how do i format bubble memory

[MT4X4]

I have a S-100 with a R-F controller "I think". When I got it, it had some bubble errors so I tried to format it. I have 2 bubble cards both came up with different errors, 0007 0018 and 0007 0008 and at one time I saw a 0007 0010. Anyways I found this.

It was a little different. I dent need to do step 3.

3) Press "4" for "Bubble", then "2" for "Write by manual". You will get a message "Make BMU switch on".


I did need to flip the switch. So on step 5 I have 21 different 3 digit numbers and I don’t have a start. So after only getting half of it done because I don’t know what numbers to put in and I don’t have a start I get an error 0004 0200

My sticker on my bubble memory looks like this


A005 007 025 162 229 231 242 258
264

*** 423 *** 9
B046 138 215 217

*** 616 *** 4
