“No” doesn’t make line go up. 🤷‍♂️ 😩

Haha, ASM in a nutshell. 😂

Oh, yikes. 😅

Sorry, hard to fit in one toot! I mean to say thats the only approach I’ve seen. Are you trying to preserve the stack, or examine the contents, or something else?
November 12, 2025 at 8:21 AM
Hmm! For a given system you can assume which page/section of memory it’s in. Stash it somewhere safe, do your own stack elsewhere and restore after you’re done, but don’t bother to examine it. If you are preserving it to return to the OS, there are probably sys vars to worry about too, anyway, etc.

I *think* it’s using a loop to adjust the stereo position, and the envelope is chopping the noise into separate “chuffs” (so to speak!)

Tonight’s homework: get my head around how to use the envelope controllers (i.e. understand how that steam train sound is made!)

I'm sure I will! I've heard the Spectrum forum nerds might be partial to a type-in or two so I've mentioned it over there as well.

I've been looking forward to this! I've bought one for me, and one as a chrimbo pressie for my pal. Such a great idea, well done.

Ace, me too!

Adapted from the SAM Coupé user manual. It’s actually a demonstration of SAM BASIC’s SOUND command, but we can replicate that in Sinclair BASIC with a couple of OUTs to tweak the appropriate address and data ports for the SAA1099P sound device.

Looks like they stock some fine records in there too. My favourite label in the 90s!

Gorgeous. I think I had a shell suit in those exact colours!
