[@sedrosken831]

I've got a few notable facts about the blue lightning actually: - Being 386 derived, it has no built-in floating point unit, and uses a 387 math coprocessor socket. - The design stems from their 486SLC design, which was a similarly souped up 386SX, and thus has a couple of quirks inherited from that design, namely an inability to cache more than 16 MB of RAM. At least you can actually access more than 16 MB with one, though. It has 16K of L1 vs the SLCs 2K and the regular 486DXs 8K. - Again, because it is 386 derived, it has issues being detected by most software identification utilities. I've seen many humorous interpretations made by various packages. I think my favorite one thus far was when mine was detected as a 68 MHz 486SX. Most software will compare the instruction set with how long it takes to complete a specific instruction to determine clock speed, and because the blue lightning has execution characteristics of a 386 with the instruction set of a 486, software can often end up confused. It doesn't help that the real blue lightnings never supported the CPUID instruction. This one isn't actually a fact about the blue lightning in particular, more an overview of all of the IBM specific chips, but due to their licensing agreement with Intel, they could only sell CPUs as part of a major assembly or whole machine so anything you see with a blue lightning was made at the very least mostly by IBM. They tended to pair excellent supporting hardware with it in their day, for example, my board has excellent local bus IDE, a floppy controller, parallel port and dual 16550A UART based serial ports onboard, a rarity at that point in time. The 16550A UARTs are notable because a lot of companies still got away with using 8250s and the 16550As were capable of much higher baud rates.

In the early ‘00s I convinced my parents to buy an IBM desktop PC from a newspaper ad. It was a basic Pentium III Celeron with a microATX motherboard, black and blue case with IBM badge. Shipped with XP or ME, ours had XP. I remember being curious back in the day as to why some places (BIOS and drivers) referred to it as an “Ambra Ispirati” rather than an IBM. I guess Ambra lived on in some form within IBM Canada until at least 2001.

I still have (and love) this machine, and have now upgraded it ever further (you can find it on vogons if you search for it). Let me tell you though...You could NOT remove the HDD without the key. It was mounted on a rail and would ONLY slide out backwards.

[@RJ-vb7gh]

I vaguely recall taking a look at a blue lightning mother board at a computer show... as I recall it had an awesome clock speed for the time, around 100MHZ but that it was only a 16 bit chip. The vendor claimed that it was designed to take older legacy applications to a new level rather than something for either new users or folks that wanted new stuff. In other words if you wanted to stay in the DOS world and run your old Dos apps really fast, this was the processer for you. To be honest, I had a lot of customers at that time who were running businesses in the dos world and really didn't see a purpose for windows or fancy bells and whistles. In fact, I think I serviced the last Dos machine in around 2005. It was an older gentleman who made his living as a writer and he was very happy with his old dos word processer and had no interest in learning anything new... So yes I do believe there was a market for the blue lightning in certain business applications and for a relatively short window of time. Imagine Lotus 123 1.0 at 100MHZ... wow.

[@georgegrubbs2966]

Fantastic video. I'm amazing at the apparent time and effort it takes to produce a quality KZbin video like this one. Well done. As a card-carrying computer pioneer (starting circa 1958), I followed this video with great interest. One thing to mention about IBM's exit from the PC business is its diastrous and hugely expensive operating system, OS/2. While this was a feature-rich OS, it proved to take too much power and memory to operate efficiently, plus users perceived it to be an proprietary IBM product that would run only on IBM platforms. I understand that OS/2 eventally cost IBM a loss of over $1 billion. Meanwhile, Windows 95 (I believe) was becoming more mature and users flocked to it in droves as it came bundled with PCs. An initial and huge mistake IBM made was not retaining the rights to MS-DOS which Microsoft developed under contract to IBM. Actually, IBM would have done better to engage Digital Research and their CP/M OS. Why that didn't happen is an interesting story. The rest is history,.

[@greggump9923]

I remember that!. I LOVED OS/2, once the quirks were understood. I was also familiar with DR DOS, but not so much with CP/M. I worked for TI beginning in 1973, on their geophysical systems, then their TI 990 systems, then the TI PC, with Rod Canion before he left to form Compaq. I stupidly turned down his offer to go with him to Compaq, thinking PCs were still toys compared to the multi-user systems I had been working on.

I still have my first 1976 computer. It is a Poly 88 from PolyMorphic Systems. Ah yes, back in 1976 I got my first dose of an S-100 based bus system computer. I found an old small TV an turned that into my computer monitor, and threw together my own keyboard. Program storage was recorded via the use of a cassette tape player. My 1986 Heathkit Hero 2000 robot is still working, so things really can last quite some time if taken car of.

