I-O Data PK-X486/87SL Cyrix 25MHz 286 to 486 Upgrade Card PC-9801 / Tandy 1000

Description: For sale is a rare I-O Data PK-X486/87SL upgrade card for PC-9801 series computers, that will also likely function in Tandy 1000 systems. Somewhat similar to the Make-it-486 type card. Card features a Cyrix Cx486SLC at 25MHz, with a Cyrix Cx87SLC math coprocessor. Will fit into the TL, TL/2 or TL/3 mainboards. The four dipswitches: switches 1 and 4 have no function, switch 2 disables/enables the math co-processor and switch 3 should be set to off on Tandy systems. Please carefully check compatibility with your system. Fast shipping from Tokyo, Japan. Free to the US, affordable shipping rates to the rest of the world. Please be aware of customs import fees in your country, however this falls within the duty free allowance for the U.S. and no import duties are likely due. Also be aware of possible customs processing delays, particularly in the E.U. Keep in mind that this is vintage equipment for vintage computers. Very specific knowledge of its era is required. Please carefully check your use situation and software/hardware compatibility. In other words, I’m not your tech support (but am helpful!), nor am I responsible if something breaks during installation. I ship within 24 hours most of the time, but when shipping falls late on a Saturday in Japan, shipping will not be until Monday.
