07:02 AM polprog: is it ok to mix two eproms with different access times for high and low eproms?
08:11 AM rue_mohr: as long as the slow one is fast enough
10:50 AM aandrew: yeah I was just going to say as long as your access time is slow enough for the slowest device

10:51 AM aandrew: I have a bunch on hand all the time, handy for spitting up the IP address and basic debug info when developing

08:07 PM aandrew: rue_mohr: the driver is really simple, but I stole some pretty nifty font/primitive drawing code that is completely display agnostic
08:07 PM rue_mohr: ok
08:07 PM rue_mohr: I was pondering a dot font like the led displays
08:13 PM aandrew: well you can do whatever you want of course :-)

10:16 PM aandrew: you can suck up metal filings/shavings/etc with a regular old shop vac can't you?
