View of my bedroom circa 1980. This could be a spot the MK14 competition! Look in the top right hand side of the picture (behind the Nascom 1 keyboard and power supply), and the white wooden box is it!
Check out the paper tape mass storage system too - 5 bit yellow tape and punch in bottom right hand corner.
Here's a zoom of that, showing the MK14 in its wooden box, with a cut-out to see the display. The replacement keyboard I made is half visible to the right (bottom half obscured by magazines).
Fast forward 26 years, and here's a view of my living room coffee table with the project in progress. I'm checking the components ready for return of the PCB. New components top left on top of net-checked schematic, some components on layout drawing, and SC/MP and INS8154 in anti-static box.
Zoom-in of that, showing original 1970s calculator display (another eBay purchase) and the 2 key chips.
Here's the layout of the original board...
And here's the new one.
