Re: [N8VEM: 17403] Vintage + modern = fun



Sergey,

Yep, that's entirely true. There are definitely advantages of using emulators, but one can miss the experience with real hardware, which can be connected real actual peripheral devices. I can share that I was incredibly proud when prototyped the PPIDE "flying-wires-style" and it worked with real IDE disk. I wouldn't be so satisfied if it "just works" inside emulated environment.

Then there's the issue that the cycle-accurate execution of complex system (especially one that contains lots of async circuits) is quite heavy burden, and I personally doubt that RPi can handle it.

Well... one can install a software emulator of almost anything vintage (all the way through 80's, and possibly early 90's) on a Raspberry Pi... Much simpler and cheaper than using an FPGA, and all hardware problems suddenly become software problems.

But I guess some common interests of the people on this group are:
- Build something with your own hands. (Addicted to the smell of the rosin flux?!). It just turns out that old school DIP ICs and other through hole components are easier to work with than modern SMD parts. (But some SMD parts are actually pretty easy to work with too, so definitely suggest trying some small SMD projects as well) - Learn how hardware works, design something yourself. Again older components are more easy to understand than modern SoCs. - See some piece old technology in action (be that Z80 CPU, or floppy drives). It could be just the old software as well (but if it just that - use emulator).
