found a funny site about modding a SO DIMM for the 2400.. use google translate.. https://macmem.com/wp/2019/08/05/9236/ :ROFLMAO:

thats a lot of valuable info ..reading through the two PDF I wonder how you would compare the form factor of a 3400c RAM expansion module ( has only one side populated) with that of a SO-DIMM 😳..and the connectors maybe a new interesting community challenge..as there is obviously a demand...

..we need one of those RAM sticks to do an examination:ninja:

ok, little update on the RAM, I bought an IBM branded, 64MB, EDO SO-DIMM 144-pin 60ns 3.3v stick, after boot in 8.1 only half of it, 32MB are being recognized..ok, better that before, but still strange. ( I cleaned the contacts three times). I asked the seller and he just went with the...

having restored a 540 and 540c I must say these are nice machines, but the 190cs is evenly good imho..ok, the design factor comes in and there the 540 are great. I wish the 190 had internal ethernet but a the 3Com Etherlink III pcmcia card still does a good job. This card works best witj older...

I also tried to replace the original quarz crystal to a 20Mhz one but it didnt work, maybe its not the correct crystal.. rechecked the soldering three times but it didnt get better, then I resoldered the original quarz back and it worked again. The 5300 also had a RAM expansion card in...

did some updates on the 190cs, I got a bombed 5300c mostly for parts for the 190..display, graphics expansion card for external, intfrared assembly, original working powerbrick and the back door. The 5300 chimed but never attempted to boot, the board has corrosion on many places, as I dont need...

its confusing, EDO Ram basically belongs to DRAM, all 144pin, not compatible with newer synchronous SDRAM, ok. EDO came in different packages, some ( as mine above) with 28 pin footprint, others with 32, but all EDO Ram run on 5V, not 3,3V. so, maybe these 32pin EDO can run in the 2400c?

ok I did a dis- and reassembly of the machine because I wanted to take a look at the actual RAM thats installed, remove the pram battery and replace the HDD with a SD/IDE card. I guess the encircled two yellow cables are those for the PCMCA/CardBus mod? ( this model is the 180Mhz model)...

So what happens if I stick one 64Mb stick in it, wont it be detected or gets it fried?

just dropped in..wow, this fella is tiny, interesting..feels very sturdy, nice build quality. 180Mhz model, english 8.6. install, came with an Buffalo Air Station 11Mbit Wifi card and the external floppy drive..the power brick is tiny! have to open it soon to look for the pram battery, I...

:poop:

do you still have the original 68LC040 daughter board? If yes, I would swap it back into the 540c and boot from it. When everything looks fine, do the upgrade and after that swap the PPC back in. And as the last step install that battery software.

I currently have 4 different irons but still not what I'm looking for..have a cheap adjustable Conrad station, Ersa Multitip (fixed temp), a cheaper adjustable and a chinese adjustable but it doesnt hold the temp very good. On YT many use the pinecil and it looks fine, but its about 100 bucks...
