This right here is a machine from 1987: the IBM Personal

And as you can see it has seen better days.

I got this pretty cheap on eBay a while back.

It's just not in great shape, it needs a good bit of work.

But that's okay, I was just happy to get one of these early models of a Personal System/2.

They had the Model 60 and 80 and stuff like that.

I have those but I did not have one of the quote unquote “cheap” ones that IBM was

So I thought this would do nicely for an upcoming video that I have planned on the Personal

System/2 line and as is obvious it's covered in all sorts of grime

And somebody even scratched out the little sticker on the front here that would normally

show like the serial number and the precise model number and everything.

I don't know what this thing went through but I found it sad.

And this power switch is not doing what it's supposed to either, it's just kind of flopping around.

There's no give in it whatsoever, so that's gonna need to be fixed and then

there's this empty bay in the front here which, depending on the model of Model 30 that you

got from IBM, would have had either a second floppy disk drive or it would be filled up

with a 20 or 30 megabyte hard disk drive.

And that is what this one originally had because the model number exactly that IBM referred

to this was the 8530-021, meaning that it came with the hard disk.

It also has some sort of networking card installed around back.

Not really sure what that is exactly yet but I suppose we'll see inside and perhaps that'll

be a clue as to what this did in a past life.

Getting inside the Model 30 is pretty simple, all you need is a Torx head screwdriver with

And there are four of these screws around the edges of the case.

Then once they’re undone they actually don't come out of the case, which is kind of nice,

They just sort of dangle in there and they're spring-loaded,

And then the top of the case just slides off here, and yes: this is all plastic.

The bottom of the chassis is metal but yeah, this is one of the cost-saving measures that

IBM went to for these models of Personal System/2s.

Speaking of cost-saving measures, I assume: here's that power switch and as you can see

there's just a metal rod that goes between the power switch on the front of the case

and this toggle on the power supply itself.

It looks like that just sort of popped out of there at some point so whatever man.

All you gotta do is pop it back in place and it works just fine!

Not the most robust power toggle I've ever seen

but hey, at least the rod is metal and not plastic.

All right over in the drive bay here we have the double-sided double density three and

a half inch floppy disk drive over here, it's a Mitsubishi model.

And then on the right we have the other side of the floppy disk cable just in case we want

But we don't, we're gonna be putting a hard disk if all goes well.

And unlike many earlier IBM personal computers the 8530 has a hard disk controller built

That's not any of the usual suspects like SCSI, IDE, or even MFM.

A bunch of PS/2 machines used something called ESDI or Enhanced Small Disk Interface, which

looking online it seemed that's what this came with.

Not only is it a little strange in that regard but there are no power cables coming from

the power supply to plug into a hard drive, assuming I could find the right one.

On this machine the power actually goes through the connector on the hard disk or floppy disk

controller through the cable directly into the drive.

So there is no separate power cable, meaning that if I do put a hard disk in here It's

going to have to be one that is compatible with this and I'm gonna have to find the correct cable.

Anyway right here on the board you can see the CPU,

it's an Intel 8086-2 on this original Model 30.

There's also a later one with a 286 installed.

And this blank socket right here is for the optional math coprocessor, the 8087, which

Over towards the middle of the motherboard you'll see this riser card.

And this provides the expandability options for this machine,

which comes in the form of three ISA slots.

And it also has a battery on the riser as well, I was not expecting

Most of what I read online said that these normally came with like a Dallas real time

clock chip but this came with one of these barrel batteries.

And yeah, you know, I don't like keeping these things around but we're gonna see if it works first.

And then here is that gigantic networking card.

This was not standard to the machine, whoever had this or -- whatever company used this

We'll find out what it is a little bit later.

But enough looking around, let's go ahead and get to some cleaning!

Starting with a little compressed air and tossing these dust bunnies out of the way.

And I'm not gonna give this an *extremely* deep cleaning because really, I have a lot

of Personal System/2 units that I want to show in an upcoming video and I just kind

of want to get this one in a presentable shape and feeling nice and clean, relatively speaking.

I'm just going over everything with an assortment of anti-static brushes and getting all this

stuff kind of cleaned up and feeling decent.

Because really, other than the caked-on dust it's not in bad shape.

I was really hoping there were no weird leakages or rust bits or yeah you know, who knows.

There's all sorts of junk that can go wrong on these older computers depending on how

they've been stored and for how long and where.

But all things considered I mean, it's mostly the outside that looked really bad,

Alright I'm curious about this other half of the board and this gigantic networking

card is in the way so we'll get that out of there.

There is a lot more dust over here, that's for sure.

Oh well, nothing a bit of brushing and some time can't help.

And gonna go ahead and take out the RAM sticks here.
