OH-MY-GOD! 
This is just awesome! I've always wondered how they managed to put "32k" of RAM into the machine. 32k ram is just "odd" and illogical. Even the most straight looking way (using "faulty" 64k ie. 4132 chips, like Sinclair had been doing) sounded illogical for 1984, with the drop of 64k*1bit chips prices. Now, your 232 motherboard seems to have 4 pieces of 16k*4 bit chips... Absolute surprise! I wouldn't have thought that they opted for that way...  Now I can perfectly understand why they just "had to" modify the dram ttl logic of the 232...
Anyway, thank you for uploading the photo, it's a very nice board, basically no signs of age, fingerprints, etc. Probably the only ceramic packaged 6529B and 7700 FPLA t that I've ever seen. Obviously a very early 264 series machine. I'm just trying to hide my envy... (with less to no success... )
