Probably you all already know, but there is an Atari spec for the Sparrow incl. registers.

Re: Recommended accelerator options for ST

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. A while back someone discovered old schematics of some of the IC's, and I'm sure these findings eventually will find it's way ...

Re: Recommended accelerator options for ST

Well, isn't AdSpeed affected with compatibility problems with IDE? Theoretically it is. I've got to see the combination in action before I can tell if it is a problem, or just an annoying effect of IDE access constantly changing the AdSpeed's speed setting. Exactly! I prefer Stefan Nitschke's boost...

Re: Recommended accelerator options for ST

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/?...

Re: Recommended accelerator options for ST

Well, the best accelerators for ST/STE are the old classic ones, with cache. Like ICD's AdSpeed and the Mega STE.

Without cache, memory access is not improved at all, which basically is like replacing your car engine with a faster one, while locking your gearbox down to three gears.

Re: Possible to choose which FPU?

No, it's not possible. The reason is that the CPU/FPU combo with 020/030 and 6888x is essentially a single CPU to the system, just as the 68060. Since these are not designed to work in tandem, or in a multiprocessor system, only one can run at any given time, and they have no means to access eachoth...

Re: Wanted: 520 STM PAL

I love the old 520ST model, and I have a couple. In many ways it's my favourite model. They are often found fairly cheap over here, going for $50 or even less without drive.

Re: Reset button not working on STF

The reset button on the Atari is, tbh, a very crude construction. From your desription I'd say oxidization s the culprit. How has it been stored?
