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 Universal Floppy Controller Datasheet
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.

I believe that this is the ROM image you are asking for... even that the file name is written incorrectly as "IBS AP-41 ROM.bin" instead of "IBS AP-14 ROM.bin.

This EPROM seems to be bad before reading. Some bytes are good, a lot are bad. I think this is no valid code.
I found a version which is probably in good condition. But I haven't tested it:

If this is working, please give a response

AP14 is in the last part of page together with links to disk images
As mentioned before every image is empty and filled with '0' except the first one (AP14A.dsk).

Hello Ralf,
i didn't recognize page of my site to be the source you used.
I'll check within next 48 hours and correct that.

Too bad, even after more than a year, IBS AP14 disk images have not be done on the page http://www.appleii-box.de/003_appleboxdownload.htm. The broken disk images AP14B.dsk, AP14CPM.dsk, AP14CPM2.dsk, AP14PRODOS.dsk, AP14PRODOSB.dsk and AP14TEST1.dsk are still embedded there. Is there any chance that they will be exchanged for working disk images? SpeedyG, do you have the right patch disk software for the IBS AP14 floppy controller board? Any non-fake answer is welcome.
Hello together,
there were some cards from German vendors, which base on the same hardware:
Basis Floppy Disk Card
Ehring FDC4 Card
IBS AP14 Card
And a second group:
IBS AP41 Card
IBS AP53 Card
The AP14 is not the AP41, they are different. I am also interested in a set working AP14 Software Disks.
Best regards
Wenn Jemanden die ganz genauen Unterschiede interessieren:
Ehring FDC4 Disk Controller ist hardwareseitig identisch mit IBS AP41 und IBS AP53. Die Platinen sehen auch identisch aus. Die 256 Bytes I/O ROMs unterscheiden sich aber in ein paar Bytes bei allen drei.
Hardwareseitig sind 2 x Disk ][ und ein 34-poliger Anschluss für 5.25" Industrielaufwerke vorhanden. Doppelseitiger Betrieb wird unterstützt, softwareseitig bei allen drei identisch realisiert.
Alle drei haben keine 2 KB Firmware.
Der Basis 108 Disk Controller hat das gleiche 256 Bytes I/O ROM wie der IBS AP41 Controller, hat aber keinen 34-poligen Anschluss für 5.25" Industrielaufwerke, sondern nur 2 x Disk ][.
IBS AP14 hat das gleiche 256 Bytes I/O ROM wie der Basis 108 Disk Controller. zusätzlich sind aber 2 KB Firmware vorhanden, die es beim Basis 108 Controller und den drei Erstgenannten nicht gibt.
Der IBS AP14 beinhaltet zwei Funktionen auf einer Karte: Einen Apple Disk ][ kompatiblen Controller ohne neue Funktionen sowie einen Shugart Bus Controller für 5.25" und 8" Industrielaufwerke im
Standard IBM Format. Der Shugart Bus Controller enthält als Baustein einen SAB 1793 mit zusätzlichen DMA Baustein HD 6844. Softwareseitig wird nur ProDOS, CP/M und UCSD Pascal unterstützt
(es wird an den zusätzlichen Anschlüssen kein DOS 3.3 unterstützt). Die für den Shugart Bus Controller zusätzlichen I/O Adressen liegen im Bereich des Slot ROMs Cs00-CsFF.
Hardwareseitig ist ein 50-poliger Anschluss für 8" Industrielaufwerke und ein 34-poliger Anschluss für 5.25" Industrielaufwerke vorhanden sowie 2 x Disk ][.
Dann gibt es noch den Erphi AFDC2 Disk Controller, der hat ebenfalls 2 KB Firmware und patscht die eingelgten Disketten automatisch (sollte zumindest so sein).
Hardwareseitig sind 2 x Disk ][ und ein 34-poliger Anschluss für 5.25" Industrielaufwerke vorhanden. Doppelseitiger Betrieb wird unterstützt, softwareseitig anders realisiert als bei den drei oben.
Und dann gibt es noch den Rana Elite Controller. Dieser hat 4 x Disk ][ Anschlüsse, an denen auch spezielle Rana Elite Laufwerke angeschlossen werden konnten. Ein modifiziertes DOS 3.3 erlaubt
