identifying terminal by escape codes?

I am trying to disassemble some ROM dumps from the SacState 8008
machine (per http://www.classiccmp.org/pipermail/cctalk/2010-September/291012.html
)

I can see a lot of escape codes being sent, but they don't make sense
(to me at least) as Tektronix 4023 escape codes, which is the terminal
type reported as being used with that machine.

For example, the first thing output after a restart is:
HEX		ASCII
1F		Unit Separator
0D		CR
0A		LF
3F		?

pressing the keys "!\h" would generate this sequence:

1D		  Group Separator
37		  7
7F		  DEL
20		  SPACE
40		  @
1F		  Unit Separator
12		  DC2
1D		  Group Separator
37		  7
7F		  DEL
20		  SPACE
40		  @
1F		  Unit Separator
14		  DC4

Does anything there look familiar to anyone at all? this would be some
kind of terminal from early to mid 70s.

Cheers

Jonno
