Thread: write image.img to 8" floppydisk dosn't work

    Fritz,
    I wish I was that lucky to get the other image to work. It's close to the XER6 but cpmtools won't extract a file.
    I can get a directory listing that looks sane.

    Code:
    cpmls -f xer6 -D CPM-80_57K_V2.2_boots_on_Intel_MDS_DD.img

    But, as I said cpmls will not extract a file. I've overlooked something.

    Fritz,
    I've process the other two images and the files are located on dropbox. I was able to get all the information on the .IMD files,
    and extract the files. See the README.1st file.

    If you have cpmtools built with libdsk, libdsk's dsktrans can write the IMAGE directly to Floppy.


    Thanks.

    @Larry,

    great work.

    The floppy disks I send you the images about are now in the postage to the system owner. I added some usefull programms using 22disk to another disk and I'm looking forward if they boot well.
    My knowledge of cpmtools and libdsk isn't enough to write to floppydisk and of course I have the 8" diskdrives added to an msdos-computer.
    I don't have a linux system with isa slots for the AHA1522B (connecting the 8" drive for FM/MFM) at the moment.


    Thanks.

    For the DSDD Image: CPM-80_57K_V2.2_boots_on_Intel_MDS_DD.img
    The following commands work: (I had forgotten to use the rawob, rawoo, or logical to specify exactly)

    Code:
    cpmls -f xer6 -D CPM-80_57K_V2.2_boots_on_Intel_MDS_DD.img
    cpmls -f xer6 -T logical,xer6 -D CPM-80_57K_V2.2_boots_on_Intel_MDS_DD.img

    I believe I have to translate a short explanation from the system owner.

    From Franz Lange:

    I want to get my first CP/M computer up and running again, unfortunately, the boot disks have been lost.
    The computer could boot CP/M or Intel ISIS-II from 8 inch floppy disks. Floppy disks running on an Intel MDS800 or a Siemens SME800 should also work on my computer.
    My first CP/M computer is based on ECB cards. I have threaded the Z80 CPU myself. Memory cards were even threaded or bought as a blank card.
    I bought the floppy disk controller as a finished ECB bus Eurocard from Lakosa in Paderborn.
    The floppy controller is software compatible with the floppy controllers of the Intel MDS. It uses the same I/O address and the same command format.
    I was able to boot both ISIS-II and CP/M with my computer. Before booting, only a few bytes had to be changed in the boot monitor,
    to boot CP/M or ISIS. The details I can no longer understand, because I neither the sources nor the listing of my adapted boot monitor.
    The computer is connected to two Slim-Line 8-inch Tandon TM848E drives. One is still working. I can read and write individual sectors.

    ##################################################

    And success...

    The ISIS-II disks are booting, now we wait for the CP/M disk.
    The system hast no active cooling so it becomes hot an after some time it became unstable and must be reset. So there is more work to be done.

    From the floppies I send to Franz he made some nice boot able floppy disks with correct labels.

    That's quite a third-party disk controller! IIRC, the MDS-800 controller was a two-board affair with a separate channel board and and controller that used Intel 3000-series bit-slice logic. It ran very hot.

    I think that the native controller for the MDS-220 series was different. I recall that we had a 210 that used the 2-board Multibus M2FM controller added, as the 210 otherwise lacks a disk controller.

    The Series II systems had a standard single chip controller on the IOC card. One still needed the two board set to use M2FM. I forget if the one on the IOC was FM only or MFM and FM. People like Eric Smith would know ( he is on cctalk ).
    We used the M2FM cards in the lab when I was there, even in the Series II ( 210/220 ).
    Not every 8 inch floppy would run M2FM as I recall. The SA800s we used had a slightly different high frequency peaking in the preamp. ( I don't recall if it was a capacitor or a resistor difference ).

    We used the stock Shugart SA800 drives (we had two systems) and they worked just fine. Could be a matter of YMMV.

    The Series II IOC used the 8271 FDC, FM only. The 8272 came along much later. I believe that the Series III was also FM only--and of course, the Series 4 was 5.25".
