Has anyone tried this in the Presario 7x / 9x machines..... I just got 720 and thinking of buying /building 1 of these....

https://theretroweb.com/motherboards/s/compaq … -900-series-486 is directly linked in https://github.com/wichers/Compaq-Cache-Module-197005-001 so yes

Only issue is I only need 1 not 5 or 10 when you do a PCB way order.....

does it matter how many you order if total is still like $5?

I think I'll give this a shot but in your github it's missing a BOM for the components? (unless I'm completely blind - also a possibility)

good catch, neither does mine https://github.com/raszpl/FIC-486-GAC-2-Cache-Module 😐
you have to download Kicad, load the project, select diagram, and then view BOM

I'm a complete idiot when it comes to electronics - but I can solder. I just upload the gerbers.zip file to PCBWay and order the boards that way, right?

afaik jlcpcb comes out cheaper, might depend on shipping, but in general yes
