Need Assistance With EEC-Sucka

[ROBO5.8]

Lyndon,

Thanks for the reply.  I've also tried the EEC-IV on the bench with power
and there is no difference.  The EEC-Sucka only returns all "FF".  Seems to
me its not commanding the EEC-IV correctly or the ROM contents are not being
captured correctly.

Bottom line, is the info packet I took off the web a while ago accurate?
Has anyone built it from scratch and are they getting good data on an
EEC-IV.

Thanks ROBO
