 Have you asked Zilog ?
 I think this qustion was some legacy-maintenance project,
( hence the OTP Z8 and not FLASH eZ8 ) but the two are very similar.

 The new eZ8 tools are likely to be able to also generate code for the Z8,
(since that is where they came from ) and there are certainly examples on
Zilog's web covering the eZ8, such as this i2c
one :

http://www.zilog.com/docs/z8encore/appnotes/an0126-sc01.zip

 If you want a cheap debugger, then in the best tradition of 'making use of
what's available', why not get an eZ8 development kit, and use that
as a development vehicle for the older legacy device ?
 Some conditional compile may be needed, but you also get the ability
to launch new designs using the eZ8, plus good training in the
'Z8 gene pool mindset'.

 To be even looking at the OTP Z8, you must have some serious legacy
momentum,
in the form of existing products - which also implies existing code ?.

 Zilog do not show 'Migrating Z8 to eZ8' style whitepaper, but you could ask
them,
or someone here may know just what is the same/different at the lowest
binary and tools levels.
