  1. That's a good thought. I'm not sure how you notice what chip you have externally. If you use hot air gun over the label it covers the screw. Does the commodore 64 have a cooling fan in the case?
  2. Good thoughts. I've used the lower powered TI cartridge games in a dual batt unit and both batts installed with no issues.
  3. Both units are wired that same as far as I noticed. I've opened 2 units of each. The extra battery gave it the current boost it needed for the cartridge games with the 8021 processor.
  4. Which battery prong came off. In the earlier models these were clipped onto the boards. The single batt units had the clips soldered onto the board. Do you still have the loose batt clip? Open it and you'll see how easy it clips back into place. A super slight squeezing of the area where it clips to the board will keep it secure.
  5. That was something I was curious of myself. You can remove the sticker with a heat gun. I'm sure a low serial number BB cartridge would have the 8021 chip installed. I'm curious on what order the game were released?? Then I was going to try it in a single batt unit and check drain. There is also the issue of today's batteries have a higher MaH rating than long ago. Maybe you wouldn't notice. Something to try though.
  6. This guy made created a couple of emulators and custom tetris and flappy bird games. https://habr.com/ru/post/416865/ If you download the github file it includes tetris files for MVEM. It has a new version of MVEM.exe needed to run the tetris game. It seems to be back compatible with the existing bin files of the already released MV games. https://www.raphkoster.com/2017/05/07/microvision-emulator-release/ Here's another take from that post on the 1 9V battery and 2 9V batteries MV units. UWP "The bulk of the cartridges worked on TMS1100, because Signetics, which released the 8021 under Intel license, could not supply MB's required chip supply. Even some games that were already written for the 8021 had to be ported to the TMS1100. This, by the way, made it possible to abandon the dangerous bundle of two batteries, because the consumption of the microcontroller from TI was only 0.1W versus 1W from Intel. I have only one of 6 cartridges with 8021, this is the Connect Four game, it was taken as a basis." So, which game cartridges had the 8021 installed. If you installed that in a MV unit with only 1 battery connections, does the battery drain much faster. I'm going to heat gun the label off that covers the screw and check. So, far I've seen the BB cartridge with both. Maybe plug in the power supply to check current differences.
  7. Like this guy did. Did you see this yet? https://habr.com/ru/post/416865/
  8. You mean like a cartridge with all of the games? If so, I haven't seen one as of yet. There is certainly plenty of talent out there to make it happen though.
  9. Wow! I have to try that. Even with 9 balls served. I already noticed the earlier BB game cartridges run a little slower. The ball speed is not as fast. Not sure why, maybe the different processors used??
  10. Has anyone seen this video talking about screen rot. I was trying to insert to a time in the video. scroll to 12:10 https://youtu.be/lt--fY3WOdk?t=729
  11. I have yet to clear a full screen on BlockBuster. 92 is my high score even with starting with 9 balls instead of the default 7. I had 2 blocks left! So close. Anyone else?
  12. vewy vewy close... I would think by next week the will start testing the protos in the 2 MV devices I sent.
  13. You can check you MV electronics with a good battery and the game. Start pushing the go button until you hears faint beeps from the piezo. You can test that at least.
  14. The Microvision LCD Project is back on track! 👍 Get this!! Apparently, when the 2 MV's arrived at the supplier, the entire eng team was OOT on another big project. So, the project management group went ahead and tried to get the project started. They tried "many many many times" to get the units powered on. The said the LCD's were "rainbowed". They were not working for them so they were about to give up. For over a week, many disparaging messages went back and forth and the project seemed doomed. With one final message from the project manager " it is too old lcd for us. " 😔 Then, the eng team got back. They took over. Powered everything up fine. Pulled the LCD's. Tested the only working LCD unit and the specs were known. TN type. 🤩 The second LCD unit was toast. It faded into oblivion. Which was expected. It was fading before shipment. What an unbelievable turn of events! 🥳 So, sample money has been dropped 🤑, the LCD spec has been created, drawings made, 2 sample types are being build. They will drop the sample LCD's into the 2 working MV's electronics for testing. Then, send some videos. If everything is acceptable, samples will be shipped for further testing. Stay tuned for another exciting episode of... Are those Microvision LCD's done yet?
  15. Ok, well that tells me more that these LCD units are not so fragile and should have survived. I've had good luck with cleaning up the contacts around the LCD and the zebra connectors to get a faded line of blocks working better. That could be worth a try on some of the bad units. Semichrome polish diluted with isopropyl alcohol works very well on the thin zinc coating on the contacts to the LCD and the cartridge connector. That connector reminds me of the nintendo 8bit connector that was famous for going bad. Remember having to blow on the cartridge before inserting.
  16. So you have shipped MV's overseas with no issues. Puzzling why both were so temp damaged? Maybe they sat in a hot truck or shipping container??
  17. I'm just guessing. I'm trying to talk to other suppliers on how these ship these.
  18. Sounds like it might work. I'm not sure what happened. Just both LCDs leaked out.
  19. There's been a huge setback. 😡 The 2 units sent to the supplier were "rainbowed" on arrival. 🌈 One unit was barely working when it left and the other unit had a very clear LCD with no sign of leaks. Both were DOA upon opening. They can't replicate the LCD unless they have a working unit to test. I've confirmed that with 3 different suppliers, unless you can completely spec it out for them to build. They all require at least 2 samples and the device if possible. The next step is to send the last working LCD by itself somehow protected from not only temperature but pressure changes. Cargo holds have extremes of both. I'll talk with a DHL rep to see if they have packing suggestions. 👍 🍻
  20. The screen will install exactly the same way the original one did. The costs are still up in the air until they actually make one test it out. Then create a batch of samples to further test in the 2 units provided. Then they will quote exact pricing.
  21. I just saw that website today. I was blown away the cartridge detail when all the work they went into it. They even had the keys labeled and new stickers put on the cartridge. It was really a great job.
  22. I found the pics in his posts. I tried to do a quick search but there are so many posts I couldn't find it quick enough.
