@whitequark is laptop RAM really so much less expensive to grant this? 😲

@sverx the board is like $5

@JamesWidman @mer @whitequark @patterfloof Memories of 72pin SIMM boards with 4x 30 pin sockets on them... and if you had 2 slots, you needed to remember to order a left hand and a right hand one...

Three RAM adapter thingies for the corresponding DDR3, 4 and 5 sodim modules to their dim counterparts.

@whitequark I'm not against this at all. It's a nice way to recycle your existing laptop RAM.

@whitequark What's old is new again:

Back when I built my Pentium-1 I carried over several MiB of RAM on SIMM modules to those new-fangled DIMM slots using a pair of SIMM→DIMM adapters:

@glowl added, ty

@chloeraccoon @JamesWidman @mer @whitequark quick, to The Leftorium!

@datenwolf amazing, i haven't seen those before! (i am just old enough to have touched SIMMs irl)

@whitequark I see. For some reasons I had assumed the laptop RAM prices were surging too... 🤔

@patterfloof @JamesWidman @mer @whitequark Okily Dokily!

@whitequark How about the other way around? Don't tell me it won't fit in my lappy, that's defeatist! 🤪

@whitequark makes me think again of selling my laptops ram after i finish uni in the next months, now that its so expensive it could pay my rent for over a month.

@zimward surreal

@whitequark Just today I was saying that I have a lot of SO-DIMM RAM, but need proper DIMMs

@whitequark I'm kinda surprised this even works, I thought the length of traces and such matters quite a lot with DRAM

@eloy it does but only within the same byte group, between byte groups the difference could be large and compensating for it is a big part of DDR training

@whitequark @datenwolf

Once I have had removed all 640kb of RAM off a PC XT clone to check any issues, and re-seated them. Looked very much like this (image source: https://www.reddit.com/r/nostalgia/comments/h8t32l/8088_motherboard_from_ibm_xt/)

@M0KHR @datenwolf yepyep, I think the earliest physical x86 hardware I've personally operated was a sub-ATX 386 and a few 486's besides that. fun toys

@whitequark ah, right, thanks!
