A Late Correction
Four bytes went missing off the end of the listing for “Son of Mandelbrot”. The article appeared in the January 1990 edition of “Your Sinclair” (neé Spectrum) and has only just reached the attention of “AH Trewartha” who submitted the article.
As shown here the listing will only give you 2 “shades” (white and 50% grey) of your mandelbrot set. you need to add the following bytes on the end:
03 01 03 03
to give you the other two shades (75% and 100%) which justifies having “shades” at all really.
Dear Your Sinclair, WHERE IS MY CASH?? Also, a screenshot would have made the article a bit nicer, made the poor reader typing it in realise the listing was faulty, and filled up the page to boot! (i.e. rather than complaining my BASIC wrapper was a “bit crap”.)
On the other hand I had to disassemble the code in order to work out what had gone wrong, and as that’s my idea of fun: well done you.

Hey Alan, I don’t suppose you could post a link to this prog in an emulator. It would be great to see your work (or even YouTube it?)
Isn’t there a joke about a prog in an emulator?
Or is there one about a gooseberry in an emulator and another about a prog in a liquidiser?
Prog in an emulator
Coding it up as I’m going [0/10 see me]
Has anyone heard anything more about world’s dodgiest tribute band, The AeroSmiths?
why lookee here: java emulator with “Son of Mandelbrot” loaded in (uncorrected)
maybe i’ll make some screenshots of the corrected version
actually you can correct it yourself in that emulator. press space to interrupt the rendering and then:
POKE 60240, 3: POKE 60241,1: POKE 60242,3: POKE 60243,3
RUN 20
