Do you want me to look up the small DSR I wrote, that is compatible with the p-system? Or some verbal description? Both, maybe? Here's a link to a post where I described what the issue is. Ah, right under my nose, so to speak. I will post a response in the development topic. I found my notes and what might be as solution for the PCODE system, provided my assumptions are correct.

+InsaneMultitasker Posted September 13, 2023 Share Posted September 13, 2023 Updated Horizon Ramdisk User Manual, with a copy uploaded to Github. The next ROS and/or CFG release will be version 8.43, to address a few of the logged issues since 8.42c. And to loosely paraphrase Scotty, there will be "no bloody a,b,c or d" nor other letters of the alphabet added to future version numbers.

NewcomerTI Posted September 15, 2023 Share Posted September 15, 2023 This may have been asked but can I use AAA NiMH batteries in place of NiCAD ones on the board? I’m not quite there yet but wanted to get anyone’s take on their use in this application. thank you in advance Quote Link to comment Share on other sites More sharing options...
+Ksarul Posted September 16, 2023 Author Share Posted September 16, 2023 The voltage requirements for the charging circuit are the same, so they shouldn't cause you any issues. 9 hours ago, NewcomerTI said: This may have been asked but can I use AAA NiMH batteries in place of NiCAD ones on the board?

+InsaneMultitasker Posted September 23, 2023 Share Posted September 23, 2023 I've been asked about the Scotty reference; here is the relevant clip from Star Trek The Next Generation episode Relics. I have fond memories of meeting Mr. Doohan at a Gencon convention in Milwaukee, where he stayed 45+ minutes after closing to see all of us who were still waiting in line to meet him. I have the card and photo he signed that day. Such a gracious person. 4 Quote Link to comment Share on other sites More sharing options...

NewcomerTI Posted October 2, 2023 Share Posted October 2, 2023 Now I smoke tested my bare board when said to in the construction manual and I didn’t let any smoke out of the PEB or the card - so I started populating the chips and getting ready to run the MEMTEST. I saw the MEMTEST folder on the ftp site and downloaded it. I need some instruction on what file to run - perhaps a step by step since I’m somewhat of newbie at this sort of thing. Run on EA5 ??? RTEA_HRX I’m assuming. I tried and it errored - perhaps I don’t have the needed file yet. Help is needed and appreciated! Quote Link to comment Share on other sites More sharing options...
NewcomerTI Posted October 9, 2023 Share Posted October 9, 2023 I populated the board with all the chips and got the console turned on and in running cfg1 I get the unit to recognize the Horizon card only it won’t load the ROS. Something on the board seems to be hanging it up to recognize the disk controller and RS232/pio boards. When you turn the switch off to make it invisible it ‘sees’ the other boards. I don’t think I have the ROS842 file loaded correctly or it wouldn’t behave like this since my other two RAM boards don’t handshake with the system as this one does. They show the other boards ‘ok’! The other boards also load the ROS completely as the manual explains and ‘work’. Likely I’m not loading something off my disks in the proper sequence - so any help would be appreciated and might make this RAM board install go smoothly. Incidentally, the front LED on the RAM card illuminates steadily after accessing the proper drive number(s) but Errors out in the screens then reports ‘ No ROS loaded ‘ Quote Link to comment Share on other sites More sharing options...
+InsaneMultitasker Posted October 9, 2023 Share Posted October 9, 2023 Please be aware that your CFG program is one or two revisions behind, based on the date shown in the screenshot. See the link below to the 27 March 2020 release in the first post. I doubt the older CFG has anything to do with what looks like a hardware issue, but it can't hurt to test with the most recent software. What other cards are in your system besides this naughty Ramdisk? 1 Quote Link to comment Share on other sites More sharing options...
NewcomerTI Posted October 9, 2023 Share Posted October 9, 2023 There are a couple of cards in the PEB that I purchased back from Cecure when I upgraded to a PEB back in the day. A MBP clock is in the one system and the rs232 card and floppy disk controller. The other system just has a floppy controller, rs232 card and 32 k memory card until I upgrade the HRD 4000b with the chip once I get things sorted with the card. 1 Quote Link to comment Share on other sites More sharing options...

Seems like a simple enough configuration to test the Horizon. Check the chips for correct orientation and inspect for any missing or wrongly-installed components. @FALCOR4 or @Ksarul may have some better suggestions related to why this card seems visible at all times. In the meantime, be sure to grab the latest software. I'll be releasing a new CFG soon, but it doesn't contain any fixes that will benefit your described systems. 2 Quote Link to comment Share on other sites More sharing options...
NewcomerTI Posted Monday at 02:04 PM Share Posted Monday at 02:04 PM Making some progress. Still card is visible ‘all’ the time but the extraneous or ‘phantom’ card addresses are gone. CFG1 when ran gives two scenarios - it will hang the system on the PEB with the TI controller - the other system with the Corcomp DS DD controller performs a system restart. But will not load a ROS.

The Geneve rompage entry should not be there for a /4a system. What cards were in the PEB when you took the picture. 1 Quote Link to comment Share on other sites More sharing options...
NewcomerTI Posted Monday at 03:24 PM Share Posted Monday at 03:24 PM The RS232 and disk controller show up with the RAM card off. Its when the RAM card is on that the Geneve ROM page shows that it’s in the ‘system’. Quote Link to comment Share on other sites More sharing options...

NewcomerTI Posted Monday at 05:42 PM Share Posted Monday at 05:42 PM I have the jumpers set the way my other HRD 4000B is set, so no, the card is not set up in split mode. I’ll double check the solder joints around the jumpers though. Thanks for the help! Quote Link to comment Share on other sites More sharing options...
+InsaneMultitasker Posted Tuesday at 01:37 AM Share Posted Tuesday at 01:37 AM The Geneve card type won't show up except for a few conditions where it senses RAM where ROM is typically found (address space >0000->1FFF) AND finds a specific value at >8002. Check the LS244 chips for any shorts or opens. 1 Quote Link to comment Share on other sites More sharing options...
NewcomerTI Posted Tuesday at 03:24 AM Share Posted Tuesday at 03:24 AM I took the chips out of the sockets and resoldered each of the LS244 socket pins - but it still shows the Geneve ROMpage instead of the RS232 and PIO Quote Link to comment Share on other sites More sharing options...

Maybe change them with the other 4000 and see if it fixes this one and makes that one behave as this one is? 2 Quote Link to comment Share on other sites More sharing options...
Gary from OPA Posted Tuesday at 04:39 AM Share Posted Tuesday at 04:39 AM would check the 138's and the 259's as they have to do with decoding address space and cru bits, just to be sure. 2 Quote Link to comment Share on other sites More sharing options...
NewcomerTI Posted Tuesday at 01:42 PM Share Posted Tuesday at 01:42 PM I changed out the LS244 chips and got the same results as before. I will check the other chips to determine if one of these is causing the fault. Quote Link to comment Share on other sites More sharing options...

You may find one is bad and have it narrowed to that one. Did you build these recently? I've built three, One over 20 years ago, 2 about 2 years ago.

NewcomerTI Posted Tuesday at 02:59 PM Share Posted Tuesday at 02:59 PM The one board I bought populated. This one is a bare board project and I’ve built it over the past 6 months - ran into this snag on the configuration as it still won’t just behave in either of my systems.

NewcomerTI Posted Tuesday at 03:01 PM Share Posted Tuesday at 03:01 PM I’ll start changing out IC’s to see if there is an offending chip giving the board angst. Quote Link to comment Share on other sites More sharing options...
