Time to say goodbye.

In case its of interest here is a debugged + improved
version of the above soundwave program:

http://www.whoosh777.pwp.blueyonder.co.uk/tone.c

it plays a smoother sound wave for 2 seconds,
a pleasant tone sound,

here is the binary:

http://www.whoosh777.pwp.blueyonder.co.uk/tone

just 2k, if you have a classic Amiga
then run it

tone

and tone will occur for 2 seconds through channel 0, you can try other
periods + volumes thus:

tone period volume

period + volume are complicated to understand,
but 64 is maximum volume == 0 decibels,

period relates to the frequency, 130 is the
current default value

Anyway OS-emulation is not enough to run such a program,
you would need at least s/w emulation of the custom chips,

I am not sure how s/w emulation would cope with a more complex
version of this prog that had one channel modulating frequency + amplitude
of another.

According to the RKM each audio channel is allocated one DMA slot
per horizontal scan line of the video beam, this is going to
be tricky to emulate accurately in s/w, note that many classic games use tricky
timing eg with floppy drives as a piracy prevention measure.

You could emulate the custom h/w to some extent but I think it
will always lack the precise timing and synchronisation of a true
Amiga.

for these reasons I believe someone must incorporate the custom h/w
or a clone thereof in future Amigas then OS3.9 could be done merely
by using a 68030 emulator, ie emulation of CPU only.

But because Eyetech refuse point blank to bring the custom chips
(probably because Gateway have raided the IP), Hyperion have
got their work cut out. Were Eyetech to do the custom chips the
A1 + OS3.9 could easily be out in maybe 3 months it would really
turn the A1 project into a non-issue, however without the custom chips and
its a major issue.

You can emulate the ChipSet's registers no problem. You can set up these virtual registers that will emulate the Chipset functions.

But you won't get the timing right. The Whole Emulation would be out of sync. The reason why UAE is slow is because it has to keep the chipset timing in prefect sync with the CPU... take away the Chipset emualtion and you get Amithlon (MorphOS and AOS4) 68k emulation speeds.

You can't design a custon Gaphics chipset anymore... The whole Amiga 1000 was brought in for around $35 Million... that's how much one chip from Nvidia or ATI cost to develop (probably more given inflation)...
A custom sound chip isn't needed as a good DPS will do the job...

Basicly Custom hardware is a dead end (if you needed use UAE), and custom hardware is only any good if you have a massive budget (bigger than Nvidia) and a good return...

Frankly, Neither Eyetech nor Genesi could afford to have custom hardware.... and Neither Hyperion nor MorphOS want to be bogged down with Custom chip emualtion.

AROS does plan to have a highly integrated emualtor for games, but you need to talk to "The Emulator Guy" about that.

But because Eyetech refuse point blank to bring the custom chips
(probably because Gateway have raided the IP),

Heh.  What a vivid imagination you've got there...check out the Google archives of Dave Haynie posting in csam (you know who Haynie is, right?) and take a gander at his words on reproducing the custom chips.

Also, despite what some people think, NTSC or PAL timing-locked raster interrupts do not a great chipset make.  Once upon a time, maybe.  

Live with emulation, or buy yourself a pallet load of A500's and A1200s (unexpanded, of course...just about the only rigs that'll run that nasty hardware beating junk).

Hi,

@Jaruzel,


OK go ahead and quit, just pack up the old Amiga, throw
it in a closet and go on with your life in the PC world.

I have 6 PC's and 6 Amiga's, I still use the Amiga for a
lot of stuff. You won't see me giving up on the Amiga

So what if it is by PC standards slow, you know only 25
through 60 mhz. I have a 2.2 gig hurt PC that the Amiga
beats in on time everyday. Think about it, What the PC
clone heads throw away fit very nicely in the old Amiga.

The hard drives and the CDROM's that they are getting rid
of because they are to old and slow run nicely in the Amiga.

Don't give up just because some PC clone head says that
computer is antique, would you throw away a 1961 Lotus Elite,
a 1961 Ferrari, A 1960 Triumph Spitfire, A 1948 VW, heck no,
you would cherish driving it and remember the good old days and
you would probably stay with and chat with the people who drive
these old cars. Same way with computers, they may be old and slow
but they still drive the same as when they were new.

Now that I said that I think I will go fire up my VIC 20 or my
C64 or maybe my old trs-80, hmmmm haven't used that old
C128 lately been too busy playing that old clown game
with the bust the balloons.

Eyetech is a shop selling a PPC motherboard designed and manufactured in the far east.  They have about as much say on the chips that go into the A1 as your local Comet or Currys have on the chips that go into Sony's TVs.

been too busy playing that old clown game
with the bust the balloons.

People still play Kickman??? I hated that game!
It was one of my first cartridge games on the
C64 (before I had a floppy) and I couldn't
stand it, probably becasue my parents bought
me it instead of Jungle Hunt, LOL.

No not when you can banger race them .
