Motorola 68070

Probably, someone else has asked about this before, but i was sleeping, drinking, fishing or something.

A company in Norway/Sweden sells these prosessors for less than 400,. Norwegian Kroner. (= 50$)

There is still a (although perhaps very very very little) market for accellerators with 68060's... is there so much work making cards compatible with this prosessor instead?

Just wondering... because i would probably buy a 68070 axx card for all my 1200's wich i use to run Scala Infochannel presentations.

If my memory serves me, this is an integrated CPU
with I2C interface and stuff, and is in the 68010
performance range. in other words its slower
than the CPU in a bog standard A1200

i think the 68070 is some old cpu made by another company that wasnt really very compatable with the motorola range

and it was very slow too!

The 070 is not what its name would imply.

To the best of my knowledge, it's less powerful than a 68000. I think it was used in the CDi. There's no benfit to building Amiga accelerators around it. They'd be decelerators.

Why Motorola continued higher numbers with a weaker chip, I have no idea.

im sure it was another company

*sigh*

oh'well...

Infochannel runs so much more smoothly on at least a 030 cpu, compared to a stock 1200 with 4Mb fastram. (Elbox).

Does anyone still produce 030 axx's?

Decelerators...that has a certain ring to it :-)

Phillips, I think.

All the incompatibilities with none of the speed!  :-D

Anyhoo, if the coldfusion accelerator project comes to fruition, it would be interesting to see what sort of performance a coldfire v5 core would deliver for existing 680x0 machines :-D

See here...

Sounds to me like you'd need an airbag for that kind of deceleration...

As mentioned before, the 68070 is an 68010 (or even "just" a 68000) made for Philips by Signetics (IIRC) for the CDI. Not much use for Amiga users, AFAIK..

some bits

Some more

(Looks like the CDI was popular in Germany, many german links when you look up CDI 68070 ;-))

(edit)

"68070 16/32-bit microprocessor

CMOS microprocessor which is fully 68000 compatible. It contains, except the CPU, MMU, 2x DMA, UART, I2C-interface, 16-bit timer, interupt handler, clock-generator, etc."

I'm 99.9% shure I've seen those as Motorola brand. Perhaps Philips bought it to secure availability. Even comes as a 84-pin PLCC so I guess they must go into new stuff aswell.

@JetRacer,

Couldn't agree more :-D

Sorry, in a silly mood  :crazy:

-edit-

Do'h, he wrote something there now :-)
