970802   5560-W1B arrived 

Someday in Jul. 1997
   A guy asked new homes for some PS/55s. All free except shipping charge.  He wrote to the Forum that any one could take them but the taker might love PS/55 and/or should be ready to impart or  pass down the "MCA culture".  What a nice but serious proposal.   The 2nd condition was difficult but so far I loved  loved PS/55.  If  I could get one his PS/55s and keep it  my home then I could access Nifty when I was back in my home. Raised up my hand to be a new adopter for a 5560.

   5561-W1B was delivered to my  home.  It was a big desktop PC equipped with a DX4-75, DA B-II  and 540MB SCSI hard drive (  don't remember about memory. but probably 1 stick of 4MB 70ns SIMM was installed ).  It was really impressive to me. It was a huge server PC in a desktop style.  I named it "Big Battle". 
With Big battle I also learned a lot about IML, system partition, SIMMs usable on PS/55s and so on.

   Later on I noticed my 60-W1B was really a 60-W2B  It was labeled 556-W1B but at the same time there was a little sticker saying " KIT W2B". I don't know the difference between stock W1B and W2B but mine  had a PS/2 H'ish complex with a DX4-75 on the overdrive socket and no SX25 CPU on the first socket. 
Memory count was faster than my "Grandma" which had a PS/2 Type-K'ish complex. I added a Hitachi made 2x speed CD-ROM which I bought cheep at a used PC parts shop. As  I could not get a appropriate CD-ROM rail ( mounter?) to set it in a bay beside FDD, I bought a CD-ROM mounter for Macintosh ( forget the model number ) and adjust it to meet the slide rail of the bay. The drive and the CD-ROM still sit in my 5560.
One thing I really want is a  front bezel for CD-ROM in same shape with FDD bezel. I have a flat type square  bezel in mine but it little bit shabby.
