WANTED: ST(M) badge.

During the process of retro-brightening my original 520STM's top case, which was a deep orange colour, the paint on the badge has lifted off and washed away. It's very nice and shiny now but no-longer says "Atari", so I'm looking for a replacement. I'm guessing that the STF(M) case badge is probably...

Trying to identify RAM upgrade.

I had a 2MB RAM upgrade fitted by Third Coast Technologies to my 520STM back in 1989 and I would like to identify the manufacturer and determine just what I need to do (other than populate the other half of the board with 1Mbx1 chips) to bring the machine up to 4MB. There don't look to be any jumper...

Re: 68040 machine

You can choose from a variety of C compilers for Mac OS or UNIX, you don’t have to use Apple’s. And there is no “Apple version of C”, this is plain ANSI C or C++. Dont they mainly use Objective C on Macs? Not really, that originated from NeXT and hence is MacOS X and later. (MacOS X, or macOS as it...

Re: Going Gotek - FlashFloppy How To

Flashfloppy doesn't require any manager programs/firmware on the stick, merely an empty drive with a text file called ff.cfg to set the configuration. You then merely put disk images on the drive. If jumper JC is left open then the drive will auto configure to shugart and you won't need a ff.cfg fil...

Re: Credit card vs Debit cards on new webstore poll

I always use a credit card for on-line orders due to the extra protection from the consumer credit act plus it doesn’t allow direct access to my bank account, mitigating the potential hazard of the card details being leaked.

Re: Going Gotek - FlashFloppy How To

I’ve never seen this “manager”, that must be a FF v2.x feature. Isn’t the v2.x firmware still in alpha/beta test status and unstable?

I would suggest changing to the v1.x firmware for the time being as that doesn’t try to run anything on the host system.

Re: Importance of clean fans

Oh, those Dell Precision workstation CPU trays are a disaster. The square blocks of pins in the connectors onto the motherboard just stop working after a while. The next generation (7600 series) did away with all that thankfully.

I expect the combination of colourant, plasticiser and flame retardant also affects the rate and depth of browning too.
Indeed. The more opaque the colour the less penetration.

Re: Plastic yellowing: Light + heat?

You're probably correct that it's any UV exposure and it depends very much on the chemical composition of the additives to the plastic. "Leech out", however, isn't the correct idea though. Basically the bromine is part of a molecule (colourless) which gets broken down releasing molecular bromine (br...
