Re: Pretty fast Mandelbrot set generator...

John, To zoom from the center add these four lines

431 LET X = X - XI * 16
432 LET Y = Y - YI * 12
441 LET X = X + XI * 16
442 LET Y = Y + YI * 12

That should do it.

The motherboards did work when I put notes on them, but you should consider everything "for parts" NOT WORKING. $30 in...

Huge Sinclair Book collection for sale.

I have a giant collection of sinclair books (mostly for the ZX81/TS1000). I have run out of space and I need to sell them. It would be great is someone wanted the whole collection, but I will sell them in small groups (too expensive to ship one book). I would prefer to ship to the U.S. again because...
