Horace posted:These "Video Stabilisers" were sold in the back of magazines. Obviously only intended to stabilise and restore your picture quality, nothing else. I kinda love how the reflection on that label looks like 90s graphical dithering in a way. Still, I have a need for a 'stabilizer' circuit.

I've got some AV hardware in a box in my shed somewhere that I think is Marantz? It lets you boost video signals but I've no idea if it defeats Macrovision. I bought it 2nd hand in the early 90s. I'll dig it out and get a photo some time, in case it's interesting. e: A search of the shed revealed nothing, unfortunately. I did however find an 8-inch floppy disk, a linesmen's test handset and a Telecom Touchfone. I've no idea where that video thing went as I can't imagine anyone wanting to borrow it off me and not returning it. It must be here somewhere! Gromit has a new favorite as of 01:26 on May 8, 2022 |

Here's a macrovision suppression circuit from 1995 and here's one from 2006. They don't look too complicated.

But the A2000 has been down there for nearly 20 years and I just don't want to check the battery. Right now it's in a quantum state of maybe being ok, but I know if I look at it, it will be a horror show. Got some C64 games:

Even a person who collects normal ones might be tempted based on age and having the box etc., just as a curiosity. I don't know how common that kit is or was even in non-bootleg form when it was made or if they still make them etc. LIke I said you'd need to find a turbo-nerd. Hell, toss it up on SA-Mart, post about it in the modeling thread (I assume we have one) there's a good chance someone will want it.

RoastBeef posted:Here's a macrovision suppression circuit from 1995 and here's one from 2006. They don't look too complicated. It's not. Macrovision works by sending control codes to the automatic gain control. If the VCR is recording, those codes tell the AGC to go a bit nuts. Those codes are embedded in the lines used for interlacing information. You basically just need to strip out the codes.

Those codes are embedded in the lines used for interlacing information. You basically just need to strip out the codes. This is true, if by “sending control codes” you mean “cramming garbage data into the VCR’s recording-hole.” Macrovision usually screwed with the color/brightness of re-recorded content, by putting signals in the vertical blanking interval that basically said (while the electron beam was off) that the beam should be far brighter than should be possible. This made the auto gain control on most VCRs compensate and darken the signal for a few frames. Since the “brightness” of the colorstripe varied constantly, VCRs could never properly adjust. Some VCRs with manual gain knobs were mostly immune to this version, and would actually copy it right along with the rest of the tape. Later versions, especially on protection applied to DVDs (or sometimes added during playback by the DVD players themselves), put things that looked a little like vertical blanking signals into the horizontal blanking interval. I don’t have as good of an understanding how that one worked (other than it caused image tearing); neither did a lot of TV manufacturers, though, because it created problems for cheaper CRTs (even without a VCR in the signal path), and caused some strife during the very early DVD adoption period.

Apparently the real genius behind Macrovision was not the actual technique they used to implement the copy protection, but that they patented all the obvious ways to strip it from a video signal which gave them legal teeth to go after people making such devices in a pre-DMCA world.

Humphreys posted:Was it this thread where we were discussing some old timey food/drink youtube channels? The real problem with key lime pie is that the "key limes" you find at the market today (at least in the Americas) come from Mexico and Texas and are a shitload more bitter and drier and astringent than limes that were grown in the Keys, since they're grown in much dryer climates. Using regular non-Key limes is going to give you something much closer to Key lime pie as originally presented.

As I understand it, the modern ones are basically a database with a custom OS wrapped around it, but I have even less of an idea what the old ones were like. Honestly, all the custom IBM hardware and software is fascinating and weird to me - it's like a glimpse of a parallel universe that proudly predates and ignores the standards I'm used to.

That one might be more useful, but I prefer the open-ended nature of the Y2K sticker. Should have just turned the computers off and left them that way. At this point it's not a warning but a lament.

My Pentium 75MHz machine has a Y2K bugged BIOS, but it only affects the clock. If you set the time in BIOS to anything past 2000 it resets to 1.1.1995 (the year the motherboard was released and earliest date it allows). You'd think five years was close enough to test it, but no. This lead me to write a year prompt to my autoexec.bat. Initially I just ran the date command but I hated typing the whole date. So now I keep the BIOS at the correct date, except in the 90s and only enter the correct year.