den Betrieb von 4 Laufwerken. Es gibt aber nur Unterstützung für DOS und CP/M. Im neuzeitlichen ProDOS FX wird dieser Controller ebenfalls unterstützt (aktuell im Betatest). Neben den üblichen
Disk ][ Laufwerken kann man von Rana noch folgende 5.25" Laufwerke (volle Bauhöhe) anschließen. Doppelseitiger Betrieb wird unterstützt, softwareseitig anders realisiert als bei den vier oben.
Rana Elite One = Single Sided 40 Tracks
Rana Elite Two = Double Sided 40 Tracks
Rana Elite Three = Double Sided 80 Tracks (die Ansteuerung der 80 Tracks funktioniert über half-track-Ansteuerung)
Wer dazu noch Fragen hat, immer her damit. In meinem Emulator werden alle genannten Karten und Laufwerke unterstützt. Allerdings keine Industrielaufwerke am IBS AP14, das macht im Emulator
nicht ganz so viel Sinn. Im 8" Bereich unterstützte ich den SVA 8" Controller und alles Andere macht man über Apple-kompatible 40-160 Track Floppy Disks oder ProDOS HardDisk Images.
If anyone is interested in the exact differences:
The Ehring FDC4 disk controller is identical in hardware to the IBS AP41 and IBS AP53. The boards also look identical. However, the 256-byte I/O ROMs differ by a few bytes on all three.On the hardware side, there are two Disk ]['s and a 34-pin connector for 5.25" industrial drives. Double-sided operation is supported, and the software is identical on all three.None of the three have 2 KB firmware.
The Basis 108 disk controller has the same 256-byte I/O ROM as the IBS AP41 controller, but does not have a 34-pin connector for 5.25" industrial drives, only two Disk ]['s.
The IBS AP14 has the same 256-byte I/O ROM as the Basis 108 disk controller. However, an additional 2 KB of firmware is available, which is not available on the Basis 108 controller and the first three mentioned.The IBS AP14 contains two functions on one card: an Apple Disk ][ compatible controller without any new features, and a Shugart Bus Controller for 5.25" and 8" industrial drives in thestandard IBM format. The Shugart Bus Controller contains a SAB 1793 chip with an additional HD 6844 DMA chip. On the software side, only ProDOS, CP/M, and UCSD Pascal are supported(DOS 3.3 is not supported on the additional ports). The additional I/O addresses for the Shugart Bus Controller are in the range of the slot ROMs Cs00-CsFF.On the hardware side, there is a 50-pin connector for 8" industrial drives and a 34-pin connector for 5.25" industrial drives, as well as 2 x Disk ][.
Then there's the Erphi AFDC2 disk controller, which also has 2 KB firmware and automatically patches inserted disks (at least, that's how it should be).On the hardware side, there are 2 Disk ][ connectors and a 34-pin connector for 5.25" industrial drives. Double-sided operation is supported, but the software implementation is different than the three above.
And then there's the Rana Elite controller. This has 4 Disk ][ connectors, to which special Rana Elite drives could also be connected. A modified DOS 3.3 allowsthe operation of 4 drives. However, it only supports DOS and CP/M. This controller is also supported in the modern ProDOS FX (currently in beta testing). In addition to the usualDisk ][ drives, the following 5.25" Rana drives (full height) can also be connected. Double-sided operation is supported, but the software implementation is different than the four above.
Rana Elite One = Single-Sided 40 TracksRana Elite Two = Double-Sided 40 TracksRana Elite Three = Double-Sided 80 Tracks (the 80 tracks are controlled via half-track control)
If you have any further questions, please let me know. All of the cards and drives mentioned are supported in my emulator. However, I don't support industrial drives on the IBS AP14, which doesn't make much sense in the emulator. For the 8" drive, I support the SVA 8" controller, and everything else is done via Apple-compatible 40-160 track floppy disks or ProDOS hard disk images.
