Computing History – The UK Computer Museum – Cambridge

Posted by jpluimers on 2020/06/19

On my places to visit:

The Centre for Computing History is a computer museum based in Cambridge, UK. With a collection of vintage computers and game consoles, many of the exhibits are hands on and interactive.

[WayBackComputing History – The UK Computer Museum – Cambridge.

When I bumped into it, this was their collection size, ranging from the 1960s until recent history:

Archive Statistics :

  • Computers = 993
  • Peripherals = 1446
  • Mobile Devices = 31
  • Game Consoles = 213
  • Video Games = 10259
  • Software Packages = 2605
  • Books = 2045
  • Manuals = 4106
  • Magazines = 9057

Looking at their archived brands (having [WayBack] MITS – Altair and [WayBack] Raspberry Pi in the collection) is such a joy.

Archiving the older parts is a tough job, as they stem from way before the web era, so information has been lost, parts are hard to source, a lot of hardware got thrown away or is hard to find at all, people have died. More on that at [WayBack] About – Computing History.

Without a physical visit, you can find what they have at [WayBack] Search Our Archive – Computing History.

The video below on their archive is impressive.

Apple Tesseract 1992 prototype (not Tessaract)

Posted by jpluimers on 2016/12/23

A while ago that bitsavers published a picture of an Apple 1992 Tesseract Motherboard.

It’s from the 68k to PowerPC RISC transition Apple made in the second half of the 1980s and first half of the 1990s where several groups within Apple were working on new equipment.

More details of those are here:

Note this is not [Wayback] TesSeRact from the DOS TSR (Terminate and Stay Resident) days:
