Can the IBM PCjr be upgraded to support the better features of the Tandy 1000?

The PCjr supports three-voice audio; the Tandy 1000 copied that so running games in Tandy mode should work on a PCjr too. Some games might need a small program to switch to three-voice audio on first. ...

How to do the Tandy 1000 audio mod on a PCjr?

According to this post on Mike’s PCjr forum, the audio mod should only require connecting pins 5 and 9 (and perhaps 2) on the MC15429. However even that’s apparently not necessary: this other post has ...

This will work with the USB floppy drive you have mentioned, a Chuanganzhuo one, using Windows 10. You have to use a proper Double Density floppy disk, not a High Density one. I tried it with a High ...

Is the IBM 5153 color display compatible with the Tandy 1000 16 color modes?

CGA 40-column text mode is 320x200 16-colors and 80-column text mode is 640x200 16 colors. Those are a completely standard feature of CGA and therefore a completely normal thing for a CGA monitor to ...

Is the IBM 5153 color display compatible with the Tandy 1000 16 color modes?

Basically yes. TGA (1000EX or similar) signal output (colour/intensity and sync signals) and connector pinout is upward compatible to CGA, thus compatible with CGA monitors. Both produce the very same ...

Is it possible to convert a Tandy 1000 EX video signal to SCART?

It would seem that a 1 to 1 mapping between RGB (CGA) connectors and SCART is not possible and therefore passive adapters are not available. There are open-source schematics to help make this ...
