I missed that.  I might try it to confirm it.  But I believe it.

I tried this, and the system did not boot.  Looking at 030.000, I only read
0's.  With or without the extended configuration card, it came back 0's.  It
might be that there is something not right with my H-17, I don't know.  I
would have expected the modifications made to the H-17 when the XCON card
was installed were to make it respond to the ROM disable line on the bus,
not totally disable it.  I'm not seeing that.

Anybody want to power up a system with XCON, without RAM at 000.000 and tell
me if they still have their H-17 controller ROM visible?
