A couple of months ago, I bought an adorable little 1989 Tektronix 222 miniature CRT portable oscilloscope locally on Facebook marketplace – I love old electronics test gear, and the 222 is particularly desirable among collectors due to its cuteness. The Tektronix 222 is a portable battery-powered 10 MHz dual-channel CRT oscilloscope with digital storageContinue reading “1989 Tektronix 222 Miniature CRT Portable Oscilloscope – Battery Pack Replacement”

1990s Apple Macintosh LC475 & M1296Z 12″ RGB CRT Display Repair
Early this year, a friend of mine asked me to take a look at their 1990s Apple Macintosh LC475 computer & matching 12″ RGB CRT display – these worked until a couple of years ago, but the LC475 was no longer booting & the CRT was no longer displaying an image.

Microvitec CUB 1431-MS CRT Monitor Restoration
I recently won a charity auction for a BBC Model B bundle on eBay (see my original blog post here), which included a Microvitec CUB 1431-MS CRT colour monitor, a common sight in British schools during the 1980s thanks to the BBC’s Computer Literacy Project. The monitor was rather worse for wear: it was coveredContinue reading “Microvitec CUB 1431-MS CRT Monitor Restoration”
My *New* Acorn BBC Model B
I recently won an eBay charity auction for a BBC Model B “Micro”, which came bundled with a Microvitec CUB CRT monitor, an Opus 5802 5.25″ FDD, and some miscellaneous items like joysticks and boxed games. What’s especially interesting about this machine is that it has been signed by Stephen Furber, the principal hardware engineerContinue reading “My *New* Acorn BBC Model B”
