Fwd: [Intel-devsys] irmx-80 diskettes

[craig andrews]

Mark,

Bill reminded me that you have a couple of versions of iRMX-80 on the archive.  I started perusing the files today …. Unfortunately I am way behind on using the software archive beyond just utilizing isis image disks.

(Simplest question first)

Looking at the disk set Bill got off of eBay (below)… and your iRMX files.  How are your files identified to which hardware platform they are for?  iSBX 80/10, 80/10b, 80/16, 80/20 etc?

Is there a readme recipe for getting your files back onto disk?  Are they all just binaries that can be copied using one’s favorite techniques or is there special conversion/hardware/handling required?

Thanks

Craig

Herb,

Indeed I have 5 each 8-inch disks here for RMX/80.

They are:
9500013-03 Ver 1.3, RMX/80 Real-time Multitasking executive for iSBC 80/20 and 80/20-4, SD.
9500018-03 Ver 1.3, RMX/80 Real-time Multitasking executive for iSBC 80/10, SD.
9700016-03, Ver 1.3, RMX/80 Real-time Multitasking executive for iSBC 80/20 and 80/20-4, DD.
9700020-03, Ver 1.3, RMX/80 Extensions for iSBC 80/10, iSBC 80/20, 80/20-4, and 80/30, DD.
9700021-03, Ver 1.3, RMX/80 Real-time Multitasking executive for iSBC 80/10, DD.

The SD disks should not be hard to copy.  The DD may be trickier.  I suspect they are in 3740 format SD but M2FM format DD.  I suspect I will need to write a program for the MDS II to create an image file on the PC.  I need to think about it some more, once I get the other board for Jon H. done and both tested. And I need to get some simulators to compile again and run, at least as far as the monitors are concerned.  I also need to get versions of CP/M-80 to run on the OEM simulators.  I also have several books I have collected to scan. So my queue is pretty full!

Biil, someone asked me about 8-inch diskettes with iRMX-80 on them. Of course I don't have them. So I started looking around for this. This doesn't seem to be available "on the Web" or among the intel-dev archives.

I searched your Intel Google Drive and then the archive of our Intel-dev discussion, for mention of iRMX-80. The only significant mention is your Sept 2018 purchase of five iRMX-80 diskettes from eBay. I didn't find subsequent email traffic on your results with those diskettes. And I don't see any iRMX80 disk images in any of the by-person folders in your Google drive. I checked Mark Ogden's gethub; no iRMX80 stuff there. One other reference but it seems a dead end. I'll detail it as a PS.

Bill, it is still a good "find" to have disks with iRMX-80. Thanks for spending the $$$ to get them. I know doing work is tough for you; there's no priority for this just because somebody asked me about it. But what's the status of those physical diskettes, and were you able to image them in some fashion?

Regards, Herb

PS: Jon Hales did something with a bunch of Intel diskette label-descriptions posted around Aug 2018. Mark Ogden commented about the list, and mentioned this:

950017.06 looks like irmx80 v2.4

I have no idea what Jon was doing. But I could not find a disk-image with that 950017.06 designation.

Since the iRMX-80 code came off ISIS disks, there are recipes to recreate the relevant disk images

@II-970032-02-D [EXC830-003] RMX 80 for iSBC 80_30 V1.3

@II-143042-002-D [EXC820-002] RMX-80 Demonstration Configuration Module

@II-950017-06-SB RMX-80 Extensions for iSBC 80-(10_20_20-4_30) V1.3

 

Looking at the description part of the filename I think some of the potential target hardware can be identified.

 

Note unlike the iRMX-86 I am not aware of a  bootable OS disk for iRMX-80

 

Regards

Mark

Thanks Mark,

I have a bit of hardware work to do yet but I will start piecing this together.  I am sure that I will need help down the road

Regards
