Mega Midget Racer: Am I missing something here?

[amiga-penn-wchester]

That's totally wrong given a 68030.  I'm not sure why?   Maybe you found a bug or "assumption" in SysInfo?

There are plenty.  Here is what it thinks a 68060 is in an A1200T.

[amiga-penn-wchester]

also, why are all your libs in chipram instead of 32bit ram?

[amiga-penn-wchester]

A 68030 should look like something close to the A3000 benchmark on SysInfo actually, unless I'm missing something.

[amiga-penn-wchester]

The point is that SysInfo is reporting a 68060@50mhz to be over 300mhz... it isn't accurate at all and it's hard to resolve someone's problem with just sysinfo...

[amiga-penn-wchester]

Oh, if you have no mem on the accel (mega midget racer is supposed to support 32 bit mem) and just something in between, then I would assume that that is normal.  

Most amigas show little to no improvement without 32bit ram right on the accelerator, even a 68040, 60 etc.  

Add to that sysinfo doesn't count correctly either.  

Apologies, though,  if I'm misunderstanding your situation

[amiga-penn-wchester]

it would be a hard find, most were coupled with the accelerator itself, not sure what use one would have for just the expansion board.  

I looked in to getting one when I had an A500.   They are usually sold w/ the mem attached, perhaps you could purchase another cheap w/the memory if the price were right.

[amiga-penn-wchester]

If that's true, he should see a larger sysinfo dhrystone number, as inaccurate as that would be...

throwing kickstart into fastram vs having 32bit ram is... well I've never measured such a thing!

[amiga-penn-wchester]

I havent looked in to how sysinfo works, programatically, but i know that beyond 68040/25 it doesn't make much sense.  Or beyond what was thought of as "stock" amigas at the time...   I'm sure there's someone here that can enlighten us on that one.

AIBB was a competitor benchmarking program at the time when I had a fast amiga, perhaps it is more accurate... I don't know.

Regardless, it's been said many times - an accelerator on the cpu slot w/ no memory isn't much better than no extra cpu at all...

[amiga-penn-wchester]

yes, I agree, if there is 512k up for grabs on it, and it can be jumpered or something to be 32bit RAM, you should see a noticeable increase in speed. (however you measure it)   Unfortunately, I don't know a whole lot about this accelerator in general, but I'm just speaking about how amiga accelerators behave in general.

I can say that A) a microbotics 030 with no RAM is as slow as a stock A1200/020

I can say that B) an Apollo 040 with no RAM appears to be slightly faster than an A1200/20.  

Add some SIMM memory to these boards and the CPU comes to life

[amiga-penn-wchester]

what happens memory-wise when you select 68000 fallback mode?
