Re: Portable Puzzle Collection

Recently I've got into Tents, Towers, and Tracks - that's in increasing order of 'reward' Ah, Towers. Some randomly generated grids are fairly easy to solve but now and again there's one that provides extra head scratching for a while. I have played Tracks too, but not so much Tents. There are some...

When I first started using Zoom I noticed that my webcam video was being mirrored rather than being seen in the normal orientation. Within Zoom there is an option to change this if you prefer. For example, if you were wearing a t-shirt with the Acorn owl logo on it, you'd want it to be facing the r...

Seeing as there are a few spaces left, I'd like to attend. As last time, I may be doing a spot of DIY or whatever that day, so likely will dip in and out (and I could turn off video if I do disappear for too long). I'll be taking part in another zoom gathering between 10am to 11am (but I could show ...

Re: Portable Puzzle Collection

The puzzles are a wonderful way to spend time.

I mostly play Pearl, Loopy, Net, Galaxies, Map, Unequal, and Slant, but do dip in and out of others as and when I'm in the mood. Such a variety.

Re: Monitors compatible for the BBC micro

It is possible to convert some that have TTL RGB inputs to accept analogue RGB inputs. Mark IIRC,it was just some jumpers that needed switching. Yes, that's pretty much it. I was fortunate enough to get one with those jumpers and I connected the jumper pins to a switch that I fitted on the back of ...

Re: Monitors compatible for the BBC micro

To add a few thoughts, back in the day I had a small 9" colour TV with SCART input on the back and I had my Beeb's RGB output connected to that. If I wanted a larger screen display I plugged the Beeb into my 22" Grundig TV via the aerial socket which gave an OK picture, but not what I'd call a fanta...

Re: Creating a !BOOT file

One thing to watch out for when EXECing a !BOOT file is that the file is left open when the BASIC program CHAINs. Mostly this will not be an issue unless the program does a lot of data file accessing. BASIC can only have 5 simultaneous files open at one time and will crash due to the !BOOT file sti...

Not easily, unless you want to use the BASIC OPENIN, OPENUP, CLOSE etc. commands and write yourself a text file editor.

Install a ROM such as VIEW and you can load that to edit your !BOOT file.

Sideways RAM expansion

I was thinking about the use of RAM in the Sideways ROM area and I wonder if it was possible somehow to have a large paged RAM area at this location?
