#IBM/MAC emulations
9 messages in this thread
Hi,
I own an A2000 with a fatter agnus chip, 9 megs of ram, and an 80 M HD. I use a
1084 monitor.
I need to make my amiga IBM compatible. What is the best way to do this?
I have often heard that an Amiga can beat any 386… but I have been unable to
prove so… guess cuz I don't really know how to use my amiga. I also probably
have the oldest versions of anything in this machine. Ok not the oldest.. I've
got 1.3 kickstart.. and everything else is about version 34.
What exactly is involved with getting PC compatibility, and keeping up with the
speed.. like 386 or 486. If after I get a BB, I also have to get a video
board, sounds board, disk controller card, etc..? If so… Isn't it cheaper to
get a mother board and a separate pc?
Is it possible to get 16.8 million colors with an A2000?
Also, about macintosh compatibility… I have seen AMAX II work on a 500 and it
was much quicker than any Mac SE that I have seen. But had a horrible video
flickering… what gets rid of the flickering, I should say, what is the best
video flicker free product.
Please help me out! Nick
Hi again,
I thought I would ask a few more questions.
For PC emulation, can I run windows? Say I were to get the A2386.. how much
memory will be available when in pc mode. Are there alot of programs and games
that don't work with it? Do I have to get a sound card in order to have sound?
Or is my amiga ok for sound? ect.. ok I'm running into my pervious message.
HOpe to hear from someone soon 🙂
Thanks NIck
1. Well, read the messages just in the last few days on the $200.00
Bridgeboard. You can't do better (price wise) than that, although you
will probably want a VGA monitor and a multifuntion card too, if you don't
want to be restricted to CGA. The cards usually contain a VGA card,
various ports, and an IDC interface for a separate IBM HD, although if you
have enough room left on your 80 the bridgeboard will let you set up a
partition just for the IBM. You *will* need a sound card, just like on a
real IBM. I think the A2386 is limited to 4 Megs, but I could be wrong.
It wouldn't be the first time. Upgrades to a 486 with more memory are
available through a third party, though. The compatability is high.
2. Upgrade your machine to the 2.1 operating system. You won't be sorry,
as long as you don't have a lot of old games you are still playing. The
improvements in functionality over 1.3 are just fantastic. I just
finished upgrading a friend's A1000 (with an external, non autobooting HD)
to 2.1 from 1.3, and he is *very* pleased. There are an vast number of
new goodies available for the 2.04 and up operating systems which make
life a LOT easier, not to mention that many features of current programs
REQUIRE 2.04 or better to activate.
3. Not on a stock 2000. There are add on video boards which allow you to
*display* a 16 million color picture, but they are not integrated into the
operating system and do not allow the system to *run* in 16 million color
mode. If THATS what you want, you will have to wait for the Amiga 5000.
Although the 4000 does have a 16.8 million color palete, they cannot
display that many at once. (256 colors in most modes, or the HAM8 256,000
color mode).
4. To get rid of flicker, you need a multisync monitor, such as the CBM
1960, and either a) Microway flicker fixer, b) CBM 2320 board, or c) a
Flicker Free Video board. Both (a) and (b) plug into the video slot, thus
preventing you from using anything else (like a Toaster) that need the
slot. I haven't seen (c), but I have both (a) and (b), and I think (a)
has a little sharper picture. The CBM board is the cheapest of the three,
though, and it does work.
Lots of luck!

Did the A1000 upgrade that you did use the original motherboard? I have
one in a semi-crippled state due to a conflict between a Spirit insider
and an autobooting A500+ GVP hard drive mounted backwards [I had to
disable the clock on the Spirit board to make it all work, but now have to
type in the time each boot]. I thought it wasn't possible to upgrade to
2+ until I read your message.

Well, it's *almost* stock- it has only a "kwikstart" ROM kit installed.
Of course, with a non-autobooting hard drive, I probably had less
compatibility problems than you would. It uses a Supra drive and the
Supra software ("SupraDiskChange") to recognize the drive.

Nick,
just a note to follow up on your question about bridgeboards. if you have 9
megs of autoconfigure memory, you're going to have a problem running a
bridgeboard. it needs 512k of that autoconfig memory itself, so you can't run
it in a full amiga. –sorry, my shift key has quit on me suddenly–

Hi Marion,
What's this about autoconfigure memory, and not being able to run an A2386 on
my A2000? My 80M HD and 8 Megs of ram are on the GVP card, and the other meg is
from the Agnus chip. I don't understand why I won't be able to run the card? Of
course, there must be a way.
Nick
Nick,
The BB requires a block of 512K of autoconfig space for itself. If
your 8 meg of expansion ram is normal 16 bit ram it will be located in the
normal Amiga address space which is the same space the BB needs. Thus, the
most ram you can have and still bring up the BB is 7.5 meg of fast expanded ram
(chip ram doesn't count.) Since your ram expansion card probably won't let you
reduce ram in other than 1 or 2 meg increments, then you will have to remove
ram accordingly. If the GVP card uses 8 1 meg SIMMs, then you probably can get
by removing one SIMM. If it uses 2 meg SIMMs or requires that memory be added
in 2 meg blocks, then you will need to remove 2 meg of fast ram.
Now, if you have an accelerator card with 32 bit ram on it, and the
accelerator can place that ram above the normal Amiga address space, you may be
able to get by with more ram, but only if the GVP accelerator can fool the
Amiga into thinking that the normal address space is available for autoconfig
cards. I don't know if the gvp card does or can do that.
Ditto what Steven said. Your best bet is to contact GVP and ask them. They will
know what your card can do, and they're very knowledgeable about Bridgeboards.
