Checked to see if my grandpas old IBM PS1 still worked

Was IBM DOS different from MS DOS? I can’t remember.

161 and 163 are cmos error and while usually does not really matter in a PS1 these errors cause the floppy drive to do not work... so if you tried any floppy disk unsuccesfully it is not an issue with the drive but simply the cmos battery

I miss my IBM PS1 even though it’s impossible to upgrade it was one of most iconic computers I’ve ever owed

Should be able to play DOOM.

Doom8088 is a port of Doom for 16-bit PCs based on GBADoom. Right now, it's only a proof of concept. It supports only Doom 1 Episode 1. There's no support for sound, music, multiplayer, mouse or PWADs. Demos are out of sync and there are lots of crashes due to memory issues. To decrease memory usage, only one texture is used for every wall.

GBADoom needs only 256 kB of RAM. A PC can have 640 kB of RAM. That's more than enough to run Doom, right? Well, in contrast to a Game Boy Advance, on a PC the code, graphics and level data all use that 640 kB. To make it fit, for every rendered frame, every image is loaded from the hard disk into memory and after it is used, it is immediately freed to make room for the next image. The lookup tables for sine, cosine etc. are stored on disk, so for every calculation a file on the hard disk is read. (Maybe using a RAM drive could speed this up?)

RealDOOM runs it too.

Seeing things like this has the ability to take us right back to the moment where we built those memories.

I had a PS/2, and I still remember what the tactile feel of pushing the floppy eject button. The sounds of the PC speaker POSTing, and those codes telling you to replace the CMOS battery and plug a keyboard in 😁😉

PS/2 was so annoying for software compatibility/upgrade cost, but there's no question it was quality hardware. Love that kerchunk.

We've seen the birth and eviction of home computing, and it's been a memorable journey!

Yeap. One of my teachers got one of these and I remember thinking how slim and modern the case looked compared to the already-ancient IIc in another classroom that I was learning BASIC on (and had previously thought looked slim and modern compared with the OG Apple II next to it).

Yes thats true 😃

So many nightmares of people sending resumes to my employer saved in Works format, which naturally wouldn’t open in Word.

[-]

et-pengvin@reddit

Obviously there are issues with both docx and odt but I'm grateful that open formats are so much more common now.

chandleya@reddit

It was less about being open and more about Microsoft being dicks. You could save Works as Doc or Xls, you just had to have the wits to choose to

Looking great! If you replace the CMOS battery, you should be able to get rid of the 161 and 163 errors during POST. If you don’t plan to replace the battery (yet), at least remove it.

(Error 301 is no keyboard; I imagine you just didn’t have it plugged in at that time.)

[-]

chandleya@reddit

Seriously, take it apart today and remove the CMOS battery! They fail and kill the whole machine

[-]

AllishComedy@reddit (OP)

My cousin said he was able to play a few rounds of overkill on it so I don’t think it’s having any errors

[-]

TomRx@reddit

301, 161, 163 are errors on the press F1 to continue screen. The WordPress link is really good. I used it to restore my PS1

https://ps1stuff.wordpress.com/ has lots of great info for helping reconfigure it.

This, or a similar model, was my first computer. 286/1MB RAM/30 or 10MB hard drive, 2400 baud modem, and later the IBM sound card. There's an emulator for it as well, including the "quad gui" thing:

Forgot all about the PS/1. Memory unlocked.

Oh man… seeing that first screen brought me right back in time. I miss when computers were this ‘simple’.

[-]

thomedes@reddit

Why wouldn't it? It's a true IBM from an epoch wbere they still did things properly.

[-]

ShyGal_Lilly@reddit

What monitor is that?

[-]

AllishComedy@reddit (OP)

The one that came with it? 🤷‍♂️

They were from 1990-1994, which was only 30 years ago. I had PCs before then, and I'm a way off being a grandpa.
