RickyDean Posted April 12 Share Posted April 12 I'll personally be using the DC converters that @matthew180 decribed in another thread. I bought some, but haven't incorporated them into anything as of yet, but eventually all my important cards will sport them. Quote Link to comment Share on other sites More sharing options...
+dhe Posted April 12 Share Posted April 12 Depending on how much space is left in the DSR EPROM it might be possible to add DSK capabilities, but certainly not a minor project. @jedimatt42 has shown all of us, the awesomeness of having everything available in a public github. 1 Quote Link to comment Share on other sites More sharing options...

I did it on my SCSI card just the one for the logic part the other for the SCSI bus does not heat up Je l'ai fait sur ma carte SCSI juste celui de la partie logique l'autre pour le bus SCSI ne chauffe pas Edited April 12 by humeur 3 Quote Link to comment Share on other sites More sharing options...

DC 2 DC converters, want to make sure it runs as cool as possible. 2 Quote Link to comment Share on other sites More sharing options...
Shift838 Posted April 13 Author Share Posted April 13 (edited) I got the prototypes in. I have put one together and the system detects it with no issues. I will be testing SCSI disk functionality over the weekend extensively. Crossing my fingers and toes.. Edited April 13 by Shift838 9 Quote Link to comment Share on other sites More sharing options...

Love the layout and no SMT and the voltage regulator part looks nice, and the dual connections and usb power part. 3 Quote Link to comment Share on other sites More sharing options...
+InsaneMultitasker Posted April 13 Share Posted April 13 56 minutes ago, Shift838 said: I will be testing SCSI disk functionality over the weekend extensively. Woohoo! That looks really nice! FYI, I noticed the EPROM is labeled v1.6. This typically corresponds to the boards with the modifications/daughter board and Device routines from Michael and Haarald in bank 7. Version 1.5 is typically the unmodified boards with the non-PDMA routines in bank 7. The source that I have does not contain both PDMA and non-PDMA routines in bank 7, so if things don't work as expected, consider testing the V1.5 EPROM. Can't wait to see how it turns out! 4 Quote Link to comment Share on other sites More sharing options...
Shift838 Posted April 14 Author Share Posted April 14 Initial testing going well. I have tested the below on the TI-99/4A using the DSR 1.6 and a ZuluSCSI device via 50 pin IDC ribbon cable. The ZuluSCSI is being powered up by the new SCSI card via a USB cable too. Card recognized in TIMODE - Success CRU selection - Success Formatting drives - Success Copying files From TiPi to SCS1, SCS2, etc - Success From SCS1 to SCS2, etc - Success From Floppy to SCSI (need to do) HRD to SCSI (need to do) IDE to SCSI (need to do) Reading and execution of files from the SCSI drives - Success Deleting Files and directories - Success Renaming - Success Protecting/Unprotecting - Success Will test everything twice on each system, once with the 50 pin IDC ribbon cable and the other with the DSUB 25 male to male. Waiting on that to arrive later today. Still have a few things to do as you can see on the TI before I move to the Geneve to test. If anyone can think of anything else for me to test, please shoot me a private message. 9 Quote Link to comment Share on other sites More sharing options...
Shift838 Posted April 15 Author Share Posted April 15 I got the 25pin DSUB female to female cable in yesterday evening. Wanted to go ahead and test it as I was wondering if I got my wiring right on the connector. Well, yes and no. So, it would not work via the DB25 connector at all. checked my schematic and all is good, figured it was the cable that it was not truly a straight through cable. Well, it was, needless to say I was perplexed for a few minutes. I always do something before I send my boards off to be tooled, but this time I did not on the DB25 connector. I got the library from mouser, and I have never had this happen with mouser. So, this is a first time for them. Well needless to say, whoever designed their library for the DB25 PCB connector got it wrong! They actually mirrored it, so the footprint is actually for a DB25 male although the part is female! So, everything is exactly opposite of what i need it to be. Good thing for prototype testing! lesson learned, will always check no matter what now.. Now I have a female to male DB25 cable coming in tomorrow. Thought I had a DB25 male to male gender changer that would change the pinout to a female, but nope, it's a 50 pin. I will continue my testing for other aspects though. Thanks mouser! 2 Quote Link to comment Share on other sites More sharing options...

Like the IDE card I'd like one bare board of each, prototype and production. 1 Quote Link to comment Share on other sites More sharing options...

My last run of the IDE through hole design I sold bare boards and almost 1/2 of them came back for me to fix because something was done wrong, and the users could not figure it out. So, I have yet to decide if I will be offering bare boards or even kits. I'm honestly leaning toward a complete tested board only delivered. 1 Quote Link to comment Share on other sites More sharing options...

Shift838 Posted April 17 Author Share Posted April 17 received the new DB 25 male to DB 25 female straight through cable to test to make sure the pinout was backwards from mouser's library and it was. that cable works great with the card. I have corrected the footprint for the final board run. 4 Quote Link to comment Share on other sites More sharing options...
Shift838 Posted April 19 Author Share Posted April 19 (edited) I have been able to test the below finally. Boot from SCSI via Geneve with MDOS 7.42 File copies: TIPI to SCSI SCSI to TIPI Floppy to SCSI SCSI to floppy IDE to SCSI SCSI to IDE HRD to SCSI SCSI to HRD HFDC MFM to SCSI SCSI to HFDC MFM Execution of files from both TI and Geneve Rename, Delete of files both TI and Geneve Create and Delete of folders on TI and Geneve Will do more testing through the weekend to put it through its paces. But looking good! Edited April 20 by Shift838 5 Quote Link to comment Share on other sites More sharing options...

+9640News Posted April 20 Share Posted April 20 @Shift838 Did you resolve the issue of executing AUTOEXEC on bootup with the Geneve? This may be answered in another area already as I am checking out all of the posts after not being on for ab out 3 days. 1 Quote Link to comment Share on other sites More sharing options...

When I changed the default location with CYA, everything started working.. 3 Quote Link to comment Share on other sites More sharing options...
+dhe Posted April 21 Share Posted April 21 @InsaneMultitasker - shouldn't the default be, try to load autoexec from the same place system-sys just got done loading from? Quote Link to comment Share on other sites More sharing options...

Yes. If CYA is required, then either the LOAD-SCS loader is an earlier revision and/or the current loader needs to be updated to set the proper device flag for the OS. I recently mentioned this elsewhere, though it might have been lost in the back-and-forth. 2 Quote Link to comment Share on other sites More sharing options...
+InsaneMultitasker Posted May 1 Share Posted May 1 I reached out to Harald and asked him about releasing the source code to bank 7 for the updated PDMA cards. He has graciously posted the files to the SNUG site for interested. If you see a matrix of numbers, click the yellow highlighted one. https://s-n-u-g.de/ascsi/index_en.php 3 3 Quote Link to comment Share on other sites More sharing options...
Brufnus Posted September 7 Share Posted September 7 On 4/8/2024 at 5:46 AM, Shift838 said: I have been working on an updated version of the WHT SCSI REV F card with permission from Richard. I have corrected (i hope) a couple of trace issues that were on the original version. I have also removed some unused circuitry. I have replaced one of the 50 pin IDC header connectors with a 25 pin DSub connector, much like the ASCSI card has. I have also replaced the original 4 pin power connector with a USB on the back so one can power a USB type SCSI device like the ZuluSCSI. prototype boards are currently being made. This is just one of the cards I am currently working on. Another is in the works, but won't let the cat out of the bag just yet. Here is a render so your mouth can water. I'm interested in buying one of these!! Quote Link to comment Share on other sites More sharing options...
