I am working on a very corroded beige unit. I soaked the parts in citric acid solution to remove the rust am am now testing each part, starting with the power supply. The 12 and minus 5 volt rails seem fine, but the plus 5 volt rail takes about 30 seconds to come up and then stabilizes at 5.207 volts. This doesn’t seem correct. Unfortunately, TI used a complicated circuit for the plus 5 volt rail instead of a 7805. Anyone here willing to help me troubleshoot?

Hello, I picked up an Atari 800XL a few months back and will soon start to enjoy it. I understand that they came with BASIC revision B and later Atari models had a less buggy version called revision C. To upgrade the 800XL, are the two options (1) buy a revision C cartridge or (2) upgrade the BASIC ROM? For option 2, would I just buy something like this off of eBay? https://www.ebay.com/itm/162564860327?ul_noapp=true I do have a EPROM burner so is another option to find revision C online and burn it to EPROM? In either case, is it a matter of popping out revision B ROM and putting in revision C? (assuming the ROMs are socketed.) Thanks

so i have been thinking about this and was looking as one does, and i came across this on ebay http://www.ebay.co.uk/itm/AC-DC-5V-1A-1000mA-Power-Supply-Buck-Converter-Step-Down-Module-Small-Size-/191879043673?hash=item2cace1da59:g:tpUAAOSweW5VeVqx I did try and do something similar with a hefty heatsink and a load of voltage regulators and capacitors once but I got some image distortion during my tests so abandoned that idea, what I want to know if anyone can help is would this deliver power clean enough to run a Colecovision without any image distortion it maybe worth getting one just to try at that price but wanted to see what others thought first

Booting the Falcon's internal hard drive
Justin Payne posted a topic in Atari ST/TT/Falcon Computers
Hey all, I decided to drag out my ol' Falcon to do a little C programming on it. In addition to the internal hard drive, it also has an external SCSI one. I booted it up the other day and the hard drives were there and accessible. After pulling out a ton of floppies to see what I had, I noticed that the falcon wasn't showing the hard drives and appears to be booting to the default desktop. I'm assuming that either I need driver disks at boot time in the floppy, the drivers on the hard drive got corrupted, or the drive itself went end up on me. I found a bunch of system disks for the Falcon but none said, "Hard Drive disk" and the Falcon manual I have doesn't really say that I need drivers. So, instead of a bunch of trial and error, I thought I seek advice. Any ideas what the issue is and how best to resolve it? I really don't care about what's on the disk since it seem that most software is available for it online.- 17 replies
