Chinese 68060 Rev 6

[alexh]

China are not making any new 060 CPU's. They are being reclaimed from routers or warehouse clearances of NOS.

As for them making new ones. They don't have the mask set, the fab, the stream file or the source/schematics. We won't be seeing them making clones.

What you have to look out for are 040 CPU's marked as 060 CPU's or earlier 060 CPU's marked as rev 6

It's pretty easy to spot them.

Insist on a non-stock photo. Most of the adverts on ebay use the same photograph over and over. Insist on a photo of the item you are buying.

All FULL rev 6 parts I have seen are marked MC68060RC50 if it says anything else then you have to think twice.

The earliest rev 6 parts were manufactured in 1999. If the date code (four digits, two for the year, two for the week, i.e. 9952) is earlier then it is questionable. The latest I've seen were 0140 (2001, week 40).

They have the Mask number E41J. Most are prefixed by 71.

I'm pretty sure their guys that built a home grown MIPS would have something to say about that

I bet you serious money that either :

A) They developed a 20 yo MIPS, fun but practically useless in modern applications.
B) They stole it.

The modern MIPS is available as RTL code, easily stolen and re-used, the 68060 was created using schematic capture for a fab that no longer exists for a technology that no-one uses anymore using tools that dont exist anymore. Even if you had the source it would take man years to convert. Even if you had the masks you couldn't make more as the FAB that used them closed down years ago and non of the modern FAB's use compatible process techniques.

Believe me, they did not reverse engineer and re-create a 68060. The documentation is extremely limited on how exactly the 68060 works.

Plus there is no market for volume 68060 chips.

what are you planning to do with them?
Upgrade an existing 040 board?

Or overclock an existing 060 board.

The FE is the package type.

RC = Ceramic (MC68xx060RC = 206 pin PGA)
FE = Plastic (MC68xx060FE = 208 pin CQFP)

I am pretty sure they never made any full MC68060 in FE only the LC and EC.

Later model Apollo 1260's used the FE variants and a PCB adapter to convert them to PGA pinout.

I am also pretty sure they never made anything faster than an MC68LC060FE75

I'd be curious to see a picture of a fake FE133

thats a real 68060 well done!

I'm pretty much sure that's an RC50 that has been re-marked. The number along the edge doesn't correspond. Although I have to admit that there is very little information on them.

Anyhow they are identical internally to RC50 and so cannot realistically demand a higher price.

I've seen several MC68060RC60's marked S23328-002 but non marked S23328-004 but I've only got a very small sample set (3)

http://www.icphotos.org/photo/MC68060RC60-large.html

Whereas all my MC68060RC50's (and I've got a lot manufactured over a large time period!) are all marked S23328-004

Admittedly I have no idea what this number is.

It is marked down the side as S23328-006, and up the top as 71E41J QQDJ0429C MALAYSIA.Also instead of the Motorola logo it has the Freescale logo.

Oooo. Photo required :-o

Is it possible to just simply pop this into a CSPPC or a CSMK3?

Yes as long as it is an 060 version. I think there are 040 versions of the CSPPC which require moding, jumpers changing, voltage regulators replacing etc.

Calgor wrote:
Do those have 68060 sockets?

Yes but they are very, very, very fragile. Take care not breaking it when removing and inserting the CPU as the repair is ~€150 at Amiga repair center in France.

Why on earth did they not use a "thru-hole" PCB design?

Just thought I'd let you guys know I got a MC68060RC50 off the same lzf guy on ebay instead of the Motorola logo it has the Freescale logo.

Where is the photo of this?? Come on, use your phone or something.

G59Y mask set means it is quite old.

This is an EC part (no FPU or MMU).
