    Adventure games via Periscope Over the weekend I was having some fun with Periscope and having people join in while I played some old graphic text adventures. Remember graphic text adventures? They were text based adventure games but would show a picture above the text so you didn’t have to use your imagination as hard. You still have to type commands and read descriptions. Because of their slow pace I thought they would lend themselves well to a little bit of interaction while...

    My rev B IBM PC 5150 A couple of months ago I moved my IBM PC into the living room thinking that with a more prominent location I would use it more often. It’s fun to try out ancient software, or use the PC to connect to the occasional surviving BBS. I also like tinkering trying to use the PC to access the modern internet, or at least see if I can. I definitely won't be playing YouTube videos on it, but I can read reddit, or search Google. Because of the nice keyboard and no...

    A couple of months ago I purchased several relay boards and switching power supplies off eBay with the plan to re-use one of my original (256 megs of RAM and no mounting holes) Raspberry Pi model B computers as a sprinkler controller. The parts arrived and I set them aside expecting to have time to work on the project after the 4th of July. About two weeks before the 4th though I realized if I got the project assembled in time I could use the sprinkler controller as a fireworks controller. ...

  • Emulating an old HP-IB disk drive with HPDrive

    It'll never work like that! I bought a National Instruments AT-GPIB IEEE-488 ISA card last year intending to use it with HPDrive so that I could make an old PC pretend to be an HP-IB hard disk. I installed the HP-IB card in the old KT7A-RAID computer I’ve been using for doing lots of other retro things. Unfortunately the card had to go all the way at the end and the HP-IB connector was too large to fit on there which meant swapping the motherboard into a different case that...

  • How to Recover Data From Chrome's Cache

    Have you ever needed to pull an old web page out of the Chrome cache, and wondered how to do it? I had to do this recently myself. I was editing a comment on reddit, and for some reason it wasn't taking. After hitting reload I discovered to my horror that instead of editing the comment, reddit had replaced the entire text of my post with my edited comment! This was terrible because the post was very long and had been edited a few times. Trying to recreate it from memory would be...
