After a while opening the tower and looking that WEB, here's, a bit better, what it's inside:
1.- Phase 5 digital Products CyberStorm Mk2. Those 3 memory banks are inserted in this card. I haven't tried nothing about this.
ShowConfig says:
Node type $A, Attributes $505 (FAST), at $8000000-$BFFFFFF (64.0 meg)
Node type $A, Attributes $703 (CHIP), at $2000-$1FFFFF (~2.0 meg)
A question: if I unplug this card, the Amiga would work? Because it's the CPU what you're removing but, on the other hand, this is an expansion card. Should 68040 work in that case? Do I have two CPU's?
By the way, it should be a 68060@50 mHz. Running the bench SysInfo, it reports me it's 2'05 times faster than a 68040@25 mHz. I think it should be more because the frequency is doubled (25 ---> 50) and my CPU is better (040 ---> 060). What do you think?
2.- Phase 5 digital Products CyberSCSI MK2. Nothing to mention.
3.- There´s something more. Behind the CyberStorm Mk2 and Micronik 6960 cards there's another big one I can hardly see.
Micronik card is screwed to the tower. By unscrewing it I will be able to see the big card and get more info but this scares me a bit. Everything is working quite fine now and, in that situation, removing it... pufff.... It is supposed this big card has 16 mb leaving 48 to the CyberStorm? I'm a bit confussed with this card because I thought it was the motherboard (CV and IV can be inserted in it) but now, I don't know.
CyberStorm should be plugged to the big card. I see no screws for it but the back side image of that card says so.
From what you show, there is 64Mb on the cyberstorm accelerator(you cannot remove this,it IS the cpu and without it the machine will not run).
judging by the sysinfo output there is no ram on the 4000 mainboard(which is correct,its best to remove this ram and use only cyberstorm accelerator ram because its quicker).
There is 1 simm on the 4000 board for the 2MB chip ram,which is different from fast ram.
The cyberstorm also can be upgraded to 128Mb with 4- 32MB simms.
Technically you don't have a real commodore A4000t. you have a desktop A4000 motherboard in a micronik tower with their custom slotboard.
Generally "A4000t" refers to the commodore/AT/quikpak towers.
but we knew what you meant
Doubling MHZ does not necessarily mean double the performance. this is normal.There are more factors in performance you have to consider.
Sysinfo was written before 060 cards were common or popular and generally is not going to give a good reading.
Take sysinfo results with a grain of salt, we often nicknamed it "sys(MIS)info"
Its good for quick and dirty tests but i wouldn't bet the farm on it.
try "WhichAmiga" from aminet to find out the exact cpu and revision.
the "large" card under the micronik board is the main amiga motherboard.
