Sorry to necrobump this, but is this disassembly or the one for BlackBelt still available somewhere?

That's a fine question.  I'll have to do some digging, or redo it from scratch.

[Thoughts About the Atari 1400XL & 1450XLD]

I think a model with a built in disk drive would have been a good thing to have, but the 1400XL seems unnecessary

Yes or no, depending on what hardware you had already.  And how much of a budget you had at the time.

[ftp.pigwa.net needs your help]

A relatively recent and still experimental protocol named IPFS has come about.  https://ipfs.io/  It seems especially well-suited for archival purposes and data that does not change very often.

 

As a little experiment, I dumped all of the files out of the fujiology_archive_v1_0.iso into IPFS.  They are now visible through the following link, at least for as long as I host them.

 

https://ipfs.io/ipfs/QmUc6my8cJNiF8AGjVjPtyu47iAu2ohT5oDUecUGGbYuir

 

Perhaps we could look at using this to mirror other archives to reduce bandwidth use and network strain?

[1090XL remake]

I'm curious if they could be used with the 14xx Voice, Speech or floppy as they are parallel devices.

I think that might be part of the reason the 1090XL only had five slots.  If there were up to three devices on board the system (like there would be on a 1450XLD), then this would avoid conflicts.

Thank you for taking the time to explain these oddities and nuances.  I really enjoy reading about them.

Might also be that loading down low at $600 won't work.  Certainly can't do that with any of the 100 or so DOSes we have on the system.

The bulk of it starts at $6000.  For whatever reason, there's just this stub at $0600:

 

[0002] Block:  0600-0608 (0009)
0600  4C 07 60    JMP   $6007

And a few other non-code bytes I omitted.

[Help running Atari 800 terminal emulator from MIT]

So just from a cursory glance of the binary file, it looks like there's no part of the file to set RUNAD ($02E0) to 0600, so the binary gets loaded in to memory, but not executed.

 

Also it's been a long time since I've looked at atari100, so I'm not 100% sure it will directly load a DOS file directly without a DOS disk image loaded first.

Another problem is getting the original build tools to work.

Can you tell us a little more about them?  Since they're of little interest to all but a few people would you have any problem releasing them?

This thread is already 50 pages long - might it it be worthwhile to start a dedicated FujiNet testing thread so there’s one place for people to post results along with the example ATRs for each issue? 

Obviously this is up to the developers' preference, but you could use github to track issues: https://github.com/FujiNetWIFI/fujinet-platformio/issues

"between 9:30am and 1:30pm" Wow you got the deluxe service or something -- mine just says "by 7:45 pm".  Still, it got bumped up a day, so I'm not complaining.

[For the programmers...]

In sixth grade, I wrote an Atari BASIC program to give me remainders from division problems rather than decimal answers.

Obviously not particularly intricate, but awfully handy at the time.

[Strange TypoII behavior]

It sounds like Typo II is getting LISTed to disk along with the actual program.

From https://www.atarimagazines.com/v3n9/TYPOII.html

"To remove TYPO II from your program: Type LIST "D:FILENAME",0,31999 (Cassette owners LIST "C:",0,31999).  Type NEW, then ENTER "D:FILENAME" (ENTER "C:" for cassettes).  Your program is now in memory without TYPO II and can be SAVED or LISTed to disk or cassette."

[Altirra 3.90 released]

I think I found a bug in the Altirra OS ROM.  If I run the attached program with either Altirra BASIC or Atari BASIC rev C and Altirra OS, the printed value of pi is off by one digit in several places.  If I run it with OS Rev 3, it is correct.

 

The proper value is 3.1415926535897932384...

This would be a good solution except that I haven't exposed PBI IRQs to custom devices yet.

D'oh!  I should read the docs more closely.

Custom devices can interface to a local network server but don't currently have the ability to access the full memory map, they can only affect their own local device memory. 

This is probably a rather heavyweight solution, but you could make a PBI driver that services a PBI interrupt and then reads/writes whatever memory you want, right?

It's possible I'm in the minority on this, but an extra second or two on the initial boot screen would be nice.
