1. When it is put in to replace the DL11-W (which
would be much easier to
reconfigure later, what with its switches), it causes the machine to halt at
173524 on powerup (this also happened before I removed the two caps, so it's
not that).
The first thing I would check is that you've set the address and
interrupt vector jumpers correctly. IIRC one set is 'open for 1', the
other set is 'shorted for 1'. Make sure you've not got that wrong.
