Update on 101 and too long

[Mike Dillon]

 Hi Bruce,

	I just got my dissesmbler, for 68XX code up and running, this
 past week and dissassembled a couple of PROMs (Not 747). If someone
 could use it let me know, I got the original code off the web somewhere
 and just fixed up some of the sections to allow it to read Mot "S" record
 files. Whoever wants a copy would need a C compiler. (I guess I could
 pass out a compiled ver. but I don't have the time to support and there 
 is no doc. on it) I am not sure what you are looking for on a O2 emulater
 I thought this would be pretty simple high Z source beteen 1-2 Volts ??
 (Am I missing something)
