Re: [M100] New Boards
Are you interested in sharing the PCB design files? I'm doing some stuff in an M100 case and I was just looking to start work on a PCB, and I'd REALLY rather start with someone else's design, rather than do my own from scratch.

Re: [M100] New Boards
Oops my bad S it¹s a fair copS. I think I have some blank boards left if you want to build one yourself. Just email me off line with your shipping details etc. Most likely I will not ship until after Xmas to avoid the mailing rush. It is quite a straightforward build if you are comfortable with surface mount components. I tried to use main stream parts the only Oodd' part is a Polulu power supply for the LCD, the contrast is controlled via the keyboard instead of a thumbwheel. I will throw together a Digikey cart too help with the parts selection, although you can buy most parts from your preferred supplier.

Re: [M100] New Boards
Great discussion. It's sort of like restoring a car or motorcycle. Do you do a "restoration" where the PCB is identical to the factory model with the goal of having a reliable copy of what came off the factory floor or a "resto-mod" where you just use the shell and all the internal are new with modern features? To me, I'd like a mix. No sense redesigning an Alpha Smart or something that already exists and has no connection to Model T. So what would be interesting is to reuse the Model T shell and have the PCB as close to original but a few upgrades so the user experience is the same.

OKI makes some really cool enclosures. Some that look very 80’s. Take a look at what they have to offer: https://www.okwenclosures.com/en another option is to look at kids toys from the 80’s to gut.

Re: [M100] New Boards
I agree, I'm intrigued by some of the possibilities of this. I've always dreamed of a "modernized" M100 that is just the size of of the screen, and you use it with a bluetooth keyboard.

Re: [M100] New Boards
The idea of a new PCB for the M100 has been percolating in the back of my mind for a while - primarily though because I'd like to reproduce the schematic in KiCad and nce that's done, laying out a new PCB would be "relatively" easy :) On Thu, Dec 17, 2020 at 12:29 PM Chris Fezzler wrote: > > Long time Club100 member here, more from the user side than engineering or > programming world. > > I see people are coming out with complete kits to build new versions of old > computers - including the PCB. > Economical?
