Re: 3D Printing

That actually looks dodgy as heck. Good thing you spot it. I'm also looking for some sort of a good deal when it comes to bang for the buck. My kid wants a 3D printer for Christmas. I'm totally pushing him in that direction anyway because I want to play with it as well. haha It *IS* a total scam. T...

Re: Gold BBC Micro

A little off topic(ish), but while I was working for Oki we had two Microline dot matrix printers marking particular sales. One was silver plated, the other gold plated.

I'm just wondering, and this is something I've been meaning to try for ages but never seem to get round to :oops: :shock: , but has anyone ever tried hooking up a SCSI DAT drive for backup purposes?

Re: Master 128 start up in error message: “Over 0 marks”

Sydney is bang on the money. The text you see is from the built in Editor ROM which says the LANGUAGE ROM (as shown by *STATUS under LANG) is set to 11 instead of 12. Another way would be, while it is still showing "Over 0 marks", press F1 to give you a "*" command prompt at the bottom of the screen...

Re: Star LC-10 dot matrix printer

Different advice for the rarer dot matrix printers with the square pins: They should only be used with film-based cartridges and not ink/fabric cartridges. They are dry and have no oil lubricants. Adding oil can cause them to jam up. Using fabric cartridges can cause the ink to jam them. Some print...

Re: Star LC-10 dot matrix printer

Actually most dot-matrix printers use/used the ribbon to lubricate the print head needles - at least with the genuine ribbons where the head lubricant is part of the ink formulation. Of course on a printer which has been dormant for a considerable period of time a little WD40 will help. Once given a...

Re: BBC B: replacing PSU capacitors, general questions

I suppose an important question is - what screwdrivers do you have? An oft made mistake is confusing pozidrive and Philips screwdrivers, which are NOT the same and not 100% interchangeable.

Re: Pretend your BBC is broken

Would viewing via the RF-out defeat the load borne by the screen? As I understand it, the CUB takes the strain of mode changes. But if the signal hits the modulator first, will the BBC's own hardware be the shock absorber before the signal even hits the TV? In a word - no. It is the display device ...
