    Converting a PC Booter Game to Cassette Tape

    I suppose I should have included the quotes: "sound circuitry." But since krebizfan didn't, I just decided not to begin another discussion.

    Converting a PC Booter Game to Cassette Tape

    Exactly. TSR-80s have cassette ports, we have to have them too. Tandys can work with TVs... In fact, back then some of the people who bought this stuff for home use didn't even know WHAT they we going to do with it. They wanted to be sure they weren't left out of the future, but they didn't...

    Converting a PC Booter Game to Cassette Tape

    I think these are both evidence that IBM was trying to cover all the bases. Though they were probably thinking mainly about the S-100/business market, why not include school and home markets? After all, the industry was still evolving. The dealers could always be steering customers to where...

    Converting a PC Booter Game to Cassette Tape

    Exactly. Technical sense doesn't always make it in the real world. Non-technical obstacles can add unnecessary steps sometimes.

    Converting a PC Booter Game to Cassette Tape

    I was considering that nice, "perfect" digital audio recordings of programs would be more reliable than analog cassette recordings when played. This would be preferable if publishing through an audio medium. I agree with your point. In practice it doesn't necessarily follow that a more...

    Xenix 3.2 Programmer Needed (Help)

    While it's not Xenix source code, there is System III source available here: https://minnie.tuhs.org/cgi-bin/utree.pl?file=SysIII/usr/src I hope that helps.

    Converting a PC Booter Game to Cassette Tape

    Thanks for that! It looks like an interesting addition for this thread. Great, then I have a little more about this: Okay, now I'm confused. Granted most computers that had a cassette port had business software available on cassette. I also agree that a cassette-based 64K IBM PC was more...

    Converting a PC Booter Game to Cassette Tape

    Plasma and krebizfan make a good case against audio storage taking off on the IBM. Just in case anyone mistakes the tone, what follows below is not me trying to start an argument, flame war, or make personal attacks. I'm just proposing an alternate view of what might have followed IBM...

    Amstrad PC 2286

    Inserting a VGA card in a slot will not be the only thing you have to do to try getting video output external to the onboard Paradise adapter. You have to deactivate the "internal VGA" first. That is done with an option link (AKA "jumper" for the rest of us). All the relavent info regarding...

    Amstrad PC 2286

    That's what I was thinking when I questioned the transformer's condition. Also, I thought that voltages higher than expected coming from the transformer might point to it being faulty. Wouldn't this be a correct assumption?

    Converting a PC Booter Game to Cassette Tape

    That's unfair! Stealing a guy's idea 38 years before he thought of it. At least they didn't get the audio CD angle! Seriously, though, I agree that the cassette port is ironically more interesting now than when it came out. I think mogwaay/Chris's XTjr is a great design for this kind of...

    Amstrad PC 2286

    What about the transformer itself being faulty?

    Converting a PC Booter Game to Cassette Tape

    I for one like seeing this project! Imagine being able to get use out of your cassette port for programs that should have been available for it back then. PC booters are a great choice too, since they make you have to reboot when you're finished playing (like those other computers that only...

    Amstrad PC 2286

    All four are confirmed as polyester capacitors. C614 & C615 are 0.1uF, C631 & C634 are 0.033uF. But, if I traced correctly, they go right to the AC in! I'm hoping to send you pics of the PCB by the end of the week. So, it might be good to hold off on ordering replacements for these until...

    Amstrad PC 2286

    OK, it's not for sale. But, can they scan from it for you? Is it possible to look at it in any way?
