At last night's Retro Video Game gathering in Cambourne I got my #AcornAtom setup with a colour adapter. Here it is running Chuckie Egg.

Expanded my PWM experiments on the #Altair8800
I may(???) be the first to try this on such a primitive purely digital computer.
Programmed my #Altair8800 to address "Expansion Unit" register LEDs with PWM fading effects.

BASIC 2 chip installed (after straightening out the pins!)
SUPER impressed with this period correct TV on my #PSone at last weekends IRL event.
Have you seen that #Microslop advert on TV for Office #CoPilot where the pizza shop man types in (with his legs astride) "Help me bring back the $1 slice"?
... and the next shot is Excel doing its thing with lots of BOLLOX on the screen and then there's a queue of cars wanting to buy his $1 pizza!!!
What a cringe-athon extravaganza of BOLLOX!

Ran the program on a Dragon 32 emulator as I sold my actual machine.
Fill each one of these "mini marts" with concrete.

In the ZX81's native "SLOW" mode, yes. In "FAST" mode the results should be idential.

In all fairness, Thunderbird runs like treacle, even on a modern well specced PC.

Yeah, good question. My Beeb is an issue 4 (the ones infamous for buzzy speaker).
I was trying to diagnose the problem with my program not working with the command OSCLI (for adding variables to star commands) so I actually ordered BASIC 2 and also OS 1.2 but then I gathered it already had OS 1.2 installed, but as part of the MMF SD interface ROM.

I think there's a quiet revival of appreciation.

He is investing $135bn this year. Already invested $140bn in the past 3 years. Let's hope he burns it all up.

When making a program for platform benchmark comparisons it's not important to make the program as fast as possible. That's irrelevant. Just a level playing field.
I hand it to you to make an integer version of this program that will work on all the systems tested so far.

Okay, my brother found it on FaceAche (sorry about that)

I don't know. I'm asking my twin brother since he sourced it for me. Hopefully I'll update.
#ZXSpectrum experts; what was this provisional port for? Composite?
This is my 16k issue 2 model.

This is fascinating. Perhaps different territories have different options/plans. I'm in UK and our "Business Standard" package is currently without CoPilot as a sneaky add-on. I will keep a close eye on this tho.
Thank you for posting about this.

Well each platform could have optimisations catered for, but this "unified" (as much as possible) program does give each system a level playing field.
Thank you for doing this. I'll add it to the benchmarks.

Of 20 decimal places? The program prints it on the screen (but without decimal point itself).

Thank you but not that port. The one that hasn't been "cut out".

@uncleslacky @Robsonde
Yeah this test IS a test of how each micro impliments floating point BASIC program interpretation.

@JamesTDG@mastodon.world
I could do that. In fact I was going to investigate doing a composite mod at some point anyway.

Not only are this trillion dollar MEGA CORP unable to find icons to suit simple shapes, the "liquid glass" UI is making a right mess of the submenu. What have these utter NUTTERS done???

Floating point variables makes it more of a level-playing field across platforms.

Yes, I'm starting to get into its quirks. Phonems is a fascinating method of speech synthesis.

The ZX80 processed without using clock cycles on producing the display. The ZX81 (in default SLOW mode) will be much slower. And I believe it's not possible to select FAST mode on the Spectrum anyway, so the Spectrum will be similar speed.
Tho someone needs to do a test on an actual ZX81 default SLOW mode.
