    When I was a kid, my parents delayed buying a (much needed) new car to buy a home computer. They bought a Leading Edge Model D. Paid something like $500 extra to get the full 640k of RAM. Our was dual 360kB floppies. Later my dad brought home an IBM PC-XT from work to be his "work from home" computer (MDA video card, 20 MB hard drive plus dual 360kB floppies,) so the Leading Edge got to come to my bedroom instead of the basement/family room. I bought a Hard Card (20 MB hard drive on an ISA card) and a modem for it, and BBSed the nights away!
    We even had two phone lines - the second one so my dad could dial in to work (yes, in the late '80s!) I got caught BBSing in the middle of the night on the main phone line, so I ended up illicitly running a phone cable from the basement to the upstairs to my bedroom through a furnace duct/vent so I could BBS on the second phone line.
    Between then and high school in the '90s, my parents brought home from their work a Compaq Portable II (to keep, it was being replaced by an early laptop) a PS/2 Model 50 (replacing the XT as my dad's work-from-home computer,) and a PS/2 Model P70 (the "luggable" model with the large red-gas-plasma screen - also to keep as it was replaced by a laptop) which replaced the Leading Edge in my room (plugged in to a VGA monitor I bought myself so I could have color.) In high school, the "family PC" got upgraded to a later Leading Edge 486. (My dad's work PS/2 got moved to another desk.)
    The 486 wasn't very impressive. (Although I did end up upgrading the RAM, hard drive, modem, and video card myself.) Leading Edge had been bought by that point, and was just yet another generic PC maker by that point. (They were one of the earliest "low cost PC clone" makers back when we got our first one.)

      Don't underestimate the keyboard!!! Many people still think IBM model Ms were the best, and they were bundled with Personal System/2. $400 and up for them now, which in most cases now is much more than the rest of the PC.

      @@squirlmy Model Ms routinely sell for $50. There was a time not long ago where they were all $150+ though. There are millions of them out there, and a lot of people don't particularly like them (they have their diehard fans). Even the superior Model F can still be had for less than $400. These Leading Edge boards are worth good money for their switches alone. The DC-2014 keyboard in this video is guaranteed to have SKCM blue Alps switches, which are probably hunted by enthusiasts second only to IBM's beamsprings. I rarely see them sell for less than $200-300 anymore.

    Oh god... Its the Leading Edge PC!! That was my first PC that I ever owned from the late 1980s running on an 8086 CPU. I remembered that computer and had fond memories. I remember being able to put MSDOS, and all my utilities into one 360K boot up disk before I got the 1.44M floppy drive. Who would ever forget the Leading Edge Word Processor program? The glow of that green CRT monitor still brings back memories. I remember trying to code color ANSI screens for a BBS. It looked okay on a green monitor, but when I first saw it on an EGA monitor, boy, those ANSI screens were ugly! Even though I had a C64, that IBM PC was used a lot more due to BBSes in that era.

    Adrian, the leading edge model D was revolutionary for its time. I still remember my father’s friend who got one. These were affordably priced quality PCXT clones. They had a smaller case than the IBM PC, they had front mounted power/reset buttons and keyboard connector, a real first for it’s time. They sold thousands if not millions of these things during the mid 80s. Leading Edge even sold their own branded word processor as well.

He ended up returning it because of some incompatibility (likely Lotus 1-2-3) and swapped it for a NEC 286.

      Obviously even with 30+ year old computers the original owners might still be alive and it's good form not to dox them if there's extremely personal information (i.e. finding a diary instead of a ship's log), but I hope old hard drives do get preserved well enough that 50+ year old ones can tell stories from the dead in the same way we learn about the lives of our ancestors from old books.

I'm reasonably sure the keyboard was identical to the one you've got here.

I didn't know they had batteries inside, so now I have a project to get them out. I bought them out of curiosity. I have an older brother that had a Leading Edge clone that he used to do his doctoral thesis. Also, I went to a Leading Edge dealer with my dad in the mid 1980s where we looked at these machines.

I had a CGA monitor for my games, and my mother kept the monochrome monitor for her word processing.

When I was researching Minix, I found an old Info Sheet that mentioned the Model D worked well with Minix. Great System - I swapped out the onboard UART with a 16550A and put in the XT-IDE Card. If you google, there is an 8088 BIOS called Super XT. I run that now and it works great. Only downside is that the built in Video doesn't work.

    This is the first PC I ever used! I played Basstour and LEWP (Leading Edge Word Processor) and Nutshell (database I think) on my grandfather’s Model D! I had no idea it would support a 3.5 floppy drive, we were told since it was a clone it wouldn’t support one, but we did put a 80MB SCSI drive in it
    Thanks for the trip down memory lane! Love your videos

      Ah, Nutshell. When I worked at LE in the mid-'90s, we were still using Nutshell internally to look up part numbers, figure out which models came with which options, and the like.

      My grandfather worked for a chemical company, and in the 80s they introduced payment plans to buy computers to increase computer literacy for their employees, my grandfather bought a Leading Edge Model D and a NEC Multispeed which I used for years, unfortunately I had a mishap with the NEC and some ROM chips and never got that machine working again, and the Leading Edge was donated, but the old machines just had a certain charm to them

    Great video! My first PC was a leading Edge 486 SX25, now long gone. After getting into the retro computer kick a few years ago I surfed eBay for a bit and was able to find two of them, as well as a 386, and Leading edge keyboard, VGA monitor, and mouse. One of these days I'll get around to cleaning them up...

