Title: how to format a new 3" disc, without CPM Disk, CPC6128
Post by: davebirl on 00:02, 20 March 19
Hi Folks,


As a kid I used to have a CPC464 and recently got myself a CPC6128.



I have an M4 board and just bought myself a new/old stock 3" disc. I would like to format it and test it out etc.
I've tried loading CPM into ROM but I cannot run the disckit3 command and when I load up the CPM dsk files onto the M4 board disckit3 also does not run from there.
Is there anyway I can format this 3" disc?


Cheers


Dave

Load a rom that has disk format capabilities.
I believe utopia can do it.
Try parados as well

How to format a disc (M4 is connected):

1. Install X-DDOS (ROM number lower than M4), then use !FORMAT,1

2. Install ParaDOS (ROM number lower than M4), then use !DRIVE to enter menu (Shift and Control keys bring you to different menu levels)
3. Install FutureOS, format disc

4. Get tools from cpc-power to format a disc

Hi Dave,

Install the ParaDOS rom - ParaDOS will format and also verify the disc - have a look at the manual here:

Parados. The rest are just not as good! I have Parados installed internally on all my cpcs. If you need a rom burning let me know and I'll post you one.

I like parados but some games don't.
I use the ROM version of Discology.

Do you have some examples of the games that you have a problem with Parados ?


Thanks.  Ray

Can't remember many but Double Dragon is one and from utilities discology.
I had the real ROM a couple of years ago and it was great but a real pain for games.
Same results with emulation.

Otherwise with only BASIC, you can type this little program, it will format the floppy !
Better to save it somewhere before executing as if I can recall, you'll have to reset the CPC once done :) :


Quote1 MODE 2 : PRINT "Get the floppy containing this program out of the disc drive and insert the one to format, don't forget to put tape over the protection hole if it's a 3.5 HD floppy"
2 INPUT "Do you really want to format this disc ? 'y' for yes and 'n' for  no",choice$
3 IF choice$ = "y" THEN GOTO 10 ELSE GOTO 4
4 END
10 DATA 11,00,00,21,20,A5,06,09,72,23,23,23,23,10,F9,21,20,A5,D5,DF,1D,A5,D1,14,7A,FE,2A,20,E6,42,C0,07,00,00,C1,02,00,00,C6,02,00,00,C2,02,00,00,C7,02,00,00,C3,02,00,00,C8,02,00,00,C4,02,00,00,C9,02,00,00,C5,02,00,00
20 MEMORY &A4FF : FOR i=&A500 TO &A545 : READ a$:POKE i,VAL(chr$(38)+a$) : NEXT
30 CALL &A500

Line 30 must be CALL &A500


There is no line 11, that's part of line 10.

Works fine, the only problem was in winape's autotype.
At line 3 ( "y" ) it replaced that characters with something else.

Wlll work fine as long as the area from &A50 to &A500 only contain &00 Bytes  ;) :)

Dunno, here formats the disk fine.

It put's the machine code in RAM beginning at address &A500, but then it jumps to address &A50. So this is a type (I guess), just on "0" was forgotten. The right address it &A500 to jump too.


It will probably not matter if you just have switched on your CPC, but after working a bit with it the wrong address could cause a crash.

Indeed, there's no line 11, it's just the forum that jumps a line as there's no spaces in that line and it's too long. And you're correct as well with the &A500, an involontary backspace happened :p. I edited the post, thanks !

There is a crash after the format procedure but I thought this was normal.
Anyway after that the disk is formatted.
