Happy Birthday ZX Spectrum

Did you try killing Elrond by over feeding him ?

Oh the joys of 2 colours per 8 pixel square and raspy sound effects!

Not forgetting inserting a machine code "ret" command to bypass the fast loader.

Brings a tear to the eye

Happy birthday Speccy!

My father told me that the spectrum was born when Sir Clive got his mitts on a batch of damaged Z80 chips originally intended for washing machine programmes. Half the chip was blown, but half usable. The ZX Spectrum was designed around the working half.

Urban myth?

Given that Sinclair had already sold about 1.5 million ZX80s and ZX81s, all containing a Z80 microprocessor, it's probably safe to assume he could get hold of fully operational parts if he wanted them

Started off with a zx81 and added a 16k ram pack.

Moved to a Spectrum 48k but also bought a C64 which I preferred cos I wrote a sequencer accessing the sound chip on board. Actually gigged that baby plugged into the PA system playing bass lines - way before Thomas Dolby et al appeared on stage with a computer and cheap telly.

Had a QL and Spectrum+ too as well as a wee printer using thermal paper that used to go black after a while.

C9

I can't remember the others, but C9 sticks in my head. Though that was from the Oric-1, because we were middle class and only common people had speccys.

C9 on a 6502 is "CMP #" or "compare immediate"
C9 on a Z80 is "Ret" or "Return"
