Thanks for the heads up on the EPROM used.

The TRS-80 Model 100 uses another variant of these goofy Molex sockets and some clever folks designed a 3D printed carrier and PCB layout with castellated PCB edges as contacts. This would be a good jumping off point to design a PCB and carrier. You can also get the 68674 for ~$1 on eBay as well.

I have a saved search on eBay so hopefully some of the capsules will show up.
