kogden Posted July 23, 2014 Share Posted July 23, 2014 Ah. Sounds pretty cool. I'm assuming the IMI drives are MFM? Kinda makes replacing a drive expensive if it keels over. Quote Link to comment Share on other sites More sharing options...
fibrewire Posted July 24, 2014 Author Share Posted July 24, 2014 (edited) Ah. Sounds pretty cool. I'm assuming the IMI drives are MFM? Kinda makes replacing a drive expensive if it keels over. It's not too bad. There are always plenty of corvus drives floating around, and used IMI drives can be found on eBay. Others have had luck using substitute hard disks. Check out THIS BROCHURE to see the models supported by the Corvus enclosure. Edited July 24, 2014 by fibrewire Quote Link to comment Share on other sites More sharing options...
fibrewire Posted August 13, 2015 Author Share Posted August 13, 2015 Just wanted to add a video to the collection. It's the corvus drive diagnostic software running on two daisy-chained drives. Enjoy! 3 Quote Link to comment Share on other sites More sharing options...

Kyle22 Posted January 16, 2016 Share Posted January 16, 2016 According to the Atari Historical Society http://firewi.com/ahs/corvus.html there is (was) a school using 64 800s all multiplexed to a Corvus. The school still exists, and I wonder if they still use their Atari stuff, or if they still have it (or know where it went). Fordham Prep: http://www.fordhamprep.org/ That's a nice lot of interfaces and multiplexers just waiting to be reverse-engineered and duplicated Quote Link to comment Share on other sites More sharing options...
fujidude Posted January 17, 2016 Share Posted January 17, 2016 It is very doubtful they still have it, much less use it. Quote Link to comment Share on other sites More sharing options...
Kyle22 Posted January 17, 2016 Share Posted January 17, 2016 I was hoping that someone who is interested in this, and is a friendly, outgoing type may contact them and ask. I'm not at all good at making 'cold' calls, and would get tongue tied and twisted if I even thought about contacting them.

Kyle22 Posted January 17, 2016 Share Posted January 17, 2016 (edited) That's a shame they threw them out... I guess it was wishful thinking... It sure would be nice to reproduce these, now that Avery has so kindly made it possible to use Corvus drives on XL/XEs in Altirra. It only requires a change in the software from PORTB to PORTA and PBCTL to PACTL. I have made the changes to the Corvus SYSGEN disk and boot disk, and it works in emulation with XL/XE. Sadly, I have no (physical) Corvus drive (of that type) to try it with on real hardware. Oh well, an interface will turn up that we can clone. Fibrewire kindly posted pictures, so that makes it easier to figure out what they're doing. There's only 10 TTL chips (IIRC) in the interface, so it shouldn't be that difficult to figure out. Thanks to anyone who can continue this project by posting pictures / schematics of their Corvus interface. Edit: Multiplexers too, and if anyone has a dump of the Integrator ROM, please post it here.

Kyle22 Posted June 4, 2016 Share Posted June 4, 2016 Has anyone found a ROM dump of the the Integrator? That is what I really want to see (and dis-assemble). Quote Link to comment Share on other sites More sharing options...
fibrewire Posted August 3, 2016 Author Share Posted August 3, 2016 (edited) Has anyone found a ROM dump of the the Integrator? That is what I really want to see (and dis-assemble). When i talked to david, he said there is no difference between the ADS Integrator and the RAMROD card made by Newell. The first edition ADS integrator was special, but then experienced legal issues from some unnamed entity. A few second-generation "ADS Integrator" boards were all Newell RAMROD boards with the same boot code that is used on the Corvus boot floppy, available for download on this thread.

This is good news since Wes Newell donated most Newell products to public domain. I'm not certain this included the RAMROD MMOS personality board, it seems likely though since he did place the manual into the PD. https://archive.org/details/NewellIndustriesRAMRODMMOSManual Quote Link to comment Share on other sites More sharing options...

I was looking for a ROM dump where the Corvus code is already integrated into the OS. Then I want to dis-integrate it and re-integrate it into different (XL) OSs.

He said it's just a memory location it looks for on boot changed to access the loader on the corvus drive. corvus_boot.atr 2 Quote Link to comment Share on other sites More sharing options...
