I've reverse engineered the CMD RAMLink, and am happy to report I'm almost done.

CMD RAMLINK ADVENTURE
Hello All,   I bought a RAMLink (original 1990s v2 hardware) specifically to hook up to my reproduction CMD HD-4000 () via the parallel cable...

It’s baaaaaack (with a primo repro sticker I applied that looks sweeeeet!) Those badass ID# soft-swap buttons used to be holes.

The RAMlink turns the C64/128 into something magical.

One feature that might be unique (I don't have a RAMLink) is that if you plug it in to port-expander with a REU it can actually detect and use the REU as an additional partitioned drive.

RAMLink XL build complete! Had a bit of a false start, as not compatible with U64 latest firmware (1.24 was last firmware version that worked). I then tested with a C64 Reloaded mk2, but that also failed (but may work with timing clip from what I read). Switched to a real C64 and it fired right up.

I have one of Thomas's RAMLink kits on the way so I'll be able to perform the same suite of tests soonish, depending on how long shipping takes of course.

I think my retro days are over in terms of actual use of 8-bit stuff, but I loved my 128 when I had one! I had it all tricked out. RAMLink, CMD hard drive, JiffyDOS, Hayes modem, Star Micronics printer, GEOS. Good times! The scene mostly interests me now from a nostalgia standpoint.

What do they do? I was a big fan of Commodore back in the late '80s/early '90s and had some pretty cool upgrades (JiffyDOS, RAMLink, CMD hard drive) but ended up giving it all away when I moved to PC. I still love being an observer in the retro scene, though!

Hah! Back then? No - because didn't have a RAMLink, or REU, or...

So, who else have 256MB RAM in their C64?

That's RAMCard XL v3, by @corei64.bsky.social

is this the same as the ramlink?

The box also contained a 14-pin DIN cable. I already have one for my CMD HD->Ramlink, but hey.
