Fed up of having to load up CP/M just in order to format a disk? This handy utility will format a disk to your choice of formats: System, Vendor. Data, IBM or a new BIGK. Unfortunately a small bug has crept into the tapedprogram that causes an error message to appear before it formats ?, disk. The offending line is 180. If you remove the command |DISC, @art$ from that line then all will be well. A menu will appear requesting you to choose the type of forniat^required; just follow the prompts and there should be no problem. BICK will format a disk to hold 206k. The first track will be formatted in,ordinary data format while the remaining ones will be formatted to a completely new specification. A file called BIGK will be written to tlxe disk; running this will allow you to get to all that extra storage space. All the conventional formats have nine sectors per track, except IBM which has eight. The BIGK format however has ten sectors per track - if each sector fiolds 0.5k of data, it is quite easy to see how the extra storage space is acquired. It is possible to use BIGK for loading and saving files under Amsdos - but not under CP/M.. You may also have difficulty transfering files from one format to another - this will be explained in a future article. The reason, briefly, is that the XPB (expanded disk parameter block) has been altered and will allow only reading of the BIGK format. If you follow the steps below, you should be able to transfer files by hand this is by no means idea^but will suffice for the time being. For basic file transfer, insert the source disk and then type, in direct mode: LOAD"Filename"Insert the destination disk and type: FOR t=0 TO 1:POKE &A8A8,+dr,&FF
POKE &A890+dr,&28:POKE &A895+dr, &D0
POKE &A89D+ dr,1: PoKE &A89F+dr,&30
POKE &A8A0+dr,&A:POKE &A8A2+dr ,&32
POKE &A8A3+dr,&E5:POKE &A841+dr, &20: NEXT tSAVE"filename" If you wish to read ordinary disks, you will have to enter the following: FOR t=&A890 to &A890+180:POKE t,0:NEXT tTo transfer a binary file, just load it into memory, then run the BIGK file, and save as normal.

Page créée en 315 millisecondes et consultée 1920 foisL'Amstrad CPC est une machine 8 bits à base d'un Z80 à 4MHz. Le premier de la gamme fut le CPC 464 en 1984, équipé d'un lecteur de cassettes intégré il se plaçait en concurrent du Commodore C64 beaucoup plus compliqué à utiliser et plus cher. Ce fut un réel succès et sorti cette même années le CPC 664 équipé d'un lecteur de disquettes trois pouces intégré. Sa vie fut de courte durée puisqu'en 1985 il fut remplacé par le CPC 6128 qui était plus compact, plus soigné et surtout qui avait 128Ko de RAM au lieu de 64Ko. |
