Knowledge gap. What board to use for adding Ram to A4000 ???

[Effy]

I have got a real A4000D with standard 68040/25. I wanna add Ram but don´ t want to spend lotsa money on a Cyberstorm yet. I am currently bidding on a Fastlane Z3 with 30 pins Simms. Isn´t there a card that accepts 72 pins Simms Is the only real option a turboboard I know plenty of my A1200 but as the title says, there´s still a gap in my knowledge about the A4000 ...

Patrik : thanx for the link, I found one line at the bottom that took me by surprise : " Memory on the DKB 3128 is not as fast as motherboard memory in the A4000, about 80% of normal A4000 memory speed according to AIBB. " ... I really thought it would be way faster than the 16 Mb I have now on board ... I must agree guys, it seems that an accellerator is the only option ...

Found this Progressive Peripherals 68040 for A3000 on Ebay for 51 USD and still two days to go, but it also uses 32 pin Simms ... and there is still that Fastlane Z3 for 35 euro that lasts an hour on Ebay ...

Now that you keep hitting on the bus-problem, what's the use of an expensive Powerflyer IDE controller then if the bus speed slows a lot down  :-?

If Zorro3 is backwards compatible with Zorro2, then why does Elbox design a Powerflyer (FastATAcontroller) for Zorro3 while there are other Zorro2 ide controllers on the market  :-?
I am also thinking about getting a fast ide controller but when I read your comments about pushing the cpu to 100% then it suddenly doesn't look so attractive anymore. Seems better to get a scsi controller and an ide-to-scsi adapter and hook up a 40 Gb ide harddisc to that ...

Thanx for the detailed info. I saw a Fastlane Z3 going on Ebay a few days ago for 51 euro, including a few mb's of 32 pins Simm's. Maybe it is better if I search for a cheap 68040 turboboard where I can put EDO's on to start with, and if possible also with a real scsi controller ...

I´m now bidding on a whole A4000 system with a Warpengine 040/40 mhz with 4 72 pins Simm modules, but with no scsi on board. But then I can still get myself a beefy Poyerflyer 4000 from Elbox ... even if that puts a heavy load on the processor ...

And I still keep an eye on this 68060 MK II on Ebay ... but there does not seem to be a scsi controller added ...
