I’ve newly acquired a Turbo 040, can someone tell me what the 4.11 ROM provides over the 4.01 ROM? Are there known issues or benefits to running the different versions?I just stumbled across this thread - but I thought I'd mention that I recently upgraded the ROM in my Turbo 040. I've got a few PLCC32 rom chips left (they came in a pack of 5), and I have a programmer - so if anybody needs a 4.11 ROM I'd be happy to send you one.

I know this is an old thread, but I was wondering if this ROM tweak might help an Interware Booster CV40-40 work in an SE30? I recently found one, and it's for the Color Classic II, but with a PDS tweak, it could be plugged in to Bolle's riser or a TwinSpark.Good news. I've just programmed the patched ROM to my ROM-inator II MEGA and I can now boot my SE/30 with my 40MHz Turbo040 (ROM v.4.11)! Yipee! Thank you for the patched ROM, @dougg3!
The patched ROM boots from my internal HDD with System 7.1 just fine, even without the Turbo040 installed.
Now for the BAD NEWS...
My FloppyEMU from @bigmessowires will no longer boot in HD20 Mode (System 6.0.8), even if I disconnect, boot from my internal HDD, disable 32-bit addressing and restart. I get a skull and crossbones, and then it will eventually boot from my HDD. If I shutdown, disconnect power to my HDD, then restart with the FloppyEMU connected (HD20 mode), I get the skull and crossbones repeatedly. :-(
If I shutdown and remove the Turbo040 and leave the FloppyEMU connected and power-on, System 6.0.8 boots perfectly.
Thoughts?
Pretty sure the LC PDS is not compatible with the SE/30 (IIci) flavour. Found this online :I recently found one, and it's for the Color Classic II, but with a PDS tweak, it could be plugged in to Bolle's riser or a TwinSpark.
