Hello all,

Many years ago i purchased a gas soldering iron from RS which had interchangeable heads; one of these heads was described as a hot gas nozzle for heat shrink etc.

With this item, a good solder paste and much care I managed to remove and replace surface mount ICs (not for the faint hearted); replacing simple components was easy, it was not removing the components next to them that was difficult.

The trick is not to unsolder with the heat gun! but cut out the component that you are replacing (who needs a faulty component!)
I find a scalpel will cut through processor legs with ease and then the legs can be removed with an iron, by just brushing them.
If you want to go into replacing surface mount stuff the real way then this http://cgi.ebay.co.uk/PACE-PRC-2000-SOLD...#ht_4262wt_1139
is a bargain! best type i have ever used.

That looks like a nice piece of kit, Scott.

Pity that it's not an auction (rather than a BIN* deal), then I would have had a punt at it!

It seems that Aoyue is one of the "names" for this sort of thing.

It's not been snapped up yet, I notice, Scott.

110 volts working, by the way.

I see that the seller has a nice line in electronic components as well.

How about this one, for example?

I had no idea that people collect processors!

saying that i have 100 27c256 eproms on there at the moment and a couple of hundred 86000cpu's too!

I hear that one of the very first Apple computers is to be sold at Christies tomorrow.

The Apple-1 is said to be one of the 200 or so hand-built by Steve Wozniak (with help - or moral support, whatever - from his mate Steve Jobs).

It would have been without casing, power supply, keyboard or monitor ... but it did come with a pre-assembled motherboard (which was considered a major step forward at the time).

The computer is expected to sell for between £100,000 and £150,000. It would have been sold for $666.66 in the summer of 1976.

Is that one you made earlier, Huw?

Nice "then and now(ish)" shots of Steve & Steve, though, eh?

Note as well that it is the second photo in the piece that shows what is actually up for grabs. Fancy having a punt at it?

if you want a cheapy rework station I use one of these, does the job well enough and does not risk waving scapels near fine tracks trying to cut legs off. I remove and replace with this.

Interesting.

Which accessories did you go for ... or did you take them all?
