hyperneogeo Posted July 7 Report Share Posted July 7 So I asked Doug if I could use his design to make some modules and sell the rest to people to which he was fine with. I wanted to see if there was any interest in these. Obviously each FX would need a minimum of 4 modules, IE 64MB of ram. These boards are 4 layer, so it's not the cheapest to make and the ram is not super cheap either. It would most likely be around $25-$30 per module. Any interest?

pax Posted July 7 Report Share Posted July 7 Sure. There's also another ongoing thread over here where a few of us have already expressed interest. Quote Link to post Share on other sites
hyperneogeo Posted July 7 Author Report Share Posted July 7 Ah, someone is already doing a run. Well, I'll let him sell his first. Quote Link to post Share on other sites
olePigeon Posted July 7 Report Share Posted July 7 I'm interested! I'm waiting for anyone to make a set, really. I'd like to get 128MBs into my IIfx. Quote Link to post Share on other sites

Unknown_K Posted July 7 Report Share Posted July 7 So $25-30 a module assembled and tested or kit form? Quote Link to post Share on other sites
hyperneogeo Posted July 7 Author Report Share Posted July 7 Assembled or kit form really. Quote Link to post Share on other sites
tappdarden Posted July 7 Report Share Posted July 7 count me interested! Quote Link to post Share on other sites
maceffects Posted July 7 Report Share Posted July 7 I'm thinking I might be interested in 8 of them. I don't have the IIfx but it might be nice for one day... Quote Link to post Share on other sites
hyperneogeo Posted July 7 Author Report Share Posted July 7 Ok so I just tested the ones I got and they work fine. I'm ordering 100 boards which should be here next week. Quote Link to post Share on other sites
MrFahrenheit Posted July 7 Report Share Posted July 7 I'm interested. I have 2x IIfx machines. Quote Link to post Share on other sites
hyperneogeo Posted July 7 Author Report Share Posted July 7 (edited) So basically I'll be making 25 sets of 4. Seems better to sell them in sets of 4 rather than 8 since some people probably won't want 128MB heh. This is probably the only run I'll do since it's so time intensive...especially since it's gonna be 100 modules. If people want to assemble it themselves, I can provide the kit...it might save something like $5? I dunno at this point heh. Edited July 7 by hyperneogeo Quote Link to post Share on other sites
ArmorAlley Posted July 7 Report Share Posted July 7 On the one hand, these are almost certainly an investment. A IIfx with 128MB will command a much higher price than one with merely 32MB, and surely the price-difference will be greater than the $240 required for the new RAM. Sets of 4 are a good idea. 64MB RAM in a IIfx is almost obscene, but the extra 48MB will make a useful RAM disk. It also allows more apps to run on Mac OS 8.1. I do want to buy some though.

Byrd Posted July 7 Report Share Posted July 7 + interested please; full 128MB set. JB Quote Link to post Share on other sites
jeremywork Posted July 7 Report Share Posted July 7 Please put me down for eight sticks if you haven't sold out. 128 may be overkill but extra application memory combined with a big RAM disk really increases the machine's utility. Quote Link to post Share on other sites
hyperneogeo Posted July 7 Author Report Share Posted July 7 (edited) I'll start making a list when I get them, but I'll give priority to the people who expressed interest here first. I'm shooting for $25 a module with a min of 4. Edited July 7 by hyperneogeo Quote Link to post Share on other sites
Bolle Posted July 8 Report Share Posted July 8 (edited) I made a two layer version out of the schematics that fly around on the interwebs because cheap: Couldn't get them to work reliably yet because of the whole PCB thickness thing. If you wiggle them around before use and put on rubber bands they are ok for a while. What thickness did you choose for yours? I ordered some in 1.6mm as well as 1.2mm from JLCPCB. 1.6mm is really tough to get into the socket and 1.2mm is more on the floppy side of things.

hyperneogeo Posted July 8 Author Report Share Posted July 8 (edited) Well my first ones were 1.6mm, but they are WAYYY too hard to get in/out of the socket. I basically had to wriggle it back and forth multiple times for it to fit in the socket and getting it out felt like I was going to rip the whole board with it. I measured the original ram I have here and it's around 1.2mm, but if it needs to be a little bigger, then I'll do some tricks I guess heh.

hyperneogeo Posted July 8 Author Report Share Posted July 8 Also bumping the inner/outer copper on the board might help get a better fit. Quote Link to post Share on other sites

I measured the original ram I have here and it's around 1.2mm, but if it needs to be a little bigger, then I'll do some tricks I guess heh. The boards need to be 1.27mm thick. The original spec. is for .050", which is 1.27mm. There's some +/- in that spec, but really not enough to go to 1.2 or up to 1.6. 1.6mm is .063" thick board, which is far thicker than .050". I'm amazed that you could get it into the socket at all. I posted some datasheets for SIMM sockets in an old thread, which included the specs for boards that fit into the sockets.

hyperneogeo Posted July 8 Author Report Share Posted July 8 Well with the 1.6mm it is possible to get them in there, I just wouldn't recommend it. You have to kind of put it on top of the socket then rock the simm back and forth until it goes in. It might be a good option if you never want to take it out again, but taking them out is really scary lol Quote Link to post Share on other sites
AppleTree Posted July 9 Report Share Posted July 9 Hi would you ship to the UK? I am interested too Quote Link to post Share on other sites

AppleTree Posted July 10 Report Share Posted July 10 20 hours ago, hyperneogeo said: I will ship anywhere in the world Great. Count me in for 1 set (4 modules). I was thinking of getting 128MB but I think that's probably a little over the top (though it would be cool to look at "About this Macintosh" and give myself a satisfying nod ) Quote Link to post Share on other sites
