I recently upgraded my Tandy 1000 TL/2 with a Diamond Speedstar ET4000AX card. Now, I have used the VSWITCH utility in the past, but had to use separate VGA & CGA monitors to do it. I wanted to do the same thing here, but did not have enough room to fit two monitors in the space I have available. I …

I decided to download the archive.org collection in addition to what was on YouTube. I only did the MP4 version as the MPEG2 would have been over 600GB! Even the MP4 is better than what was YouTube after taking a closer look. The other added bonus is the episodes are organized by season and episode …

I just got done downloading the 433 available episodes of Computer Chronicles available on YouTube. It's pretty amazing to see how far technology has progressed since the early 1980s. I just got watching an episode from 1983 about Microchip Technology. One of the topics of discussion concerned was …

I checked Digikey, AliExpress, JameCo and eBay, plus searching on Google. Any ideas where to find one of these? If one is not too expensive, it may be worth trying to …

Yes, there were at least three variants of SpeedSTAR24, see the pictures in this thread: https://www.vogons.org/viewtopic.php?f=63&t=77372 Thank you for pointing out that thread. It appears that different RAMDACs may require specific BIOS from Diamond to work properly. I could put another RAMDAC in …

If I had to guess, Diamond simply made several different versions using the same board and stencil. I've seen versions of the SpeedSTAR 24 with a Sierra SC11483 15-bit DAC too. Fitting a 24-bit capable RAMDAC (try looking for the SS2410 or Music MU9c1880, those are the same chips that the 24-bit …

I picked up Diamond SpeedStar24 ISA video card with BIOS version 5.01, but every test I run only indicates a 256 color RAMDAC, including Tseng Labs own VESA driver and UNIVBE. The RAMDAC is a Samsung KDA0476PL-80. The datasheet seem to indicate that is truly only capable of 256 colors. I have seen …

I know Norton SI 8.0 is not the most accurate benchmark, but running at full speed the score for my LS486E with a Pentium Overdrive is 264 and shows 83Mhz. De-turboed the score drops to 66 and shows 20Mhz.
