The via and rom are working #mos6502 #bobross

I’ve realised that I don’t have a good #offline #Z80 / #mos6502 reference. Does anybody have any recommendations for ebooks — must be epub, NOT PDF, or a simple ‘personal wiki’ tool for writing offline-first documentation?

The WDC 65C02 and its variants get used in lots of embedded applications. The last major revision was the never released WDC 65C832 (1990) the most recent revision to actually hit the market was the 65C816 (1985). Some of the Rockwell variants may be newer, but not by much.

Is the #MOS6502 a evolutionary dead-end? Or, could we realistically see future enhanced revisions?

@johngbell95 @haitchfive @thomasfuchs I ever got to use a BBC Micro as it was from the other side of the pond, but I'd love to some day. The most esoteric 6502 I ever owned was an Ohio Scientific Challenger 4P. Talk about lack of documentation! LOL!

@haitchfive @thomasfuchs Commodore released an excellent Programmer's Reference Guide for each of their computers (VIC-20, C64, C128, etc) and there was a wealth of information from third parties. Most of what I learned was from Jim Butterfield and his excellent books!

@haitchfive @thomasfuchs I am fortunate that my assembler experiences on the 6502 were much better. I started out by just POKEing my stuff into memory. Later I typed in and used a simple assembler called TinyMON, and finally I wound up using VICMON.

As for hashtags, maybe #MOS6502 ?

@dfx Code some #MOS6502 code? 😏

@jhx I would like to draw the valued attention of the audience to #DuffsDevice. I think it proves that #C indeed is a portable #assembler 😎

But seriously, many C constructs map very nicely to machine instructions of many platforms, so there is some truth to it.

I only ever touch assembler for the #MOS6502 because its instruction set and general design (e.g. the fixed system-wide and pretty small stack) indeed isn't a great match for C...

Am I alone in being interested in understanding / reverse engineering #retrocompiting software OTHER THAN games?

If I'm not alone, what stuff would you want to see migrated to maintainable #mos6502 #assembly code, probably #ca65 , and MAYBE ported to the #commanderx16 or the #mega65.

@vingtroiseize I still prefer the veteran, it speaks a simple and clear (machine) language 😏 #C64 #MOS6502

Every time I switch from writing #mos6502 to #Z80 I get tripped up by `LD` not setting flags (why not??) and `XOR` clearing carry!

Well, a nop test through the backplane seems to be working. I’m going to build some simple cards before tackling the crazy screensaver logic card again. #mos6502 #homebrew

@kithrup @Houl so a #64bit version of the #MOS6502?

I mean that could be feasible given a #PLCC-288 or some PGA-ZIF-socket...

https://en.wikipedia.org/wiki/Socket_4

@Houl Also the #MOS6502 and it's successors like #65C02 & #65C816 have several key advantages:

- swappable & upgradeable RAM
- swappable & upgradeable Storage
- Expansion buses!

All is very well in the #MOS6502 solar system. #NoMansSky

It has come to my attention that, in some cases, Australians were forced to use a computer named “The Dick Smith Wizzard.” I did not misspell the last word.

I think the entire computer industry owes you an apology.

My thoughts are with you.

Questions:

- Who is Dick Smith?
- Was he only stopped when he was executed by an elite paramilitary team?
