Also, my memory is hazy, but wouldn't you need to extend/replace the mmu to address the 14mb? I remember something like an extra ram card which involved the replacement of the mmu and using some kludge like a second mmu tacked on to decode everything ...

You might want to try casting the net a bit further.
Post to comp.sys.atari.st as well, and possibly a few other lists to make it known what you're doing. I'm sure there'd be a few buyers.
If it was 16Mb I'd take one, or possibly two depending on final price.

exxos wrote:It is the problem at the moment that people do not even seem to want a 4MB/IDE board. At cost the PCB will cost £15 each, only 8 will be made, 2 I will have to keep her for dev work, which leaves 6. I can't afford to splash out on £100's to be landed which stuff which may not sell for a year.
This is why we took pre-orders of PeST of about 25 cables before they were made, as that was just to break even with production costs. So unless 6 people chip in with the buys of the 6 boards then it won't happen anyway.
another problem is after xmas I am planning to move away, have to find somewhere to live with a good paid job. So depending how long it takes to sort out my stuff and find work etc, in a couple of months I just won't have time to do any work on this project anyway, or indeed much of anything else. Its why I am trying to bring a close to projects I started before the move.. So other than building the prototypes and doind the final testing, its pretty much done really.
exxos wrote:I was just asking if anyone had done this "particular" arrangement before I spend hours developing a PCB for it all. I'm not upating to TOS206, so if it means I have to load HD8 from floppy then thats fine by me!
the ones on your site needs patches, cart ports, ASCI port, TOS 206, GAL's, Im NOT talking about all that stuff and going down that road just for the sake of booting from hard drive. I have a STE with Veloce TOS 206, works fine with my SCSI drive. The STFM is what I am looking at, TOS 104 ONLY!
So now thats all clear, has anyone developed a internal IDE such as listed on joogn's site ? or actually built that one ?

In reality only Mint can benefit from it. But Mint, multitasking on 68000 without PMMU is again not something really useful.

It's true that not all apps will work (apps not using Malloc() for instance, or apps using DMA), but most will. 14Mb on a ST will make MagiC really usable even on a 68000 computer.

OK. Can you give some examples? And please some APPs, because nobody has benefit from fact that some OS can handle RAM above 4MB. Or you meant that may run in multitasking several PRG at once ? ... hmmm - I think that it is not what I meant, but solo application what needs a lot of RAM.
ppera wrote:I did not exclude mulitasking. But was mentioned that it works not well on 68000. Not to mention low speed. Real benefit is that run solo app, at full speed possible on machine, and that it uses RAM more than 4MB.
Point is not in what is possible, but what is useful, what has good ratio usefulnes/price, invested time.
Do we really need multitasking on ST machines? For what? It is just to may say: my machine can do it...
ppera wrote:So, if I get it correct only some desktop publishing SW is what can really benefit...
joska wrote:All apps that allocates memory using Malloc (and that should in theory mean all of them) is able to use memory beyond 4Mb. Not that many *need* more than 4Mb, but if you're using apps like Calamus or Pagestream 4Mb is rather limiting.

ppera wrote:As I remember most of RAM expansion boards for above 4MB were from Germany - not surprising
Maybe to try contacting developers for some documentation, schematics, SW?
Code: Select all

Situation is that there is much, more useful thing to develop.
