Introduction
I have had this computer for years but just never got around to working on it until now. There was a general question about the possibility of connecting a SSD to this computer. For now, this one will have to get taken apart, cleaned, and possibly recapped. After that we a re going to see if the SCSCI hard drive can be replaced by an SSD.

Here is one of the vintage computers in my possession. It is a Macintosh Classic II M4150. Apple considers this obsolete and " information about these products is no longer updated as of 9/1/98 "
-
On powering it up, It originally greeted me with a checkerboard pattern that quickly converted into this pattern. The checkerboard pattern is/was commonly caused by bad Ram memory. Considering the age of this computer, leaking capacitors are a strong possibility. Time to check.

The cover is held in place by four (4) T-15 screws. Two (2) on the bottom

and two (2) under the top (handle)
-
The bottom ones are easy to remove
-
The top ones are a bit of a challenge due to the depth of the holes.

-
There was just not enough room to get a good grip on the driver.
-
Luckily this iFixit driver has a hole on the top part. I used a tool to gain some mechanical advantage. While applying downward pressure on the driver, turn the tool to the left to loosen the screw
-
Once loosened, the iFixit extension that came with my set, works perfectly to remove the screw,

Here are the four (4) screws. The two bottom screws are M4X15mm The top screws are those typical found in plastic to sheet metal joints.
-
With the screws removed the cover will slide off.
-
BEst practice is to lay it down and pull the case straight up. It may take some force due to the tight fit and years of storage etc.
