Hi, I would like to build my own amateur training computer with 4040 chipset. But I need some description (datasheet) for memory controller 4289. Only first page of this datasheet is available on popular datasheet servers. Please, have somebody scanned complete datasheet 4289?
I have built simple test computer with 4040, 4201, 4002 and 4289 + Eprom yet. But I have some troubles with program RAM and 4289 interconection.
