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?

[AmmoJammo]

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

Because, because? Its an a500?

[AmmoJammo]

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

[AmmoJammo]

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

Az

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

[AmmoJammo]

By 1 cent...

[AmmoJammo]

Yep, but that accelerator should have memory.
Just 512k, but that's memory and it should help a lot...
I'm wondering if it's not enabled for some reason.
(Setting or conflict)

desiv

its optional, as per this link:

http://amiga.resource.cx/exp/megamidget

and doesn't have it either.

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

using the hardware switch, it crashes... won't boot, have had the "red screen of death" as well as another error...

That's if it does anything...

[AmmoJammo]

I know the kinda benchmark score it'll do with the extra memory, google seems to find that

I'd also seen results that were low, like mine, but the pages weren't in English, I can only assume they were lacking ram :p

just been playing with my A500 again...

it seems I can plug the 8 meg tomthul ram between the motherboard and MMR, OR, I can plug it into the MMR 68000 socket, and workbench can still add and access it...

question is, can I plug it into the MMR and overclock the ram to the same speed as the MMR, rather than running it at the same speed as the system bus?
keeping in mind that it just crashes when I attempt to run in 68000 fall back mode anyway... so I'm all for cutting tracks to the 68000 socket on the MMR and running wires! :p

TomThul 8meg, 512k inbuilt, 512k trapdoor configured as chip, and 512k on the Mega Midget Racer...



Thats more like it! :hammer:

[AmmoJammo]

33Mhz crystal? I changed the scale, but you get the idea :p

[AmmoJammo]

I still have the issue that the MMR won't run in 68000 mode?
whether hardware switching, or software?

do you think the accelerator card may just be faulty?

I get the software error screen, with the flashing red box around the red text?

Another time I just got a blank red screen? "An error was found in the ROM."?
and a flashing power light.

I've tried two different CPUs, 68000 and 68010?

thanks!
