+InsaneMultitasker Posted August 23, 2019 Share Posted August 23, 2019 Sometimes you just have to own a piece of hardware like a ramdisk to experience and understand why it is so cool. 2 1 Quote Link to comment Share on other sites More sharing options...
GDMike Posted August 25, 2019 Share Posted August 25, 2019 It makes writing and assembly go smoother..even though we have classic 99...it's just not the same. Quote Link to comment Share on other sites More sharing options...

GDMike Posted September 20, 2019 Share Posted September 20, 2019 How is your project on these going? I hope you are making good progress. I think the last time I used a RD. Probably 1988.. I always thought how these should be standard for PEBs. 1 Quote Link to comment Share on other sites More sharing options...
+Ksarul Posted September 20, 2019 Author Share Posted September 20, 2019 My test boards are on order and should be arriving in about two weeks, based on past experiences with the board house I use. I have all of the parts on hand to build three or four of them (the Memory chips are the only chip in limited supply right now, as my stock of those was sufficient to keep SAMS boards in stock--and each of these RAMDISKS eats a lot more of them). I have also finished an updated manual which I will validate by using it to guide my test builds (and before I release it into the wild). If all goes right during testing, I'll be ordering the production boards sometime in the October/November timeframe. I'll definitely know more by the time of the Chicago Faire. 3 Quote Link to comment Share on other sites More sharing options...

+9640News Posted September 25, 2019 Share Posted September 25, 2019 After reading things over in the PDF, what is the maximum capacity a Geneve can use? Can it use the full 8 MB's? 1 Quote Link to comment Share on other sites More sharing options...
+Ksarul Posted September 25, 2019 Author Share Posted September 25, 2019 From the user's standpoint, there is no difference between this RAM Disk and the HRD4000. TI users would use the same DSR, and Geneve users would use it the same way they use any other HRD. The Insane One could say more about overall capabilities of an HRD with a Geneve, as he integrated a lot of that capability into the recent MDOS releases. 1 Quote Link to comment Share on other sites More sharing options...
+InsaneMultitasker Posted September 25, 2019 Share Posted September 25, 2019 In a nutshell: TI: up to 10 x 800K ramdisks, using ROS 8.34 or above. 10 x 400K ramdisks using ROS 8.14F. Geneve: one 3.2MB RAMdisk using FORM3MEG //or// MDOS 7.00 allows both an 800K ramdisk (for booting) and the remaining space can be formatted to look like a hard drive (I have compiled all of MDOS on a RAMdisk). The latter option is delayed until I figure out what is wrong with MDOS 7.00... Jim, we should amend the Phoenix references as I don't think any of that works with the Geneve these days, save for the dual ramdisk option - and even that would need to be tested.

+Ksarul Posted September 26, 2019 Author Share Posted September 26, 2019 Thanks for the clarification, Tim. I'll have to build one and test it once they arrive in ten days or so. I agree that most of the Phoenix mod bits may not work with more recent versions of MDOS--but oddly enough (and based on what I've seen show up on eBay), there are still quite a few unmodified Geneves out there that aren't even capable of running MDOS 5 yet!

GDMike Posted September 28, 2019 Share Posted September 28, 2019 I just need one good, large, drive and then I'll be thanking the ramdisk God for quite a long time. Oh, and a couple blanks in case...hmm, which makes me wonder about sumpin. Jim, is it possible to make one as a sidecard for a NANOPEB? Just a question....

+Ksarul Posted September 29, 2019 Author Share Posted September 29, 2019 No way--too big without moving down to 3.3V SMT parts. . .and the Nano really doesn't like most other expansions. . . 1 Quote Link to comment Share on other sites More sharing options...
+Ksarul Posted September 29, 2019 Author Share Posted September 29, 2019 And note, these are the test boards I'm getting, to verify that my layout is good. A production order would follow that once any issues are quashed. . .and then I'll have to build a lot of them it seems--and that's a good thing too. 5 1 Quote Link to comment Share on other sites More sharing options...
