05:11 AM rue_mohr: polprog, god, this project is getting lots of attention
05:21 AM rue_mohr: I might have just given up by now if it weren't
05:38 AM rue_mohr: 55 likes? ooz there are a lot of retro people out there..
03:35 PM rue_mohr: eee gad, I got 6502 people comming out of the woodwork everywhere about this one!
04:22 PM aandrew: hahaha
04:31 PM aandrew: the shift right into carry, shift left out of carry is probably the smallest way to do it, but I wonder if a 16 byte lookup and then loading the correct nybbles using & 0x0f and & 0xf0 has any advantage
04:31 PM aandrew: probably not though
04:33 PM rue_mohr: :)
04:33 PM rue_mohr: I'd probably go with a shift, that little clip that was posted looks great
04:35 PM rue_mohr: for my Z80, I'm building a function rom
04:35 PM rue_mohr: its an 8 bit x 8 bit paged rom
04:35 PM rue_mohr: so takes up 256 memory, but you write the fn you want performed to the page
04:35 PM rue_mohr: and then use your data as the index
04:36 PM rue_mohr: things like Sin, Cos, binary to ascii, ascii to hex
04:36 PM rue_mohr: isdig/isalpha
04:36 PM rue_mohr: a bit reverser, a bit counter,
04:37 PM rue_mohr: square roots
04:37 PM rue_mohr: ok I cant really try to keep up with the twitter notifications now
06:04 PM aandrew: you're an influencer now
06:49 PM rue_mohr: haha no
06:49 PM rue_mohr: I keep finding analysis sites that say I have 0% everything
06:50 PM rue_mohr: I'm sure their rounding
07:42 PM Tom_L: you finish the shed?
09:36 PM rue_mohr: long ago
09:36 PM rue_mohr: didn't sell tho
09:43 PM Tom_L: :/
09:49 PM rue_mohr: 2804!
09:50 PM rue_mohr: once I'm done the 6502 based stuff it'll drop like a rock :)
11:35 PM rue_mohr: https://spectrum.ieee.org/q-a-with-co-creator-of-the-6502-processor
11:45 PM rue_shop3: wish I could talk with him about the 6522
11:46 PM rue_shop3: I see intentions there that didn't get expressed properly in the final design
