There are a number of canned M/L PMG routines available to speed up BASIC programs.
One place to start would be Compute's First Book of Atari Graphics, chapter five.

I seem to recall a simple, limited type-in compiler in an early ANALOG or Antic. It's been years since I foolishly sold my collection, otherwise I'd be digging it out right now

I'll bookmark this thread so next time I wonder what's going on I can remember that I already know how to fix it

Could you try creating a new user account and run the flasher from that user and report if it works or not?
Creating a new Admin account (named FujiNet, of course). and downloading the x64 flasher to that account worked.
Back in my main account, running the flasher gets no response at all. The COM device is visible in Device manager (Silicon Labs CP210x USB to UART Bridge (COM3)) in my main account.
I have two 1.0 devices, both respond the same way.

Same here - I've tried the x64, the x86 and the Test versions. Tried copying it to \windows\system32 to run it from the Admin powershell, but no joy.

You forgot to notice and mention the unusual NEC dram chips with metal covers and gold pins too!
Seven of eight, with the eighth also being NEC but in the more familiar plastic.

Fantastic resource!
Two observations:
The SuperSalt manual link is giving a 404.
And you don't have DOS 3.0

By default, as I recall, no; you have to download Draco's (and then Chuck's, if you can find it) and install them in two of the OS slots.

I'd forgotten about Hohman's board. Did he ship an OS with it, and if so what was it ? I think the answer is no, he just sold the cpu card itself. I'll have to ask him about it next time I talk to him.
It's a CPU only, with a programmable logic chip inverted on the underside of the board. No OS. It did include a disk copy of MAE (65816 edition).
All the pins are gold, which is problematic if you ever pop it out of a computer. They're very soft and easily break off.

I have a bunch of 65816s, but they all run on the native OS (1200XL or 800XL).

Draco has a native 65816 OS on his site: http://drac030.krap.pl/en-specyfikacja.php Burn it in to a 27128 and swap out the XL OS.
Also has a 65816 BASIC: http://drac030.krap.pl/en-mb-zmiany.php

I have an Antonia in an 800xl and also a FTe Sweet 16 (although it's not currently installed - needs some repairs before I can reinstall it).

I need to do this. Sys-Check is probably the only thing that I'll ever have that would benefit from it, unless the external U1MB makes use of it, but it's convenient and easy enough to do. Thanks for the pictures and the link.
IDE Plus adapters also benefit from it.

Here's a (non-Atari) story about Federated Electronics in the early 1980s... apparently, their customer service needed a bit of work.

I have been on the board of volunteer / charitable organizations before, so I have great respect for those who serve and keep organizations running.
(And my German consists of "Zwei große biere, bitte fraulein", so at least I'll remain hydrated..)

Memory is accessed in 16K banks at $4000-7FFF, controlled through PORTB. The 130xe banking permits separate CPU/ANTIC bank access; some third part upgrades do not.
If you program for current versions of SpartaDOS X, you can make system calls within your program to request expanded RAM and be less concerned about banking.
...of course, the original 800 uses an entirely different banking scheme for expanded RAM...

32-bit ranges wouldn't work well on an 8-bit computer.
Clearly you need to upgrade your 800xl with a 65816

Might also be worth asking @bob1200xl what he's got hidden away...

@VinsCool In the old days my friends and i use to go to mtl just to go clubbing lol. Friends of ours that had gone to school there got us into it. This one club we used to go to had a roof top patio very very very high up
Club 747 at Place Ville Marie?
I was partial to the patio at Café Frappé on St Laurent, with gin and tonic by the pitcher.

In Atari BASIC, as I recall, you can't READ directly into an array. Try
40 READ X
45 A(B,C)=X

While we're discussing the Express Cartridge, what kind of cartridge was used? Was it an OSS (bank-switching) Supercart or something else such as a regular 16K eprom cart? I used the disk version years ago but switched to Bobterm, so I don't recall much about Express.
It's a stackable ICD cart, with a custom GAL, like SDX and Diamond.

Apparently screen matrix is located to $0400. I don't know what is the default is on the A8 side, if there even is a default.
Atari does not have a default screen area; ANTIC lets you point the screen anywhere in RAM. On the 130xe and compatible upgrades, you can point the screen to expanded memory while running programs in main memory.

Who has source for these? Are they your apps? Will you release the source up to Github? that would be very helpful I'm sure.
I put together CardStax many, many years ago; all Atari BASIC with some canned ML routines. Please feel free to rip it apart and improve.

Sound file header, what should be in it?
in Atari 8-Bit Computers
Posted
I'd want to use
D200as the first four bytes of the header... but I guess all sounds aren't necessarily POKEY any more...
