Re: New version of Scramble for the beeb (going well)

That is correct, four copies of four pixels per pair, I think my maps end up with 30 pairs which fits nicely into four pages. Same clipping, mostly for the sprites, but also to keep things simpler (apart from those trixy masters). You can see it in the early video before hiding the sides. I only hav...

Re: Atom Speed test

If it is very small, could you wait for vsync, run the test and count cycles until the next vsync?

Or if it is just hw, count cycles between vsyncs.

Re: New version of Scramble for the beeb (going well)

I had also forgotten about the sound.
During play, the three tone channels are used for the engine noise (womwom), the bomb (descending) and shouting (dumdum) while noise is used for explosions, so can also be used for whistling when not exploding.

Re: New version of Scramble for the beeb (going well)

I will try and write it up, but it won't be as good as pop. For now: The scrolling is similar to what I described in the smb thread. I was asked about collision detection, and here is what I said. For scramble, I check the character address of the shot/bomb against the character addresses of the roc...

Re: Some game not displaying and not working

If you have a DFS loaded, ~PAGE is probably at &1900, but tape games often expect it to be at &E00.
Try:

Code: Select all

*TAPE
PAGE=&E00
CH.""
I'm sure someone will be along to correct me ;)

EDIT: *TV100 just seems wrong!

Re: Quick measurement

As I had a DB15 to hand, I just had a quick check of my "to hand" machines and the issue 3 has the same reading as above, while the issue 7 and master both have 0.96x kOhms in both directions.
Caveat, my battery is low in my meter!

I bought it off its original owner and haven't touched it, other than to give it a bit of a clean, works nicely, if a little toasty.

Re: Restoring an Issue 2 Model B to Original State

Is that the original PSU?
If not, it will probably run cooler anyway.
Which machines had the OS in 4 chips and basic in the os socket?
Probably not worth changing that either.
I lost quite a bit of code to os0.1 bitd.

I would prefer to sell ready made as I can test first, but can be flexible about cases and cables. If people want parts, I can do that, but untested. I'd like to get ...

several USB sticks/card in adapters
I'm not bothered about updating, only that as it doesn't seem to see any disc images, it was a way of testing that the USB stick/card could be read.

I can't believe that both units (from different resellers) have USB faults.
