Does anyone have image files from the floppy disks that came with the IBS AP14 floppy controller board?
IBS AP14 is a disk controller interface card for the Apple II computer, which was developed and distributed in the 80s by the company IBS Computertechnik in Bielefeld, Germany.
IBS AP14 can control up to 10 drives on a single controller (4 x 8 '' drives + 4 x 5.25 '' drives + 2 x genuine Apple drives). Disk formatting is in IBM format, which makes it easier to exchange disk data with other computers.
IBS AP14 came with patch disk software to use the operating systems DOS 3.3, CP / M 2.2, UCSD Pascal 1.1 and ProDOS of the Apple II computer. In addition, a test disk software for testing components of the interface card is included.
I fixed a bunch of hardware bugs on my personal IBS AP14 card and I want to test it now. For this I need the original patch discs from IBS. Especially from the IBS test disk I promise a lot, because the AP14 card is equipped with a complex SAB1793 floppy disk controller chip and a MC6844 direct memory access controller chip.
Unfortunately, the disk image files on the appleii-box website (IBS AP14 Industrial Drives Controller) do not work, since most are only filled with 00 bytes.
I looked at all the disk image files with a hex editor:
AP14A.dsk - contains executable binary code (OK) [AP14 FORMATTER VERSION 1.1 15.9.85]
AP14B.dsk - contains only 00 bytes (NOT OK)
AP14CPM.dsk - contains only 00 bytes (NOT OK)
AP14CPM2.dsk - contains only 00 bytes (NOT OK)
AP14PRODOS.dsk - contains only 00 bytes (NOT OK)
AP14PRODOSB.dsk - contains only 00 bytes (NOT OK)
AP14TEST1.dsk - contains only 00 bytes (NOT OK)
An image file from the EPROM on the IBS AP14 card with the boot programs for the Apple and industrial drives also helps me with my tests.
Many Thanks. Kind Regards.
