And DOS, NES, Amiga, Apple I, Apple II, Z80 ! I am new to FPGAs so it is a bit difficult to know what to expect from a given number of LUTs, but you can compare between models: the big version of ECP5 in ULX3S has 85k LUTs while the previous well open-source supported FPGA (iCE40) had only up to 7.7 k LUTs, so more than a 10x jump :)
