Title: Cheap 060's and RAM?
Post by: JimDrew on October 20, 2012, 06:00:37 PM

I was looking at 68060 chips on eBay, and I came across a huge number of these:

http://www.ebay.com/itm/NORTEL-NT5D03FB-01-CP-68060E-128MB-refurbished-/130776132583?pt=Phone_Switching_Systems&hash=item1e72dd6be7

I found a reference to the 68060E and the pinout appears to be the same as the RC68060.  I also found a reference to an Atari ST accelerator board using these.  What I don't know is if the 68060E has the MMU/FPU like the normal (non-68EC060) does.  Does anyone know?

$14.99 for a 68060+128MB RAM seems like a good deal to me!

68060E may not be a full 68060.
Possibly missing FPU.

You'd have to ask to be sure, but the one without the FPU (or MMU) is the 68EC060 - I dunno if that's what they mean by 68060E.

More of a concern, I think, is that it doesn't look like any of the ICs on that board are socketed - unless the CPU is under that big heatsink (and maybe even then, as it's pretty low to the board,) it's likely a QFP processor, probably not something you could easily reuse.

Probably in TQFP package, possibly 3.3 V.

I can confirm that these are NOT TQFP. I have purchased several for component removal, and some are full 68060's, some are EC060s. They are full ceramic PGA components, but the sellers are not going to know which is which, unless they're willing to remove the clip-on heatsink.

ALL of this model Nortel board use the standard plug-in type of 060, not a SMT version.  You remove the 060 with the heat sink.  There appears to be to hundreds, if not thousands of these available as they were discontinued.  You just pull these out with the heat sink attached and plug them into another board.

The 68060E is not the same as the 68EC060, but I don't know what the difference is.

There's also a 68030 version but I couldn't find one below $60 USD.
