I have four 32MB SIMMS in mine. The largest SIMM it will recognize, IIRC, is a 32MB. I'm pretty sure what you have listed as an example is fine for the type to use. And, yes, leave the ZIPs in place. The BigRAM can probably be repurposed to some other Z3 machine that is in need... 128MB on a machine of that vintage is plenty.

I modified my A3000's drive sled for mine, which was originally an 040 version that had a heat sink on it. I cut a nice, neat hole for the heatsink to fit though, which worked fine because I don't have a second floppy in the system. I upgraded it to an 060 and even though the 060 doesn't need the heatsink, I added a Pentium sized heatsink and fan, because the A3000D's airflow isn't that great.
LoL! I saw that thread yesterday and was ready to post some warning about A3000 isn't that great for accelerators because of not so great air flow. I had Cyberstorm III in and it was hot until I did something similar - I remade A3000 tray/shelf in aluminum with a nice big hole for heatsink/fan:


I sold my CSIII, so it is unused and Intric8 if you need it, PM me.

The maximum is 128MB, more is not allowed for CPU-Slot cards.

OMG what a steal of a deal! :o Even damaged non working CS's sell for $5-600 USD and I've seen my CS-MKIII selling for between $2k-3k with ease the past few years

eBay sellers in the United States are not posting worldwide because of the pandemic causing shipping times to be extremely slow. I too am only posting in the United States until things get back to normal.

I had gotten in many of those Phase 5 Cyberstorm MK2 boards through the years. I remember getting one in each of the five Amiga 3000T computers that I had gotten in. Since about 99% of all Amiga software does not take advantage of that board, I sold all of them to Amiga fanatics puffed up with ego They usually sell for $600 to $800 each. That's what I got for them. Remember, most Amiga software runs great on a STOCK Amiga 500 computer with 512K of Chip memory and 512K of Fast memory. Many people allow their ego to cause them to spend way too much money on this vintage computer hobby.

You are not going to believe this, but, the best processor board for an Amiga 2000 is a 68020 board. Once you go past a 68020, you lose a lot of software compatibility. This is the reason why Commodore installed a 68020 in the Amiga 1200 computer. The only "upgrade" that you actually need is more Fast memory, and this is only if you plan to use Workbench 3.9 in 256 colors mode.

Oh, some Amiga games require at least 512K of Fast memory.

Could you give a specific example why the 68020 should be preferred compared to a 68030?

AFAIK the 68030 should be the best option for the 68k line for offering best compatibility and maximum speed options.
