Using an fpga is strange IMO when you can still just buy z80 chips. I made a pretty simple home brew computer in college this way.

- soegaard 6y agoYou need it for graphics (and the ulas).
- rleigh 6y agoFor the Z80 alone, this is true. But it also needs the Ferranti ULA which is no longer manufactured, and was kind of an early FPGA, or the Amstrad 40077 for the +2A/+3, which is an actual gate array. I can imagine to get output for current display devices, an FPGA makes perfect sense as a current replacement part for these obsolete and unattainable parts.
- tyingq 6y agoYou can do some interesting things, like a 100MHz+ Z80. Also, the fpga emulates not just the z80, but pio, sio, banked memory, CRTC or similar graphics with a modern vga output, etc.
