Early ST BootROM dumped!

[Factor6]

Hi there.

As I promised, we made the dump of the bootROM chips of my early 520ST+.
It has 16K and no emulator can handle it. Try on yourself.

Cool!

I'd also be interested in a dump of your keyboard ROM too, if you don't mind doing so, as I'd like to see whether it ever changed between the original issue and the Mega STE (which is what I've got).

The attached program will hopefully run on your machine. It was written by me, so its only been used/tested on my machines, but I expect it'll work. Its simple enough, runs from Gem and it will produce a 4kb ROM file after about 20 seconds or so.

If you have time, that'd be great...

Cheers

did you send this to the makers of hatari and/or steem??

[wheeel]

No, not yet: this is its first "publication". As far as I know only Saint emulates a 6301 (although I've never tested how fully it emulates, or whether it just does enough to allow those demos that get the 6301 to run their own code). I was thinking of trying to write some full emulator code for Hatari, but this was only a vague thing at the moment since I don't have the time to devote to it. Feel free to pass it along, if you think it worth while! I can try to did up the sources for it, if necessary, but I wrote it back in 1999 and may be lost in the mists of time!

I remember reading that there were changes to the keyboard firmware at various points: I think the TT had support for a third mouse button for example??? But looking at the schematics for the original Atari ST keyboard, it differs from the later editions, so again must (may) have had different firmware. I have an STE and a MegaSTE and they have identical firmwares. This is why I'd be interested in a ROM dump from factor6's computer. I might then see if I can get hold of a dump also from an STFM and a TT, maybe even a Falcon. If the TT did indeed have support for the third mouse button (which the MegaSTE didn't as far as I can ascertain even though it has the additional signal on the mouse port and incidentally wikipedia says it does...), then I guess there must be some special handling for it in the firmware - at the very least to detect whether it is pressed!

Basically I'm just curious...

its true there is an earilier version of tos , it supports bdos instead(before) they made it gemdos. my first version of cubase only works on this tos,, i think because it don't function under tos 1 or 1.6 2 or more...

I patched it by adding TOS 1.00 header and moving overwritten code at begin to empty area at end. Now Steem and Hatari accept it (so, emulators look TOS header for validating).
Under Steem it loads US floppy based TOS 1.00 (I had only it at hand) and Brataccas, same in Hatari. Most of games will not load, of course.
Don't see much use of all it, but may be good for some testings...

Doesn't work with STeeM 2.6 and says it's an invalid TOS image etc.

I tested it with Steem 3.2 .

OK thanks will give it a go on a later version of STeem and see what happens ta

Any way to reach the patched Version too

A rather current version of Hatari can load TOS 1.00 de, TOS 2.06 de and Emutos 0.9 (floppy edition) from corresponding boot floppies. In all 3 cases, the desktop appears but I didn't test more than a bit of clicking and opening the floppy contents.

*Edit* Both the unpatched version above and the patched version by ppera do this.

This UnPatched Old 2-rom TOS:
http://www.krupkaj.cz/tosload.img
And
This Atari TOS System Disk:
http://www.pangaelinwillow.net/AtariTOS ... 100_us.zip
work together to boot up with Hatari.

Be sure to use the old rom.
Be sure to put the system disk in floppy drive A

It is odd that Hatari needs to do this ?!

It's to set the memory valid variables so that TOS skips the memory checking. If I remember right, that doesn't work with all TOS version and with emulator checking the memory is useless (checking small part of your host RAM using an emulator, is not the best way to check your host RAM)...

…the Link is dead, I have a Set PROM Chips from 1985 and looking for the Boot Image Floppy ?

Steem authors had written code for it, but they thought the ROM started with $6008, not $6006 like here.
That's why the unpatched image was refused. Now it will work (for those who care!)
Maybe there are various versions?
