Der UMC-Chipsatz UM82C491\/UM82C493 versorgt eine CPU im Socket 3, vom 486SX bis zum DX2-66, dazu bis zu 256 KB Cache und bis zu 64 MB Speicher auf acht 30-poligen SIMM-Pl\u00e4tzen. Das Besondere sind die drei VESA-Local-Bus-Steckpl\u00e4tze: Grafik- und Festplattenkarten bekommen dort einen 32-Bit-Bus statt des lahmen ISA. Genau diese Kombination macht 486er-VLB-Boards zur Lieblingsbasis f\u00fcr schnelle DOS-Spielerechner. Unter den Revisionen 1.0, 1.1 und 1.3 ist das Board gut dokumentiert, die Rev. 2.0 taucht in den Datenbanken dagegen kaum auf.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Was ist ein Preview?<\/strong> Hier zeige ich kurz Hardware, die ich entdeckt, aber noch nicht genauer angeschaut habe. So behalte ich den \u00dcberblick und ihr seht schon vorab, was kommt. Sobald ich dazu komme, ersetzt ein ausf\u00fchrlicher Beitrag das Preview. Was zuerst dran ist, bestimmen eure Kommentare oder meine Lust und Zeit ;).<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"ansichten\"><span class=\"ez-toc-section\"
