z80 running a unix like os

After seeing this it makes me wonder if the propeller 1 or 2 would be a better choice.

See ZiCog and RamBlade links in my signature. Z80 + CPM

www.fuzix.org has downloadable images e.g. for the z80pack emulator.

Considering that you have to have plenty of RAM and yet you are still crippled, what would you use it for?
Yes, the Propeller is a good choice for a microcontroller, and so is the P2. But how does a crippled UNIX make it better or useful?

I run a shell and a compiler and realtime system in Tachyon on the P1 in 32k RAM now. I can ifconfig, I can ls or cat files etc. But the important thing is that it is useful and efficient so I can do some real work with it.

There is a couple of ways to go:

1) Use a Z80 emulator on the Prop, ZiCogs or qz80. Run FUZIX on the emulation. This is going to be horrible slow. It will require using external RAM making it even slower. No fun at all.

2) Build a Propeller native version of FUZIX. With the large size of the Prop's 32 bit instructions compared to the 8 bitters you won't fit anything in HUB. External RAM will be required. That will be horrible slow. No fun at all.

3) Wait for the P2 and build a P2 native version of FUZIX. Now you have 512K of RAM to play in so it should fit nicely.

We don't have a Propeller 2 yet so that is no fun at all.

If yoy want to play around with a unix-like OS. On the prop1, look no furyher then Dave Hein's
