yes, thanks for the info.



the fpga is not an emulator   :)

My apologies.  I should have posted that I released version 2 of the fpga core for PCW and it includes all the following:


* Turbo support to 32Mhz
* Expanded memory support to a maximum of 2MB
* 3" and 3.5" disk support
* Dual disk drives
* PCW 8xxx and PCW9xxx model support
* All hardware Joysticks and Mice supported
* 4 colour mode support

I'm not sure you've got the model numbers right.
Code: [Select]
8256 / 8512: Dot-matrix PCWs with (usually) 180k boot drives. Boot sector checksum is 0FFh.
9256 / 10: Dot-matrix PCWs with 720k boot drives. Boot sector checksum is 0FFh.
9512 / 9512+: Daisywheel PCWs with 720k boot drives. Boot sector checksum is 01h.
So I suspect "9256 / 9512+" doesn't actually describe what it's doing.

Hi John


Thanks for the response.  Yes, you are correct that the names are misleading.


I only have two modes:
8256/8512 = A: 180K 3", B: 720K 3" (but can read 180K disks) - Checksum 0xFF
9256/9512 = A: 720K 3.5", B: 720K 3.5" - Checksum 0x01


I did struggle on exactly how to classify those two modes in the menu.  Showing the Checksum and the drive types would probably confuse non-hardcore Amstrad PCW users.


I have the disk configuration I do in 8256 mode because it is incredibly convenient.  You can leave a CPM disk in A: then just iterate through the library just swapping drive B:


Any ideas on a better naming convention given the above information?

I'd say "9512 / 9512+" for the configuration with checksum=1.

Ok, thanks for the feedback John


I'll change that now.  I'm working on a fix for the SymbOS issue.

Just a short question: is it possible to emulate a harddisc for the CP/M OS over the MISTcore / -hardware?

4 colour mode support
PCW with Audio AY (dk'Tronics) and Habisoft's ColorIn board support

GREAT !! enhanced PCW

This sounds pretty awesome, maybe something for uhmm Xmas?
Are there any limitations compared to real hardware?

... limitations compared to real hardware?
no HDD ; no FDD... only "virtual" DSKs...
and core autor said Symbos (cause ms-dos fat12 dsk? ) did not work.


[but colour & audio...  :o  it's "missing link" Arnold Number Two...] if NeptUno core port not come, I'll buy a MISTer too.
