could you use this as part of multiprocessing in bit slice form, ie:
6502 Lo has overflow, send Address or other Pin, to SO on 6502 Hi, and 6502 Hi can test this on certain operation chains.

I have Discord on my phone and Desktop. Ive been chatting online since the dial-up BBS (bulletin board service) days and everything BDD mentioned, has been around since the beginning. I used IRC for a long time, my handle was Storyteller on freenode IRC network. I got introduced to people that ...

for sure, it is not for everyone, I moved over when IRC started to get tedious
the two factor authentication can be a real pain these days.
you are especially welcome Garth.

I made a discord server if people want to chat or use the voice call features there.
We might host an event one day for a "Code Jam" using their evet system, though
mostly it is intended to be a chill place for 65xx Development. Forums and Chatrooms
are very different. If anyone wants to join ...

here, this is more what I am trying to do, from a step back

here this might be a little clearer, kicad sometimes puts chip ids in when I just want generics.
I swapped the DFF, really, it should just be Toggle or maybe a latch.

I think the middle is a bit cluttered and could probably clean it up a bit. the DFF/Toggle should be 'earlier ...

ok, this is what I came up with, and I think Im overdoing it with the schmitt-triggers, and could move that Flip-Flop/Toggle there (that should switch its state from hi-to-low or low-to-hi on each button press.)
555_FastClock _A.png
Im thinking it could be put behind the first trigger and omit the ...

is there an assembler for 6502, (and/or text editor) that is native to/runs on the 6502 itself?
Is there call for one?

... synthesis to a cpld or fpga is possible,... writing schematics or soomething, the 'netlist', turned into a svg file is good, or a png our simulator, might be more like circuitverse or logisim ...
Synthesis to the +5v 150[2/4/8] CPLD's would be a fine reach, but a good first aim would be ...

wayfarer,
after reading your text I'm getting the impression that your intention is not to build a 6502 from Bitslice components,
but to use multiple 6502 chips like Bitslice components for building a bigger CPU.

This might be a nice starting point.
you have that ----- kinda----, Im ...

Could you bitslice the 6502 so its 16d/16a, or 16d/32a ?
In theory, most anything thing is possible. The more immediate question, I would think, is what do you hope to accomplish?
.., .... The primary driver of bit-slice technology was the desire for higher clock speeds and wider buses (both ...

I think this is a fantastic idea. Good luck with it!
Be sure to update us all here with your progress!!! Some posters have a habit of talking about ideas but never following through with implementation. I know I've done that myself, but work and real life tends to use up the time I'd rather spend ...

I don't really understand the question. ... snip ...
Or are you talking about using an actual 6502 chip as the slice? That's ringing a bell - I feel someone's asked that before. I won't say it's impossible, but it certainly wouldn't be easy and the results are likely to be ugly. Bit-slices aren't ...

Could you bitslice the 6502 so its 16d/16a, or 16d/32a ?
i searched and its not really covered. Will it work?
Id think a custom interface instruction decoder on a cpld might be needed, or a lot of glue logic.

so I have a 6502, and i have no ROM!
no way to flash one, and no way to use an mcu and a ROMulator!!
