WANTED G-Rex a4000T and a4000D

Although if the hardware design is out there could make for a good crowd sourcing project.

Apparently that was tried already.

Disappointing.  Always was my understanding that the G-Rex was the crème de la crème of Amiga busboards.  Would be nice to have some new hardware, either way.

The G-Rex bypasses the limitation of the Zorro 3 bus speed (actually the Buster 11 speed) of around 13 MB/s.  This Z3 slow access is why OS4.1 Classic will not use RAM boards on the Z3 bus (too slow) but will only use RAM on the Cyberstorm board.  A true PCI (version 1) bus supports 133 MB/s transfer speed and while the G-Rex only achieves 50 MB/s, this is quite a bit more than the Mediator utilizing the Zorro 3 bus.

Thus the G-Rex is more akin to the .44 Magnum hand gun than a .22 short round Midnight Special from Elbox :lol:; the former will blow your head "clean off," while the other is good for snakes and varmints...

Well then!

Thats a shame, as most projects would get a good boost using something like Kickstarter but a lot of developers don't like the idea of Kickstarter.

Can't buy a G-Rex = .00, still able to buy a mediator .22, plus you need a  CyberStorm PPC or Blizzard PPC that are a certain version. Double wammy ;-)

:roflmao: If you talk to the right guys, you will find out, that this is not the reason for blocking Z3 RAM in OS4.1...... the reason is to avoid emulation, to force people to buy NG-Hardware.... because they finance hyperion and are not interested in giving other Users the chance to use 4.x without buying the Harware....

I know that it is working! And fast enough for classic Hardware.... And for example NetBSD can use it as normal ram... I tried it.....

[danbeaver]

No, I have run the numbers (see Hyperion classic forum) and Z3 ram along with PCI video ram, is three (3) times slower than CSPPC ram.

You can have all the conspiracy theories you want, but that doesn't make them true.
