I could think about gitHub or SF. But it will have to wait. I'm pretty much out of circulation for 4-5 weeks.

But I am going on holiday!

No worries Dave. Just doing my part to keep these gems alive.

I've been trying to get CEGMON assembling, working and annotated, in that order. I felt there was no point in annotating code that I could not assemble or that did not work. I started with the cegmon-c1.asm posted in the zip file in the Software section of this site : http://www.osiweb.org/roms/cegm...

New update in post 1 at top of thread.

@dave. Yes, the 6502 emulator is a real gem!

If you've not tried Michal Kowalski's 6502 emulator, I highly recommend that you give it a gander. It not only has an assembler, but it allows you to run the code, inspect memory and registers, set breakpoints and debug parameters, dissemble, save memory in multiple formats, load memory from multipl...

Anyone using that source (as posted by Dave) for CEGMON should be aware that the usage of some instructions does not work with many assemblers. That source uses a strict form for such instructions as Rotate Left, Accumulator Shift Left and Local Shift Right when the operations are performed on the a...

I wish it could do C4P video. Oh well. And speaking of video, it would be nice if our machines could be connected to a modern VGA monitor since monochrome and crt-based monitors are either scare, or expensive and bulky. There are many small, cheap LCD TVs still out there that have composite video i...

As a side thought... Would it be possible to have an option to map the ram starting at $0000? Then people with defective 2114's could remove them completely. It would also reduce the power requirements of the board! Steve Not a bad idea. That might be doable without adding any real complexity. It's...

Welcome Steve!

Has anyone ever looked into patching OS-65D or HEXDOS to use the WD1772? This would open up a lot in terms of useability in the OSI world. like this: http://www.ebay.co.uk/itm/SD-C-HXC-Floppy-Emulator-Rev-C-/181673414323?pt=LH_DefaultDomain_3&hash=item2a4c944eb3 Or even common or garden variety flop...
