It happens. Not often though.

I'm sure that the bulk erase specification is different. Also the programming
time may be different.

The definitive source is the programming specifications. Microchip has each
and every programming specification online. One of the great things about PICs.

Finally it's always a good idea to ground the LVP/RB3 pin when programming to
prevent a possible low voltage/high voltage glitch when programming.

You can still program it using the high voltage. It save the abovementioned
LVP pin.

Not exactly. The 871 can write its own program memory. So it's possible to load
a bootloader into it. However it's not built in.

prog84 will probably have problems with the bulk erase and the memory size.

If it's a Tait style parallel programmer than maybe David Tait's FPP or Nigel
Goodwin's winpicprg may be a better choice.
