I've been sourcing parts for the multi calculator and I believe I can put a kit together for about $Aus50.00 + postage.

I can build and test the calculators for those who don't have the expertise. The finished kits will be just the circuit board so either adhesive feet can be stuck the board or a case would have to be made. Maybe a simple clear acrylic top so that a key layout could be fitted.

I don't wish to make a profit on the kit, so the price is what the parts will cost me.

If anyone is interested, let me know and I'll start work on it. I'll need a minimum of 10 to keep the cost to a minimum as some parts have to be sourced from different suppliers.

cheers

Tony
I would love to know more before I decide to add my name to the list.
The questions that come to mind are:
1. How much does the kit cost? Cost with assembly?
2. Does the board require an old HP calculator to complete the kit?
3. If so which old HP calculators are compatible with the keyboard spacing?
4. If it is compatible with an HP-35 and HP-45 then how can it be compatible with
and HP-25, because the two are very different in keyboard spacing and size?
5. Do you need to provide your own display? Display drivers? Display board?
6. Do you plan to offer a complete calculator kit including display, keyboard,
I realize that a case is beyond the capability of home-brew kit designers, but
if it resembled the NP-25 board for example where it was a fully functioning calculator with buttons and display, but no case that would be very nice.

I only ask these questions, because from the descriptions in the thread thus far
it is not obvious what the kit includes.

Thanks, Barry Mead
