    Thanks for the reply! I've seen lots of reference to hard drives used by the Paintbox system, such as is seen in this video, but little with regards to floppy drives. Kinda strange that 8" drives...

    Very cool! :) Wonder if those were sold outside of Europe. I can't say I've seen any of them on this side of the pond, but I recently came across another embedded system which may be even more absurd...

    Quantel Paintbox 8" floppy drive

    Hello everyone. At a hamfest last month, I spotted a couple of 8" floppy disk drives in a pile of junk. One of them was in an external case, while the other was mounted to what appeared to be a 19"...

    Not all fluorescent lamps are created equal. Ones which use an old-fashioned magnetic ballast will likely strobe at the proper rate, while ones which use a newer-style electronic ballast might not....

    A few years ago, I went into Radio Shack looking for some NE-2s, and was surprised that they didn't carry any. However, they did carry 120VAC power indicators which used them or something similar,...

    I was just surprised it wasn't mentioned, since it's about the simplest solution. Sure, NE-2 bulbs aren't as easy to find as they once were (and NE-34s probably aren't even made anymore), but just...

    I briefly attempted to use my PowerBook 5300c on the 'net. Found an Asante (IIRC) ethernet PC card at a yard sale, installed the driver, and got it working. A vintage copy of Netscape Navigator was...

    A neon lamp powered by AC is an easier solution than rejiggering an LED to run on 60Hz, IMO. I've rigged up a pilot lamp like this one with a power cord, and it works well for stroboscopic rings on...

    According to the page ClassicHasClass linked to earlier, a HP 9000/715 can indeed run NeXTStep, along with HP-UX (of course), Linux, NetBSD, and OpenBSD. A HP Apollo desktop with the same class of...

    Yeah, I figured something like that might be going on, given that big heatsink in the front right corner of the board. How common were these upgrades, and what does it mean for the potential...

    Nothing. The connector was resting on top of a rectangular component labeled "2M2", and I couldn't see anywhere it would connect to. Directly below the "DOMAIN KYBD" port was a header with a jumper...

    Interesting stuff about NetBSD! I'll have to look into that if the HP-UX install proves to be unusable (and if the hardware is still stock). I've never used anything like this; closest would be the...

    Thanks for the reply! I was wondering why there are two keyboard ports on the back. Unfortunately, the included keyboard (with mouse attached) plugs into the "KYBD HP-HIL" port, so I'm guessing that...

    My first Unix machine: HP Apollo 400T

    Interesting! :) Thanks for the clarification. I figured it was something related but different, since the screen was of a different style, but you can never be entirely sure with the movies. Is the...

    Oddly, it appears that the Educator 64 came along after the PET 64, so they actually added to the costs of the later unit by keeping the SID chip and RF modulator, and adding the amplified speaker...

    According to this page, the main difference between the PET 64 and the Educator 64 was that the Educator 64 had a standard C=64 board and a built-in amplified speaker, while the PET 64 used a...

    I picked up a Mac 128k a couple of years ago which has a Sad Mac issue. According to the code, RAM chips at locations F6, F10, G8, and G10 have failed the "Mod3 test", whatever that means. Once I...
