	Let me know if you have any problems or questions.  Good luck!
