Computer Education in Schools Instruction Language (CESIL)

When I first learned programming in about 1978 the school I attended was lucky to have a Research Machines 380Z on which there was the BASIC language. Using this one of the pupils then wrote a CESIL interpreter for their (I guess) O Level project. Other pupils then used this to learn the fundamentals of programming.

Skip forward a few years and I now owned a Sinclair ZX Spectrum having also previously had a ZX81 too. I decided that I would also write a CESIL interpreter this time using Sinclair’s variant of BASIC. Remarkably I still own the sheets of … Read the rest

In the Days Before Digital Downloads

Digging through some old papers I came across a letter that I wrote to the magazine Your Computer in 1981 when I would have been 16.

Even before my love affair with Psions begin (see previous post) I was a Sinclair addict. Originally it was just a ZX81 with the obligatory wobbly ram pack but quickly I had moved onto a 48K spectrum with dual microdrives, a printer and interfaces 1 and 2.

All of this came flooding back when I found the following animated song by Rob Manuel. Brilliant!!!… Read the rest
