 Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me. |

Looks like I have a steepish (re-)learning curve ahead of me. I'm also building a N8VEM ZETA SBC. Still waiting on parts, drat it. Futurlec seems to be very slow. Regards, Bob Devries Dalby, QLD, Australia |

morning, Ken. Just a quick couple of questions... What is the programme needed to copy files to/from a CP/M disk image file? Is it possible to use different sized (i.e. from a different emulator) disk image files on the Maximite CP/M emulator? Regards, Bob Devries Dalby, QLD, Australia |

To copy files use PIP like pip c:=pip.com http://userweb.port.ac.uk/~msm/interests/chistory/documents/ cpm-22-manual/ch1.html#Section_1.6.4 have not tried other disk images yet ken |

Hi Ken, sorry, I didn't make that clear. Are you able to copy files to/from the disk image file in Windows? I have seen something called CPMTOOLS, but I don't know enough about CP/M disk formats for that to be useful. Regards, Bob Devries Dalby, QLD, Australia |

Forgot one more thing with cpmtools you will need to tell it the disk format with -f ibm-3740 ken |

Thanks Ken, that's made it clearer. Does that only apply to the images in DRIVEA and DRIVEB, or is CPMTOOLS smart enough to work out the rest? I have a disk image which has DBASEII on it. The image is 1113536 bytes long. The first $66C3 (26307) bytes are all $E5, and then there's a directory entry. First byte = $00 (user number, I think?) then the filename. Is it possible to get the files off it? I tried to make it drivei.cpm, but no go. Is it possible to change the drive statistics from the command line in CP/M? Regards, Bob Devries Dalby, QLD, Australia |

i have a wordstar disk that's the same just start working on it to figure out the format http://www.autometer.de/unix4fun/z80pack/index.html lots of dsk images there |

Ken, I worked out that the dbase.dsk image file was from the ALTAIR32 emulator. I loaded that up, and I can access the disk image. STAT DSK: gives the following parameters: B: Drive Characteristics 2040: 128 Byte Record Capacity 255: Kilobyte Drive Capacity 256: 32 Byte Directory Entries 256: Checked Directory Entries 128: Records/ Extent 8: Records/ Block 32: Sectors/ Track 6: Reserved Tracks Hope that helps. Regards, Bob Devries Dalby, QLD, Australia |

Hi all, I love old tech (but have never used it because I'm under 20!) and eagerly installed CP/M, but I'll be going back to MMBASIC until I can figure out how to use it (I'll get the Windows emulator for it and have a play.) At the moment I'm trying to write Conway's Game Of Life in MMBASIC, which will be pretty neat when I finally do it. Capacitance is futile - roll on 2012! |

Hi Ken I have formated an 8GB CD Sim card, copied drivea.cpm, drive b.cpm drivec.cpm and drivei.cpm over to the card. I have 'flashed' the maximite with your Hex code and installed teh CD Sim card. On power up, the good news is that it works! I get your banner, and can 'DIR' drive A: and see files there, however when I enter: user 8 for example, I cannot see drive I, or any of the other files on the CD Card. Any thoughts as to what I'm doing wrong? I have checked the CD card again, and the .cpm files are on the card. All assistance apprecaited. Kind regards Brendan |

Try using a 2GB or smaller card, formatted for FAT16. Once that works, you can try larger cards, SDHC, and the FAT32 filesystem. |

Brendan, a short time ago I reported the same problem to Ken, and he replied that he had inadvertently included a blank drivei.cpm file. He provided a link to a replacement. Have a read a few messages back up the list. Regards, Bob Devries Dalby, QLD, Australia |

Hello guys, you may be interested in my PC/M emulator, running on PIC32. Core of emulator consists of PIC32 and SPI FLASH - in fact it is all what you need to get CP/M running. There is also one PIC16 scanning keyboard and another one PIC18 making VT100 compatible terminal for 240x128 pixel LCD. This all makes relativley low power CP/M device intended to form kind of "CP/M laptop". A few more details and link to photogallery is avaliable at http://jaromir.xf.cz/, but there are no sources yet - it is a bit messy now. If somebody would be interested, I may send it by e-mail, but at your own risk. |
