Browser [](https://os8088.com/spotlight/browser/)My latest experiment ## [A web browser for the IBM PC XT](https://os8088.com/spotlight/browser/) os8088 now fetches real web pages and lays them out as text and tables, over an Ethernet card or a parallel cable to a DOS machine standing next to it\. The network is not the slow part: drawing a window full of text takes longer than fetching the page\. the browser13,889 bytesthe stackARP to TCPmachine4\.77 MHz 8088 RunCPM [](https://os8088.com/spotlight/runcpm/)## [CP/M, in a window](https://os8088.com/spotlight/runcpm/) CP/M was the operating system small computers ran before the IBM PC existed, on a processor the PC does not have\. os8088 now emulates that processor, so CP/M software runs here: the 1979 command processor at the prompt, Microsoft BASIC, an assembler and an editor, in a window you can drag around like any other\. emulatesa Zilog Z80written in4,679 lines of Cmachine4\.77 MHz 8088 Written in C [](https://os8088.com/spotlight/cword/)A new program ## [A word processor written in C](https://os8088.com/spotlight/cword/) Everything in os8088 up to now was written in assembly language, one processor instruction at a time\. There is now a C compiler for it, which is a far quicker way to write a program\. To find out whether it could carry something real, I wrote a second word processor with it \-\- and it turned out too big for the memory a program gets, so it comes in two pieces\. written in8,350 lines of Cthe program54,450 bytesmachine4\.77 MHz 8088 Microsoft Word [](https://os8088.com/spotlight/word/)A new program ## [Microsoft Word, on an 8086](https://os8088.com/spotlight/word/) I have added something I have wanted to see for a while: my own os8088 version of Microsoft Word 1\.1a\. It has the familiar 1990 menus, uses the same clever tricks to show bold and italics on a plain old PC screen, and saves Word \.DOC files\.

Almost nothing used both together\. os8088 now spans one desktop across the pair \-\- 1,360 pixels wide, on a 4\.77 MHz machine \-\- and a window that lands over the join is drawn on both screens\. monitors2one desktop1,360 x 348machine4\.77 MHz 8088 Frotz [](https://os8088.com/spotlight/frotz/)A new program ## [os8088 plays Infocom games now](https://os8088.com/spotlight/frotz/) A Z\-machine interpreter in 23,722 bytes of 8086 assembly\. The Z\-machine is the pretend computer Infocom invented in 1979 so one game could be sold for every machine at once \-\- which is why a story file from 1982 is still a plain file that still runs\.
