Intel 8088 dos word writer5/17/2023 If any of this tickles your fancy, head over to ’s blog, microcore labs, and follow along. Or maybe you just want to play IBM XT games at insane speeds?Īnd it looks like has updated his 6502 emulation to include the undocumented C64 opcodes, so if you’re into that scene, you should be covered as well. By replacing the original Z80 with his emulation, he could diagnose the entire system, which led him to discover some bad DRAM chips and get the old beast running again. Why would you want an emulated CPU when the originals are still available? inherited a busted Osborne I, an ancient Z80 luggable. If this sounds familiar to you, it’s basically the same approach that used last year to bring us his replacement for the 6502 found in the Apple ][ and Commodore 64. The rest is a matter of emulating all of the instructions on the Teensy, which is more than fast enough to keep up. The PCBs basically adapt the pinout of the Teensy to the target CPU, with a bunch of 74VLC latches on board to do the voltage level conversion. Both of the “chips” run in cycle-accurate mode as well as in a super turbo mode, which can run so fast that you’ll need to use the Teensy’s internal RAM just to keep up.īoth of these designs have a hardware and software component. wrote in with not one but two (2!) new drop-in replacements for widespread old-school CPUs: the Zilog Z80 and the Intel 8088. Posted in classic hacks, Games Tagged 8088, cga, retrogaming, wolfenstein It’s possible that an 8088 may never be able to say yes to “Will it run DOOM?”, but at least now it can run the predecessor. The textures all need converting to CGA mode before they can be used and there are even versions for the shareware and paid-for versions of the game. Whether the gameplay survives in the sometimes-bizarre CGA color schemes and whether it becomes too pedestrian on an 8088 remains as an exercise for the reader to discover, but it’s a feat nevertheless. You can now slay virtual Nazis in 3D on an 8088 PC equipped with a lowly CGA card. Back in 1992 it needed at least a VGA card and a 286 to run, but here in 2023 has taken it back a step further. Their 1992 title Wolfenstein 3D might not have been the first to combine all the elements, but it’s arguably the first modern FPS and the first to gain huge popularity. When tracing the history of first-person shooting (FPS) games, where do you credit with the genesis of the genre? Anyone who played 3D Monster Maze on the Sinclair ZX81 might dare to raise a hand, but we’re guessing that most of you will return to the early 1990s, and id Software.
