[Photos] Vintage LGI

I bought a vintage 286 manufactured by LGI... This thing is running without any problems! It comes with nice dye sublimed caps and vintage Blacks. These are my first vintage Blacks and guess what I think about them now... :shock: :shock: :shock: :mrgreen:

Great computer, but I hope you didn't buy this keyboard for just the switches and the caps! At least put in some other cherry switches you don't care about back in there!

Are you sure that the caps are dye sublimed pbt? This shape of caps always reminds me of pad printed abs. If these caps are pbt it's a swett find, this board has a pretty nice legend and font which looks pretty.

If you zoom in the edges are a bit blurry, indicative of dye sub.

I'm sure that these caps are dye sublimed pbt... :o

And no, I did not bought the system for harvesting switches and caps... :shock: First I wanted to build a Unix-Console with a Raspberry Pi but then I've seen that the system was "fully loaded" with games and apps... :D

The ink on the 2 is raised, while it is flat on that asterisk sublegend. I'm not sure what these are.

Solenoid: ON!
I tried to focus on a legend - I think they are flat. I can't sense the letter even with my nails...

If you have some acetone handy you can try applying a small amount to the inside of a keycap, if it is ABS it will dissolve. I would be surprised if these are actually dyesub PBT

all you would need to do is to zoom up even on that 2 keycap. the texture of the cap does not change when it gets to the 2 therefore how can it be printed?

It is like playing Sherlock Holmes for me... :)

Lucky me I can provide some comparison shots. I'm 100% sure that these are at least PBT and not ABS.

Dye sub PBT -- ? PBT -- Double Shot ABS -- Pad printed

The questionable caps had "BTC" inside, maybe this helps a bit?

how can you be sure it's PBT ?

I've said it now multiple times but as far as I can see this is clearly pad printed ABS ...

and even then, you can clearly see what it is in this pic :

I'm still not sure why you still say this but they're not bad IMO, okay the lasering might not be to everyone's liking but they're certainly not shit ... they're cheap and thick. what else do you need ?

Oh, I thought those looked like BTC caps.
You can test for ABS with acetone. Wet the tip of a q-tip with acetone and rub it on an area on the inside of a keycap. If it smears, it is ABS.

When I paint on top of another layer of paint, the brush strokes from the first layer come through.

Yeah after the second image with the 2, I'm thinking it's some kind of printing as well, though it may not be pad print.

It is a very good quality, the printing is crisp sharp. Meanwhile I found the manufacturer BTC in the wiki but without any information how they manufacture their caps...

Crisp sharp edges literally exclude dye subs because dye sublimation, as explained in the wiki,
is different to printing in that printing forms a layer of paint on top of the plastic, whereas dye sublimation causes the dye to sink into the plastic.

I am not sure I have ever seen branding on (well, inside) a keycap before!

I was looking at the keycaps and noticing that the typeface is a lot like Key Tronics, which seemed an odd company to make a keyboard with Cherry switches. However, being BTC makes sense, as BTC used the same typeface as Key Tronic for a while (albeit normally as double-shot).
