for a 16 bit 6502... would not it be wiser to simply take the 65c816 and just give it more pins (no more time multiplexed busses, just put it in a dip 80 package ;) there. true 16 bit. retaining full compatibility with everything. still 8 bit opcodes and parameters capable. (kinda like the 8088 also ...

and now we get to the actual 'producing a chip' part... wth is 'super-q the wafer' ? :P or a 'morning machine' and where to buy one :P and where does one even obtain 'virgin wafers' or all those chemicals in larger quantities :P hmm. think it's simply time to make a good offer on texas instruments ...

i'd say just xor'ing it with another counter -running at a different frequency- -preferably in the other direction- (although that is easily solved by in turn substracting that or inverting that, but that requires more cpu registers)... such as oh eh. the current lowest 8 bits of the raster counter ...

not exactly 'hobbyist' considering that i'm considering to buy a cmos chip production line just to get the stuff we actually NEED no ? :P can't exactly explain to a customer that their missile went missing somewhere. lol. "where did it go? oh probably into that house over by the big smoke cloud ...

as for sockets doing what i'm describing: try going through some old equipment that's been around the block :P you'll find plenty and they don't even need to be anywhere near a leaking battery. some moist suffices to screw up joints between package pins and sockets... then try to get the plcc chip ...

PLCC sockets... what is it they do again? ah yes. they grow green edges where the contacts were supposed to be and need reseating.(and when you try that usually the entire side breaks off cuz the plastic has dried out) (probably not in the first 5 years but definately after 20 or so ;) still better ...

thing is manufacturers should just make what we want them to make. which is the proper stuff. not the cheap stuff. the market currently works the wrong way around with 'nxp' deciding for us which package types we should use. (don't give a rats ass about the price either... it should simply be made ...

essentially you're pusing matte-tin (rohs) against copper plated springs. that is gonna corrode at some point. if you simply solder it with pbsn you flush their primer off and replace it with lead. which won't whisker or corrode. but repriming them with pbsn won't work if you wanna put them in a ...

considering that the 65C51 literally is cheaper than a lightswitch maybe it would be better if they simply asked 50 bucks for the things but made sure they work instead. :P lol. hmm. those PLCC sockets usually grow bad contacts over a decade or 2 plus the plastics get brittle. PLCC in a socket is ...

coming to think of it in this -specific- case the broken 65c51's might as well work as we need to read the bytes we wrote to the canbus driver back anyway to see if there was no collision (it's half duplex and both the tx and rx driver are connected to the bus independently so if anything else ...

it seems to do some more things like detecting framing flag and addressing too (kinda odd for a serial port to do that internally). but the packaging sucks. sure we can solder pins to the bottom of an smd device (Rather weld them to prevent them coming off again in the solder bath ;) and put some ...

yuk. the 28L92 (like pretty much all things NXP) is smd-only. but then again we could buy a machine to bend the pins down and weld a piece to it but that'd make it even more inferior no lolol.

are these current production chips? last batch i ordered was 2017'ish which by now is 3 years ago so i would expect them to have fixed it by now. (been using harris cpc65c51AE2's from china overstock (heck they're cheaper too ;) so far but it looks like we need to change that soon as intending to do ...

the microsemi MT8952B seems to be originally intended as an ISDN x.25 controller for the d-channel and to be interfaced with motorola 6809 controllers (also usually in isdn terminal adapters ;)

it does however seem to do all the things the MC6854 Advanced Data Link Controlle (no longer in mass ...

considering your use of the word 'modern'. what's so 'modern' about deliberately selling crap that breaks all by itself within a year or 2 after leaving the shop and refusing to sell new units of the same type. i thought scams pretty much where the oldest commercial concept besides the prostitution ...
