IBM PC AT: 1988 Upgrade Special! 640K RAM, Adlib etc

This new old stock IBM 5170 computer has just been unboxed. Now it's time to upgrade like it's 1988! 128K+512K RAM, 8MHz Intel 80287, 1.44MB 3.5" disk drive, and an original Adlib sound card.

● Here's where I first set up this brand new IBM:

Wow, there's a lot of $P$G requests in the comments. HERE YA GO :P

Watching 30 year old hardware work is strangely interesting.

Over 1mb of ram. Madness, no one man was meant to have such power at his fingertips.

I always find it funny when people input the current date on really old tech. It's like you are waking it up from a long cryosleep and it's confused as to what year it is.

I have seen Autocad run on an IBM 4.77Mhz 8088. You could see curves being plotted point by point.
Then an 8087 was added and what a difference did that make.

I could never relate to anyone that has disliked this video. I was transfixed the ENTIRE time. I love old tech, I love old computers, and I love setting things like this up. I just lived a wonderful adventure through this video. Thank you. Reminds me so much of working on my first Tandy 2500 sx/20.

All I can say is thank you for bringing this back to me.
This was the first PC I ever used at my grandfather's house at 8 years old.
He never used it, but this kickstarted my computer craze that has lasted a lifetime.

No one needs so much ram...he is showing off.

[nickloss]

the size of that 128k memory upgrade card is hilarious!

[DarkTenka]

Jesus its like watching through a portal 30 years into the past.

Me: "hey, you can 3d print those rails!"
LGR: cuts a piece of plastic and drills holes in it
Me: "O-okay, this works too."

[kingneutron]

0d00d, you fixed *everything* you wanted to do on that box. Even homemade DIY floppy rails?! YOU ARE THE MAN!!!

I really like this type of content. It's good to know they still are big YouTubers doing something different.

[newtekie]

I love these more technical "struggle" videos. It really shows the work that goes in to keeping these old systems that we love going!

[windwalkerrangerdm]

Once every couple months I feel like I have to tell you that I admire what you do. All my childhood was just like this video, trying to upgrade and install softwares to my old 286. In the end I had a 40 MB drive 4 mb ram 4x cd rom 486 dx 44. I liked it because everything was 4. I feel just the right kind of itching nostalgia watching you. Congrats.

It really is amazing how far computers have come, while it's also amazing seeing how little has actually changed behind the scenes.

The 512K RAM card doesn't backfill the conventional memory to 640K because when IBM designed the AT, they thought everyone would be using protected-mode operating systems, in which case it's more useful for the additional memory to all go into extended RAM, rather than conventional RAM.

But the long-promised multitasking DOS never materialized and everyone kept on using regular DOS, so IBM offered the separate 128K card to increase the conventional RAM to 640K. Aftermarket companies introduced AT RAM cards that would "auto-backfill" so with them you wouldn't need the 128K card.

This is the computer that started me on a lifelong love of computers. In 1988 I was 20 :) My friend's dad had this very computer. When he wasn't home, my friend and I would play with the computer. We learned Dos on this computer. Kids these days don't even know what Dos is! Thanks for sharing this. It took me back to my younger days and made me smile.

Oh, thank you for the tip about gsetup! I gave up trying to get the 3.5" side of my TEAC 505 with all of the various versions of the IBM Diagnostics. I was half a step away from replacing the BIOS with a set of aftermarket AMI BIOS ROMs to try to get around this issue.
