Retina Z2 RTG 4MB Graphics Adapter

Hello my fellow AmiBayer's

Today for your purchasing pleasure I have a Retina Z2 4MB Graphics card


I have been reducing my Amiga Hoard as such I have two of these that I no longer have a use for, I have promised a friend one of them - as such here is the other one for you =D

what can it do?

Retina Z2 4MB RTG graphics card -

• NCR 77C22E+
  
  • 90 MHz max pixel clock
  • 70 MHz in 8 bit modes
  • 25 MHz in 24 bit modes
  • 15-75 kHz horizontal frequency
  • 50-100 Hz vertical frequency

Whats Included?

Other than what you see here, the graphics adapter comes with the original manual and the following driver disks

Retina 1.4 Drivers
EGS drivers
AGA suppliment Drivers

you can also download these disks form here


The Ugly Duckling

Its a shame that the Retina Z2 gets shunned as there is no Picasso96 drivers for it (P96 doesn't support segmented memory), but I have found Retina/EGS drivers perfectly fine and you can use mode promotion tools for custom screens (the same as under P96)

I will say that setting up the Retina Z2 is a little harder to setup compared to P96 compliant device, as you have to setup a Monitor Definition first, (this is explained in the manual) however this is no harder than setting up CGX 3 or higher to be honest.

Some programs (like "Imagine Ray-tracing" program have direct support for this card)

I have also read that on amiga.org that there is a CGX driver for this card, some where out in the wild...


Is this card for you?

Its a classic (cheap) adapter and would suit an A2000 or A1200 with a Zorro 2 Bus, it will give you an RTG card that is suited for desktop applications and (chunky data) based games (like DooM).


A hill of beans

Not looking for much - this little bit of history can be yours for the princely sum of £35 + pnp

Possibly interested, just checking something :)

Question:

Is there a pass-through option with this card, or do I need a monitor switcher?

@UberFreak

for WHDLoad stuff you will need a monitor switcher for the Native Video of the Amiga, most other stuff that doesn't support screen selection can be promoted to the RTG graphics card through the use of "NewMode" from aminet =D

hope that helps.

He can also use "ModePro" which is newer, I don't know if it's better though.

2nd in line please, in-case UberFreak suffers some sort of brain mal-function and thinks it's not worth a crazy £35. :lol:

He can also use a Monitor (supporting Amiga Hz-idge) with dual inputs.
Ideally, Z2 into on VGA & the other from a FF/SD. :thumbsup:

Despite some of the downsides to this card, at that money, it's a flipping bargin. :nod:

It's a pretty reasonable RTG card. I have the 2MB version, graciously sold to me on here by Tajmaster. Anyone know how easy it is to find more RAM for it? Might be worth upgrading it to the full 4MB if I can.

This is a ZORRO II card. I had a 4Mb one in my A4KD back in 1992. When I upgraded to the ZORRO III version, it was a totally different experience.

Check those links for the support. CGX4 r0x0rz. :nod:

RE the Ram, it's those oh-so elusive ZIP chips you need for the upgrade. :thumbsup:

@ Keith

Not dissing your thread Keith, just extrapolating a little. As I said above, it's a bargin. :nod:
