If you want to play it again, search for MAME (Multiple Arcade Machine Emulator)... then find somebody who's got the ROM images
It's the Real Thing (TM CocaCola Corp) in that it emulates the original hardware (6502 at 1MHz with custom vector graphics hardware for the display, in BattleZone's case - same as Asteroids), and runs the original ROMs... you even have to sit through the hardware self-test routines, as if you'd just powered up the machine
And you can configure the DIP switches that control the scores at which bonus tanks and suchlike are awarded - or make it 50p a game, if you want (configure CoinSlot2...)
The ROM images are copyrighted so it's illegal to distribute them and the download sites keep getting shut down - so even if you PM me I can't possibly give you a copy of my copy
Pong was mainly done in TTL rather than softwareComment

Originally posted by BrowneIssue View PostI've just remembered a third - a C programmer who said 'informationals and warnings don't count'. This was the bod that added 'one' or 'two' or 'four' or whatever to a bit flag to turn a bit on and added it again to turn it off. I spent an afternoon trying to explain what XOR was for but he was having none of it. The bugs he caused used to drive me mental. (E.g. every 16th press of RETURN would alternately turn the cursor off or on.)
We farmed out a conversion from (IIRC) the Spectrum to the C64 to a local teenager who, in principle, was a competent programmer.
The test versions he delivered always suffered from dreadful sprite flickering (almost impossible to achieve on the C64) which he dismissed as an inevitable consequence of implementing such complex graphical operations, which had in any case been optimised for the Spectrum way of doing things.
Upon finally taking the code in-house, in the vague hope of actually turning it into a deliverable product, we discovered such delights as the way he added 100 to the score, which was to loop over the addition of one to a 16-bit value a hundred times.
To give you an idea...
Code:.add100toscore LDA X, #100 CLC .start LDA score ADC #1 STA score LDA score+1 ADC#0 STA score+1 DEX BNE start RTS
Code:.add100toscore CLC LDA score ADC #100 STA score LDA score+1 ADC #0 STA score+1 RTS

The reason for the sprite flicker was that it could take up to a quarter of a frame (about 5ms in the UK) to update the score as necessaryComment

It's slow in here this evening.
I was in Stonehenge at midnight once, just a few candles here and there and some people gently drumming or playing bodhrans - autumn equinox eve 1987, IIRC.
There weren't many of us there, but it was conducive of a contemplative state of mind.
Sometimes slow is goodComment
