ICOM FDOS-III for the Poly88

[atariquest]

Here is the macro assembler's manual.

Thanks Marvin! I have posted the manual on deramp.com with other the other FDOS manuals. Great to fill in this missing documentation.

I looked at my other iCOM manuals. I have been able to find copies of them online. All my manuals are iCOM branded, whereas some online copies are Pertec. Other than that, there are no substantive differences.

Since it’s hard to come by a working FD-360 or FD-3712 setup, you can run original 8” FDOS disks using the Altair FDC+ and a couple of Shugart 800 drives or a couple of 5.25” HD drives (like the Teac 55-GFR). I’ll be making a video and posting more information soon.

Hi,

Is there any kind of FDC+ that is literally just the controller portion, and not integrated as an S100 bus card?

I have an RCA Microboard system (the RCA MS2000) that has a 50 pin "PERTEC" floppy interface, designed for use with FD3712/FD3812 systems. I imagine i may not be alone in the desire to have some kind of FD3712 "emulator" setup for non-S100 bus systems. Of course such a system could still integrate with an S100 system via the original floppy interface card.

I’ve had this project in mind for many years. A standalone controller that duplicates the iCOM parallel interface on one side and then provides a standard 50 pin and 34 pin Shugart interface on the other side for 8” floppy drives or 5.25” HD floppy drives (look like 8” drives to the controller). To allow the parallel interface side to be easily configurable to most any parallel interface board, a small “hat” board is used to connect the host ribbon cable to headers on the new controller board. The hat board, in turn, is what converts the pinout of the incoming ribbon cable(s) to match the pin order of the headers on the controller.

I have the sources for FDOS-M EPROMS as its in the manual I have.
I'll look and see what in the history. Hex files I can work with.

Hello - still looking to get copies of any manuals you have that address FDOS-M as they sound like the only 5.25” specific manuals I’ve ever run across. What manuals do you have for FDOS software and hardware? Thanks!
