After an underwhelming responce to my last plea for help on my
problem with Toyshop I have done some testing of my own and
would appreciate any corrective comments.

It seems that the reason Toyshop won't work on my computer
(II+ Grappler+ NEC 8023A-N) despite the fact that it is supposed
to be supported by the Toyshop is due to Grappler+ pecularities.
In particular it is impossible (through BASIC at least and possibly
through machine language) to send a particular code to the printer.
The following is a list of things that need to be done get the
Grappler to output grephics.

	allow CHR$(7) to be passed (GRAPPLER intercepts this)
	set line length to 0 (Else APPLE will issue carrage return
		every 80 characters or so)
LOOK-->	change cntl-I to something else ( this is the good one
		since GRAPPLER uses cntl-I as its flag for
		messages this character is not sent to the printer
		cntl-I cntl-I does not send one, the most you
		can do is to select another character to be
		intercepted.
		
This cntl-I problem supports the fact that a different thing
happened almost everytime I ran the program.  This is due to the
character being sent for graphics after the cntl-I character
configured the grappler in a different way.

This is my guess after trying a program in BASIC any thoughts are
welcome.
