Things are tough right now ...

They're tough for everyone :( But when coronavirus hit here in the UK, the museum had to close its doors to the public, and we lost practically all our income overnight.

Please Donate Via Just GivingNo visitors, no workshops, no events, no school visits... no income. We know that things are tough for everyone right now, but if you can afford to help us through these tough times please donate what you can.

Stay safe, stay at home! There's over 36,000 exhibits here! That should keep you occupied for a bit - get searching!

Texas Instruments TI-59

The Texas Instruments TI-59 is an early programmable calculator released in 1977. It is the successor to the TI SR-52 with four times the number of program steps. The TI-59 was a more advanced version of the TI-58, both of which were released in May 1977. The TI-59 retailed at £249.95 compared to £99.95 for the TI-58.

They both contained new technology trademarked by Texas Instruments as Solid State Software, providing you with complete, pre-written problem solving libraries in plug-in modules. The Master Library module contained 25 useful programmes. You were also able to key in your own programmes and store the data, using up to 480 programme steps or up to 60 memories, and use the Master Library programmes as subroutines. Optional plug-in modules were available to convert your calculator into a specialised problem solver in areas such as applied statistics, surveying, aviation and navigation.

The calculator can store data and programs on small cards that are read by a magnetic card reader on the right side of the TI-59. The calculator came with a number of these cards that were pre-programmed with functions such as volume, weight and temperature conversion as well as a random number generator and more complex mathematical functions. Blank cards were also included for the user to program.

The calculator could be powered from an internal battery pack or mains supply.
