  1. If I spent the money and time to install the composite mod in my system, what could I expect the overall video improvement to be?

     

    It's decent, but it's no S-Video - you really got to go with S-Video. Once you see the difference you'll never want anything less.

     

    Yeah, but the A/V mod works nice too. I did a couple of consoles back in the day, and you can really tell the difference.

  2. Looking at an October 1975 BYTE magazine I saw only two machines being advertised: The Altair and the Sphere. The Sphere was supposed to have BASIC, a keyboard, and a display. There is a Wikipedia article on it: Spere 1. It looks like about 1,300 were built with half of them being sold as complete systems (not in KIT form).. There was also an article in the Oct 1975 BYTE and a 2006 followup about the Sphere: http://www.swtpc.com/mholley/BYTE/Oct1975/are_they_real.htm

     

    The guy who built it is still in business: http://www.a-systems.net/company.htm

     

    I just found out some info about Gordon French's Chicken Hawk computer from 1975, but it doesn't say if it was commercially available, or if it run BASIC.

     

    Really cool about the control-alt-delete keyboard combination, really good info.

  3. That is impressive. I realize the computers of that day are simple by today's standard, but you also have to consider that a lot of the components that were in large supply back then are hard to find now (or are in different packaging, etc.) Very nice.

    I think all these old machines were impressive.

    Most of the board layouts were by hand, there are no programmable devices on most machines for several years, slow parts make timing even more critical, parts were expensive so you tried to maximize the use of the gates on your chips which makes board layout even more difficult, and most of the software/firmware was developed with limited development tools.

     

     

    Now you draw the board layout on screen, the software can auto-route a board in a couple minutes (though it usually needs tweaking), you can program large portions of a circuit into programmable devices, parts are cheap, and you have cross development tools capable of building and programming a ROM with little effort. You can literally do in hours what used to take days or weeks.

     

    I totally agree! I am amazed of the things they did back in the 60's and 70's with the early computers.

  4. Why on earth do you want to do that? :?

    Only to make sure it is cleaned out. If it comes to unsoldering, that's where I'd draw the line. I just thought maybe there is a way I hadn't figured out yet.

     

    Why would you do that?? :?

  5. Keep in mind the AIM-65 and other machines may have been available complete with BASIC in '76. I'm not sure when the AIM-65's BASIC became available and if you had to plug in the ROM or if it was available pre-installed.

     

    Those types of computers would be stretching the definition of recognizable personal computers for their lack of standard displays alone. We're still looking at 1977 and the Apple II, Commodore PET and TRS-80, in that order, and trying to figure out where the SOL-20 fits in the mix...

    Where in the original post does it specify what display was used?

     

    I would think a computer with some type of recognizable display output would be a given for this particular discussion, no? In other words, we'd want to eliminate blinking light displays and things like on-board red LEDs.

     

    Then the Altair 8800 wins: it had a keyboard interface, it had a video display (Cromemco Dazzler card i.e.), it had BASIC, and it was sold as a kit or assembled.

  6. The Apple 1 also reads BASIC from a tape:

     

    "According to the Apple-1 Cassette Interface Manual, it was necessary to make another change to the motherboard in order to use the interface. Besides removing the jumper that relocated the 2nd 4K of RAM, another jumper had to be added to the motherboard in one place. Then, after the interface was properly installed, an assembly language program would be available at $C100. This program allowed operation of the cassette load and save routines. To load Apple BASIC, the user would type “C100R” and press “RETURN” on the keyboard (this instructed the Apple-1 Monitor program to run an assembly language program at the address $C100)."

  7. I found my information online, also the SOL is mentioned in the book 'Hackers'

     

    The computer was presented in NYC in February 1976. It has some software and an operative system. I found online that came with a BASIC tape, but the book doesn't say anything about the SOL using BASIC.

     

    Another early computer was Cromemco's System 1, but I think the SOL came out first.

     

    The truth is, all the people working on personal computers at the time were working together, I guess that's why all the system's seem to pop-up at the same time.

  8. Honestly im thinking of just opening up the cord and replacing the tip, how hard could that be? even if it doesnt work i can just fix it

     

    Edit:

     

    Nop, he/she needs this

    I am a he thank you very much!

     

    No problem, I didn't know and I was trying to be gender/politically correct.

    I was just joking anyway.

     

     

    I just picked up the adapter at radioshack. I still have scroll and all of my games just show up as a jumbled mess, though I can recognise sprites and on a few i can actually move the carachter. any solutions?

     

    Is the console or the games in the PAL format? Are you in the US? Maybe someone with more experience can chip in?

  10. I knew this was too good to be truth... :|

     

    Wait, what?

    The whole 'I'm not releasing the game' I mean, I know it is YOUR game (looks excellent by the way), but think of the children!! :D

     

    Please!!

    Oh come on, 90% of the stuff on Youtube is trash. People that doesn't know anything about video editing should be forbidden from posting videos on Youtube.

     

    And also anyone who cannot use a tripod to hold the camera.

     

    However, it is funny watching them trying to operate the lynx (or whatever) with one hand.

     

    Tripod? What's that? :)
