Re: TF536 - Freeze on Disk (write) access?

I might have run into the same or similar issue: transferring files via AExplorer from the PC to an A500 (with TF536 and buffered IDE) over serial cable (either 38400 or 56700baud). The transfer randomly locks up the machine. Serial should stress IRQs quite well...

Re: Terriblefire State of the Union....

I’m glad the terrible fire is not fully extinguished and there’s still sparks of joy in there for you. Don’t let the actions and words from individuals drag you down, the vast majority of the community supports you. Maybe you can find someone else to carry the baton to the finishing line? I’m still ...

Re: Getting software to work on 68LC060

FYI The only reason any Doom port would need an FPU is because it lacks the 030’s 32x32->64bit integer multiplication and the author is instead using the FPU to perform this in floating point and convert back to fixed point right after. I can probably produce an 060 optimized version that is not usi...

Re: Source of 68030 with MMU?

https://www.nxp.com/docs/en/product-change-notice/PCNR00283.html https://www.nxp.com/docs/en/product-change-notice/PCNR00321.html I think at some point they just consolidated manufacturing of all 030 chips to 0.8um, yet still sold them at different price points. Could also be due to testing - its a ...

Re: Source of 68030 with MMU?

If we believe this info http://www.cpu-world.com/CPUs/68030/Mot ... RC50C.html

Then those chips labeled RP25C are using a mask (0G40W) used for 50Mhz MC68030RC50C chips

Re: Software options to test load capabilities of a 030 CPU on TF536

Battle Chess gets the CPU quite toasty. To stress the CPU you’ll want to use software that interacts with the chipset very little, so the TF has little time to step down to 7MHz.
I guess, using Lha on many big files would be a good test, too, to stress CPU and IDE.