I'll throw in any other XT stuff too just to fill up the box. And many thanks for the years of helpful info on how to keep these old machines running.

    Well, this takes me back. WARNING: LONG-WINDED MIDDLE-AGED REMINISCENCES AHEAD
    I worked in Leading Edge's warranty hardware support department in the mid-'90s, at the tail end of the Daewoo era. The Model D was long out of warranty by then, but it was still legendary within the company (albeit not quite as legendary as the Model M, which was downright mythical). Unfortunately, by the time I came along, manufacturing quality had taken a pretty substantial dip, so my colleagues and I were pretty busy. Just as one example, at the time LE sold a computer called the WInPro 486, which was notable for a) not shipping with enough RAM to run Windows, b) not being professional-grade in any way, and c) not really having a 486 in it (it was one of those stupid Cyrix processors that was really a 386SX with the 486 instruction set).
    Things picked up somewhat quality-wise toward the end of my time there, circa the summer of 1995--the last generation of Leading Edge PCs were pretty good--but the writing was on the wall by then. Leading Edge was getting its lunch eaten by other manufacturers, mostly with "Packard" in their names, and the product improvements came too late. I got out when Daewoo extended a hiring freeze to include not making up for attrition, causing the support department workload to spiral out of control. I remember one day we in Hardware Support all went to a big meeting with a Daewoo bigwig who'd come over to HQ in Westborough, and one of my coworkers asked if we could please at least hire to replace people who left, because we were really getting hammered. He stared at us while his young flunky translated, then scowled, pointed at us, and said without going through the flunky: "The rest... you work harder."
    FYI, since you note at the beginning that you didn't know whether Leading Edge ever made 486es: they did! And not just the Cyrix faux 486es, they had proper Intel ones in the last few generations (including a minitower very similar to the generic one you have there). In fact, when I bailed, the company had just started shipping its first (and probably last) Pentium model. That's another horror story, in fact; the computer itself was fine, but the Corporate Masters had decided to revamp the company's image, so they abandoned the triangle logo for something painfully generic and branded the Pentium line "Fortiva". This was at around the same time that IBM launched their "Aptiva" product line, and a brand of yogurt called "Activia" appeared on the market. So that went about as well as you would expect. By then I was on my way to the exciting world of supporting ISP infrastructure equipment instead of PCs, anyway.
    Finally, a fun fact: the last generation of Leading Edge laptops were made by Lenovo! That was before they bought the ThinkPad brand from IBM and started selling laptops themselves instead of being an anonymous OEM for other manufacturers. So they were actually quite good... not that that helped them sell very well.

    I was the Director of Purchasing for a company that was the largest distributor of Leading Edge computers back in the late 80's. We actually "owned" Leading Edge briefly, when they filed for bankruptcy around 1989, although later the bankruptcy court took the name away from us. Originally, Leading Edge sourced the products from Mitsubishi (hence the names Model M and MH) and then later, to lower costs (plus Mitsubishi tired of Michael Shane's tendency to pay late) and for better credit terms they sourced from Daewoo (hence the Model D, D2, etc.). Quite popular at the time, maybe even more popular than any one of the models was the Leading Edge Word Processor, which came bundled with each computer and was also sold separately. Daewoo sold us the remaining Leading Edge computers directly but wanted to market directly in the US under their own name after that, so we turned to Mitac computers (AKA American Mitac) as the 3rd suppliers for Leading Edge branded computers. But that sort of quantity and branding took time, and several months later the bankruptcy court took the LE name away so we rebadged them under our own name, and while they were actually quite nice, we never sold them in the numbers we sold Leading Edge computers under, since the dealer network had either collapsed or moved on to a more stable supplier. We survived, as it was just one piece of our business, but a lot of smaller dealers went under as Michael Shane (the original owner of Leading Edge) would often extract full payment or large deposits before shipping computers to dealers (often late). Shane's dicey business practice is kind of how we became such a large distributor - we didn't demand those terms and reliably shipped on time and still gave dealers 35% off retail in large quantities - and when Shane was up against the wall, he'd sell us huge quantities of machines for 50% off if we paid COD, which we could. Shane was almost operating a Ponzi scheme at some point, in my estimation.

    The first PC that I refurbished and sold for a small profit was a Leaning Edge 386 that ran Windows 3.1 in 1996/1997ish. I always thought leading edge was a local outfit building clones. Very cool to see this!

Great memories of that machine, I should poke around I may have some of the software yet.

Configuring cylinders and heads to get the HD to work and adjusting dip switches to get a sound card to not conflict with something else. This really brought back memories of those days. Very enjoyable and I'm even more curious about that second "multimedia" age PC since it is possibly right around the age of computer where I had to fight to get ethernet cards to work in an already crowded computer with very little resources remaining. A time when plug and play, was more plug and pray.

Could get it on the main AOL screen but functionality was all but non-existent. Don’t think I was able to access web pages.
