BlueSCSI and MegaST2

[tOriman]

Hi,

This can be a problem when you need to check something like HDD and you don't because you don't have any SCSI host...
I am a hardware man and I have 5 Atari machines mostly for testing purposes.

I would bet money it is incompatibility of the BlueSCSI and the Atari SCSI adapter + TOS. BlueSCSI currently doesn't work with Archimedes SCSI.

Very unlikely to be SCSI adapter failure.

Hard drive failure on Atari regularly causes FDD failure, DMA port HDINT and WD1722 INTEQ are XORd before going to MFP. If one goes mad then both are broken.

You could buy the ACSI2STM which is a an alternative to BlueSCSI designed for exclusively for 16-bit Atari and bypass your SCSI adapter.

The BlueSCSI guys are very hands on, raise an issue on their GIT and try and get them as much feedback as you can with logs and maybe use a debug build of the FW. If you can get them the CMD(s) that are not supported/malformed they are quick to incorporate if they can.

Hi,

Sure alexh. Anyway I can support digitalman as I have disks and adapters exactly for Atari :)

I have fastest ACSI-CF disk by PeraPutnik too - 1.9MB/s

How are you powering the blueSCSI mine only worked using a floppy power connector rather than USB powered?

I used both. Same results.

So update...I was able to get my hands on a Quantum ProDrive. Was from an MAC. I was told the drive works.

However, none of the HD utilities I used were able to do anything with it. I'd appears on the bus, see the image. Strange name, looks corrupt or something. It doesn't appear unless I disabled parity on the drive by removing the jumper. I cannot set termination as it uses resistor packs and they are removed.

The good news is that it sees something, and the floppy bus works ok. I can definitely tell it's different because with the BlueSCSI it just boots immediately off the floppy. With this drive attached it waits and then goes to floppy.

Actually...found some resistor packs! I installed them and now ICD sees the drive. Yeah! So it would seem for sure then I have a compatibility issue with the adaptor and BlueSCSI.

Thanks for all your suggestions.

Bus termination .

Nice, solved.

If you can, before you put everything away, provide debug to BlueSCSI project?

Just raise an issue, put down lots of the information here. They will probably ask you to run and get a boot log. That information will help them make their product better for Atari users in the future.

Or have a chat on Discord

If you read their troubleshooting page... there is a lot of emphasis on physical BlueSCSI issues (bad soldering, shorts, etc.) if you can confirm it works in another retro machine that eliminates a lot of questions.
