elemenoh Posted September 26 Report Share Posted September 26 Getting chime then Sad Mac 0000000F / 00000002 whenever connecting an external SCSI2SD to a Mac SE. I've tried the following: - Changed out the ROMs to newer FDHD versions - Connected to external CD-ROM which worked okay - Made sure internal HDD was set to ID0 (since the volumes of the SCSI2SD are on 1,4,5,6. - Disconnected the internal HDD - Checked voltage rails OK This SCSI2SD works fine on many other Macs. Any ideas for what to check next? I'm kind of at a loss since SCSI seems to be working fine with the CD drive. Quote Link to post Share on other sites
aperezbios Posted September 27 Report Share Posted September 27 It could be the 53C80 SCSI controller itself. Is it known to actually work? It's soldered down (not socketed) on the SE, I believe, but you might want to consider trying to replace it, if you don't know that it's functional. Quote Link to post Share on other sites

Trash80toHP_Mini Posted September 27 Report Share Posted September 27 (edited) Is the external version Termination Powered? Have you tried an external power source? edit: which version of SCSI2SD are you using? Can the USB port be used to supply power?

It's termination powered. I haven't tried external power yet, but haven't needed to on any other Mac. I'll give that a try though. 16 hours ago, Trash80toHP_Mini said: which version of SCSI2SD are you using? Can the USB port be used to supply power? I'm using the external 5.5. Yes, it has a port I can connect to try it out. https://store.inertialcomputing.com/product-p/scsi2sd-v5.5-usps-int-1st.htm Quote Link to post Share on other sites
Trash80toHP_Mini Posted September 27 Report Share Posted September 27 Good! My WAG was that your SE has weak termination power for whatever reason. Has it been recapped? Have you got a meter you can use to determine the power output level if the USB power test proves successful? Quote Link to post Share on other sites
elemenoh Posted October 1 Author Report Share Posted October 1 So I tried with an external USB power source and it made no difference. I also tried with a couple other SE MLBs and hit the same issue. So it sounds like it might be some kind of config issue with the SCSI2SD. I might try disabling all but one ID and see what happens. Any other suggestions? Quote Link to post Share on other sites
dochilli Posted October 2 Report Share Posted October 2 (edited) Perhaps you can use this tutorial: http://www.savagetaylor.com/2018/01/05/setting-up-your-vintage-classic-68k-macintosh-using-a-scsi2sd-adapter/ Point 3 shows some configurations for the SCSI2SD. There are also some images with 6.0.8. and 7.5.5. Edited October 2 by dochilli Quote Link to post Share on other sites
cy384 Posted October 2 Report Share Posted October 2 weirdly, scsi2sd can cause a sad mac if there's garbage data on the SD card, so try zeroing it out. Quote Link to post Share on other sites