[@xcoder1122]

Fun fact: As the US constitution requires a census every ten years and this took longer and longer the bigger the country grew, inventor and engineer Herman Hollerith built a machine that would automate parts of this task. Input data would be stamped onto punch cards (a technique already used by looms at that time) and a machine with multiple counters would then collect and count this data, way faster and less error prone than counting anything by hand. This was so successful that he founded the Tabulating Machine Company in 1896 to produce more of those machines. Later on that company merged with two other companies to become the Computing Tabulating Recording Corporation: CTR. 1924 this company renamed itself to IBM.

[@MeiinUK]

Wow.... I never knew that..... Since 1896s ?... It would be a very tough way to get people to understand the knitting patterns and techniques to be associated with computing.

When I first got mine it had only 8mb of ram and a 400mb or maybe a 440 hardrive. It also cost me $5000.000. I don't remember if I had to add more ram for Windows 95 but when first bought it it had dos 6.22 and Win 3.1. I had computers before this that my parents bought me but this is the 1st one I bought. I can remember playing Doom with my neighbours after I got a modem. Sound Blaster 16 also came with it. To install windows 95 you have to turn that virus checker off or 95 wont install. I think I had to finance mine or I paid for the bloatware that came with it I got swindled because mine cost me 5k but it came with so many cd's and 3.5 floppies.

@@lassikinnunen The fun part about that clause as I understand it, is that they were completely free to sell it as part of a large assembly like a motherboard. So they did. Note how you never see those CPUs loose, it's not just because they have to be soldered. As for why, They can manufacture those for cheaper than Intel would sell them real ones, and they can reuse some older designs. Plus they were quite competitive, with that extra level one cache they could usually go toe to toe in whatever you wanted productivity wise with a real 486DX2. They didn't hold up so well in games, but they didn't exactly have a poor showing either. The later Cyrix designed ones aren't subject to those same limits, and being able to brand some as their own was literally a term of the agreement they struck with them. That lasted through to the 6x86 era.

@@lassikinnunen As I understand it, the licensing deal originated back in the 286 era when Intel was still okay with second sourcing agreements. IBM just took a mile when given an inch and their volume was so relatively low that I'm guessing Intel didn't consider it worth their time to litigate it. As for limiting them, I'd say they were pretty effectively neutered by being stuck selling them as whole packages with motherboards.

The big, big price drop came from highly integrated late 80’s 286 boards and early 90’s 386 boards. Early 286 boards had monstrous amounts of chips on a large mainbord; later 286 and 386 had like 3 big chips, a clock, some cache and some memory modules. 386DX-40 was extremely common, very cheap and powerful enough to play the three amazing games of 1992 and it came along at just the right time as cheap and somewhat useful sound cards replaced PC speaker. The three must-have games of 1992 was Wolfenstein 3D, ultima underworld and Ultima 7. Ultima underworld is such a technical and gameplay achievement that is almost as impressive as the 1969 Xerox presentation of the computer mouse, windowed personal computing and teleconferencing. The closest thing to ultima underworld were space games like Elite; but they weren’t really that close. I’d go so far as to call it the first immersive game of any kind.

You talk like IBM losing market share was a failure, but I thought it was well played. They got in when it was new and had high margins and got out when it was commodity with low margins.

[@dennisfahey2379]

Really the phenomena of IBM losing the PC market they created was a failure not of IBM but of Wall Street. Its a pattern we see time and time again. IBM had grown the market and was under attack from companies willing to accept far less gross margin. The volume of PC's sold was growing almost logarithmically. Brilliant Wall Street analysts saw this and hyped the stock at first then pivoted when the inevitable price wars occurred. In other words the market commoditized. This of course is great for the consumer however it meant although IBM made more money overall on the market it was at substantially lower margin per unit sold. Wall Street Analysts demanded IBM exit the market as they wanted to see upwards of 65% or more gross margin - what they had seen for a brief period in the beginning of the new sector. That was terribly flawed "first order" thinking. As such IBM was forced to exit even though they made tremendous bottom line revenue AND retained a great "moat" due to their internal innovation capability. (IE the IBM R/T RISC computer etc. ) It is a classic tail of opportunity lost due to external forces that were not competitors. What analyst has ever made a product? And note the IBM R/T RISC computer was capable of running the licensed Apple Mac OS and its GUI. (It was based upon IBM's POWER PC architecture.) My theory is while the ankle biters were killing eachother making the same box - IBM would have dominated selling solutions and continuing to define the market. If they were only allowed to do so. Unfortunately they had to exit to appease the great gods of Wall Street and thousands of good paying jobs were lost. Of course IBM made a comeback a decade later selling blade servers to the new Internet datacenter market. These were virtually the same tech but had better margins.

