exxos's Atari, Amiga & retro forum

Hey guys,

You may/may not be aware of the BlueSCSI project from the Mac68k forums, I just finished building and testing one and it seems to work on my Atari TT. I haven't tested my Falcon yet, I'll update the thread later with those results.

Update: I am still doing testing, is not working 100% yet as I have had a write error. It might not be the BlueSCSI being the problem though, I think my 5v rail needs adjusting as it's at 4.8v and I probably need to mess around with termination.
Update2: I can successfully copy 6000 files from IDE to BlueSCSI in TOS, but using Kobald causes the stm32 to lock up. Not sure why yet.

900kB/Sec on the Atari TT SCSI port is slow ...

Is maximum 2mb/s?

1400MB/Sec - 1500MB/Sec is the max ...

Atari Falcon has a little bit more speed but not much.

@frank.lukas Okay, well the project is very new and new firmware may change the speeds. I think on a Mac they have measured speeds up to 1.5mb/s.

Yep that is slow, but it may just be early days for the project. What driver are you using? I can see it's HDDRIVER but is it the latest?

I'm now wondering it it would work on the MSTE, though I think that is limited to 1GB drives on SCSI.

@rubber_jonnie on v11.04 right now, I know there's a 11.05 tho. It's only 7gb because I created a 7gb DD image on the SD. You basically just put individual image files on the card and it populates the SCSI IDs with them, really cool and easy to configure.

Sounds cool and a project I need when I get my new workshop sorted :)

I can copy thousands of files in TOS without issue, but if I use Kobald the stm32 locks up after a few hundred files. Anyone know why this might be the case?

Compared to a similar contraption involving the same "blue pill" plugged to ACSI that is said to reach 300kb/sec, it's quite good though.
