TI-99/4A

I looked on the wiki, the the topic of Texas Instruments is sadly only a stub. Can someone please tell me what switches these are? The caps are black and white double shots.

Sorry for the poor camera shot!

These look like a variant of Stackpole switches. They are linear.

Thank you, Xmit! I have 4 of these; 2 are complete, and this one has no caps. There is one more that is missing some caps. They will probably go the the classic collectors group, since I doubt they are wanted here.

Edit: There is a much better picture here: https://www.flickr.com/photos/48395504@N00/9279202197

Did you have more photo about the keyboard ? This green variant is rare to see.

I can take more pictures in a week or 2. Right now that particular one is still in Dallas.

Stackpole switch grid. A copy of old Hi-Teks. Texas Instruments used them pretty often. Don't think I've ever seen green ones before though =o . The wiki definitely needs more TI stuff .

Agreed. There are tons of undocumented TI Alps boards out there. SKCL Green, Brown and SKCM Brown I've seen on TI boards!

I thought that “Stackpole” and “Hi-Tek” switches were the same company.

Nope, but Stackpole nicked Hi-Tek's work. They got sued for it but they won iirc.
