I very much appreciated you making it available for the Dragon user meet here in the UK two years ago! Thankyou David!

Hello and welcome David!

It is not always busy here, but it's a lot better than facebook for ensuring resources and discussions stick around and are retrievable. Some of the older discussion threads I found absolutely fascinating when I joined here at first!

Kind regards,

Mike

Well, the TO-3 LM309 replacements arrived. IMG_20200611_170548.jpg and I (with some trepidation) took the de-soldering iron and braid to the power board on my workhorse D64.

Interesting Stew - so have you added a ear and remote socket, and made the uDW play out the cassette loadable Drivewire dweeb?

I might try to add in a drivewire column.

Phil H-S suggested a comparison between the various mass storage options available for the Dragon would be worthwhile. so I've created one.

Compiled mame 0220 the other week. Still appears to be a problem with Soren's OS9 double sided disk booting, which works fine on a real machine, on Xroar, on multiple drive emulation mass storage solutions.

Something is definitely wrong with Mame's floppy subsystem for Dragon 32/64 machines.

Interesting measurements Stew! I assume those were all bare-machine, no disk interface and on factory original 4700uFs?

The TO-3 packaged switch mode converters ... this looks like them...
