Title: If I add a GVP A4000-HC+8 Series II Rev II,can I still add more Z3 cards ???
Post by: Effy on June 12, 2004, 12:23:52 PM

If I add a GVP A4000-HC+8 Series II Rev II with 8 Mb Ram in my (still) bare A4000, can I then still add for example a CV64/3D 4 Mb that I still have got ready for use ??? I think this GVP card is actually a Zorro2 card, and a Zorro2 card can only handle maximum 8 Mb ... the CV64/3D is a Zorro2/3 card but I don´t know if the A4000 will accept it. I know that if this would be on an A2000 that the gfx card would not be noticed because the 8 Mb limit has been reached and everything above it is useless ...
I also have got a few Vlab´s. How much Zorro2/3 memory do they need ??? Is this GVP card too filled with Ram ???

I am sure the A4K can handle a CV64 gfx card with no modification. I think the memory issue is confusing you. Its actual memory cards that can cause issues esp. on older Amigas more than the A4K.

The 8 MB barrier is the ZII adressspace  ZIII can adress around 4GB. Still you can only add pure ZII cards to a total max of 8MB, but ZII/ZIII cards allocate their memory in ZIII adresspace so they don`t interfere.
But why onearth do you want to add RAM in form of deadslow ZII RAM expansion to an A4000 ? There are dozens of better ways to expand the RAM on such a system.

Lemmink : I know there are more ways to add Ram, but at the moment I am stuck with two (not one as I first thought) A4000´s that don´t seem to accept Fast Ram modules. A FastLane is too expensive, an X-calibur will come in the third A4000, and at the moment there´s only a GVP 040 8 Mb turboboard on Ebay (USA) ... what options are there avaliable then ???
