Oh, such systems did exist long before Slot 1 era, see eg. Compaq SystemPro from 1989 - https://en.wikipedia.org/wiki/Compaq_SystemPr … Multiprocessing

Ahh! the Tyan S1834! Tyan boards are very solid.

Sounds like someone had a video editing system and a good credit card. ^.^

Well, as far as *desktop* systems with discrete CPUs... umm, maybe the 1979 Intertec Superbrain? Dual Z80s.

Non-desktop probably earlier servers. The problem is I'd have to go back and dig through early Byte and Creative Computing magazines page by page. I searched, but as usual the results were irrelevant rubbish.

It's hard to say because most of the "computer history" that's codified is also really narrow and only mentions a few of hundreds of early systems. You could find it with enough time to spend.

There were a number of early multi-cpu systems in the 70s and 80s, some with 3-4 CPUs, sometimes different ones.

If you have a wide selection of old and new hardware, you can see a massive progression in all aspects of the computer.

Old hard drives (the 10mb mfm kind) often have small cpu's on them.
old network cards used 8088 and 80186 processors
I have PCI IDE cards with 20mhz 286's on them

so a "multi-cpu" system is normal. 😀

But I'd agree with Grzyb about the Compaq SystemPro. I've never heard of anything similar, earlier.

If you want a very early OBTAINABLE dual system, look at socket 5. I would call those systems high end workstations and not servers.

Ah, that mysterious card with no video RAM...[/quote][/quote]

I've had CT65550 in laptops before, this is the first time I've seen one on an AGP card. I think it's a PCI chip, so it's probably just using the AGP slot as a PCI slot. It looks like there is 2MB VRAM on the card - does that make it the smallest AGP card ever? The odd connector on the bottom is LVDS panellink for driving pre-DVI LCD (or plasma) displays.

Old floppy drives too - Commodore 64 FDDs had more CPU power than their host system 😉

I'd say the distinction is symmetric vs asymmetric. Asymmetric co-processing is the norm and indeed used to be commoner than today, back in the time that CPU cycles were very scarce and almost every bit of I/O needed to do it's own thing in hardware. Symmetrically dividing up core processes, now that's the 'new' bit, at least on the desktop.

In the x86 world, but those So5 things were competing with pretty mature Sparc and PA-RISC solutions. I'd say 1992's SparcStation 10 was the first desktop SMP system. It - and particularly its successor, the 1994 SparcStation 20 - is still pretty easily obtainable.

I think Bob meant obtainable back in the day 😉 those Sparcs were out of reach of almost everyone - release base price in '92 was $19k in the US - though dual socket 5 wasn't consumer level cheap, it was quite a bit cheaper than SPARC gear

Hey, but they aren't "multi-cpu"!
CPU = Central Processing Unit
Sure, you can find processors (often in the form of microcontrollers) on various adapter cards, but then they aren't CENTRAL, they are PERIPHERAL.

The keyboard controller chip on motherboards (usually the biggest PDIP chip) is also a microcontroller as far as i remember. 😉

WOW! I'm surprised they sold it for that little.

I was watching that listing.

There's also a PCI version of these cards with an external (I think) 50-pin LVDS output. They are used to drive (and power) point-of-sale touchscreen displays. Siemens "Snikey" TFT monitors also use these "Plink" PCI cards as controller boards:

It never hurts to throw a low offer to begin with at a Best Offer on Ebay. Worst they can do is refuse it, but they will usually counter if they think it is too low.

I got half price on an ET4000 ISA card that way.

Occasionally you will meet a character that gets butthurt over the offering process, but you can always give them bad feedback or walk away from it (depending on if you end up buying the item or not)

I noticed there were no bids, and the seller had a bunch of other items for sale with no bids. I figured he would accept it. 🤣

How would you give them negative feedback? They sold it at a low price...

Well, not this one particular seller. Completely ignored 2 offers (weren't even crazy lowballing) without saying a word then ignored a message asking if anything was up. I wanted it anyway so bought at the buy it now price.

Later on I left negative feedback indicating his poor communication as the reason, because damnit, if I ask a seller something or make an offer, don't ignore it. Maybe I took it a bit too personally and that makes me a bad person here, but I'd probably do it again if the same sequence played out.

I attempted to make 2 offers on a sealed sound card and got rejected after a second hitting the submit button.

Seller must have a minimum Best Offer set, the system auto rejects offers below such.

And likewise they can put a min offer to accept and if your offer is above this, it would be accepted immediately.

Received this COAST module today. Haven't tested it yet, will do that later.

This was purchased on a whim really, I just bid on it on eBay and then forgot all about it. I was the only bidder, so I won the auction.

This module will be going in my old PC Chips Socket 7 motherboard with an AMD K6-2 500 CPU (underclocked to 300MHz) and I'll have to run some benchmarks to compare the before and after. That PC is currently maxed to 128MB RAM, so I'll have to remove 2 RAM sticks and leave it at 64MB to take advantage of the cache.
