CGA says...
This month actually marks the IBM 5160's 35th birthday, so why not show off my working (and pretty much complete) specimen. This is one of the later models: half-height floppy drive + ST-225 hard drive, 640K motherboard (fully populated), last BIOS revision (05/86). The latest date code on the chips is 8649, so this machine was made shortly before the XT was discontinued altogether.
I received this from Trixter, truly a gentleman and a scholar, along with a separate box of stuff to round it out: an IBM PC/XT keyboard, a joystick, some software/games (including a boxed IBM PC-DOS 3.30), and the Guide to Operations. The machine itself is very well-equipped too, complete with an XT-CF adapter, an IBM CGA board, and a Sound Blaster Pro 2.0, but more about that in a bit.
This thing went through a bit of a misadventure en-route to me. USPS turned out to have some inexplicable restrictions on package sizes to my country - except for Global Priority Express shipments... and I don't need to tell you how much that would've cost. The only available box that satisfied these arbitrary limits didn't leave much room for extra protective padding on the sides. After some consideration, we decided to brave it anyway: those early IBMs are built like brick shithouses and could stand being knocked around a bit, right? So, off it went on its merry way with as much compressed foam as could be stuffed around the sides and corners.
My first clue that something was wrong came when I picked up the package from the post office, and heard the ominous yet unmistakable sounds of something rattling inside... uh oh. Opening it up, it was immediately evident that we had underestimated our respective postal services' capacity for malicious damage.
In case these photos do not convey the full magnitude of the crime: something, somehow, has managed to apply such a massive amount of force to this box that the corners of the cover were savagely bent inwards at the back, on both sides. Remember, we're talking heavy-gauge sheet metal. This initially prevented me from even removing the cover at all, until I employed a screwdriver and a hammer rather forcefully (the thought still makes me wince a little).
The cover yielded, and it transpired that the rattling I'd heard was only the PC speaker, which had been knocked out of its holder; that was the least of my problems. The back panel (also metal) evidently got a vicious whack on its right side, just where the card brackets go. This shoved everything forward, also slamming the full-length CGA board against the front of the case and dislodging the little plastic brace that keeps it in place there. The hard drive bay cover wasn't spared either; one of the lobes where it's screwed to the chassis was broken off.
None of the important components appeared to be busted or injured, but this naturally left me a bit dispirited, fearing damage to the cards, the slots and/or the motherboard... let alone the bits I couldn't inspect at a glance, like the mechanical innards of the floppy drive. However, testing was gonna have to wait, since I was going away for a couple of weeks and didn't yet have a 220V→110V step-down transformer (the PSU is American).
Imagine my considerable delight when I came back, got the power converter, plugged everything in, and gingery flipped the Big Red Switch... then the RAM test crawled its way up the count, to finally greet me with this heart-warming display:
Rock 'n' roll! Yep, it Just Worked. Actually, everything just worked; the CF card was helpfully packed with diagnostic programs, music/graphics stuff and so on, so I soon established that there were no casualties except the aesthetics: from the sound card to the floppy drive, all systems are go.
See, those early IBMs were sturdy steel beasts and for that I am thankful. I'm not sure how they managed to inflict such next level punishment on the package, but they must've tried real hard to brutalize it like that. If this was any kind of plastic-cased computer (or monitor), I'd be fishing jigsaw puzzle pieces out of that box. But even with a few nicks in its armor, the IBM XT is a die-hard heavy metal warrior.
Now that things were looking good, I took out the cards, applied more physical persuasion where needed, and soon the case and cover were looking much better.
