Re: CO700115 with Piggyback RAM expansion.

I can't quite make out the revision, I will update when I have it apart again, but it has a piggyback RAM expansion. Anybody else think those wires look like telephone cable? Very very early motherboard - no filters. And yes, that's typical extracted wires from a telephone extension - I've used the...

I will update when I get a chance to give it the once over and power it up.

Anybody else think those wires look like telephone cable?

Re: 520ST small model w/ no floppy / general advice

I have just received an original 520ST from exxos, which apparently has piggybacked RAM, though not currently running. I will pull apart later and have a look.

Re: Is this true ?

I had this pop up when I went to YouTube last night.

Not only that, I've run into it before and emailed my MEP about it and got a fairly sane response too, saying a number of complaints had been had about it.

Re: Soldering Irons

My favourite is the old Maplin one on the left, it may take a few minutes to heat up, but it's so consistent, I just know it will do what I ask of it. I've actually got the same one! Mine stopped getting hot.. so brought a new iron, then it still didn't seem to be getting hot enough to melt solder....

My Stuff: Hot_Stuff.jpg My favourite is the old Maplin one on the left, it may take a few minutes to heat up, but it's so consistent, I just know it will do what I ask of it. The big black job does have an iron, but TBH I use it mostly for hot air stuff as it's a bit big for my workbench (Desk!). Ok...

I hope the replacement serves you well :)

Re: Floppy Support

Just as a little bit of extra info, these print fine at .2mm, but at .1mm had some very fine stringing, and I know that exxos also had some print problems including stringing too. .2mm is fine for most scenarios, but if you try to print finer and get stringing, then dropping the filament temp should...
