Re: Frontier Elite poor frame rate - booster required!

This is Amiga related: 50MHz 68000 booster developed by friend of mine, running Elite Frontier: Homepage: http://amigaprj.blogspot.com/2015/09/hc508-amiga-500-68000-50-mhz.html btw it has fastram , fastrom, IDE, CF...

Re: Frontier Elite poor frame rate - booster required!

Hmm, am I wrong in thinking the cache is actually part of the CPU? But then maybe not, since it's still a 68000 in that case, I'm not sure where the cache is on the Mega STe, I always thought it was just CPU cache. I do know there were always random things I had to disable cache on, or clock down t...

Re: Frontier Elite poor frame rate - booster required!

AIf I remember correctly, Frontier also benefits from a math copro.

I doubt fast rom and a simple booster will do much to improve the framerate, you need an accelerator with cache.

Re: New TT + FALCON/ST PC-like case.

Not wanting to be the one to throw a wrench into a project... The TT/MSTE got similar dimensions and could probably share a case. But the ST/STE/F030 have different dimensions and should probably be considered a project of it's own. Ofcourse, for any case to be really interesting, a well thought out...

Re: MegaSTE: Details of implementation of clock switching and cache?

Afaik there is no such documentation. However, every build I have seen of these maintain two state machines in logic, one simulating a 8MHz CPU towards the bus, and one simulating a xxMHz bus towards the CPU. So yes, waitstates are inserted as needed. (at 16MHz it's pretty easy to do, it get's more ...

In short, no, the incompatibilities that exist are much smaller (setup time for blitter, autovector interrupt cycles etc).

Re: Mega STe differences ?

But I was wondering how you can turn On the Blitter ? (as it seems you can turn it off in the General CPX ?!) Technically you can't really turn the blitter off, just tell TOS (or whatever program that respects the setting) to not use it. Is your Mega STE by any chance equipped with a HD floppy? Are...

While the FPGA clones certainly got the potential to have the ST/STE replicated 100% hardwarewise, they are not there yet. There is still work to be done on the custom IC's.

Well, isn't AdSpeed affected with compatibility problems with IDE? Theoretically it is.

The HBS640 T36 is the fastest option if you can locate one. An ST version of the wicher is certainly possible, I suspect that's where Exxos want to go, with fastram a lot of the drawbacks of lacking cache is mitigated, but no, the amiga version wont work with atari. I'm assuming you mean fastest of...

Re: Recommended accelerator options for ST

Looks like STE has the better speed boost available (32MHz vs 16MHz for the STFM and Mega ST) - do you know the reason for that? I’m also guessing that these are just faster clocked 68000s rather than a CPU upgrade like the 68030? With this being the case, is something like https://retro.7-bit.pl/?...
