hueyjones70 Posted December 15, 2019 Share Posted December 15, 2019 I like to buy 800XLs, upgrade them and resell them for a small profit. I can do video upgrades (usually SV 2.1), install UAV, install memory upgrades, (Wiztronics or Rambo), and generally clean them up. I usually sell on eBay but I would be willing to do business with forum members without the fees associated with eBay. Anyone interested can message me and work out details. 1 Quote Link to comment Share on other sites More sharing options...
+OLD CS1 Posted December 16, 2019 Share Posted December 16, 2019 For the non Atari-inclined (like myself, who owns an 800XL and a 130XE but does not know the lingo,) could I impose upon you to explain the upgrades and what they do? Quote Link to comment Share on other sites More sharing options...

The SuperVideo 2.1 changes some resistors and capacitors in order to separate the Luma (black&white) signal from the Chroma(color) signal so that you don'd get colored objects bleeding into each other. It also sharpens the pixel definition. The UAV (Ultimate Atari Video) does this with an add-on board that is plugged in to the motherboard. The Wiztronic and Rambo upgrades increase the RAM from 64K to 256K. 1 Quote Link to comment Share on other sites More sharing options...
