Sell it, or give it away to this guy. I worked with plenty of this junk as a kid, it is perplexing to me why anybody want to collect it, but I am an engineer - we build better stuff today. I think you're going to be disappointed. It belongs on a museum, and I don't think it's useful for anything when you can simulate it at the gate level today - and you probably won't even do that ever.

@@leandrotami I didn't mean to sound critical, I just don't understand why people collect this stuff. If I want to relive an experience from my childhood with a computer, it's the experience of using the machine, and simulation is 100% accurate with the machines I used. I would never own a C=64 again simply because compared to the machine I have today, it's a waste of electricity to even turn it on. My VASTLY more powerful computer can simulate 20 of them running at the same time on 1 machine, and use less power. But it's fine if you use actual hardware, of course. I just don't understand it.

Looking forward to the Part 2! I actually went through about this same adventure with my Compaq Portable. It turns out that the power supply is smart and if too much current is drawn, it will shut down to prevent damage. Those darn tantalum's are a huge problem in electronics this age. I ended up having one of them on the motherboard and one on the video card that were shorted. Found them by pulling the motherboard and testing the power rails using a bench power supply. Turn it on briefly and use a thermal camera to look for hot spots which show up pretty fast. Pull and replace the cap and fixed! I think my floppy controller had a bad can oscillator on it too which seemed like an odd failure, but was also easily to replace. The AC filter smoked not long after playing with it and was to be expected according to many who were giving me advice. This got it booting, both floppy drives worked great right off the bad. Keyboard problems were the next thing I found with the bad foams - replaced those. The last problem was that some video characters would inadvertently change on occasion. Used a Hakko FR300 to remove DRAM's from the memory board and replaced them and solved that. These things can be quite a bit of work to get working, but they are really cool machines. I think you can use a ctrl-alt combination to switch between a true mono mode and cga mode. Maybe ctrl-alt-< and ctrl-alt-> or something like that.

Yeah, BBS - Bulletin Board system is very much like a web page but run by one person or company and you connect to it by dialling a specific phone number. I used some around 1993 and 1994 (downloaded shareware games from them mostly), right when the internet was starting, but the internet very quickly made them obsolete. Though... You could still find a decent number of them up into 1998 or so... And even to this day there are still a few random holdouts. The thing about a BBS is that anyone with a computer, a few modems and a few phone lines could technically set one up. Nowadays I suppose even phone lines themselves are becoming borderline obsolete technology though. So I suspect BBS will die a final death whenever fixed line phones do.

Wow, does that bring back memories. Through my late father, my sister and I gained exposure to a variety of computers in the late 70s/early-mid 80s, more so than many of our peers. Dad was a Financial Manager in Forestry R&D for Weyerhaesuer, and not only did we get to interact with the DEC VAX mainframes in the basement with the communal Courier terminals just a few yards from his office, but he regularly brought home computers on extended loan. They were primarily intended for him to deal with his work projects, but we used them on our own school reports in grade school/Junior High, at a time when practically every other student was writing in longhand or with a typewriter. My first encounter with a "portable" computer was a Compaq Series I like this, complete with a HP Thinkjet thermal printer. Later on, we had an IBM PC XT and PC AT, as well as a Compaq II portable, all on loan from Weyerhaeuser. Dad didn't personally buy our first computer (a Compaq Deskpro 386 Desktop) until sometime around spring 1990. I remember the Compaq portables we had on loan had a fancy travelling case that stored the computer, the printer, had space for software boxes, and paper, and even had a small luggage cart...a far cry from what we have now, with phones far more capable than any of that.

My dad had a version of this that came with an amber monochrome display (I don't think it was a Compaq but the form factor was almost exactly the same). One of the greatest joys was getting old DOS programs like JET and Starflight to work properly, let alone being able to play them. I still fire up a copy of Starflight on a DOS emulator every now and then just for kicks. Formative years and all that. Great video, wish we still had that old machine kicking around but I'm afraid it was long ago consigned to the waste bin. Thanks :)

It's not entirely correct to refer to the Compaq video cards as "CGA", as although they are CGA-compatible, they also offer a high-res 640x350 text mode on the Portable's built-in CRT, giving it much sharper text characters than CGA's 640x200 resolution. Later revisions of the Compaq video card added 640x350 graphics to the built-in CRT, giving it EGA compatibility. p.s. I've heard that early revisions of the Compaq Portable's motherboard have a pinout for a cassette port, although it was never populated or supported.

Looks like that capacitor was shorting the rail to ground and the power supply was shutting off to protect itself, it's really common for tantalum capacitors to fail Short Circuit. (Edit: I feel like I should mention to clarify electrolytic capacitors usually fail open circuit or simply loose capacitance, whereas tantalums usually fail Short Circuit.) I find it kind of funny that the modern power supply you plugged in lacked the protection features of the built-in older one. Hope you didn't chuck the original board out as these are fairly rare and it's likely an easy fix.

Similar thing happened to me on a 286 Octek board. One tantalum blew his head off upon first power up. The failure mode on these is spectacular. The PSU was definitely going into self protect mode when the tantalum shorted out. I was lucky in that I did not have any burnt traces on the board, but the risk is always high. The guy who worked on memtest86 for a long time is designing a smart ATX2AT converter (x86.fr/atx2at-smart-converter/) which can protect mainboards from those kinds of failures by shutting off all power when detecting an unexpected surge in current.

WOW - have you brought back some vague memories for me! I remember first seeing this "portable" in a high-end computer store in San Antonio called Abacus back in... oh hell, probably 1985 or so (they were excited to sell the Apple IIe with dual 5.25" floppies and the the Apple IIc). I loved the Compaq and wanted one so bad even though at that time the base price hovered around $2K or so. What memories... Thanks so very much for taking me back to when PC Jocks did component level testing instead of just replacing a board. Definitely Subscribing!

No need for tools to open the covers. Just lay it flat, and push the plastic cover down in line with the logo. It will pop open on the top by itself. Saving the clips, and no tool damage. BTW, these computers work great off a Hercules Graphics card. Also, this model came with 2 floppy disk drives.The Plus model (with a gold logo) came with a Seagate MFM hard drive installed - 10MB.

I remember when these "luggable" PCs first came out; being heralded as a portable PC, with the connotation of Compaq being a "compact" PC. In later years Compaq went to producing decent quality desktop PCs. I have one those boat-anchors in my garage, where its weight and heft does well to anchor, in place, some stiff cabling on the floor in my garage.

5:53 The magic smoke escaped! Oh, tantalum capacitors, almost always the culprits! Those are the worst! Now that I think about it, I have a netbook that doesn't want to power on. If I discharge the capacitors and plug it, it turns on and back off in just about 2 seconds. Maybe a shorted tantalum capacitor? I suspect the CPU, though, as there were some problems with the (integrated) graphics.

Ha, have fun restoring the foam and foil board! To be honest, it's something I've always wanted to try, even though that kind of keyswitch is widely disliked. From memory, I believe it was some sort of model railroading foam that some Apple Lisa restorers found to work best. Something like a sheet of foam used to create the rail bed or something along those lines. Anyways, keep up the great work!
