Re: More from the attic . . . Sinclair ZX Spectrum +

Post please, I will PM you to confirm address.

I'd have loved to pick up at ABUG, but could not get a pass this time round :(

Re: YARRB [SOLD OUT]

The fix might be as simple as adding a small capacitor (50-100pF), or a small series resistor (30-100R), or both. Dave, Short version: We both came to the same solution and for people in a hurry: this works \:D/ Long version: I remembered this article in Atom News (sorry, only in Dutch) about refle...

If I remove the AtomSID the copro works again perfectly. I wa...

Re: Atom upgrade options

I'm working my way slowly through the list :)

The Atom SID is good fun, and my next add-on is a Co-Pro via the Atom TUBE I/F

I have a spare board of each if you're interested.


Having said that I went for a the Colour/HDMI I/F, Noisekiller and a Memory Expansion before the above.

Re: Replacing the Tube connector on a Master

Least destructive method I've used for old boards is solder braid. I'd cut away the connector as suggested above then add more solder to the remains of each pin where they enter the board, once the braid starts to wick up the solder it creates a lovely clean hole, allowing the remnant to be dropped/...

Dear All,

I'm looking for an intact, empty Acorn ATOM plastic case.

Does not need keyboard surround or any other trim but should be clean/cleanable to restore original colour.