Can confirm early Blue Lightning cpus were built within the 386 design specification and licence. They’re usually a qpf132 that can be connected to 100 or full 132 active pins and will switch between 16 and 32 bit external operation depending on bus width. Rumour is 24 bit also works and ram configuration in some weird boards supports this. Chip is a 3.x volt chip but is rumoured 5v tolerant. 2x and 3x multipliers available and max speed supposedly 33.3x3=100mhz though IBM rated at 3x25=75 official max. Spec of the top BL3 included 16kb cache, 3x multi. All have a handful of additional 486SX instructions for compatibility. Transistor count, package, ALU behaviour still 386 territory. But yes later ones were just 486DX2 chips nothing special.

Oh funny the insides look surprisingly simliar to my IBM PS/1000 Blue lightning My version is IBM branded though and it was made (apparently) as a low cost/high profit margin PC to be sold exclusively by a retail chain called Media Markt in Germany (or maybe even europe... not sure) I don't know about the mainboard in your machine, but the daughter board in it looks exactly the same as on mine.

I've had several IBM machines from this era that have this same weird expansion card riser board. I guess it enables having a bunch of ports flat on the motherboard while still having a full compliment of expansion slots. Stacking the IO ports as is done with ATX seems an obvious and obviously better design. *shrug*

I remember very well FDIV mitigation in Linux kernels in the 90s (I was a relatively early adopter.) The F00F bug soon followed.

Hah, interesting about Linus's Ambra... I knew it was a 486, did not know it was Ambra. My first Linux box was a 486DX/33mhz with 4M of RAM.

[@mercster]

Heh... surrounded by other IBM PCs, aaaaand one lone E-Machines Hackintosh there on the end. ;-)

[@ohasis8331]

Had never heard of the Ambra till just now. I was the envy of my friends as I had a DX2-66. at the time.

Nice video, how is the drum & bass track called please?

Up until the early 1990s, many computers were made in the USA. With that said, I'd like to see a video about US factories, including locations.

A opti chipset. This reminds me to something special from '93. I had a 486dx33 on a opti motherboard with opti local bus. Opti local bus was 32bit eisa slots on 33MHz, this combined wit a opti et4000 vga card and a caching diskcontroller with a 16MHz amd 80186 and 1MB ram just for pumping data (240MB seagate). 4MB ram for the processor, try that in these days. At that moment the 486dx50 was the fastest intel consumer processor.

This song is awesome! 😎 What's it called?

[@lannik_0]

OMG 😮...I totally forgot about old cases being one piece you had to pull from the body... Now it's all coming back in flashes

Predominance of beige as well.

It seems, the CD-Rom is hungry :). Thx for the great Video!

"And amazingly this [...] survived long enough" the lab I did my minor had an apple ii, a dos computer, and an OS/2 😂 university departments are like Hotel California for PCs, they can always enter, but they'll never leave 😂

[@jojoanggono3229]

My first PC was with a CPU that came before 80286. Can't remember the name, 8088 perhaps, with DOS. Can't remember which DOS, if I'm not mistaken there was PC/DOS and MS/DOS.

IBM essentially made a template for how to make a clone PC with fairly intricate details. They realized their mistake and tried to correct it with the PS/2 which was a lot more locked down. But it was too late.

12:55 i was like i never seen those reminder options, then u ask if we ever seen them lol, nope

[@WindowsSurfaceOffical]

How the heck do you boot into the bios on the IBM Ambra DP90 Motherboard

[@waytostoned]

I would love to restore that cdrom drive. I'm very active on VCFED. ;)

6:02 bode mastigando? Ou é a inteligência artificial agindo?

[@slycooper1001]

i have a device that matches that shutter door it uses a standard drive bay i wanted to find at least a functional tape for that tape streamer

[@BENDER_TECH]

Amazing content.

[@mybachhertzbaud3074]

The only PC that looked like that thumbnail, I've never heard of. Is one that didn't need to reboot constantly.😜

[@waytostoned]

The mouse became the Packard Bell mouse in the 486/Pentium days

[@intel386DX]

Very cool POST

[@gyrgrls]

I remember when this model disappeared without a trace. It was the first Ambra Alert.
