+Ksarul Posted August 16, 2019 Share Posted August 16, 2019 I've been working on this mostly in the background, but it has finally reached the point where I need to order some test boards to make sure I have the final layout right. These boards will be capable of between 2M and 8M without chip stacking. Assuming that effort works out without too many issues, I have some community questions. Is there a preference for bare boards, for fully assembled boards, or both? The second question is about interest: what is the level of community interest in a new run of Horizon boards? Interest levels expressed here will let me know about how many to order once I've completed initial testing. The "B" designation mostly identifies boards as belonging to the current run, as there are only a few minor layout changes (in the battery pack area) and some better component identification on the board to help simplify assembly. 4 Quote Link to comment Share on other sites More sharing options...
Fritz442 Posted August 16, 2019 Share Posted August 16, 2019 (edited) I would prefer a bare boards for building. 3-4 boards. Edited August 16, 2019 by Fritz442 2 Quote Link to comment Share on other sites More sharing options...
Shift838 Posted August 16, 2019 Share Posted August 16, 2019 some users may not want to assemble and some of us would. Is the HRD going to be Geneve compatible too? i would be interested in a couple 2 1 Quote Link to comment Share on other sites More sharing options...
+InsaneMultitasker Posted August 16, 2019 Share Posted August 16, 2019 Sounds like you are going to use the 512K chips vs the 1/2/4mb chips. Can you share some specifics about the board and circuitry? Just some basic rambling ... My take on a new/updated ramdisk would be to keep it simple from both a hardware and software perspective. Ditch the RAMBO logic - it's pretty much useless/unused. If you are going for 8MB max, that would allow for 10 x 800K ramdisks on the TI, so no need for the dual ramdisk logic. The Geneve doesn't need or use the Phoenix mod so ditch that too. Any extra logic just adds to the pain of troubleshooting down the road. As a Geneve user, 12MB is the sweet spot (16mb probably the max) for ramdisk harddrive. There is a point of diminishing return on both the TI and Geneve, especially if and when you need to reload it. 2 1 Quote Link to comment Share on other sites More sharing options...
GDMike Posted August 16, 2019 Share Posted August 16, 2019 (edited) I've still got a handful of 32k, 8k SRAMs... I'm hoping I can still use em.. BUT oh well..I'd like 3-4, can you add more than 1 card in a PEB? Edited August 16, 2019 by GDMike 1 Quote Link to comment Share on other sites More sharing options...

peterfleeman Posted August 16, 2019 Share Posted August 16, 2019 (edited) I would love 3 unbuilt. I like that you’re naming it 4000B similar to the 3000B. Amazing that the series continues to develop. Thank you! What will you begin the serial numbering with? Do we know how many HRD 4000 boards were made?

+Ksarul Posted August 17, 2019 Author Share Posted August 17, 2019 Per Bud Mills in one of my conversations with him on the subject, there are not a lot of HRD 4000 boards out there, as he only had 250-300 of them made. I have #4128 here at the house (as a bare board). That said, the numbering will start with #4301 to guarantee that it stays in sequence. This board is following the original naming convention as it is only a minor modification to its predecessor (like the relationship between the 3000 and the 3000B). 3 Quote Link to comment Share on other sites More sharing options...

I'm wondering how much faster it is than the TIPI or the stuff I have stored on the FinalGROM. Both those device are pretty dang fast, so I'm not sure if I'd gain much for my specific setup. Are there any programs that are specifically designed to use it or have much improved specs when running out of it? Quote Link to comment Share on other sites More sharing options...

Are there any programs that are specifically designed to use it or have much improved specs when running out of it? Certainly true. I have a TIPI and a few mega carts but it's nice to have some of the older hardware when you need to test/build software for compatibility. Also, echoing Shift838, it's just plain cool and it's encouraging that there are still so many folks out there in TI land that continue to be creative. It's all good! 3 Quote Link to comment Share on other sites More sharing options...
Opry99er Posted August 23, 2019 Share Posted August 23, 2019 Damnit.... I'm in for one assembled and one bare board. :D This is the best TI news in a long time, Sir Jim. :) I am glad to see it has progressed this far!!! 2 1 Quote Link to comment Share on other sites More sharing options...
