ZuluSCSI Pico Slim works fine, ZuluSCSI Blaster does not
Posted by: KI5NYZ on 2025-06-10 18:24:58
Have a ZuluSCSI Pico Slim with SCSI/Link. Both booting/using and wifi work great in my SE/30.

Installed a ZuluSCSI Blaster with wifi module.

Powering the Blaster via USB, internally via termination power, or internally via the berg connector plugged into the analog board does not work. The LED on the Blaster lights and flickers during boot, System 7.5.3 boots but locks up while populating the desktop with icons. The log on the SD card says the RM2 (wifi module) is not detected although it is socketed in. The LED on the RM2 never lights up. I measured 3.3v on both RM2 v+ pins to ground pins of the RM2 header.

I am using the same SD card and emulated HD01.hda and NE6.img files and moving the card between both ZuluSCSIs.

The only dip switch enabled is the termination. The se/30 was recently reloaded with a v5 repro board from Caymac, the analog board is recapped, and the psu is a BabyFace model. Both ZuluSCSI are running last weeks firmware build. Verified internal SCSI still works by removing the Blaster and reinstalling the OEM HDD.

128MB of Caymac Blink RAM, Caymac RTC, Garretts ROM SIMM in System 7 mode, and ZigZagJoe's 2.0 Booster. SD has HD1.hda with System 7.5.3, HD2.hda with games and apps, and NE6.img for the WiFi.

@KI5NYZ are you able to fully boot without the RM2 module installed? You say "System 7.5.3 boots but locks up while populating the desktop with icons" but are you able to fully boot when the RM2 module is not physically present?

Which model of machine are you booting when it doesn't work? Is it the SE/30 or another machine? If it's another machine, what's the model of this machine?

Also, it would be great if we could continue our e-mail thread regarding this matter, as the 68kMLA isn't really the most appropriate venue for this particular discussion.

My apologies. I responded with the requested images last week, and again yesterday once I received and tested with the molex->berg cable.
Will try tomorrow to see if it boots properly without the RM2 fitted.

For anyone who comes across this thread in the future, this ended up being an assembly issue, which was fixed by sending a replacement RM2 module to @KI5NYZ

Yes, thanks for the support. It works great.
