Hi Ken, no worries on the speed of the reply, we all have busy lives, and you certainly have your hands full. So, would 1 year be a sufficient amount of time from now to get evereything together? that's an hour a day, or 8 hours a week. we could strech that out if necessary. I think, also, that there are pcb houses who can replicate boards from an original pcb, though the new connector would have to be arranged for. John's idea of a 3d printed case is valid, but I'd vote for the original case design instead. just me. Best of luck in China!

If we were going to do another run of NADSBoxes (and possibly REX) via "group funding", I would want to set it up as an official project with a schedule, milestones, etc. Particularly expectations on return-on-investment for anyone contributing to the fund. When it was just me spening my own money (and even more than that, time), it didn't matter when or even if I ever got it done. But that changes considerably when other start to have real money involved. When I did the original run of NADSBox, I was effectively single with no kids (they had moved to a different state). So I had an abundance of time on my hands. Now I am re-married with two kids ages 5 and 3 and I have a building full of ASIC engineers who report to me. To me, my time has become more valuable than money (never thought I would say somthing like that! :) Deveoping the original NADSBox took 2,200 hours. A second run wouldn't be *nearly* as much time, but it would take on the order of 300-400 hours. This is because I no longer have a PADS PCB license and must re-do the layout in Cadence Allegro. A project schedule would look something like: 1. Check for parts availablity (I know the PIC is obsolete but still available). 2. Select a new SD card socket 3. Redo the PCB layout (this would be identical layout, just in a new CAD package). When I tried to import to Allegro, it sorta got there, but all of the net names were lost and it shows thousands of design rule check (DRC) errors. DRC count should be zero. 4. Do a small test run of 5-6 PCBs to validate the "new" layout. 5. Program and test the new boards. Validate they fit in the existing NADSBox enclosure. 6. Make any necnessary changes to the PCB if it doesn't work. 7. If needed, do a second run of 5-6 PCBs to validate the potential changes from #6 8. Make any necessary changes to the enclosure diagrams and have new enclosures built. These were done by Serpack in the LA area and have a 3-4 week lead-time. This is largest expense of the project in terms of cash. The setup fee for pad printing and machining is on the order of $2,500 alone. That doesn't include actual price of the enclosures or the per-unit cost of performing the machining (these two together probably add up to $23). The setup fee is amortized over the number of enclosures you purchase. 9. Generate instructions, software and tools so a PCB house can perform programming and testing of the boards. 10. Get a PCB house to manufacture, assemble, program, test the PCBs 11. Provide enclosures to PCB house along with mounting screws, etc. and get them to assemble the final units. With a bit of Steve's assistance I could manage getting the board house to do assembly and programming of REX also. We would probably want to change the Gerbers such that the PCB edges are true castellated edges instead of needing to be hand grinded. There are PCB houses that can do these cleanly with the proper copper clearance from the edge of the PCB and liquid solder mask rules.

If you don't think rex is as an attractive an idea, I'm willing to bear that burden alone, and we could split nads and woolly costs between us.

Here's my take on things: NADSBox -- I think there probably is quite a bit of interest in this product even today. I'm willing to bet there would be at least 10-15 immediate pending sales on this given the interest I've seen on this list alone. REX -- This might be interesting as well, however it sounds like WOOLLY would likely be a better place to put engineering effort & dollars. WOOLLY -- I'm betting the majority of folks on this list would likely want one of these. If I had to pick only one product alone to focus on and bring to market, I'd pick this one! REX functionality, RAM expansion (for CP/M), and WiFi capability. All of that would be amazing to have in one piece of hardware that can fit into an Option ROM socket. We're talking about a potential replacement for all of the ReMem and REX variations that existed previously, and then some. I'm willing to contribute significantly to the effort to bring any and all of these products to life (for the second time for REX & NADSBox of course). And when I say contribute, I don't just mean encouragement & testing & labor. I'm talking about financial. :) Probably the areas I can best help in would be fronting a good chunk of the costs for sourcing of parts & production, and then also on the eventual fulfillment. (Either hosted on Club100.org or on Web8201.net or some other central hub, doesn't matter. I can definitely assist on the eCommerce end.)

I would have to get a cashier's check and mail it to you, because I can't pay that much by paypal all at once. Maybe I could paypal it to you over the course of a week.

This is when I was having them built and assembled in China. I probably still could have them built and assembled there, though it is a bit more challenging since I no longer live there. Turns out I am traveling to China next week and will be visiting Shenzhen for 5 days! YEA!!! Maybe I could visit my old haunts while there (in fact I am looking forward to it). One of the concerns with NADSBox is that I need to update the layout a bit to select a different SD card socket ... the socket used in the last round of NADSBoxes was acquired from a Chinese source with no real part number or way to track it. So the footprint is specific to that part which is no longer available. I am working actively on Woolly which would replace REX and in a way, NADSBox, via TPDD access to a host via WiFi. But this is still a big development effort, both in terms of hardware and software. If you still wanted to put up the cash after reading this, we probably wouldn't need to build 240 NADSBoxes as demand isn't what it was in 2009, but it would still be in the $8K - $9K range I would guess for NADSBox alone. I don't know for REX. Ken On 7/28/17 7:05 PM, ray gordon wrote: I'm willing to put up the cash necessary if Ken & Stephen would be willing to do another run of NADS & REX.
