Request for more pix of Amiga connectors
« on: December 25, 2016, 02:19:36 PM »
I just had a brilliant idea. If owners of Amigas could post pix of rare / unavailable parts, that would help to create STL models of those parts, in order to repair and maintain broken machines.

(An STL is a downloadable 3D model of an object, typically used by 3D printers to make plastic components in a range of colours and materials).

That way, very rare hardware (like working A3000 PSU connectors) can be rebuilt. Indeed, the parts could be printed locally to where the repair is happening, saving on postage costs. Via a service like 3dhubs.cm

What do you all think? It would be very nice to be able to source things like A500 trapdoor panels, for instance. Or the panel for the Zorro connector on an A1000... ;)

A full plastic case is beyond the size capabilities of most 3D printers, but if we start small, who knows what people will be able to do in the future....

EDIT: I'd better start a new thread... DOH!

The customer is ALWAYS right.

They can be a lot of other things sometimes - pig ignorant, awkward, demanding, cynical and or mean.

But they are ALWAYS right. ;)

Ah yes. Here in the UK we have "caveat emptor" - "Let the Buyer Beware" - and customer service is somewhat different. For instance, the classic "Cheese Shop" Monty Python clip.

TO ANYONE COMPLAINING ABOUT SLOW SERVICE: YOU SHOULD BE LUCKY TO HAVE THIS GUY WORKING ON YOUR EQUIPMENT.

Send your repairs to UK back and forth and see how long repairs take.

Hmmm... all the more reason for me to reskill so I could offer a similar level of service for UK Amiga owners, I guess.

It's not like I'm a total repair moron, just that I was never taught to do SMD properly. About time I sorted that out, I think. Training and lots of practise on SMD circuitry should do the old fix skills a world of good.

I guess rating me to Acii, I'm about Milspec 2000 category R. Restricted access but simple fixes only . Say about 2 or more levels below him in skill rating. (There's no need to respond Acii, I'm estimating, and I might not even rate that good, really).

Oh sweet one Chief. I wish all the PSU fixes looked that great and had some extra Butch factor. PSU overfactored? No such thing, just helps keeps her steady as she goes. :)

Why not? Pin compatible chip mostly, apart from feeding the 060 version 3.3V somehow.

Could be issues with any particular board not running at full speed (040 only supported up to 40MHz so never tested faster) but it should work up to that speed and maybe faster.

Not that I am saying it is an easy thing to do. I noticed that somebody recently did a schematic of their A3640, and I think David Haynie already released the GAL source... maybe just GAL object code, but both of those help a lot with fault finding and researching better CPU card designs.
