ATonce Plus
10 messages in this thread
I have the ATonce Plus installed in my A500 computer. It looks like it will
do what I want but I would like to use the serial port. Does anyone know of
any communications programs that will work.
I've also run across a few programs that seem to have a timing problem with
the sound. They don't exactly lock up, but a sound that usually takes only
a fraction of a second to play seems to strech out forever.
Update: I got my communications program working by going in and changing
all the OUT 61,AL instructions to NOP's. Does anyone know if there is a
correction to the AT-once plus software for this problem? Does anyone else
have any other ways of correcting for this? Is anyone out there???
Hi! I've been having the some problems with my Atonce+! I haven't found
anything to fix the sound problem, other than disabling it in each program.
On the communications, most of my comm packages don't work, but I have a
couple that do, one commercial one that came with my modem, even implements
up to MNP-7 in software!
It's been a LONG time since I dabbled in 80X86 assembly, so could you
refresh my memory on the OUT 61,AL instruction.
Amazing Computing said that the version of software for their review was
2.34, I have V2.33, so maybe the next version fixes some of the problems, I
suppose it's time to write Vortex again!

I wrote a basic program that searched for every OUT AL,61h instruction and
replaced it with two NOP instructions. If I remember correctly, OUT 61,AL
was decimal 230,97. NOP is I think decimal 90. I'll have to go back and
look it up again.
I went back and looked it up – NOP is hex 90. I wrote a program and
uploaded it into library 12 here. NSOUND.COM – self extracting archive.
Includes source and documentation. <btw> it's OUT 61h,AL, not OUT AL,61h.
I got it mixed up. I hope this helps.
p.s. Have you got any info on when/if Vortex will have the software update
for EGA or VGA 16 color ?
Unfortunately no word on VGA or EGA color, though with only 16 colors, I'm
not sure it would be worth it — to slow, and not enough colors.
I'll check out your program when it shows up!
Another problem Iv'e been having with the ATonce+, is that it cannot talk
to my DataFlyer RAM card, it can only use the RAM from my ADRam 540, any
suggestions??

I don't know. I have the A590 w/2MB RAM and it sees all that. It seems
like they ought to be able to come up with a fast emulation of VGA 16
colors. The Amiga has no trouble with 4 bit planes, and they could create
a custom display list so the video memory had the same arrangement. The 16
color text is slower because the Amiga doesn't have a 'character' mode.
It's all graphics.
Do you have to run a program on the Amiga side before the RAM in the
DataFlyer is recognized, or does it autoconfigure?
My wish list: VGA 256 color using DCTV.
The DataFlyer RAM card is true autoconfigure… The ATonce sees it, but
when it tries to use it — GURU, or at best a scrambled screen. None of my
external RAM is seen if I use AmigaDOS 2.0.
It's true the Amiga has no problems with 4 bit planes, but with the '286
taking clock cycles from the processor it'll never be as speedy as the
native stuff, plus it's hard to write video conversion stuff… Though I'm
sure they could speed it up over what it is now! Any more than 2 bit
planes is just to slow for me. (I wonder how they programmed the video
conversion, and in what language they programmed it in. If it's the same
language as the INSTALL program, no wonder its slow! (compiled BASIC…

I suppose you've tested the RAM and it is all ok. I guess when I upgrade
to AmigaDOS 2.04, I may need to get a ROM switcher.
Yep, I've tested the RAM, and I would suggest you get a ROM switcher and
V2.04 (2.04 is Much nicer)
If you get a ROM switcher, I'd suggest the Multistart II rev 6a version (no
matter what version of motherboard you have!) This thing was just made for
something like the ATOnce — not fit problems!
