Here is a working, hard to find 80 column display card from Newell Industries called the Ramrod.

Paper manual and installation instructions included.
This card replaces the OS card with a OS B, The fast math ROM, and your choice of Omniview, omnimon, or 4KB SRAM in the address space of c000-cffff.


Incliudes the Omniview 80 column display rom add on.  Toggles on in basic or DOS by jumping to address C000  or  calling x=usr(49152).

You can also swap that rom chip for the Omnimon for assembler/testing/cracking.

Included is 2 2KB SRAMs it you want to use that 4KB space for programs.

The display looks best using a monitor that uses separate luma and chroma  and plug in only the luma.
