HP-150A Memory expansion #VintageHPComputers

hi all, I would like to make a RAM expansion memory card for my HP-150A which have just 256K.

To make a simple circuit, I would to use a static RAM.

PAL 16L8 (HP part # 1820-3420) source code would be really useful to me.

Someone would be able to dump it?
