You don't fancy a BlizzardPPC then?

Yeah, I do. :-)

Can't afford it :-(

Bugger. I know the feeling - I want an A1 G4 XE. Still I reckon by the time I can afford one, everybody else currently waiting might just be getting theirs too :lol:

Anyhoo, a 68040 card is not a bad option. Even a 25Mhz 040 has considerably more poke than your old 030 for most jobs...

ermmm, I just realised this is in the Software forum - oops :-)

@Karlos

That's why I want the 040 :-D

Besides, they don't sell them in 030s anymore (well, I couldn't find any).  But the thought of the extra speed of the 040 is a bit exciting :-D

I got my first 040, an Apollo 1240, back in the day when they were a big deal (1995). I just wanted to play AB3D faster then...I've still got it somewhere. I'd sell it to you for a tenner if I thought you might actually be able to use it without it going wonky. It has a socketed ROM which seems to be a bit dodgy and is very fussy about SIMMs :-(

Hi Vincent

I gotta warn you it's not in good condition, the strain of a SIMM pushing against the ROM caused grief after a bit. It was an early revsion, later ones were much better designed. Expect the odd red or yellow startup screen. Anyway, it's 25MHz 68040/FPU/MMU, single SIMM socket, no SCSI. You can clock it to 30MHz reasonably but the FPU falls over sometimes. The fan is a bit puny and it's damn noisy!

That said, I have to find the flipping thing first ;-)

-edit-

Also, if any accelerator ever was going to have timing problems it would be this one :-P

Make sure you do get a 40MHz 040. 25 MHz 040's are still dog slow =).

Hey, my BlizzPPC setup has a 25MHz 040 still. It's not that slow for everyday use. Having said that, the PPC datatypes etc. may be helping :-)

I have and 040@33 and PPC@266 and when it boots (recognice the pcis) in the picasso mode it´s fast enough. Warpdatatypes rules!

Overclocked?

[Karlos]

Overclocked the BlizzardPPC, eh?

What about cooling? I dont have a fan on my 040 (but do have a big heatsink) - I couldn't if I wanted to, not without milling a hole in the side of my tower.

My old 040 card had problems at 33MHz, the FPU used to go manky after a few minutes.

The 030/40 that I've got runs at 7.11Mips (from sysinfo), so I know what slow is like ;-)

Well, to put things in perspective, expect about 19 Mips from 040/25, 25Mips from 040/33 30Mips from 040/40 and upto 80 Mips on 060/50 for superscalar code (over 100 for 060/66)...


My old 040 was my first accelerator. I didn't even have fast ram before that. The jump from 2Mb chip-only 020/14 to 16Mb 60ns 040/25 was just staggering...Happy days ;-)
