OSNXL, Omnimon and Omniview are all just replacement OSs with different features. The Ramrod XL is a circuit board which plugs into the 800XL OS socket and has sockets for 3 OS chips, with a switch to select the active OS.
The review you read must have been for the Ramrod XL, like this one. The review could also have been for an OSNXL already installed in a Ramrod XL which didn't state which features were of the OS and which were of the circuit board.
OSNXL is the Omnimon plus custom (fast?) 800XL OS, it is one OS chip. Ramrod XL is a three OS simple plug-in (if socketed OS), that holds OSNXL(has Omnimon monitor), Omniview(80 col), and stock XL/XE OS.
Omnimon is a fantastic device, you hit OPTION/RESET to enter the monitor and from there can do lots of things, most notable dump any cart to disk sectors. Then use my RW13 to dump sectors to a file.
You select the OS you want with a three-way switch. You can use any three OS you like, you don't have to have three, I don't have Omniview, only have two OS, stock and OSNXL.
(I think you can dump memory to a file with DOS 2.5/MyDOS 4.53 write mem to file, but I never realized that). B&C sells just the OSNXL OS for $30. Newell sold the RamrodXL three OS plug-in device.
I don't think B&C sells the RamRod.. Today, probably if you want OSNXL and every other OS known in the universe, you might consider a Atarimax 32 in 1 OS upgrade, I don't know if that requires
soldering, probably does.
edit: OSNXL was also a Newell item) AND just to be complete, a RAMBO XL is a 256K Newell XL/XE upgrade.
AND ALSO ICD bought Newell and FTe bought ICD.
