Anyone developing ST ROM software? (OS or diagnostics like Chucky with diagrom?)

What other machines do people OS switch on a regularly?
In case of Atari ST/TT/Falcon, we use ROMs with different OSes like: EmuTOS which is still developed, TOS (most popular are: 4.04/2.06/1.04) and MagiC.

It does the same with my 030 Phil. I think they need a heatsink even if running at 33MHz
the same with my Falcon with 50MHz clock, 68030 was very hot and unstable, finally small cooler fan was needed. on 40Mhz 68030 was hot but stable

Thankyou, similar to the 534 as expected.
Is there no way to leverage the fast ram? Or even just use the MMU to put ROM in fastram?
I posted your question in EmuTOS developer list and I got suggestion to try ROMSPEED:

Re: TF534 Sources Published (includes firmware for 520/530 and 534)

I managed to find some time to publish the TF534 sources https://github.com/terriblefire/tf534 This includes all the most up to date firmware code for the TF5xx series to date. Great. Currently TF534 performance of access to ST-RAM is 86% of 68000: https://www.exxoshost.co.uk/forum/viewtopic.php?f=...

The 536 should be ST friendly with the clock switching stuff. How you’d use 64mb of ram on an ST is another question.
sounds really cool

Re: PhilC's TF534 build x 2

IIRC One of the issues with the current TF design is it does not have all the address bus rooted to the PLD to allow TOS to boot up on the TF card.. So right there we already need a redesign of the TF card.. again IIRC, the PLD used on TF's boards hasn't enough IO to do that.. But we may need some ...
