I use an Altera Cyclone II with 4500 logic elements. You can get assembled boards on Ebay for about $20US. Altera's software is free, and very high quality. I didn't use a CPU because all operations must be serialized or time-sliced. With an FPGA, it's digital gates so things can be done concurrently if you wish. Also, I do a lot of chip design work for my day job, so I live, eat, sleep, stink, think, and drink Verilog. I have considered putting a Z80 CPU on the FPGA and using software, but I can easily do it in hardware. Also, verilog is usable for both design and simulation, so it reduces the number of tools I have to use. The verilog source code wont be of any use without the schematics and other documentation. I can provide a pdf copy of the design report on request, but I dont have time to provide any support. One PCB has been in operation over 2 years now, and I'm building a second one with green neon bulbs and a magic-eye tube in the center, but no surrounding digits. Now, if someone has some spare NIMO tubes I'd be happy to provide you a assembled & working board in exchange for 20 NIMO tubes (yeah I'm dreaming....) -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
