3D Printed SE/30 ROM Clips

I wasn't a big fan of the "rubber band" or "paperclip" brace solutions for the Mac ROM-inator II, so I decided to make some 3D printed clips for it. They press down over the top of the ROM-inator II and ROM SIMM slot, firmly bracing the ROM in an upright position. They use a simple friction fit.

There are two ways you can get it:

1. Head over to Prusa Printers and get the STL, 3MF, or GCODE and print it for yourself! Enjoy!

2. Send me a DM, and I'll send you a set for $3 plus shipping. Not really interested in making money on this, but I guess this could help me fund a couple of SCSI2SD's, eventually.

Note: My ROM SIMM is 100 percent plastic. If yours has metal clips, it probably is a different design that won't work. I don't know if there are different designs out there or not, so considering sending me a photo before "ordering" or whatever we want to call this.

Ooh, yes! DM'd – I have broken clips, and I'm not hopeful that using rubber bands are going to work in the long run.

Nice work. Now do one for the RAM slots that’ll cover the entire length ;)
Yeah, I've considered this! I do have some RAM slot clips as well. I'll post them soon (another thread).

Acknowledged! I'll get a set shipped out for you shortly.

Quick update! I spoke with Steve at Big Mess O' Wires and sent him some clips - it turns out that there are at least two variants of white, all-plastic SIMM slots.

So now, I have "Type A" and "Type B" clips available. I also made them both compatible with stock SE/30 ROM SIMMs, so you can use this with a stock ROM if you've broken a clip on your ROM SIMM slot.

Which brings me to Type C (all-black with metal clips). Does that SIMM slot ever fail? Does anyone have issues with the BMOW ROM in that type of slot? If so, I can design a clip.

I'll do some testing with these (Type B I can test here, but Type A will need to be sent off to friends to test), and once that's done, I'll post everything to both Prusa Printers for download, and Etsy for purchase. :)

The Type C slot must be exceedingly rare, as I don't think I've ever seen an unmodified SE/30 LB with such a slot installed (granted, my experience is limited to maybe a dozen or two examples, but it seems like if it is a thing that exists, the odds should be such that even with such a limited number, I should've seen at least one board with a Type C slot).

This, of course, doesn't mean they don't exist!

do have a battery-bombed SE/30 board here with slot Type C on it (see the Type C photo above). It was gifted to me by someone here at 68kmla for parts. But yeah, I don't know if it's common at all (sounds like it isn't), or if the BMOW ROM fails in it. I do have a basic design done for Type C but it doesn't quite fit yet. Needs a bit of tweaking.

Nice work! Mine are white with metal clips. I’ve never had any issues fortunately.
