Plan 28 is working towards building Charles Babbage's Analytical Engine. For the latest news follow the Plan 28 blog.

Plan 28's donation system is now online through JustGiving. Donations can be made in British Pounds, US Dollars, Euros and a number of other currencies. As a UK charity Plan 28 is eligible for GiftAid; tax payers in the UK can help the charity by signing the GiftAid form when they make a donation.
