IIRC, the 8751 is an EPROM (windowed package) version of the 8051 MCU. The
thing about the 8051 (and the 8052) is that it can also be used as a CPU -
add a 74LS573 (or 74LS373) latch and a bit of decoding and you can disable
the internal program memory and use external memory instead. I use
8051-derivatives a fair bit - Atmel's AT89S8252 is a particularly nice
chip - basically an 8052 with 8k of internal FLASH memory and an SPI
programming interface.
Later.
