Oge Posted July 20, 2011 Share Posted July 20, 2011 I have read here the Power Pinout for a 800XL and I would like to ask two questions: 1) Is the pinout viewed from soldering side? 2) Is it truly compatible with all the XL/XE range excepting 400/800/1200XL? Thanks in advance, Oge Quote Link to comment Share on other sites More sharing options...

Fox-1 / mnx Posted July 21, 2011 Share Posted July 21, 2011 I have read here the Power Pinout for a 800XL and I would like to ask two questions: 1) Is the pinout viewed from soldering side? I placed this at the top of the page: pins numbered as when looking to the chassis built in the peripheral and when clicking it it'll show you this: Can't make it more clear. 2) Is it truly compatible with all the XL/XE range excepting 400/800/1200XL? The pin-outs... yes. Quote Link to comment Share on other sites More sharing options...

Timbit Posted March 26, 2015 Share Posted March 26, 2015 Pardon my electronics ignorance, but why are there three +5V and GNDs? Are they all isolated for some reason? Do they each have their own amperage, and if so, what is the benefit of that? Quote Link to comment Share on other sites More sharing options...

Van Posted March 28, 2015 Share Posted March 28, 2015 They are all connected to the same supply, not three separate supplies. Basically, each pin would carry only 1/3 of the current... While true, seems unnecessary They could of just as easily used a two pin connector. May have been an Industry or Atari 'standard' back then to use DIN for DC connectors as I have seen other vintage gear with 2 pin DIN connectors. Today the coaxial power connector is common due to size mainly. Yogi Quote Link to comment Share on other sites More sharing options...
pusakat Posted February 8, 2020 Share Posted February 8, 2020 For the voltage range, will a +5.2V output PSU fry my Atari 800XL? Quote Link to comment Share on other sites More sharing options...
Rybags Posted February 8, 2020 Share Posted February 8, 2020 You'll often get a higher voltage when no load is present. Not sure what mine measured, might have been around 5.1 A symptom of overvoltage to the point where damage is possible can be constant audio hum.

The reason I'm asking is I recently got an 800XL without cables and stuff for cheap, but just the base unit. I'm checking if any of my existing power supplies (for phones or other electronic gadgets) might suffice as a substitute PSU. I think all I would need is a 7-pin DIN connector and wire/solder it properly to the PSU output and it should work, right? Power outlets here in the Philippines are 220V/60Hz. Shipping costs make it economically crazy to buy a PSU from overseas. I'm trying to cobble together cables and the power supply myself to keep costs down.

Rybags Posted February 8, 2020 Share Posted February 8, 2020 A 1.5 Amp USB charger might be a good choice - then you just have to attach the DIN plug to a USB cable, e.g. salvage one from an old keyboard or something. You only need to solder 2 pins on the PS plug, they went overkill with the choice for that one. Quote Link to comment Share on other sites More sharing options...

Rybags Posted February 8, 2020 Share Posted February 8, 2020 Should be - the amperage rating is what it's capable of supplying, the Atari's demand should be under an amp without additional stuff attached that draws more current. 1 Quote Link to comment Share on other sites More sharing options...

The voltage tolerance of +5VDC chips is 5%, up to +5.25V is within tolerance. 1 Quote Link to comment Share on other sites More sharing options...
pusakat Posted February 10, 2020 Share Posted February 10, 2020 Would a PSU for an Atari 65XE work with the 800XL? I'm too lazy to google and wade through the answers right now. From what I've read so far, the 65XE PSUs output +5v at 1.0A whereas the 800XL PSUs output +5v at 1.5A. Is this right? Will there be any overheating issues? Limitations on upgrades, etc.?

ivop Posted February 10, 2020 Share Posted February 10, 2020 5V/1A should be enough for an 800XL, but as you indicate, there might be limitations on upgrades that pull too much current. 1 Quote Link to comment Share on other sites More sharing options...
