I have a Commodore 64
It's a bit slow, and the 16 colors are starting to get too low for HD resolution, but I think it's still up to date.
Here is the specification
Microprocessor CPU:
MOS 6510 or MOS 8500 (the 6510/8500 is actually a modified 6502 with an integrated 6-bit I / O port, and the 8500 is a version of the 6510 with CMOS technology)
Clock: 0.985 MHz (PAL) / 1.023 MHz (NTSC)
Video hardware: MOS VIC-II, MOS 6567/8567 (NTSC), MOS 6569/8569 (PAL)
Text mode: 40 × 25, 16 colors
Graphic modes: 160 × 200 (can contain up to 4 levels per character), 320 × 200 (monochrome)
8 hardware sprites (movable graphics, for game programs)
Audio hardware: MOS Technology 6581/8580 "SID" chip
3 audio channels, ADSR programmable;
4 waveforms: triangle, sawtooth, variable square signal and noise
programmable bottom / top pass and bandpass filter
Oscillator synchronization, ring modulation
RAM:
64 KiB (65,536 bytes) (38 KiB for BASIC programs)
0.5 KiB color RAM (1K nibble)
ROM:
20 KiB (8 KiB BASIC 2.0, 8 KiB KERNAL, 4 KiB character generator with two 2 KiB case sensitive)
... JUST KIDDING !!! :icon_joke
Good luck all !
