I just remove these jumpers from older electronics like floppy drives, hard disks or motherboards.
would there be a tutorial to expand the sram of moonsound v1?
Before we had this "manual" we tried it ourselves:
And now it is broken: https://www.msx.org/forum/msx-talk/hardware/moonsound-v1-issue
I think we just removed the pre-wired link and soldered in real jumpers
How should I remove the pre-wired link? Do I just cut it with a sharp knife?
If the links are mede on the backside of pcb permanently originally on the pcb, then yes cut with a sharp knife.
Otherwise unsolder or snip with pliers.
Thanks!
Today I received two HITACHI HM628512LP-7 DIP-32 524288-word x 8-bit High Speed chips I ordered from Ebay (https://www.ebay.com/itm/401706327631) to replace two RAM chips in my MoonSound.
For those who are interested, I bought two of them few weeks ago from this eBay seller at a very low price: https://www.ebay.com/itm/323999557018. I sill haven't installed them on my MoonSound v2, though (I hope they will work OK, they look good and were well packaged).
