6o6 v1.1 is released. This is primarily a performance update, improving guest zero page performance with a fast store path, but also cleans up addressing modes and furnishes greater control over the interrupt flag.

As a gratuitous demonstration, 1.1 includes a new example which is an Apple-1 ...

That's pretty much the situation with CHRGET in Microsoft BASIC. But it's an unusual situation, and not true of most code.

Pretty!

Nice work!

Power C was from ProLine (Jim Butterfield/Brad Templeton/Steve Punter's outfit). But I've never found C or other stack-based languages a good fit on the 6502. I think I'd only reach for it if it didn't need to be assembly-fast but faster than BASIC, and/or assembly would be inconvenient to write the ...

Nice work!

Dunno about Forth, but Aresco FOCAL on the KIM-1 does use BRK as a software interrupt rather heavily.

More games are always welcome!

It's nice work so far.

Basically an NES hello world then.

I'm a little puzzled by how the rmb/smb/etc. instructions in the table should be interpreted.

Otherwise it's very easy to read. Thank you.

That got a little tricky virtualizing the 6502 in 6o6 because guest code can execute a SED and transiently have decimal mode set before the VM records the flag and cleans the status register. On a system like the PET or C64 that doesn't compensate, this could lead to a race condition, so for the ...

A happy ending indeed.

That's a really nice setup.

In this case, Microsoft’s authority to enforce their copyright remains, despite their release of the source code and the nature of its licensing. So, in theory, if one uses the source code to create a distributable version of MS BASIC 2.0 and puts it up for sale on eBay, Microsoft can take said ...
