[urq] urg computer question

[Buchholz, Steven]

... is this option truly practical?  At what level would you do the
redesign?  It would be difficult to implement a processor that executed
the same binary code as the MAC-02.  The schematic only gives so much
... there is that proprietary Hitachi chip in there too ... do we have
an user's guide for that device?  Since this is Steve E talking there
must be some reasonable chance this would be doable ... but it seems
somewhat time consuming ... wouldn't there be more upside in working on
something that would allow a switch to EFI?  

I was also intrigued to read Tony's note about Doc Keene's car ... he
actually managed to convince a smog tester that his car was correct? ...
or did he get it approved by a referee?  If there was some chance that
this is a possibility, one which would not raise the worry of finding a
smog shop to do the inspections every other year ... I've got to say
that is the way I'd really want to go for myself ...
