TheDash Posted January 25, 2018 Share Posted January 25, 2018 I've given up on getting a replacement psu for the Dragon. Unless anyone can give me a quick pointer right now. Question - has anyone 'made' a power supply for this odd 8bit voltage consumer? It needs at least 2 inputs of 8.5vAC and 28(!)vAC, at 1.5a and 250ma - pinned in via a 9pin D type or 'Atari joystick' connector. I'm very close now to wiring in as many individual transformers as it takes - and maleesh the condy's**. Unless anyone has a better idea? ** excuse the Australian Army slang.

MarkO Posted January 29, 2018 Share Posted January 29, 2018 IIRC, Dragon 32s were only available in the UK.. Have you contacted any of the UK Dragon user about a spare Power Supply or Work Arounds??? There is a Facebook Group and a forum at World of Dragon... MarkO Quote Link to comment Share on other sites More sharing options...
Quickie Posted May 17, 2018 Share Posted May 17, 2018 (edited) IIRC, Dragon 32s were only available in the UK..

MarkO What a pitty that nowadays some classic computer groups are using Facebook instead a forum. I hate Facebook, but I found it specially annoying for topics or hobbies like retrocomputing. Anyway, fortunately enough there is a relatively easy way to build a Dragon32 psu detailed on a public website -> http://archive.worldofdragon.org/index.php?title=Replacement_power_supply_unit In essence is just wiring a toroidal transformer to the proper DB9 Dragon32 PSU pinout and to 220V. The problem is that this implies some work (create a box to acommodate the transformer + wiring) and it isn't cheap at all. Hope having helped. I'm in the exact same situation and I will finally go for a toroid transformer as my Dragon PSU PT 48290 is giving just 4,5VAC on both SEC I and II Haven't tried yet to open the PSU, but I don't want to break it (it's sealed with some metal clips).

ColorComputerStore Posted June 3, 2018 Share Posted June 3, 2018 Wonder if you can get specs of Tank Dragon and base a new schematic on that. Quote Link to comment Share on other sites More sharing options...
