Dropcheck Posted October 12, 2011 Share Posted October 12, 2011 Hi, Picked up this 800XL on ebay a week ago and I am stumped. There's a mod I have never seen. Was hoping someone could shed some light on what it might be. A black brick stuck in the OS socket. It goes to a 3 way switch that has US+, XL, XL Fix. I'd rather know what it is before I apply power. As usual the seller denied knowledge. Thanks, Quote Link to comment Share on other sites More sharing options...
Fox-1 / mnx Posted October 13, 2011 Share Posted October 13, 2011 It's an "Ultra Speed Plus OS" mod. Check here: http://nleaudio.com/css/products.htm http://nleaudio.com/css/products/ultraspdplus.htm Quote Link to comment Share on other sites More sharing options...
+bob1200xl Posted October 13, 2011 Share Posted October 13, 2011 Looks like two or more upgrades. The 'black lump' is a CSS UltraSpeed+. The little flat cable and IC mess looks like a memory expansion. Bob Hi, Picked up this 800XL on ebay a week ago and I am stumped. There's a mod I have never seen.

Dropcheck Posted October 14, 2011 Author Share Posted October 14, 2011 Does anyone have a install manual for the UltraSpeed+? http://www.atariage....plus-os-module/ Many thanks. I tried putting power to the board and guess what? It won't boot. So....... it's repair time. Never having seen or used this upgrade before I had no clue what wires were for what. Now I think I can see clearly through the mud. Quote Link to comment Share on other sites More sharing options...
bobotech Posted October 14, 2011 Share Posted October 14, 2011 Oh that sucks that it won't boot. It IS cool that it has some upgrades but now you will be fighting a couple of battles. First one is to figure out if the machine is not booting because of the upgrades or did it just fail. Then you gotta figure out if the upgrades are done right once you get it up and running. First thing I would do is to reseat all the chips on the board to see if its something simple like that and go from there. I'm just curius, do you have a picture of the full board including what the ribbon cable attaches to on the other side that isn't in the picture?

Dropcheck Posted October 14, 2011 Author Share Posted October 14, 2011 (edited) Here's the full board view. I do have a question about why there's an on/off switch connect to U7 chip? Found my answer I think, was reading the pdf from the link and it appears to be an additional option dealing with renumbering drive numbers. Hummmm....

bobotech Posted October 14, 2011 Share Posted October 14, 2011 You got some neat stuff in there. I wish I had an upgraded XL/XE. Wish I could be of more help but free bump anyway. Quote Link to comment Share on other sites More sharing options...

My 1200XL stopped working a few months after doing a bunch of upgrades. After testing a few theories with no results, I decided to just start transfering all the upgrades one at a time to another 1200 mobo. Then return the broken 1200 to stock and repair if necessary. But I'm lucky to have a second working 1200XL and a brand-new old-stock 1200 mobo for the "future" which is now. Quote Link to comment Share on other sites More sharing options...

Gunstar Posted October 18, 2011 Share Posted October 18, 2011 The fact is, my "hoarding" entails aquiring non-working Atari's for parts and/or repair. I keep only my 1200XL and "parts" for it, the rest will be repaird/refurbished and possibly upgraded and then sold. A service to the Atari community helping to keep more Atari's in working condition and available. Though the turn-around could be weeks or years, depending on my disposition to the work.

Best Elec. is where I got my 1200XL new old-stock motherboard. It was like $25 so I figured I might as well get it, the 1200's I already had were a bit long in the tooth when I got them.

Dropcheck Posted October 22, 2011 Author Share Posted October 22, 2011 After reading and re-reading the docs for the installation of USP OS I can't find any reason for the way these wires are connected the way they are. I have the doc for v1.5. Does anyone else have a different wiring scheme for another version? Quote Link to comment Share on other sites More sharing options...
