There are some small benefits to having either one.
Maximum RAM goes to Blizzard and is big benefit.
Maximum chipram access speed goes to Apollo.
Blizzard has some special utils for it written by Piru the Megacoder.
But that probably won't matter to u.
Maximum Mhz goes to Apollo. They can do 100Mhz or 105Mhz.
Either one can load your kickstart ROM into highspeed 32-bit FASTram.
I think, not sure, that u can soft disable the Blizzard 060 but still use the RAM for your 020. Hafta ask someone who has one or has read the docs. I haven't read about it for over 10 years.
I think, not sure, that when u soft disable Apollo 060 the cpu and RAM disappear from the system.
The thing is I have had my 060 card and I never once disabled it or wanted to. I luvz my 060 card. :knuddel:
Do u mean hard for u?
Or hard for Cosmos?
I donno what level of Hardware Wizard u r.
Personally I would just pay Cosmos to do it since he has done it a zillion times and knows what's what.
I donno but $500.00 last I checked. But that was a long long time ago.
They are worth every penny.
You don't actually get to choose what accelarator you get when it comes to 060. u grab it and run before someone else buys it.
They have not made new ones since 1990s. So u only can get one when someone dies or goes insane and sells theirs. Or when u manufacture one out of an old 040 card with the help of Cosmos Industrial Enterprises International Inc.
If u chant "Cosmos" 3 times in a row, then cross ur arms and blink your eyes (like I Dream of Jeannie) then click your heels 3 times and offer him a virgin houri then Cosmos the Mighty will magically appear and tell u how much he charges to upgrade an Apollo040 to an Apollo060 and add the 2nd SIMM slot with memory that actually works. (both SIMMS must match).
Then u can have an 80Mhz or more 060 card with 64MB and be kewl :cool:
like the rest of us 
If the Apollo 040 is cheap then I will buy it and hire cosmos to upgrade the hell out of it and give it to a friend of mine who can make use of it.
Ok.
I guess I'm going with that Apollo then.
The RAM would probably be hindering anyways. Nothing worse than coding and testing apps on a machine that has more RAM than the average person's machine.
When I said hard, I meant hard for my former boss (whose an electronics geek). If I tried to modify it myself, I'd probably destroy it in less than 5 minutes.
Cosmos is probably located in the US, right? Don't think I'd want to send a piece of hardware over the pond.
Edit: As for disabling the CPU and still retaining the fast RAM: That's pretty non-sensical, isn't it? I don't think any 68020 programm requires that much RAM.
Furthermore, I could always add one (multiple, even?) Radeon 9xxx series cards for an additional 256+MB, right?
