Re: Capacitors

In Bill Lumbergh’s voice, “Yeah . . . Um . . . I’m gonna have to go ahead and sort of disagree with you there, Mark.” An 18-watt soldering iron is not going to be enough on its own, especially on thicker tracks/leads. With good technique, I’d opt for a higher-wattage iron—it melts the solder faster,...

Re: Need some help hiding the OK output.

I selected the HQ version for screen shots. I think that is what makes it look a little weird. Yes, Fuse basically has a couple of simple interpolation filters. I think they’re there just because . . . someone at some point decided he could throw a few coding skills at it. I normally use the PAL TV...

Re: Need some help hiding the OK output.

Very neat looking graphics! One small suggestion, though. Avoid using any special “smoothing” filters on the video output. They may look cool on your computer screen, but they take away from your design decisions, when every pixel counts. If you can, either try enabling some filters that approximate...

Re: Capacitors

There is nothing linear about the Sinclair PSU. Technically, you’re right. Back in the day, I always either installed a voltage regulator inside a transformer PSU, or assumed that it will be present in the circuit of a piece of equipment. When switched-mode PSUs came along, I referred to the tradit...

Re: Capacitors

What are the risks of running this machine using the original 1980's capacitors? If I invest 60-70 quid on an IDE/MMC device, do the old capacitors pose a real risk to damaging the add-on? The main risk that an old capacitor might develop a short, which in turn might ruin a few ICs. It’s generally ...

Re: Moving a 2x2 pixel 'ball' around the screen

The standard method of converting the horizontal coordinate into a screen address + number of shifts applies: ;B holds the x coordinate ;HL holds the screen address of line start ld a,b ;x coord: five highest bits=column (0-31), rra ;we need to shift them into the lowest five bits rra rra and %00011...

Thanks. It was 'Write' rather than 'save as', but that was very useful. Thanks
No problem! (I’m on a Mac, and Fuse is a standalone app, rather than a direct port. Some menus might have different names.)

Re: Saving to virtual tapes in Fuse

Mmm. Not sure what your goal is. Fuse can either save raw data, or create a standard tape file. For the latter, you do need to select the “Use tape traps” option. Then, use the standard ROM save routine (say, via BASIC), and then select “Save As” from the Media menu. Note that Fuse will append data ...

Re: Saving to virtual tapes in Fuse

Turn off all tape accelerator options.
