01:04 AM rue_mohr: I could only find _1_ 16550 in the shop
01:11 AM rue_mohr: I'm amazed
01:11 AM rue_mohr: I'd have thought I'd have half a dozen or so
01:11 AM rue_mohr: but I'm wondering
01:11 AM rue_mohr: I'm already going to put a 8253 on the system
01:11 AM rue_mohr: and I mostly wanted the 16550 for its internal divider
01:11 AM rue_mohr: it looks like the 8251 also has a line that will change state when the buffer is full
02:17 AM rue_mohr: cat just sat down on the z80 screen
02:17 AM rue_mohr: guess its a night
09:42 AM rue_mohr: so the big cnc needs a z axis
01:06 PM polprog: got a coffeemaker
01:54 PM aandrew: rue_mohr> so the big cnc needs a z axis
01:54 PM aandrew: polprog> got a coffeemaker
01:54 PM aandrew: I didn't notice two different people talking and was thinking "that's gonna make a shitty z axis"
01:55 PM polprog: haha
03:52 PM Tom_L: good there wasn't 3 of us, really screw with ya
06:48 PM rue_mohr: ha
06:54 PM rue_mohr: polprog, whats syncdraw?
06:54 PM polprog: :)
06:54 PM polprog: its a clone of thedraw, ansi art drawing program
06:54 PM rue_mohr: spend the day installing a data and power jack for a tv at a school
06:54 PM rue_mohr: ok
06:54 PM polprog: thedraw was for dos
07:26 PM rue_mohr: ok, so last night I sat down to add hardware for a led for debug
07:26 PM rue_mohr: I almost upgraded the rom to 32k
07:26 PM rue_mohr: I almost added a 16550
07:27 PM rue_mohr: but I did successfully manage to add the led
07:27 PM rue_mohr: I'm not sold on the 16550
07:27 PM rue_mohr: I need a counter and baud divider for the tape drive
07:28 PM rue_mohr: and I can get that from a 8254 with 1 spare time
07:28 PM rue_mohr: r
07:28 PM rue_mohr: and I can use that timer for a baud gen for general comms
07:28 PM rue_mohr: I wonder if I can push my z80 to 7.2Mhz
07:29 PM rue_mohr: probably not
07:51 PM Tom_L: climbing thru the wall at the school?
08:07 PM rue_mohr: attic
