Re: C103414 - STFM 4 x SMT DRAM

Re: 2600 Composite mod

Cool!

I have a bit of time off now, hopefully I can get back to looking at this. Just got to solder in another RAM upgrade and blitter to an STFM and I'm good to go :)

RAM chip source

Hi all. This is just a quick post regarding a source of 41256AP-12 ram chips. I recently bought 50 of these: https://www.utsource.net/sch/KM41256AP-12 Last night I upgraded one of my STFM mainboards, a C070789-001 REV .F to 1MB on board RAM using these, and it all went great, so I thought I'd let ev...

Not sure I follow... Whole idea of this booster is to avoid the PLCC socket for the CPU..

Re: STE V1.5 32MHz BOOSTER - STATUS

Ouch, that CPU looks like a bit of an arse to solder. I guess since the pin dimensions fall inside a PLCC socket, that means a socket for the CPU is a no go?
