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.

Ok, thank you guys for the information! Today i finished the case for my external CMM2 Floppy Drive: Here some Pics: The next Step is to mount an IDE (40 Pin) Connector on the backside for the CMM2 Connection. Edited 2021-07-28 02:21 by Vampire05 |

It won't blow off the table anyway. :) Actually, I think it looks really neat. Your cutting and assembly look very precise. Mick Zilog Inside! nascom.info for Nascom & Gemini Preliminary MMBasic docs & my PCB designs |

Good work Vampire05, It won't be long before we hear the buzzing and sizzling of the floppy.... I remember the excitement when my old Acorn Atom was reading disks with a home-brew disk interface (5 1/4 back then). The 160k back ten was sufficient for 20-50 programs. Good that we have 1.44Mb now with the CMM2. Volhout Edited 2021-07-28 04:38 by Volhout PicomiteVGA PETSCII ROBOTS |

hi Guys, i have some problems with the xmodem transfer. here is the full basic file floppy.bas.zip the simple commands(dir, type, dump, rmdir, mkdir) works great but the xmodem command did not. what i do: i open the serial connection open "com1:115200, 256, get_floppy_output, 1" as #1 then i send the arduino dos command: print #1, "receive " + args(2) and then the xmodem send on cmm2: xmodem send "floppy.bas", #1 i tried also xmodem send "floppy.bas",1 xmodem send "floppy.bas" after longer waiting i see the empty file specified in args(2) is created on the floppy drive with the size 0. The cmm2 says "Remote did not respond". Any ideas how i can debug this problem? |
