Re: Bit of fun - One change only

In a recently posted PDF, in an interview with Kenneth Baker, it was said that the government would pay half the price of one computer if schools could pay the rest - so long as they didn't already have one: I do recall our Primary's was our first machine, I can remember well the wheeled trolley it...

Re: Bit of fun - One change only

Would those changes have pushed the prices up? Schools needed enough cash incentive to splash out on a BBC as it was. I can just about (if I'm correct, I was not very old then!) some kind of fund raising to get a BBC in the first place at our primary, or perhaps it was some extra monies as I think ...

Re: Last Gasp for the 8271

Are not most software titles compatible with the 177x series of controller ? They seem to function just fine with the 5.25 floppies. At least for me although I don't own a working 5.25 drive anymore, then again I only have a couple of discs in that size and have images of them. I think perhaps the r...

Re: BBC B+ thinks it's a BBC A?

Would one of the disc based memory testers be worth running perhaps ?

I'm thinking here the OS may not have a "16K" string in it to display that, despite it possibly thinking it, so it may not be able to say lower than 64K ?

Re: "3D" triangles/patterns (BBC BASIC)

I like that. :)

Suggestions:

1. Offer an option to disable sound maybe ? I simply REM'ed out line 345 to silence it!
2. Perhaps a random choice of colours could be picked and cycled after x minutes ? Or maybe during 'draw' itself perhaps.

Its very good though all in all.

Before I even looked at the listing (when I read the topic title) I'd assumed it was going to either be random placement/removal of asterisks in Mode2 or Mode7 or perhaps a few UDG's (user defined graphics) of the same in a graphics mode.

I was very pleasantly surprised by what I found instead. =D>

The relay on/off is likely normal.
