Sounds good @Cluso99 . Any idea how much faster your emulated Z80 goes on the P2 at some given clock rates vs a real Z80?
I have a dual P1 system used in a 3.375MHz Z80 Microbee acting as its video/SD card filesystem controller, but maybe I can run the entire thing now on a single P2 instead of on my original HW.
@msrobots,
CPM is not running yet. I just get up to the A> prompt, although that is 260K instructions just to get to that point!
Now I have to insert my serial cog so that I can properly enter program names.
Currently DIR does not work properly but I think it's because of lacking a serial buffer.
I have found what I believe to be a bug in the P1 emulation for the cp (hl) incorrectly setting the flags. Need to do more testing on this.
I plug this tiny thing about 10mm sq but it's quite rigid. It's supersized as it has 8 * 8MB floppies/hdd on board
You mean 8,000 x 8MB floppies (if there was such a thing) or maybe you mean 80,000 x 800k floppies? If somebody had said that was possible back in the day I would have said they were crazy. But if they said it would sell for the price of a pizza and was the size of your thumbnail, I'd definitely steer clear of the kook.

Yes. I'd run like blazers
In 1976 a 10MB Disc Drive was the size of a washing machine and cost $16,000. No way could they put 1,000 of them into a 15x11x1mm piece of plastic for $10 in my lifetime. And fast too! The average access time to get on-track on those monsters was 45ms. By special tweeks I could read a 10MB drive contents in 1m45s but writing took 3m22s. There was no time to do anything with the data in that time tho.
just wanted to give you something to test with, which is sadly failing on @heaters ZiCog variant, I never got @pullmolls version running...
@"Peter Jakacki", yes it is quite fascinating running CP/M with @Cluso99's Ramblade (P1 with 512KB external Ram)
It supports 8 drives, has tons of software available and is the size of a matchbox. A lot of stuff works nicely via serial ansi terminal, wordstar works nicely, and even in usable speed.
Getting this on a P2 running would allow to even use MP/M with Bank switching and Multi User Support. It did mostly run on the P1, according to that really, really long thread I read thru multiple times. One need to bootstrap it from a running CP/M system.
Having one of those as "Network Server' between serial connected Client P2 could maybe provide a nice way to interconnect P2's, a simple spin (or TAQOZ) client could PIP files, read/write and also call cmdline orientated programs/batch files, whatever.
We could get access to Databases, Compilers, Scripting a shared file system, all of it just over 2 pins per client, serial to one central P2 connecting all the others.
And all of this with just P2's, no PC needed. I find this really intriguing.
Sure it is 'just' another emulation, a Z80 bytecode interpreter, like RISC-V from @ersmith, TAQOZ from @"Peter Jakacki" , SPIN2 from @cgracey but isn't that exactly where the propeller should shine?
So, please, please, please @Cluso99, hang in there and allow it to happen.

For those who have the P1 ZiCog files on microSD...
Here is the binary for trying out CPM2.2 on the P2
You can download it into the P2 using P2LOAD (available from/with Eric's Flexgui download).
The Z80/CPM emulation runs on the standard P62-P63 pins and at 115,200 baud. It's slower than usual because I have an inbuilt delay between instructions that I haven't removed yet. Also internally there is a lot of debug code that just isn't displaying.
Alternately, copy it after renaming as Z053A.BIX to the SD card, and run from the P2 ROM Debugger with
>ctl-D
which brings up the debugger (may need to do this twice???)
then
RZ053A.BIX<cr>
which will load and run the binary. Wait a few seconds and you should see the messages as shown in the previous post.
So how fast is your Z80 emulator on the P2, Cluso? At what frequency multiple would it be typically equivalent to a real Z80?
Eg. 50MHz P2 ~ 4MHz Z80, etc?
No idea
I don't even know how to do a comparison. I guess the best idea I could get is to compare the number of clocks on P1 compared to clocks on P2 for time to boot CPM.
And currently it's not optimised.

Some quick googleing finds some CP/M benchmark programs some guy compiled. A Commodore 128 apparently gets 85.5 Dhrystones/s. Not sure if it's the right kind of CP/M program though?

I've just tried it on a CPM emulator on my PC and both worked (altough DHRY.COM was unable to give a sensible result), so if they don't work on the P2, that might hint to a bug in the Z80 emulation?
mandelbr.com on P1 gives a message "Mandelbrotmenge - Start mit Enter" and after <enter> causes a halt probably as a result of an unimplemented instruction.
mandelbr.com on P2 gives a message "Not enough memory" "Program aborted" which is curious since I'm running a full 64KB RAM which gives about 61K for cpm programs. BIOS etc begins at $DC00. I have to presume it's an emulation error
If you want to check the card with the P2 remember that you can boot into TAQOZ, type MOUNT which will initialize the SD interface and mount the FAT32 filesystem. It reports back the card ID and you can type DIR to check it. If that works then it's not a formatting issue.
Comments
206,521 Z80 instructions have been emulated to get to this point!
Now that you have the A> prompt, where do you insert the floppy?
could you try those attached files on your P2 Z80 CP/M, both do fail on P1 Z80 CP/M on the Ramblade you send me.
please,
Mike

@Wuerfel_21,
any chance you can find the sources?
The 128 has a Z80 for CP/M
OBJ sd : "_SD_Equ" ' sd driver register & call equates card : "_SD_Code" ' sd driver pasm code to be relocated in hub (hubexec) Print : "_STD_IO" ' std input & output driverUsed the attached to load the binary using FastSpin and loadp2... Maybe I need to use PNut? Nope, same with PNut...
Might be an error reading the SD card. Try formatting and rewriting the SD card.
