olePigeon Posted April 11, 2020 Report Share Posted April 11, 2020 (edited) I saw this thread, but user fraveydank stopped posting here years ago. Has anyone else attempted to make new IIfx RAM? Even they sold for $50 for a single 16MB SIMM, that'd still be a bargain right now. Edit: Just saw THIS thread. @joethezombie made some. If I can source the parts, can someone guide me through who/how I send the files to? Edited April 11, 2020 by olePigeon Quote Link to post Share on other sites
LaPorta Posted April 11, 2020 Report Share Posted April 11, 2020 I would also want to get in on this. I don't need to "max" mine out, but 64 MB would be nice. Quote Link to post Share on other sites
Bolle Posted April 11, 2020 Report Share Posted April 11, 2020 (edited) I made myself some 2-layer SIMMs for the IIfx based on the 4-layer design joe used. Couldn‘t get them to work yet but I also went for the cheapest non-gold plated PCB option so I suspect they do make very bad contact. Stopped to care after a few tries because 32MB is actually enough for my IIfx. Gotta dig those out and see if I can actually get them to work. In the end the hard part won’t be making the PCBs but sourcing the dual ported RAM chips you need in large enough quantities. Edited April 11, 2020 by Bolle Quote Link to post Share on other sites
olePigeon Posted April 11, 2020 Author Report Share Posted April 11, 2020 I found compatible DRAM for about $2/chip, maybe less if I can get combined shipping. Trying to see if the seller has more. I might do a bulk order and just make a bunch of SIMMs. That way I can use the higher quality PCBs. Quote Link to post Share on other sites
joethezombie Posted April 11, 2020 Report Share Posted April 11, 2020 Hi guys! After success with Doug's design, I found some NOS memory, and had a bunch of PCBs and a stencil made! Unfortunately, let's just say it's been a very challenging start of the year for me. I've had some serious events happen lately, and I've had to let some things take to the back burner. I'll see if I can find these items, and have a chip baking party. It might be a wee bit though. Sorry! Quote Link to post Share on other sites
olePigeon Posted April 11, 2020 Author Report Share Posted April 11, 2020 Oh, wow. That's quite the operation. I was looking at making some myself, but if you have a bunch already, I'd be interested in some. Quote Link to post Share on other sites
pax Posted April 12, 2020 Report Share Posted April 12, 2020 Wow. Count me in too. I'm interested in maxing out the RAM on my IIfx. Quote Link to post Share on other sites
Compgeke Posted April 12, 2020 Report Share Posted April 12, 2020 Same! My IIfx came to me with 16 megs of ram, I'm letting it down by having more ram in my Mac IIcx. Quote Link to post Share on other sites
EvieSigma Posted April 12, 2020 Report Share Posted April 12, 2020 I have 16MB currently as well and I'd love to double it to 32MB or even more. Quote Link to post Share on other sites
LaPorta Posted April 12, 2020 Report Share Posted April 12, 2020 Same, I’d be ok with 32 or 64 MB total. Quote Link to post Share on other sites
Von Posted April 12, 2020 Report Share Posted April 12, 2020 Please count me in as well. I am hoping to get one of my IIfx boards up and running soon. Quote Link to post Share on other sites
80sboy Posted April 14, 2020 Report Share Posted April 14, 2020 Count me in! And sorry to hear that this has been a rough year for you @joethezombie - Quote Link to post Share on other sites
TimHD Posted April 14, 2020 Report Share Posted April 14, 2020 Count me in too. Quote Link to post Share on other sites
Juror22 Posted April 15, 2020 Report Share Posted April 15, 2020 I'm in as well, and hope that things improve. Quote Link to post Share on other sites
CC_333 Posted April 23, 2020 Report Share Posted April 23, 2020 This is interesting. My IIfx has 32 MB, so that's probably enough. However, if/when I can afford something, 64 MB might be neat. c Quote Link to post Share on other sites

ArmorAlley Posted April 23, 2020 Report Share Posted April 23, 2020 Me too. I'm definitely interested. Quote Link to post Share on other sites
Bunsen Posted April 23, 2020 Report Share Posted April 23, 2020 Wow, I would definitely be down for a few of those. Quote Link to post Share on other sites
Iesca Posted June 22, 2020 Report Share Posted June 22, 2020 Wow! If only I had a Mac IIfx... Quote Link to post Share on other sites
MrFahrenheit Posted June 22, 2020 Report Share Posted June 22, 2020 Are you still making and selling these? I’d love to have higher capacity than some 1MB that I have. Quote Link to post Share on other sites
jjclay Posted June 22, 2020 Report Share Posted June 22, 2020 Count me in too please. Would be nice to have more than 8Mb in my IIfx... Quote Link to post Share on other sites
Unknown_K Posted June 22, 2020 Report Share Posted June 22, 2020 32MB is plenty but if you are going to make SIMMs you might as well make the maxed out ones (you don't need both banks filled anyway). Any clue how many working IIfxs are out there in the world? 1000's, 100's? Quote Link to post Share on other sites
EvieSigma Posted June 22, 2020 Report Share Posted June 22, 2020 I have 16 in mine because I couldn't find anyone selling more than 16MB at the time...I'd really like to go up to 32MB so I'd feel confident running a later version of System 7 than the current System 7.1.1 I installed.

Unknown_K Posted June 22, 2020 Report Share Posted June 22, 2020 7.1 rocks on a IIfx. What did the IIfx ship with 4x256K or 4x1MB? Quote Link to post Share on other sites

Any clue how many working IIfxs are out there in the world? 1000's, 100's? How many working IIfx are there? Very good question! Also, working when sold or working after fixing? I have two IIfx machines myself, and I’ve seen at least 5 others on eBay just in the past 6 months. So on eBay alone in the last 6 months at least 7 (including my 2). That to me indicates there are a lot more than just 100. Quote Link to post Share on other sites
