Viper accelerator identification

Delbhoy79 · 09 October 2015, 22:01

Bought an A1200 that arrived today only to find this little beauty in the trapdoor. Anyone know what model it is exactly? All I know is it has 4mb on it. Thanks.

Yes I've taken the battery off now 😉

Looks like THIS one to me.

No problem. Good find, bet you're well pleased.

What a nice surprise! I have one of those, no complaints except it is a bit glitchy on some WHDload demos. It will take 128MB RAM with a firmware upgrade. There is also a "ferret" SCSI board for it but probably not worth having even if you could find one.

Delbhoy79 · 09 October 2015, 22:38

Ha this is pleasing me

Ive got an aca1221. Would you say this is better than the aca?

Arnie · 09 October 2015, 22:40

I have an ACA1221 myself, don't think I would swap it for the viper though.

Why don't you use Sysinfo and post or tell results?

Yeah will do. I'll post results of anyone's interested.

Is there an editable database of known Amiga hardware somewhere?
The Amiga hardware book is huge but I am not sure it can easily be added to.

Arnie · 10 October 2015, 15:55

Is there a Wiki entry for Amiga Hardware?

Delbhoy79 · 10 October 2015, 19:52

SysInfo for ACA1221:

SysInfo for Viper 1230:

Retrofan · 10 October 2015, 19:54

Yes, the Viper is better. Not bad for the ACA though. And both are technically declared as "Cowabunga"

Needs more than 4mb or ram though. Some games don't play anywhere near as well as the ACA1221 does.

Daedalus · 12 October 2015, 11:08

More RAM might not help make a game play better, unless you're using it to preload the game with WHDLoad. More likely is that the ACA has better chip RAM timing which can be a significant advantage for games, almost all of which are written to use chip RAM and custom chips specifically.

Leffmann · 12 October 2015, 12:47

When it comes to games on classic Amigas you will rarely benefit from having an ACA or one of the other better and faster accelerators, as almost all games were made for and ran optimally on the unexpanded machines.

But if you want to play the 3D games then for most of them there's no limit really, the faster the machine the better.

Why? That is not the leaking kind.

ElectroBlaster · 22 October 2015, 12:29

I used to own one of these

You have the option of adding an SCSI card but they are like Unicorn poo.
I gave up trying to obtain one!

Had no problems with the card working, plug in and play basically

I put 16mb of ram in it which I got from an old laptop. It ran games a lot better. Some games wouldn't load either. Sold it on eBay for £130 so not bad for a freebie! I'm happy with my ACA1221, 28mhz and 65mb ram.

The ACA is a 020 vs the 030 of the Viper. The Viper has an FPU, MMU and bigger caches. The latter two are probably the cause for some WHDLoad games not working correctly. Turning off the caches of the 030 and/or setting the right MMU settings for WHDLoad should probably fix it for the games which need that.

But i'm a bit late with my response :-P
