Help ID'ing some chips

[KLund1]

Hello,
  I found a small box of chips with an A3000. There were a couple KickStarts ROM's and these below.
I am looking for a little help identifying them. I could not find much in google. SO I thought I might try here.
The large chips on the left are ST Z8530B1 SCC 29131
The right are :
08-903-u24 with a wire connected to pin 3
12-902-u17
07-904-u21
02-902-u26
10-902-u27
Not pictured a square PLCC
MOS 8370 2787 23

Any help will be much appreciated
Thanks

The 8370 is an OCS Agnus, NTSC

The 902,903 and 904 chips are for the VXL*30, but I'm not sure whether they're upgrade chips or leftovers from an upgrade.

That is most helpful.
Many thanks!
