Re: Wanted: IBM PC compatible 8 or 16 bit Arcnet cards
I'll be following your progress with interest, I just installed Coax into the walls of my computer playhouse so I can ARCNet with my S-100 system. I have an ARCNet packet sniffer that can be loaned out if you would find it helpful. - Jonathan On Sunday, December 12, 2021, 11:00:03 AM MST, wrote: Send cctalk mailing list submissions to cctalk@classiccmp.org To subscribe or unsubscribe via the World Wide Web, visit http://www.classiccmp.org/mailman/listinfo/cctalk or, via email, send a message with subject or body 'help' to cctalk-requ...@classiccmp.org You can reach the person managing the list at cctalk-ow...@classiccmp.org When replying, please edit your Subject line so it is more specific than "Re: Contents of cctalk digest..."

Re: Diversified Technology CAT904 80286 single board PC
I've got a Diversified Tech 286 SBC as well and was able to switch to 3.5 floppies by modifying the BIOS settings. Mine has the Dallas Real Time Clock chip and the battery was dead so the BIOS settings weren't preserved after a reboot. Fortunately I obtained a replacement chip available on ebay to fix that issue. I haven't got a manual to share, but it's a neat little board.

Concurrent Controls Multiuser DOS
I'm researching Multiuser DOS out of my own interest. A version made by Concurrent Controls specifically. However, I have been unable to find documentation on it to satisfy my curiosity on how it works and how it is configured. They must have somehow broken the 640K barrier or virtualized each user session, I'd like to understand it better. What were it's limitations, I'm guessing that each user didn't get direct access to hardware. Anyone out there have a document or experience with it? Thanks, Jonathan

Re: ArcNet board Wanted, Intercontinental Micro
Thank you Richard, yes if you're willing to check your inventory of ARCnet cards I may find something useful. ARCnet boards are pretty much all the same, but this particular one I'm hunting for from Intercontinental Micro is compatible with a special boot ROM I have that promises to unlock wonders unknown to the world since 1987. Maybe I exaggerate a little bit, but I do appreciate you checking. Jonathan

Re: TurboDOS for S-100, IMS or L/F Technologies
Yes, I was able to determine that the TurboDOS 1.41c disks which would complete my particular setup do exist and that they are in good hands, however I have not been able to get copies of the disks as of yet. I'm hoping that patience will prevail and perhaps another copy will turn up or the copies that I know about might someday become available. The 16-bit 1.43 version that you need is readily available as 5.25" disk images. I've got copies of them and they work well. If you need it on 8" floppy, I can probably convert them using my IMS system to write them to 8". Getting a system up and running is not that difficult, I can guide you through if there's any trouble. Jonathan __ did anything more ever turn up? I'd like to try getting a 16-bit 1.43 running, there is a set of disks on ebay, but the seller has blocked me https://www.ebay.com/itm/193098921854 On 6/28/19 7:17 PM, Jonathan Haddox via cctalk wrote: > Just sending a thanks for the replies from various folks on this list.
