Re: 68060 based QL system?

What about potential instruction time improvements that could be had with FPGA design For many register-to-register instructions, the Q68 takes just one cycle already, if run from internal RAM. The much larger factor is SDRAM access, i.e. lack of cache. Further improvements could come from newer, h...

Re: 68060 based QL system?

*strokes RiscPC with StrongARM, remembers working on it.* Aha! That explains everything for me. ;) Thanks for explaining what an RTOS is. :D If SMSQ/E was running on a 2GHz processor, with time slices 1/1,000,000th of a second instead of 1/50th of a second, and only very slightly revised job contro...

Re: 68060 based QL system?

If it were undertaken it would be a labor of love for many people over many years. Love for ARM? I would understand that on an Archimedes forum, but not here. Love is about beauty, most of us love the beauty of the 68K architecture and assembler language. It would be a prime RTOS. SMSQ/E is by no m...

Re: 68060 based QL system?

Few things are more unrealistic than porting SMSQ/E to the ARM architecture. So I never even start thinking of it. Good thing AmigaOS guys are more positive :-D (although they do have advantage of bigger usebase) I don't think it has anything to do with "positive", but - Amiga PowerPC por...

Re: New QL-SD driver

[*]WIN2 defaults to QXL.WIN in slot 2, WIN3 defaults to QXL.WIN in slot 3 (if anybody ever had a slot 3 in the history of QL-SD ;) ). Except me and probably Peter, of course The extra connector was meant to be reserved for other potential hardware add-on, not as SD card slot, so I never used it thi...

Re: 68060 based QL system?

Let's not get hung up on just how difficult an ARM port would be - it's off topic and hijacking the intent of the thread. Which seems to be what we'd like to see as future development paths for new hardware from Peter. Not quite. The topic is how people see 68060 QL systems today, in the light of t...

Re: 68060 based QL system?

Well, thank you for putting so much thought into it before sh!tt!ng all over it. I wonder how far Sinclair would have gone if every time he had an idea, the first thing he heard was "that's unrealistic"... Porting SMSQ/E to ARM would be somehow similar to Clive Sinclair porting the Spectr...

Re: 68060 based QL system?

The '060 didn't add much except higher clocks at disproportionately higher prices. I disagree here. The 68060 is significantly faster per clock, consumes much less power, runs at a useful logic voltage. Did you fall out of the wrong side of the bed, land on lego, break your coffee maker then decide...

Dave wrote:What do you think the whole point of Goldfire was? That Coldfire core was a 68060 with multiprocessing logic.

No, it was a single CPU accelerator card based on the MCF5102, essentially a cutdown 68EC040, that never materialized.

Re: 68060 based QL system?

I have agitated for porting to ARM for many years. It wouldn't be trivial, but it would be amazing. Few things are more unrealistic than porting SMSQ/E to the ARM architecture. So I never even start thinking of it. And personally I like the beauty of the 68K architecture and assembler language. Nas...
