My assumption is, that the LDA address access is too late at the end of
the instruction cycle, and the CPU already started the next instruction
cycle internally. HALT will be acknowledged only during the instruction
cycle following the LDA.
It would be interesting to measure, when the LDA pulls

for setting one of the keyboard types using the KB ident lines.

what is the host environment? Linux? or something else?
You have to set up some hoste networking, sometimes involving some
