      So, I learned that early Macs had an onboard reset that was inaccessible unless you bought a special plastic insert – Programmer’s Key – then you could press it “from the outside.” Were there any other computers with that idea? User-added break/reset? https://en.wikipedia.org/wiki/Programmer%27s_key …pic.twitter.com/eWXAOFst8r

      Not quite the same but the BBC Micro had a screw you could turn to physically prevent the BREAK key (software reset) from being pressed down.

      (Were you a teacher in that scenario? Is it similar to the kiosk mode on the iPad?)

      Matt, I’m losing my mind! Here’s a photo of it enabled. I was literally right next to this computer a month ago, and passed right by it!!! https://www.flickr.com/photos/anachrocomputer/8271450235/in/photolist-dAVkYX-dAVm3F-eZ9HYM-dK52hk-nsimLw-nJMHz8-8bBg9K-9GE8mz-6i9sNk-8Burs5-9GGZXJ-btriaC-76z9f9-6YgaFe-btri81-bd3udR-5242ah-bdcN4F-nfiLZz-GaVm5-8qszwe-9GE8tg-5y3Frt-551dXe-dJbEYv-dA1Xrd-btbvUE-8bGEwh-6sU5vB-21E2GNK-6rQFzD-63iitb-63e3he-dZmCjh-nfiGym-6idHiJ-3v8FBg-7XU2Y1-33MP8K-2cSXUi-4ZkUoD-296kTaR-aEnj9u-4cpqSE-9gXSei-fjmE1-LZEcr1-8c8qJe-4Ci6dn-fjmDZ …

      There is something kind of amazing in the fact that Apple II had the same problem, and they just started using slightly stronger springs – and eventually required Ctrl or something.

          …while the BBC/Acorn people *moved the key* and installed a special screw to prevent it from being pressed. Kind of like Reverse Shift Lock or something! I can’t believe this exists.
