Quote from: lightforce6128 on 03:54, 16 April 24From CPC 6128 I did a long jump to a 486 DX with 33 MHz, 4 MBytes of RAM, and a SVGA graphics card with a TSENG chipset that could easily be controlled also from BASIC. The storage was done with a 20 MByte hard drive. Also a SoundBlaster was available.On DOS there was DPMI to EASILY access every memory as one linear segment in 32 bits (Watcom C + Tasm FTW)
Especially for assembly programming on 486: Every register is an accumulator, every register is 32 bits wide, most commands are executed in a single cycle ... Z80 assembly is so much more complicated. But addressing on Z80 is simple: 16 bit registers, 64 KBytes of memory, and some additional banks to swap in. On DOS you have to work with small memory segments and six segment registers in addition to the register holding the address, also in combination with swapping in everything above 1 MByte. Only in protected mode these limits did no longer exist. But getting there was complicated ...
