Maiwand thank you for your list - I'm in the process of making a list of my DIP IC CHIPS. Have a couple on my desk tonight and your list is fairly good. Some I'm checking tonight - MMI p/n 67558-1d date code 7943 40 pin DIP white ceramic with gold pins & cap weight 6.2 g - SMC p/n CRT5027 date code 7917a 40 pin DIP white ceramic with gold pins & cap weight 6.0 g - SMC p/n CRT5027 date code 7749a 40 pin DIP purple ceramic with gold pins/cap/ground strap 5.4 g - National Semiconductor p/n MM2708Q date code 7924 EPROM 24 pin DIP grey ceramic with gold pins/window 6.9 g - AMD p/n AM9511-1DC date code 7925DP 24 pin DIP purple ceramic with gold pins/cap/ground strap4 g. Just a few but finding those weights to be fairly accurate.
