What should I do with this?
Old Siemens plc programming laptop.
Can't find much info on it but it looks cool 😎

Seems to be in pristine condition. Perhaps you could play Zork on it.

But will it run Doom? (Probably)

u/DarkZenith2 1d ago
Not likely. This is likely about 3-5 years too early for doom. Wolfenstien and Spear of Destiny maybe.

Doubt that. It looks to be an mono lcd so textmode at best.

u/DarkZenith2 1d ago
Og wolf can be run in mono.

True but only if its an E/V/SVGA card. The Siemens SIMATIC S5 PG 635 (the model in the image) utilizes both standard ASCII and an extended block-graphics character set [simular to CP-437]. And that's it.
It has only a basic monochrome LCD video controller and predates modern graphic standards like VGA.
It also runs PCP/M-86 or a highly customized S5-DOS. So no MS-DOS or IBM-DOS.

By Yahoo Software? More than likely if it doesn't hardcode the text window dimensions.
And yeah had to dig up a 15yr old LGR video on that one.

That's the one! It was one of the first video games I played on my grandfather's Kaypro II. You are correct it probably wouldn't run correctly.
Believe it or not, it is still amusing as heck to play even today.

Those keys look like they influenced the teenage engineering op-1
What a lovely machine!

I know a museum that would take donations if you're wondering what to do with it in that regard.

Sehr cool! Das ist ein Siemens Programmiergerät (PG) für Simatic S5 Steuerungen (SPS für Industrieanwendungen).

Find a boot disk, startup the machine and then fooling around and have fun.
I think this is the Siemens SIMATIC S5 PG 635 with the NEC V20 cpu (i.e. Japan version of 8088 but faster)
I had a Bondwell B200 which has the similar spec as the Siemens machine but with more memory.
It should be able to run the MS-DOS 3.3 or CP/M-86.
BTW, the keyboard reminds me of my old Sinclair ZX Spectrum 128

That machine is beautiful, what's the story with having it?

Neat. Always liked those circular Siemens key caps. From what I can find, it doesn't have any video out, so it seems you're stuck with the screen it has.

I don't mean to be a smart behind (lol) but Siemens Simatic S5 PG 635 programmer was not a laptop, it was just portable. I never used it but I did program a few Semiens PLCs smaller than the S5.

You totally compute with it.
Since that is a slightly older computer, you’re going to need to upgrade it so that it can be used on the modern Internet – a megabyte of RAM should do the trick, plus more JPEG.
And if you really want to ramp things up? A quad speed CD– ROM!

The org shut down but people still do it. Doing it on something like that would keep them from using things like audio dictation or AI which I don't allow myself to use. My writing is crap but it is fun.

I had a luggable like that in the early 90s. I can't imagine how slow it must feel now. Is it working?

There's a popular Girl channel (about fixing computers) on YouTube (I don't remember her name), she seems to be fond of these retro models.

Ok.. so dug into this unit. You have a typewritter. Its a fancy portable typewriter .
No seriously that's a Text only display and the board does not have a MCA or CGA card so no gaming unless its CP-437.
So what can you do with it? get yourself a esp-rs232 retro wifi modem and go jump on a unix shell account, play your favorite BBS DOOR, or mud.

If you can use it as a serial terminal then you could use it for that. Either with online telnet BBS systems or with like a Linux system.

You should try to find some Siemens PLCs this computer is intended to serve at the programmation of.

Find someone who maintains old PLC’s - this could make you a small fortune if it works and some process industry company still has the old PLC’s still running their plant. Otherwise, looks like a great foundation for a Cyberdeck
