It doesn't seem like he has posted the fastchip nor OSN ROMs. When I created my thread for this, OSN comes in 2 ROMs and the fastchip you can't just dump and burn to another ROM, it doesn't work.
Agree with opinion of mechanerd's offering in post #14,
the only one that looks good is
Which has me as the source. It should be called Omnimon4k
since we now seem to have Omniview4k thanks to mechanerd
in another post linked to in post #11 and there his
ROM reading ATR seems to have worked. I don't have a
working Atari to know why or test how good it is
and dealing with rom issues while running an emulator
is going to be troublesome due the patches they use
etc., skewing results there. In this post at least, it
seems the ROM reading ATR didn't work so very well.
And I of course have no real clue as to why.
I thought we corrected my misunderstanding of what the
issue was with the math pack in another thread already?
At any rate, I was wrong we don't need a special 2716
to do that with, according to page 3 of the ramrod
instructions we only need a 350ns 2716 to burn the
code onto and bob's our uncle. So it would work just
fine, yet you keep saying it won't and I keep having to
say I was wrong about my assumptions in another thread
long ago when we didn't have good instructions for the
ramrod board which is posted as a link in post #9 here
in this thread.
But I'm no expert, user 1050 here on Atariage was helping me out. I never got further than using my stock math chip with OSN and an Omnirom that didn't work properly
Oh please, no to the Omnirom speak, it gets too confusing
already. We only had Omnimon4k at that time so that
had to be it. If you'll read the third bullet in post #6
Atariage user six can fire off his Omnimon4k by doing
a jump thru 0xC001. It may be that the often invoked
RESET+SELECT method was an addon to XL/XE version of
OmnimonXL/XE and we just didn't ever know that before.
I don't think we have instructions for 4K Omni anything
Would this work? If so, what ROM is the Fastchip ROM and what is the OSN ROM?
- Omniview80 C000-CFFF
- empty/zero D000-D800 (hardware registers)
- Fastchip D800-DFFF
- OSN ROM E000-FFFF
Yes it would work. Fastchip rom is in my burnfile.zip
offering in post #5. OSN V4...? is also in there.
But so far only the Atari file header version of
Omniview4k is posted under a different name in the
programming section linked to in post #11.
So I'll strip the header and rename it correctly
My original offering from way back, renamed
Fastchip by Marslett
And mechanerd's version of OSNE and OSNF combined
from the other thread where it did not have the
fastchip code but instead the standard math pack
code. With headers over there, here it is stripped
of math pack and headers as one OSNEF file version
who knows what? It is a different one yet so you
might give it try.
I've been busy, I think OSNv601 is as ready as it
can be without byte for byte confirmation of
accuracy from anyone holding onto that code. This
was recreated from PDF source only so it may contain
OCR errors not yet corrected - if you find anything
you may PM me or just reply here, your choice but
I certainly want to know about it.
And for those that don't want the hideous green
of OSNv601 here is transplanted US+ color
scheme which is the only hack done to it and
should be quite agreeable in appearance.
OSNv601 does seem to test for which Omni is at
0xC000-0xCFFF and does branches accordingly.
Have no clue if it's done right at all or not
and it may be that this code isn't the actual
released version in the wild - Newell may have
patched the powerup vectors to do things
differently and I have no way to test it at
the moment. Can't sit on this in the meantime
either, simply can't even suggest as to when
I'll sit behind a real working Atari ever
Fast chip was an XL/XE thing that occupied not
only the original math pack area but also
international character set and maybe even
0xCxxx region to some extent as well. Don't
know a whole lot about it, ClausB did some
work on a version of his IIRC, but the original
seems to be untouchable as to source, concept
or anything else.
