retrocomputing community

Programmers are sharing jokes and memories about Cray, the legendary supercomputer maker whose machines defined high-performance computing in the 1970s through the 1990s. The exchange blends retrocomputing enthusiasm with irreverent humour, as users trade anecdotes about the iconic machines and early programming on them.

A retrocomputing enthusiast has written a short recursive Dr Logo program that draws a Sierpinski triangle on a Schneider CPC6128, letting the turtle graphics cursor do the work. The fractal is produced by an elegantly compact routine, and the example is being shared with fellow fans of vintage 8-bit home computers as a showcase of how well-suited Logo's recursion is to fractal graphics.

A nostalgic nod to IBM's old marketing has been shared among retrocomputing fans, highlighting a vintage advertisement about having everything for the 'professional on-the-go'. The post is part of ongoing online enthusiasm for vintage tech and early computing, where enthusiasts regularly share and celebrate old hardware, adverts and IT memorabilia.
