I really like having usable, cycle-accurate reimplementations of classic hardware. Cycle-accurate software implementations are great (for example people have made drop-in "hardware" CPUs [1] which are actually implemented in software on a microcontroller) but FPGA-based implementations are interesting not only in that they create a usable version of the hardware, but because the HDL implementation shows how the logic design could be implemented.
And modern FPGAs have tons of gates, more than enough to implement an entire system from the 1980s.
Interesting. I used Apple II's in elementary school (early 1980's) and then some Macs but I had never even seen a Lisa in person until going to a computer museum about 5 years ago.
