05:44 AM polprog: if you have some assorted flash chips and want to get rid of id happily take them
05:45 AM polprog: and it looks like that 28f010 was the only one that could replace 27c010

06:19 PM Tom_L: they cannot! if you haven't heard of em!!
06:19 PM * Tom_L gives polprog some rtl logic chips

06:25 PM rue_mohr: the pinout of them is great, but apparently nobody else uses it for anyting
06:28 PM polprog: 28VF016, but you have to make a TSSOP adapter
06:28 PM polprog: they are 3v3 compatible and have the same memory org
06:28 PM rue_mohr: I think I'll just dead bug it to something else
06:32 PM polprog: That's one way
06:33 PM polprog: But there isnt much 16 bit 3.3v flashes
06:33 PM polprog: you could dead bug two 28F040 in paralell, they are 3v3 compatible
06:35 PM rue_mohr: hmmm
06:36 PM rue_mohr: 020
06:36 PM rue_mohr: 2M + 2M = 4M
