redman Posted July 16, 2007 Share Posted July 16, 2007 Hello all, Does anyone have the 16K rom image for the OSNXL upgrade? I can't find it anywhere on the net. I want to switch between 4 different OS's on an Atari 800XL and I would like to use (1) the original rom, (2) fix xl, (3) Omnimon, and (4) OSNXL. I'm going to burn them all into a 27C512 eprom and use a switch from an old SCSI hard drive to select the OS's. TIA. Ralph Quote Link to comment Share on other sites More sharing options...

Ralph I have an 800XL with the RamRodXL board in it with OSNXL rom as one of the OS'. I can dump it this evening, if you want, as long as there are no objections from anyone.

I wasn't sure if they were separate OS's or not. If they are, then I already have what I need. Quote Link to comment Share on other sites More sharing options...

My memory is very sketchy. Wasn't OSN XL the Fast chip (or something like that)? - Steve Edited July 16, 2007 by a8isa1 Quote Link to comment Share on other sites More sharing options...

+Guitarman Posted July 16, 2007 Share Posted July 16, 2007 (edited) RamRodXL was aboard that allowed you to have and switch between 3 OS's. It came with one, which was OSNXL. OSNXL was 3 things in one, a new OS (OSNXL), enhanced math (FastChip XL) and the hardware monitor (OmniMonXL). This was in one eprom. The second socket could be used for the stock OS (which had to be removed to install the board). Below is a link to the ANALOG magazine writeup on RamRodXL. RAMROD XL EDIT... Beat me to it!!!

I really would like to see the dump of your eprom. I have 2 OmnimonXL images that differ by 2 bytes. If yours matches one of them, then that's the one I should use.

I still haven't gotten around to installing the 16-in-1 you burned for me. Living with the 4-in-1. - Steve Quote Link to comment Share on other sites More sharing options...
