A4000D - mainboard reworked by botfixer and boing4000
(rtc-fixed, capacitors replaced and some other stuff)
2MB ChipMem and 16MB FastMem
completed with a batteryholder-replacement by DJBase

CPU - Blizzard 4030 with 68030(Rev.B) & 68882 (both real 50MHz)
(i still own a csppc .. on the paper .. it never returned from repair)

HDD - Maxtor 40GB - 7200 rpm (3MB/s on AmigaIDE)

DVD - LG-DVD with front-usb mod (third deneb-port)

daughterboard - MediatorPCI 4000Di

flickerfixer - IndivisionAGA (pre-series)

graphicscard - Radeon9250 256MB 128bit DVI

vga-output - specialversion from my automatic monitorswitch fitted on the radeon, heatsink from radeon modified to fit in the first slot on top over the mediator bridge
i have 1 slot with pci-bridge, gfx-card and indy-output ... and i take 240MB from the radeon as fastmem ... o3o-Amiga with 256MB ... but hold on :D

soundcard - SoundBlaster128 PCI

network - Netgear PCI (Realtek 8139 10/100Mbit)

USB - Deneb (running in DMA-mode) 2 ports share a panel with the network-card (easy mod) the third port is routed to front of my DVD-drive

memory - ZorRam 256MB ... 030 Power with 2MB ChipMem and 512MB FastMem :nuts :p

and there is still one free slot (for ZorroII/III and/or PCI)

Nice setup you have there Ratte :great

I used a Blizzard 1230Mk4(50mhz) in my A1200T/Mediator Setup for a while before I got a 1240, then 1260/PPC and to be fair along with a Voodoo(or in your case Radeon) Graphics Card its very snappy indeed :)

Nice job on the mods, looks very nicely put togeter.

Thanks for sharing :cool

Steve.

What a very nice box you have! Nicely done. And the front USB port on the DVD case is just priceless! :D

[dannyp1]

I'm dying with envy! What a super set-up!

[mfilos]

Peepz mustn't have saw the outstanding mod of front USB on DVD-RW!!! What a clever and nice implemented idea man!
Your Auto switch is epic anyway, embedded to Radeon... is just pure win!
Keep up the good work man!

Am I understanding this right.... the Amiga is using the video cards memory as fast mem?

You are and that's exactly what it does.

What happened to the PPC?

[wXR]

So many questions!

1- How are you sharing this video card RAM with the system?!
2- Any stability issues there? Any video issues?
3- What is the max RAM available on these PCI Radeon cards?
4- Is the RAM any faster/slower than normal Z3 RAM expansions?

Some months ago I posted a detailed description to add the videomem by hand to the system.
Elbox added this "hack" to the pci.library v9.x (since 9.6 it also works on a1200) as a feature.
All you have to do is to tell the picasso-system how much videomem you will use for gfx.
The rest will be added to the systemmem automatical.
(radeonmem 16mb = 16mb for gfxcard and 240mb fastmem / for 256mb radoens)
No problems with videoquality.
Max. amount of videomem for supported pci-cards are RadeonPCI 92xx with 256MB.
(It is also the limit of the MediatorPCI-Bridge, which has to configured to 512MB in this case, because some extra memory is required for config and PCI-roms)
Speed of Radeon and ZIII mem is nearly identical, the bottleneck is the ZorroIII-businterface.

I send my defective CSPPC to a german (still active) reseller, it had still garante at this time (i think it had the 68k socket problem).
Many emails and promises .. but the card never returns, when i started legal actions, it was still to late.
The lawyers told me, that i had to act faster.
Even the last email/promises are from 2009 ... (card under repair since 2001).

Give my address to this reseller : I'll change the 68k socket for 30 euros + shipping back to you :great

Nice one ratte
nice use of some wasted space in the dvd drive, I`ll file that idea away, it might come in handy sometime in the furure

I`ve almost got all the bits to try the extra memory hack just need a radeon 92xx card then I`m all set to try your giude :)

Zetro asked a good question would u be able to use a voodoo for gfx and use all the memory from the radeon as fast ram, obviously this just a because we can kind of thing but still be interesting to know the answer

[Ratte]

I have no voodoo .. and not the horsepower to play with the idea of a 3d enabled system with 256mb memcard named radeon.
I am unable to answer ...

[cosmicfrog]

no worries ratte, I think it is possible to use the memory from the 2 gfx cards as fast mem
