Mega Midget Racer: Am I missing something here?

[AmmoJammo]

I have the TomThul 8meg fast ram between the motherboard and accelerator.

Workbench adds and recognises the ram.

Is it normal for the Sysinfo to be this low? Was I expecting too much?!?

:nervous:

Without the 8meg in (meaning only 1 meg total) it scored 580 dhrystones?

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.

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

Hi,

Show off!!!

This is what a 68060 looks like!!!

Yes a 68030 running at 24 mhz usually looks like that, you will see some increase in some games, but that is all. You can try some more ram, it might help especially for caching.

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...

Because, because? Its an a500?

It is because of CPU bus, when you have the accelerator plugged into your 68000 cpu socket you only have limited data bandwidth/addressing

Even with the 8meg plugged under the accelerator you are still crippled with normal access to the memory bus, really no faster than the normal 68000 cpu.

The pins on the right hand side of the accelerator are for its own 32bit memory bus addon board. Without this board you will be crippled.

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

Problem is NO 32bit ram in the system, just normal chip ram/slow ram

A serious handicap for any accelerator, tho you do get to use 32bit libraries compiled for 020/030.... you get no bonus speed

So, ah, i guess ill never find a ram module for this.

And 7.7 meg of fast ram, which is what the tomthul ram is.

[Azryl]

It is accessed as if it was chip/slow ram.. so no speed improvement.. sorry

The limit of 2 or 8 or more megabytes has no relation to the speed it is accessed on the system bus.

basically your lovely 32bit 68030 accelerator is stuck in the system bus access mud

[Azryl]

Oh by-the-way you sniped that accelerator away from me on eBay :p
I'm a sort of collector of A500 accelerators, not sure why... it just seems to happen!
