I wanted to connect external keyboard to my 30-year old Toshiba T3200SXC, and this is what I see. Would you break it, or not? 😉

Depends. If it's an item I just wanted to collect for historical or other reasons then no, I wouldn't break it.
If it's an item I actually want to use because I enjoy using it I would definitely break it, if that lead to more enjoyment.

the first question to answer would be... is there even a connector behind it? ^^

If there is a connector, AND you are going to use the external keyboard a lot, then it would be ok to break out the cover I guess. Then again, why would it be there covering a useful connector?

If there is no connector but you've got the skills to solder one (and everything that may be needed to get it to work), it's just a great little adventure to get it to work 😀

If this ones is already modified a lot (ram upgrade, CF/SSD, hotel), it may be ok, since it's already been tugged into the 21st century.

If you're not going to use the the laptop much, or at least the external connector, and the existing keyboard works fine... I'd skip it. That would keep its original condition (and value).
On the other hand I don't think it would lose much value on this... It's not like you're going to put a Ryzen and 2080 in that would not be worth a single penny in 10 years from now 😉

Looking at my IBM model 30 systems: one is mint, even with all the ISA slots having their plastic caps (also breakable) and another has them removed, to add VGA and play around with other cards. No regrets as it's just a machine for fun.

the manufacturer would have punched it out themselves if there was a connector there, it was probably an optional feature

(unless of course it was a just a QC failure or something)

a quick google search led me to a page advising to remove the plastic if you want to connect an external keyboard, and lists the T3200SXC... though I couldn't find if this was definitely true for all of them, so before cutting anything out I would definitely check.

Can you safely disassemble the computer to verify the connector is installed? That's the first thing I would try before cutting it up. If possible, I would test the keyboard port with the case off, though I doubt Toshiba would have gone through the trouble of populating a non-functioning connector.

Thanks for the answers, yes, there is a connector (photo attached), maybe I should stated that in the post 😀

I did a lot of modifications but only internally. Installed DIP RAM sockets, speakers, new battery, new industrial LCD panel with 18 to 9 bit signal converter so it works with that motherboard, redesigned the power supply (replaced the internal AC/DC board with custom DC to DC circuit; every capacitor in old PSU leaked and entire PCB was black).
But the the only modification I did to the external enclosure so far, was removing 230V AC connector and replacing it with 3d printed DC jack adapter plate (attached photo). Everything else is indistinguishable from the original.

I will probably not poke the hole at the moment, but maybe this thread should be an "ethical/moral" debate - should vintage hardware be treated with special care or not, what is allowed and what shouldn't be, are the internals or externals more important, when an antique stops to be an antique, am I the owner of the machine or is it cultural heritage 😉

But if I poke the hole - should I keep the plastic piece or throw it away, should I glue it to the case later etc., all of there are open questions, maybe you have similar thoughts when working with another hardware 😀

you could build a thin custom connector (looks like there is a sliver of space between the plastic shell and the connector and route the cable to the back onto your 3D printed panel and add a keyboard connector on there.

if there is a DIN back there that is just arbitrarily blocked by that stupid plastic I would not hesitate to remove the plastic

because it is just stupid, and should have never been there

They way I see it there is nothing wrong removing a plastic cover that could have been removed the first day this pc was bought. I mean it doesn't change anything about the PC's authenticity, unless it was some new-in-box item, then yes it does make a difference.

This is some really nice work. I think the coolest modifications/upgrades are the ones that are completely stealth. If you ever get tired of having an external AC/DC power brick, you might have enough room in there for something like a meanwell LRS series power supply. I'm using one to power a picoPSU in a mini 486 build, and it works really well.

To me, the keyboard connector blank seems like a feature of the original product, so removing it doesn't seem so much like a modification. I would have no qualms with removing the blank and throwing it out. This is fundamentally different from cutting a new hole to mount a new connector, or this abomination.
...On the other hand, if the computer was being preserved mainly for its historical significance, like a museum piece, then it would probably be better to keep the blank intact. Or, at least keep it with the machine after removal to document this weird 'feature.'

"Just get rid of the plasma display!"

I bet that guy hackjobbed a nice vintage mechanical keyboard into a USB one too, or pillaged one for its keycaps and threw the rest in the trash.

Yeah, that page ruined my day. Apparently he tried and failed, so threw the original out and installed a modern mechanical keyboard.

I hope the original was broken beyond repair to begin with, or at least that's what I will tell myself . 😢

Well, I already have a hole in ISA bracket because I desoldered BNC connector from network card (the plastic door wouldn't close with it), so I could try to put PS/2 connector there 😀

I'm at the point where I would rather not punch out sheet metal drive ports; but I might just be losing it. I think keeping it original is sweet.

As for your laptop, I'm not sure that is the same thing. I don't know.
