CPC6128 - CP/M System Disks

[tubs74]

Hi, 

I wonder if anyone can shed some light - I've bought some system disks (3 sets), 

Set 1 - Purple (Amsoft), Side 1 CP/M System/Utilities, Side 2 Programming Utilities, Side 3 Dr Logo and Help, Side 4 CPM2.2 (no copright dates)
Set 2 - Aqua (Amsoft), Side 1 Loco Script Word Processor, Side 2 CP/M Plus, Side 3 Programming Utilities, Side 4, Dr Logo and Help (no copyright dates)
Set 3 (only 1 disk) Burgundy (Amstrad PLC) System/Utilities/Basic CP/M Plus - Copyright DR and Amstrad 85, 86, 87

Set 1, will boot from my CPC6128, and I can browse the files/run commands etc, so these are CPC6128 disks.
Set 2, from Amstrad basic on 6128 I can "cat" the disks, and get a listing.  Trying :cpm, i get retry, cancel, Ignore.  If I use the bootable CPM above and swap disks, I cannot do a DIR as I get retry/cancel/ignore.  I'm assuming maybe Aqua disks are PCW 8256/8512 disks
Set 3 (which is only one disk) won't cat from basic, and won't dir in CPM.  I'm assuming these are maybe the PCW9512?

Onto CP/M on the 6128, it boots with 61k available - on my spectrum +3 and C/PM I then have an M drive, that is the rest of the RAM - does CP/M on the 6128 have full access to 128k of RAM in a similar way?

Is there anyway to read the Aqua disks on the 6128, so I could look at loco script for example.

Was the CP/M+ the only version of CP/M available for the 6128, I'm assuming so as it's te last 8bit version, but I wonder if there were any imrovementys to CP/M Plus, that can be rolled back to the original CP/M plus that comes with the 6128?

61kB are in the second 64kB. In the first 64kB are CPM and screen.

There are some CPM modifications to support memory larger than 128kB.

There is CPM 2.2 for cpc

You can find an overview of PCW system disks here:

You are probably right that one set is 8000 series and the other 9000 series.

If I remember right Locoscript is not a CP/M application so it will not run on a 6128.

CP/M on the CPC should be a standard CP/M. Afaik they only adapted the parts which have to be adapted to make sure CP/M can run on that architecture. But of course the CPC still needs to be able to read the disk format. If you want to try out some other CP/M programs you probably have to transfer the files to a disk (image) that is supported on the CPC.

Yes, these disks are for the PCW System. There was a ,,type in" in a german journal to modify the CP/M 3.0 on a CPC6128 to read the PCW disks...

I will have a look...

So typing this exactly as it is, would create a little com program called c10pm3.ems that would allow me to read PCW disks?

It will patch the c10pm3.ems program, so you should do this with a copy of your CP/M disk.

One thing to consider: The patch replaces the configuration for the data format. That means CP/M will no longer be able to access disks in data format. You can only access CP/M system format disks and PCW disks if you boot CP/M with a patched c10pm3.ems

There are lots of apps for CP/M to change formats. Prominent is f.e. PARA 3.0, which supports nearly every format. There is also a nice DOS-COPY.
