  1. Dan, did you print the original case or the one with the opening? Mine fits perfectly when using the case with the opening. If it still doesn't work, don's email me! I'm just the guy who saw a need and opened it up to the community! @weird_w I'm thinking there will be people who could use different cases. Heck, there are probably people who could use a full 4A case! So, if you like tinkering with stuff like this, knock yourself out! Here's a thought, how about that gear in the printer/plotter that keeps stripping out! I know several people who'd be all over that one.
  2. I've been working with amiman99 for the past few weeks and he has come up with a replacement 3D printed case for CC-40 cartridges. He has graciously released this to the public for others who need these. One note, these will not quite fit the new EEPROM cartridges from Retro Innovations as it covers the DIP switch and using a socket for the EEPROM makes it a bit taller than allowed for in the case. He is working on a modification for allow for those 2 exceptions and, if he is willing, he may release the altered design here. However, if you're just needing a replacement case for a regular cartridge AND you have a 3D printer, here are the necessary files. Enjoy, Curtis cc40carts.zip
  3. Third time's the charm. Or 3 strikes... I'm rooting for the first!
  4. Message sent requesting address. He's closer!
  5. With the development of cartridges for the CC-40, is there anyone with a 3D printer that could make available for a reasonable amount of money cases for the cartridges? This could also come in handy for someone who has a busted cartridge case and wanted a replacement! Shouldn't be too difficult if you know what you're doing with the printer, which I do not have nor have any experience with. Just a thought.
  6. Why clear the bench? That's the way to lose stuff. Just shove it into a corner. Ask me how I know!!!
  7. There's an 18K CC-40 on ebay. https://www.ebay.com/itm/264459330543 He's a bit high on price, IMHO, bit still factory 18K.
  8. I, for one, would be interested.
  9. So, I've been playing with the ROM board from Retro Innovations and am quite impressed with it. However, I'm curious. There are several components not needed for the ROM version and am wondering if this same board could be used for a RAM upgrade. It looks like it could given there is a place for a 3v battery. If this can be used for a RAM upgrade, what components would be used and what is the max RAM that can be installed? Would all the RAM be available or would it be paged? Curtis
  10. Keep plugging on that SD card. Given the schematic for the PCIF is out there does that make it public domain now or is the big, nasty TI still clutching onto the rights for it? You'd thing after so long they'd release it.
  11. Still cleaning out that closet! Olivetti M10 (Brit version), TI Hexbus RS-232, and some older Casio and TI calculators. My ebay user name is mcmccain.
  12. Maybe we can persuade Jim to offer a PC Interface module. Couple that with the hex to dockbus adapter and the CC-40 will have a storage possibility along with a PC display function! Do we need to have a survey to see what sort of things people would want for the 40 and it's cousin the TI-74? First on my list would be a PCIF followed by a floppy drive and then get the SD card reader up and running for either the hexbus or dockbus. Who's next with their wish list?
  13. And then Zenith bought them out and Heathkit disappeared shortly thereafter.
  14. At my first duty station, our main communications computer was called Streamliner. It's nickname was Screamliner for the sounds it made when something was wrong. It had a wire wrap panel that was about 2 feet by 3 or 4 feet. It had a habit of shedding at least 1 wire every shift. Really annoying part? All the wiring was blue. We all felt sorry for the techs that had to work on it. And they wouldn't let us "normal"/non-school trained techs get even close to it. Not that we wanted to!
