@Giemme: Wow! someone is doing a Z80 emulation (a compatible super set of the 8080) whilst all the while I was working on my 8080 and we have never crossed paths here on the forum. I guess it's because I don't have a Hydra so almost never checked the Hydra forum.

I have to say I found it hard enough to get the 8080 logically accurate (What with the incomplete/inaccurate Intel documentation I have) never mind getting cycle accurate timing or even up to original 8080 speed. I really don't have the tenacity to tackle the Z80 which has a lot more instructions/registers/addressing modes etc.

One of my goals was to get the 8080 into one COG, which I have done, and surprisingly it's within a a few percent of the original 8080 speed, about 350 thousand instructions per second. I'm sure that to do a complete Z80 at Z80 speeds would require multiple COGS.

One annoying thing about the 8080/8085/Z80 family is the AUX carry flag (half carry) which has to be set correctly by all arithmetic, logical and inc/dec instructions. This takes a bunch of Prop instructions, consuming space and time, and yet is only actually used by the DAA instruction which 99% of software does not use! I'm considering having a version of the 8080 emulator that does not set AUX and implements DAA as a NOP. I'm sure most CP/M programs would still work.

Fortunately in the CP/M world very few programs actually rely on having a z80.

I don't know about the ZX81 (and similar) but do they really need ALL the Z80 ops to function ?

So yes I'd like to know how you are getting on with the Z80 as well. Very interested to see your approach.

This index is a great idea Cluso. It's also great to see all the other emulator activity going on in the Propeller world. Nice to know I'm not the only one trying to achieve the (almost)impossible and ultimately useless :)

BTW the PropAltair running full up 24K CP/M is here http://forums.parallax.com/showthread.php?p=711157 The link you have is for PropAltair configured to run BASIC. It's the same really but saves anyone having to wade through the code and figure out how to swap from BASIC to CP/M. Perhaps you could add that link also.

Is anyone interested in a plain 8080 CPU only emulator version with no BASIC or CP/M. Just include your 8085 code in a "file" statement and run?

What a great list. And now it should double in length with a dozen new machines from PullMoll and co. to add to it. Excellent.

Please could you add Zog to the list?

Some time ago there was a debate here about whether Zog was classed as virtual machine in the same way as a Java VM or as an emulator like, well, all the processor emulators on your list.

I was arguing for Zog as VM as there is no "real" ZPU to emulate but was out gunned by the majority who said Zog is an emulator.

So I bow to the majority and ask for Zog to be included on the list of emulators:)

The Propeller Javelin JVM should for sure be on the list as well.

@heater: Added. It does not matter whether it is an emulator or not. It should be listed here and I have done so. Thanks.

@Drac: Would you like to describe your pcbs here too.
@humanoido: Would you like to place a link and title for your languages thread (update·your previous post to avoid clutter)·and I will place it in the languages list.

I have updated the list with some extras. I know there are others. I was in a bit of a rush, but I thought I should add some of the languages specifically designed for the prop, but no links yet. I encourage those who have written the code to place a post here with a brief description and a link to your thread where further info can be obtained.

I will delete this post later to reduce the clutter.

Since it is so quiet lately in our foras I bump this thread for the nice list of emulators written.

PII is coming and then those emulators will FLY compared to the original Computer they emulate...

I am impressed with what has been done with Prop 1 ... what a wonderful chip this is.

Enjoy!
