Building a flash + RAM board for the HP9000 computer

In this video, I build a memory board for the HP 9000 computer. I try this is my 9920, 9836, and 9000/310 computers. This board has basic 5.1 in flash (alternative, could use basic 4.0 or HPL) and it has 3 megabytes of RAM. I also demonstrate using these boards together with DMA and a high-speed disk adapter. It took about 4 tries for me to finally get this board right and completely working. For more vintage computing and electronics videos, see htttp://www.smbaker.com/
