    5 1/4” 720kb Floppy Drive Why? when? Where?

    All I could find on this subject is below https://www.vcfed.org/forum/forum/collections-community/general-vintage-computer-discussions/12461-dsdd-vs-dshd-vs-dsqd But I am curious what were 5 1/4” 720k DSQD disk drives used in and what years ? We’re these just a Commodore thing? When I was...

    1987 - Color Balloonjet Printer for photo machine

    I still have a collection of antique CASI Futura 100 Computer portrait systems and have always wondered what model/ brand a ballonjet printer could be? The driver is very early circa 1987 which is unusual indicating that only the prototype driver went forward into the 1990’s operating systems ...

    My ld100 has always been buggy and now is stuck in RGB mode and likes to drop green and blue channels. Has anyone gone through disassembly? It looks like a nightmare sandwich board scenario . Thanks Ryan

    WRP Web rendering proxy the gift of the internet to everyone that never happened

    WRP has been talked about since last century as a way to reduce bandwidth and allow full website compatibility on any system no matter how old. What we got instead of WRP were services like opera that require special software. Has any general purpose WRP been setup that you just type in a web...

    Why was VGA 640x480 w/256kb ?

    Time for the dumb question of the day. Something I’ve wondered since I got my Tandy 1000rlx was where did the non binary divisible 640x480 resolution come from? 640x480x16 colors is 150kb and runs roughly twice the speed of 15khz TV Most previous video standards had a resolution that fit...

    IBM 5151 Bad PSU, board swap with Compaq 410 possible?

    It’s amazing to think this project has been on hold 20 years but I’m probably going to start setting up some of my vintage machines again. In any event both screens are mono and seem to use the same HV voltage on the tube The Compaq has terrible screen burn and my IBM has a bad psu (deader...

    If a 286 can emulate a z80 or C64 why no console love?

    http://www.worldofspectrum.org/warajevo/Features.html Something I’ve often wondered ever since I was a teen and I played an emulated NES game on an old 386sx in 1995 is why were there no antique console emulators made for equally antique 16 bit PCs? The GameBoy was emulated in 1990 on the...

    We are trying to send moving 3d illistrations and and video to certain Wyse terminals, our security policy causes the server to do the graphics computing which uses a lot of its limited power.

    How to use Targa/TIGA as a stand alone card in DOS?

    I am having trouble getting the ATVista card working in the Pentium system I chose so I am moving down to a 486 box, thus far I have tried using various VGA cards with the Targa card but can't get the software to capture anything. I believe that I likely have address conflicts. I am going to...

    Truevision ATVista driver? Where to get Targa video suites.

    One fellow member generously sold me a golden original ATVista Targa video capture device. Now the problem, making it work. I am looking for the final graphics packages for the card but they don't seem to be in the normal places. My goal is to get this running under a pentium in either...
