I'm making archival copies (ATX where possible) of my original disks, and I'm finding many early titles that won't execute properly.  Since these were from the 800 days, some of this may be because of the OS rather than bad disks. 

 

Is there a list of commercial titles that require the 800 OS -- and -- what is the most compatible 800 OS?  I've always thought that the Omniview OS was quite compatible, but maybe there are other good ones?

 

Thanks,

Larry

I concur, the XL Omniview OS is +95% compatible,

You can always try the Atari Translator disks for a software only option.

 

I found Omniview was good, but also used BOSS XL a lot BITD.

 

I've also seen some others like 'FIXXL' which I think was from CSS, and OldRunner which I think was a European creation? 

 

Also saw "The Emulator" doing a quick search just now: http://atariage.com/...ions/?p=1824732

 

Edit: found downloads for disk based Translator A, B, and Fix XL Disks, OS ROM dumps for "OldRunner" and "XL Fix", as well as (never seen this before) a replacement ROM for the original SDX cartridge: https://sites.google...ataritranslator

Hi,

I seem to recall that back in the day, some titles would work ok with one translator, while other titles would require a different translator. So, if a particular title fails with one translator, it's worth trying another one (or several) before giving up on the disk.

Also, you might want to do the preservation to ATX before testing, as a dump of a marginal disk is best done as early as possible. Also worth keeping the disk drive open and keeping the drive head as clean as possible (isopropyl alcohol), I remember when I started back on the 8 bit my 1050 stopped reading disks almost immediately due to the disk head getting coated with magnetic media.

How are you converting disks to ATX, btw?

RespeQt 4.3 using both Happy and Super Archiver. I love getting these disks archived to images. Hopefully I can get them archived by summer.

If all I am looking for is OSb compatibility, is there any advantage to using Omniview or Omnimon with my U1MB vs simply switching to OSb when needed? Right now I have Supermon loaded into one of its slots but I've found that some OSb compliant programs cannot use both Supermon and onboard BASIC at the same time. Mostly I just use real OSb and a BASIC cartridge for the times that I need this combo. Would one of the Omni* OSs fair better?

Yes.  The Omniview is highly OSb compatible, but is a true 64K OS and it will run 64K programs.  The 80 column feature is nice and it has the Fast Math floating point routines.

I have a number of different versions of Omnimon and Omniview Operating Systems available.  Which would you most recommend?  Omniview XE?

Of those, I would probably pick OmniView XE.. But check the CRC32 of the one you have, there are different versions floating around:

 

  • CEC9CA43 - The one I've had installed on my 320XE since the early 90's. Works great. No idea if it has any OS based RAMdisk function, never used it if it does.
  • E4BF5B98 - Found this on the net, seems functionally identical to the above one from my testing... Interested to know if anyone knows what's different.
  • 5E908DB4 - I found pre-installed on my AtariMax 32-in-1 called "OmniView 80" in the menu selection, but identifies itself as just "OMNIVIEW XE" in the memopad banner (Without the usual full "David Young OMNIVIEW XE ©1985". The memopad mode outputs garbage if you try to type in 40 column mode, and will reset when pressing some edit keys like Shift-Clr. If pressing Ctrl-Reset to kick it over to 80 column mode, the memopad mode works fine. So, I think the 80: E: handler is still active in 40 column mode, so its writing bitmap garbage to the screen memory, and display list.

 

Mathy's site lists 2 CRC's that match the first 2 above, but the 3rd I don't know much about. It just seems to be a buggy version, who knows where AtariMax got it from...

 

These keyboard shortcuts work across the three though. (I only ever knew about X=USR(49152) from BASIC BITD haha)

Use SHIFT+ESCAPE, RESET for 40 Columns E: handler
Use CONTROL+ESCAPE, RESET for 80 Columns E: handler

I'd go with Omniview 6 (256K)

Thanks for the advice.  I will give the two Omniview versions a good roadtest in the next few days.  I already have the U1MB Omniview flasher ATR built; I just need to find a few hours that I can set aside for some uninterrupted work.

MyBIOS will do fine too.

Most patches are done, supporting XL/XE and 400/800.

 

I, myself, have #5 running.

That has some extra adjustments, to comply with some other weird atari-"standards".

>MyBIOS-ROM.ROM or the -FMP that has the mathpack) substituted by the fastmathpack ,

Hi Sijmen-

 

Good to hear from you! 

Does MyBios work as a general purpose OS (without the MyIDE)? If so, I'll give it a try with my project.

Hey Larry,

 

Good to see you are still going strong.

Best wishes for the new year.

May it be full of Atari-goodies.

 

Yes, the latest series MyBIOS without the version-numbers are stand-alone BIOS for the atari.

The MyIDE portion is a plug-in, loaded from the MyIDE-][ cartridge.

 

If you want, I can pm you version #5, with or without FMP.

See below for the change log.

That will be a w.i.p. version, but I have added some patches since my last release, already 02-02-18.....

 

Currently occupied with LiteDOS, coding for the A8 makes me happy.

 

Grtz,

Sijmen.

 

Change-log:

2019 V05
MyBIOS:
-Write to stimer when set to 1hz (reset timer), removes unwanted timer-IRQ's
-#DiskTimeOut -> 7s (atari-standard)
-115k2 does not work on pal... (115k2 completely removed)
-Conditional nmi/vbi-patch on io, modified.
-Config-BYTE, rely on portb-bit2 not BASICFL (ACEYDEUC)
-SIOV-exit, compatibility. (A=0)
