Which other Macs have suitable GLU chips for the SE/30?
Posted by: smrieck511 on 2026-04-13 18:21:59 Need to find another one the cheapest way possible. Thanks for any help.
Posted by: finkmac on 2026-04-13 19:44:46 iisi i think. are you SURE your glu is busted?
Posted by: Callan on 2026-04-13 22:25:11 You can get them off iici and iicx boards too. I believe the Mac ii series glu s the same, but not 100% on it.
Posted by: robin-fo on 2026-04-13 22:31:50 The GLUE is only in the II, IIx, IIcx, SE/30 and a certain variant of the LaserWriter II. Sure yours is damaged? This is the most valuable part on the logic board! (Or why are you asking?) The GLU is a very different chip and not compatible.

This is the most valuable part on the logic board! (Or why are you asking?) The GLU is a very different chip and not compatible. Apple sometimes refers to the GLUE as GLUCHIP. Here’s a photo of a IIcx logic board: Which is the other GLU you are thinking of?
Posted by: smrieck511 on 2026-04-14 04:39:32 iisi i think. are you SURE your glu is busted? absolutely not sure but it's my best theory at the moment because it had a good deal of corrosion when it came off the bombed board. Pins were OK and it cleaned up ok. Wouldn't hurt to have another if I can pick up a iici or whatever relatively cheap.

Pins were OK and it cleaned up ok. Wouldn't hurt to have another if I can pick up a iici or whatever relatively cheap. It’s very hard to kill a Glue chip… I’ve lifted one off a heavily bombed board and after cleaning the pins it worked fine. I’ve used lots of hot air to move them around and it’s been fine. I’ve also installed one rotated 90 degrees off and it still worked after correcting my mistake. In the latter situation I was convinced I’d damaged the chip but it turned out not to be the case and to this day it lives on providing much needed vintage happiness. So I’d suspect it’s fine. I could be wrong. But it’s probably fine.

Says GLUE on the SE/30 silkscreening. What does the E stand for ?
Posted by: Phipli on 2026-04-14 08:16:34 General Logic Unit? Seems you're correct. Says GLUE on the SE/30 silkscreening. What does the E stand for ? It's normal to pronounce "GLU" as Glue, so people use the stylings interchangeably. Glue Logic is a common thing in computers, not just macs, and it is, once again, also written as Glue by some people, GLU by others. Its the GLU(e) that holds everything together. Apple does the same with DAV and DAVE (Digital Audio / Video I think?) - some documentation says DAV, some says DAVE.

Hopefully we can clear up the confusion between Glue and Glu that @robin-fo alluded to?

The 344S number should tell you if something is the same part shouldn't it? I think even compatible chips with different generations have a different 244Sxxxx number, so if it is the same, it is exactly the same 🙂

Posted by: Trash80toHP_Mini on 2026-04-15 08:43:13 GLUe and assorted ASICs are old tech with much larger/thicker inner workings than later tech. They should be vulnerable to scraping/reverse engineering attacks, no? Can Apple's custom silicon disassembled and recreated in this manner with today's tech or in the near future?

They should be vulnerable to scraping/reverse engineering attacks, no? Can Apple's custom silicon disassembled and recreated in this manner with today's tech or in the near future? To be honest, a lot of the time their functionality is fairly well documented by published apple literature, when you go back that far.
Posted by: mikes-macs on 2026-04-15 09:37:11 I was always under the assumption that the GLUe was there so that the Paste function works in the Finder and other Applications. 🙂If the Mac IIsi Glu is infact compatible for your Mac SE/30, I have a couple Mac IIsi that I don't want. They need a recap but no corrosion.
Posted by: robin-fo on 2026-04-15 09:41:26 If the Mac IIsi Glu is infact compatible for your Mac SE/30 It‘s NOT! The IIsi has the MDU instead.

Neanderthaler hacking approach appeals to me. "Well documented" and Apple Literature seem mutually exclusive in docs of that era. Building a NuBus Card was "well documented" in DCaDftMF, with several examples given, but none in complete form save for the "NuBus Test Card."
