This is my original IBM Personal Computer in all its 4.77 MHz glory, now finally working again after two blown capacitors put it out of commission when I last tried it a year ago. I got this PC, including the original keyboard and IBM CGA color monitor, many years ago from the original owner, who used it as his work computer (it had the company's ID sticker on the case). Originally a 256K dual-floppy machine, I added more memory, a multi-function board, and a 20 MB Seagate MFM hard drive. Once I get the CGA video board working again, it will be restored to exactly how I had it a decade ago. Amazingly the original battery for the clock/calendar still seems to be keeping the time somehow! As far as I can tell, the NiCad "blue barrel" battery is original to the multifunction board (circa 1987-1988) and has never been replaced. The keyboard error shown in the video was fixed by pulling off the Caps Lock key, blowing out the dust in the mechanism, and putting the key cap back on. I also give an example of how some classic DOS CGA games are *not* compatible with modern VGA video displays and will just show a garbled screen. ... https://www.youtube.com/watch?v=pFU1_ijINXc

Kodak's disc film was an ill-fated attempt to provide a more convenient alternative to 35 mm camera film. Unfortunately the extra convenience did not outweigh its disadvantages of only 15 exposures per disc and poor photo quality, so it never really caught on, and nobody makes new disc film anymore. This camera is still in its original packaging and even came with the original(?) Kodak batteries inside, which have absolutely no trace of acid or corrosion, and one of them even is still good! ... https://www.youtube.com/watch?v=TjOFog3F2BU

The $65 Rega Carbon phono cartridge is highly regarded by audiophiles... but is it identical to the Audio-Technica AT3600L which you can get for around $11? Let's take a close look and try to find out!

Copyright claims have been a constant problem with doing videos about audio equipment, so I purchased a library of music that I have the license to use in my videos without needing to worry about Content ID claims: the BackTraxx and BackTraxx II music collections from Digital Juice. These are from the early 2000s (or even older), so the music may sound dated by today's standards, but it fits right in with the retro equipment I make videos about. It turns out some of the music in the library actually dates back to the early 1990s: https://www.discogs.com/release/15228818-Robert-Rowe-Nature #copyright #contentid #music ... https://www.youtube.com/watch?v=ocax7LgWHZU
