    Sound card recommendations

    We used ESS Audiodrive based cards around 97 for basic cards I had several in the day. For PCI in the Pentium II era, Sound Blaster Live cards which are PCI cards. I had those as well, later the Audigy cards came out, which I still have an Audigy 2 I believe, but I haven't used in a decade or...

    VIC-20 project ... case badge needed

    I have not seen Vic20 badges (embossed that is, I did find these: http://www.amibay.com/showthread.php?82379-VIC20-VC20-replica-paper-label-case-badges they aren't embossed, and the thread hasn't updated in awhile). I don't know if this seller would be interested in making them though...

    Hello from Pennsylvania

    Well, I mostly missed the 8bit era. Unless you count the 2600 and NES, as that is what we had as kids. We never had a 8bit computer around in the 80s. I did have an old TI99/4a at some point in the early 90s or mid 90s, but no magazines and not much to go on. I ended up with some old still...

    New Project

    If you are using a Windows OS, you can open your photos (jpg etc) in "Paint". Then choose "Resize" and scale them down, and re-save as jpg. That is what I do to get them more reasonable for forum or blog postings. Certainly there are other options and programs. I used to use a image resize...

    Looking for your opinion

    My feeling is generally that if it can be kept original I like to see that. There are less of the old machines that are serviceable or repairable all the time. I wouldn't sacrifice a working unit for a project like that. I would expect though that you could find a unit that is not practical to...

    Best options for Commodore 128 video out?

    It was just simply following a schematic. Nothing special, I just likely did something wrong with the other circuit, or had a bad connection on the breadboard somewhere. I am going to try H2Obsession's "Ultimate" circuit, which includes color correction. I just need to wait on the one 74148...

    Best options for Commodore 128 video out?

    I had found the schematic of a simpler resistor and circuit with a little mosfet that I figured I would try. Dark Green looks a bit off, maybe the basic command was wrong. The first time I turned it on it was a bit glitched. I turned it back on and it came up to the proper screen as seen in...

    Best options for Commodore 128 video out?

    The issue was not the 7400. I get the same thing with the proper XOR ic. Ya, I don't like plugging unknown hardware into these things. I did what checking and what testing I could before doing so, which was verifying the XOR. Having it on a limited power supply and watching for any spike on...

    Check out my Pi1541 Build

    I do really like that 3d printed case, but I don't have a 3d Printer either. So I went with something I happened to have laying around (yes it wasn't reasonably repairable). It was not quite finished when I took this picture of it. It has been a great device. I probably put way to much...

    Best options for Commodore 128 video out?

    As I expected it is a bit more work that I am interested in, and apparently about anyone else as there is no such product as far as I have seen. Not to mention well above my abilities and understanding of the subject. Anyways, I did finally figure it was worth risking connecting up the circuit...

    Help with Bartop arcade plans

    The way interpret that is, the bottom one is the (D) Control Panel. The view you are referencing is a kind of X-Ray View showing where the cut pieces go in relation to the side panel. The upper one, I believe is where the front of the Monitor gets aligned to, and is not a MDF Piece. There is...

    Best options for Commodore 128 video out?

    I kind of wondered if there may be a better way to take the Digital RGBI to HDMI modern Digital. I figured the signal differences are to great for a simple solution. RGB is for driving the electron guns in a CRT. I expect modern Digital HDMI/DVI are optimized for LCD technology and don't have...

    Plastics in the Dishwasher?

    I guess different dishwashers will get hotter inside than others. Mine makes my counter quite warm. I wouldn't risk it. My concern as well would be melting, or even some deformation. Different plastics have different melting points. Printed Key Labels, may also be removed in the dishwasher...

    I have started a Bartop Arcade cabinet.

    I used 3/4" MDF, the only catch there, was the double stacked sides was then 1.5" thick. The blade on my jigsaw would retract to less than 1.5" long. It extended out far enough though, it was very slow cutting. I went through two 20V lithium batteries on my jigsaw and was pretty hard on the...

    Best options for Commodore 128 video out?

    I have what I need to try it out, now I just need the time to put it together. I don't know when that will be, maybe I'll find time this weekend to do a simplified prototype like H2Obsession's original design, then if that works, I will try the 7400 for sync.

    I have started a Bartop Arcade cabinet.

    I have started a bartop arcade based on the Geek Pub 4.0 Plans. The only issue I had to get started was that I didn't find any information on the radius of the Compass to make the marks for the sides. If it was to short then I would not have been able to get the second side mated into it and...

    Best options for Commodore 128 video out?

    I was tinkering with H2Obsession's RGBI to SCART design this evening. This is something like I plan to try to do up on a breadboard or such to see if it works. It is a hybrid of his designs. I should be able to use it with the GBS units or SCART output, and maybe possibly the proper model of...

    help with a 20x4 lcd display on a teach pendant

    I don't know enough to say. You need to figure out what the power pins are, what the data pins are and find a LCD Library that supports the HC20401. If you find a Library that supports it, there may be info there as to the 16pins pinout. With that you should be able to test it out. You...

    help with a 20x4 lcd display on a teach pendant

    I will doubt that it would be compatible with the cheap 2004 LCDs, but they may. If so you should be able to find some info somewhere on it. You need to find a datasheet for the screen. You need to be certain of the part number. Connecting a 2 row screen certainly wouldn't work, at least...

    help with a 20x4 lcd display on a teach pendant

    Is there any chance of getting a picture of the back of the board? Also it may be helpful if you can get a picture of the blocks while it is powered on. It looks close to the 2004 (20x4) displays, it would have to be electronically compatible as well to be swapped with one though. You may...
