A question: (or questions) :D

these are the system requirements:

  • System requirements:      68020, 4MB fast RAM, max. 6MB fast RAM in ZorroII address space,      Kickstart 3.1, HDD
  • Recommended system configuration:      68030@25Mhz with 8MB fast RAM, Kickstart 3.1, HDD


My amiga 500 specs:
CPU 030 @ 50mhz - CHECK
Kickstart - 2.04 - FAIL
Fastram - 32MB outside Zorro II space - ?
Fastram in Zorro II space = 0
HDD - CHECK

And, I got the trumpcard. it provides two Zorro II slots. half length.
one slot is occupied for the trumpcard. and one is available.

Will this GFX card work in my system?
Or do i need to upgrade kickstart and add Zorro II ram?

It seems likely, though the question is *NOT* how much RAM you have in the Zorro-II space, but how much of the Zorro-II space in total is occupied. I do not know anything about the trumpcard, so I cannot really answer.
Only the trumpcard itself occupy the ZII space. By how much, i have no clue.
The fast ram on the derringer is outside zorro space.

The card itself occupies 2MB (plus IO space) in the Zorro-II space. In total, the Zorro-II allows for 8MB autoconfig space, i.e. you must have at least 2MB free.
Then it should coexist with the trumpcard, or any other disk controller for that matter.

However, I wonder how the overall construction of this on an Amiga 500 would look like. It is physically not exactly "pretty". The card is for an A2000, so it does not fit into the A500 physically. I believe the trumpcard is something external?
The trumpcard is simply just a Zorro II SCSI controller. and was made for the A2000. But on A500 it comes with a sidecar and the hdd is mounted inside the "roof" of the case. It also includes an edge connector that provides the A500 with (in my case) two zorro slots. There was made an optional ram board for the trumpcard A500 version.

No. The RAM and the CPU is required to run P96, not for the card itself.
Hmm... in theory, it should work in my setup then....
I need to start saving some cash.
