Return of the 8bit Bell Bottoms

@rc2014 I do hope that the server running on port 8080 only uses #Intel8080 instructions
@mattgodbolt `XOR EAX, EAX` is the descendant of `XRA A` on the #Intel8080 (aka `XOR A` on the #Z80). On those machines saving a single byte vs the two bytes of `MOV A, 0` *really* mattered, both in terms of not wasting any of your precious few kilobytes of memory but also avoiding the time taken for an extra fetch from memory. You could tell an experienced machine coder by whether they used this optimisation, which is now over 50 years old!

Space Invaders: Tempo-Änderung im Spiel durch zufälligen Prozessor-Effekt
Viele von euch kennen den berühmten Tempowechsel im Space Invaders Arcade-Spiel. Doch nur wenige wissen, dass nicht geniale Programmierung, sondern ein Hardware-Zufall dahintersteckt.

Space Invaders: Tempo-Änderung im Spiel durch zufälligen Prozessor-Effekt

Ein Hardware-Fehler beim Intel 8080 sorgte zufällig für den berühmten Tempozuwachs im Spiel Space Invaders. Was steckt technisch dahinter?

Apfeltalk Magazin
I've heard it said the #mailstation firmware was produced by an 8080 compiler that was unaware of #z80 extensions, so I checked an #intel8080 instruction table and nope, even the 8080 could INC (HL)! So chalk up some more bytes and cycles for a less-than-brilliant compiler.

I put together most of my retrocomputing bookshelf while learning Intel 8080 and CP/M programming, which reflects in the selection of titles. For more great photos of retrocomputing bookshelfs see:
