Old Atari CPU 90-6001 185 C27805

[GilesGoat]

I have this chip, it's not very readable, there's an Atari logo and says 90-6001 185 C27805, not sure about that '6001' could be '6081'.

It's a 40 pin dip.

I believe this is similar to an NTE6800 CPU which I am not sure but I think it should be equivalent of a Motorola 6800 CPU.

Is that the case ? Is it just a Motorola 6800 ?

Trying to look for a datasheet, if it's a 6800 I have it.

Does it look like the one pictured here?

According to Datasheetarchive.com, it's a 6800

No but I'll try to take a pic later, it's just standard black plastic 40 dip chip with an atari logo and the numbers.

According to various references Atari did apparently use the 6800 CPU in a number of old arcade games:

Supposedly they used it in some pinball machine computers as well.
