That's a zx81 mate!, and it did not actually plot a true pixel but printed a character on the screen. But then you are comparing a ZX81 to a Commodore 128, that's not even like comparing apples to pears. -- Robert van der Veeke (Remove the pin to Email) Currently listening to: Ben Hur - Miklos Rozsa So... if she weighs the same... as a duck... then she's made of wood.

In a lot of data transmission formats, it takes 10 bits to transmit one character so 60 chars/sec would be 600 bps. Tom Lake

More like comparing mice to elephants. -- ______________________________________________________________________________ | spike1(a)freenet.co.uk | "I'm alive!!! I can touch!

I was going off my previous god knows where I got it from calculations from last night. :) I wasn't drunk, but it was late and I was obviously verrrrr, verrrr tired.

I think more important than the sprites, the Spec could really have done with a couple of more bytes for pixel colour. A real crippler. Is there any example of a Spectrum game that couldn't be matched or bettered graphicwise on the C64? (and consider Head Over Heels while writing your reply). So everything that you could see or hear from the C64 was better, obviously if you could bloody poke it into doing the thing. |
