Re: Which soldering iron?

+1 for the Hakko FX-888. It's the best iron I have ever used. I do have a small Antec that is about a million years old and just had a new tip, but it's banished to the garage now I have the Hakko. Well out of your price range, but you will find yourself doing a lot more soldering of a much better q...

Re: Today I received.....

Comparing it with an orchid is novel, if a rather spurious, though - although talking about "its basic adequacy" isn't really bigging it up much.

Nice gadget!

Re: "Unfixable bug" in BBC B Elite

Incidentally, this is quite different from the huge box PC games in the 1990s, such as Descent, Doom, Duke Nukem 3D, all mostly empty! And these do feel a bit like getting not much value for your money: Hey, the box is mostly empty! That's true - but I think (at least in the case of Doom) that the ...

Sorry, thickie question here - I didn't know what the Torch Graduate is so headed over to Chris's Acorns. Do I take it it is a co-processor that implements a sort of "PC in a box" that uses the Beeb as a keyboard / display?

The WAV file is 7 minutes long! I'm thinking I can use this as a sort of soak test to see if all's well . [edit: ...

Looks like a Spitfire to me. Stukas had a sort of bend in each wing so they were vaguely W shaped.

Re: Bladerunner 2049

Yes, it did have some of the atmosphere of the original, but it was disappointingly shallow and predictable. A cynical remake to rake some cash in. I did enjoy it, but I fear it will not become a "classic" like the original. It's like Alien Resurrection vs Alien.

To make further progress with this machine we must start to look at the disk drive.

Whilst waiting for some 18 pin DIL sockets to arrive, I thought I'd renew some of the tantalum capacitors; in particular the two that had gone closed circuit.

Re: Epson HX20 - first laptop !EVER! 1981+

By the looks of it I'd suggest that "CM6000" is a rebadged HX-20. The keyboard surround looks very aftermarket. HX-20 is one of the first machines I wrote code for professionally.. I recall it had a nice keyboard and a tiny little screen (too small for BASIC but otherwise readable). I keep...

Hi KayJay and welcome to StartDot! To answer your question... the BBC is a 6502 machine, as I am sure you know. If you want to use it for Z80 coding you will need a Z80 co-processor. Probably the easiest/cheapest way to achieve this is to get one of Hoglet's matchbox co-processors. It is discussed a...

Ok, I think I've tracked the video noise down to the 2114 video RAM. The flickering vanishes when you heat the chips up with a hairdryer! And stays gone. Applying freeze spray doesn't make it return, which is odd. Might try some nearby chips too, just to be sure. Meanwhile, I made progress with the ...

WTB 6 x 2114 SRAM

Hi

Anyone got some 2114s spare? I need 6 for my Exidy Sorcerer, which seems to have failing SRAM (doesn't work until warmed up). If you have fewer that's fine, I can swap them about until I find the faulty piece.

Cheers
