    Time to figure out an adapter for CSPPCs and other accelerators that have socketed 68060s.

    But then again, the lack of an fpu is somewhat crippling.

    If the "MC68060FE133" is a rebadged MC68EC060FE75 that is able to run overclocked at 120 MHz then an MC68EC060RC75 (which wouldn't need an adapter) should do as well, shouldn't it?

    That would be worth exploring. I wonder if a custom math library could be created to make up for the loss of the fpu and how much of a performance hit that that tactic would create?

    Jim,

    For that matter, there are no 68060 chips in FE packaging, at least according to Motorolla's (albeit Q4 2001) product selection guide.

    @ boot_wb

    There are FE packaged 68060s, but this 133 designation is oh so dubious.

    Oh and get this, while I'm used to a few inaccuracies in Freescale listings, "Additional Features Floating Point Unit (FPU) Memory Management Unit (MMU)", their MC68EC060RC75 listing credits the processor with two features it doesn't have.

    Put out feelers for EC chips from distributors within the US (still a little scared of Chinese suppliers).
    I should have quotes by tomorrow.

    Freescale recommends http://www.rocelec.com for the MC68EC060RC75 and says they have inventory of "> 1000" of this chip.

    Wow! I couldn't get that link to work.
    Thanks Andreas.
    That quantity leaves some room for price negotiation.

    Direct link to all their 060RC chips:

    http://www.rocelec.com/about/searchresults/060rc/

    There're 1480 pcs. in stock currently. Seems they're differentiating manufacturer between Freescale and Motorola Semiconductor.

    Thanks Andreas,
    I asked them for a price quote too.

    edit - A company called US Bid just contacted me. They should have a price by tomorrow (although they also gave me a quote on HD6309EPs I'd been looking for).

    Well, even after a call from US Bid yesterday, no one has sent me any prices yet.
    I really expected that at least Rochester Electronics (Freescale's recommended vendor)would get back to me.
    Guess I'll give it a few days.
    It's not vital anyway as I don't have anything to test it in (the only 68K based system I've still own has an '030 in it).

    Only one of the suppliers I wrote to has responded so far, first with only a question of how many I needed, and then the second reply said that they did not have any available.

    I wonder if they became "not available", because I was also asking for where they came from, since Freescale claims they are not valid Motorola, or Freescale parts, and also asked if they had an MMU & FPU?

    Could be they decided they were not able to supply them because of the MMU & FPU requirement I imposed on the quote.

    I've received similar responses from Chinese suppliers. (asking how many were needed)
    I don't think they can meet the one requirement you made, as the Natami team's Sysinfo posts show that the "FE133" they have doesn't have an MMU or FPU.

    Thomas does claim to have received a stock pile of these though, so they must intend to build some '060 boards with them.

    Still no luck on the EC components. I'll re-issue inquiries later today.

    This was already shown almost two years ago with another software (see the last link therein).

    Over the past couple of years I've bought chips direct from Chinese Manufactures... If you sent your quote request to enough companies you will definitely get multiple quotes... I've found that sometimes only one company has the chip and 20 companies will send me quotes based on what they think they can get out of me after paying the "one" actual company that has stock. always worked for me to be patient and go thru all the quotes... especially for older chips that may not be currently manufactured.

    I know that the test results from the Natami team showed that their MC68060FE133 chips do not have MMU or FPU, but Thomas probably built only a few of these surface mount 68060 CPU boards with these chips.

    More than one of the sites advertising these chips show them as having both the MMU and FPU. The advertising is probably incorrect, and all of these chips are without MMU and FPU.

    Still, it is possible that Thomas and the Natami team could have bought a batch of faulty MC68060FE133's at a discounted price that were known to have non-operational MMU & FPU units, but I doubt this is the case. Surface mount parts are probably very difficult to test, until after they have been soldered to a board.

    You can get swappable sockets for them. Was looking at the possibility of this for repairing a cyberstorm in the past - allow swapping the cplds to find the faulty one.

    Needless to say the price put me off. (and the footprint was too large anyway). Useful for programming/testing qfp chips though...

    I've seen similar sockets for BGAs, but they too were far too costly to justify (unless used for testing purposes).

    Edit - First price quote in on 68EC060RC75 and I am dumbfounded.
    US BID will supply me 3Mhz Hitachi HD63C09EPs for less than $13, but they quoted me $400 for the '060.

    Seems a little steep.
    I'll have to look elsewhere.

    Interesting! So in theory, the manufacturer of these chips (if they are not rebadged slower Motorola units) could test each one of them in such a socket to determine if the MMU & FPU are working. Not that it is likely that this has happened, as it would be too time consuming, unless it was completely automated.

    Mounting the chips for the test wouldn't be that time consuming, but the test could prove pretty lengthy (especially if you wanted to test for max operating frequency as well).

    Freescale's recommended vendor, Rochester Electronics.

    PN: MC68EC060RC75
    Qty: 1
    Price: $595.61

    Qty: 50
    Price: $567.25

    Qty: 100
    Price: $486.21

    Mfg: Motorola
    Date Code: 02+

    Pricing is good for 30 days and all devices are subject to prior sale. Rochester Electronics adheres to a $250 purchase order minimum and a $50 line minimum. Terms and conditions apply


    Apparently current vendors rely on purchases from military contractors. Pricing on EOL products is unjustifiably high.
    As I would prefer NOS and want to avoid re-labeled Chinese sourced parts, I consider the 68EC060RC75 to be unaffordable for hobbyist pursuits.

    My vote for most unintelligible response so far from China.

    Hi there,

    Some supplier have the parts, so do we. However, we have the parts, maybe they don't. No matter where you're from, you'll like to cooperate with DHK.

    Just start with any enquiry, and easy to find the suitable supplier.

    Best regards,

    Landi


    Hi there
    Starts out bad and just gets worse.

    Aren't they fun? I think you win with that response.

    There were two suppliers that listed stock of over 10,000 MC68060FE133 CPU's, but I haven't gotten any responses from anyone who claims to really have them to sell.

    Chinese marketing?

    but no one has them for sale? Not surprising. But Thomas obtained a few, so there out there.
