Hello NeXT Community:

I think I'm close to having the new version 6 card working but hoping you can help troubleshoot what is causing the eror which repeats over and over , I'm getting as it starts to boot.
NeXT Turbo Color V74 Rom Chip
1) I have a clean install of Openstep 4.2 on an 8Gb MicroSD set up with 4 2gb partitions , this works great for all NeXT Hardware using the earlier version of the scsi sd 5.0 card with 4.6 flash
2) The Config8.xml file attached is what I use 512 , 139 and 4 sectors per track and it works
3) I've set same disk driver parameters for the new version 6 card in confignew.xml
4) Matched the settings in both cards and saved to device
5) Here is my youtube video showing the boot process and errors https://youtu.be/1yKEHTWeG5A


Check the you tube video for errors!

Any help appreciated and I've forwarded this to Mik McMaster as well!
Best Regards Rob Blessin

I'm looking through this for clues :

yes 6.0.13

Cool hopefully this response from Mike will resolve it , I'll update later but this is a faster MicroSD solution for NeXT !

Hi Rob,

The comment from Mike Perka on the youtube video is spot on - it's a
parity error. The config8.xml file has enabled parity checking,
whereas it's turned off in confignew.xml. Turn on the parity option
and see if it makes a difference.

... however, it may not help. All that does is detect errors, not fix them.

A few people have had this problem. It can be resolved easily, but it
involves a soldering iron. Do you have some very basic soldering
experience ? All that's needed is a capacitor between the "5V" and
"GND" pins of header P404. (Capacitor value between 100uF to 1000uF,
and 10V or higher. The exact value isn't important. eg.
http://www.digikey.com/product-detail/en/kemet/A750EK227M1CAAE016/399-13664-ND/6196322)

The next batch of boards has resolved this problem, and I should have
them next week. I can arrange to swap your board for one which already
has the capacitor on it if you're unable to solder it.

Regards,
Michael.

Hello NeXT Community: Legend in my own mind , so the key is to have a molex 4 pin connector to floppy ide power connector and it works before I had it powering from the scsi cable which works on the version 5 card the version 6 card draws more power so a power cable and connector is needed! Boom

https://youtu.be/jsrEDJ8nRoo NeXT now up and running on the new version 6 scsi sd 2 card , thanks for all the help!

Best Regards Rob Blessin

Are there some advanteges against V5 hardware? AFAIK the NeXT doesn't support synchronous transfers.

see http://www.codesrc.com/mediawiki/index.php?title=SCSI2SD

I think, there are some:

Full-Size SD slot. This makes it much easier to develop faceplates for external access.

Better performance. The hardware supports synchronous transfers at 10MB/s.

Access to the data via USB. The SCSI2SD drives will appear when connected to a PC via USB.

Superior noise resistance to deal with poor termination and poor cabling.

Integrated terminator, now enabled via software configuration

Plus I think that v6 finally stores the configuration ("drives", geometry, ...) on the SD cards which is much more logical to me than storing it on the SCSI2SD device.
