< As for the suggestion of using a DEC alpha to emulate a Z-80... I thoug < about it but, those darned Alphas are way too expensive for us hobbist Some of the early slow ones (under 200mhz) are in the used market for under a couple hundred. The other approches witll cost that much or more for superfast memory. < < Tell me more... what are Verilog, Xilinx or Altera? FPGA, Field programable gate arrays. The fast ones are down in the 2.5ns range per gate. < Anyone know if Zilog is going to beef up the Zx80 line???? The z380 series is that. There is already a z382. Allison
