> what about EBTR1 EBTR0 ?

  CONFIG  EBTR0 =3D OFF
  CONFIG  EBTR1 =3D OFF

Swing an' a miss

Sorry

I've also tried LVP =3D ON, and adding another erase/write routine
with all 0000 before trying to write the actual data

Meant to mention that the mV activity on /mclr and Vcc during the
self-write does seem to imply that extra current is being drawn. Don't
know if that's during the attempted erase or attempted write

The project started with just a 16F88, then I thought it would be
nice to add a display and storage, hence two chips

A couple of sighs away from porting the whole lot to a 2520 or
43K20
