Re: Need help reverse engineering Timex Store Demonstrator ROM file

XavSnap and the rest of you, The board is still a no go for a direct connection! :( Unless you continue to use a printer connector with the particular board. :| Look at the zipped folder of pictures. I used some tape to simulate temporary soldering. Please add a centimeter and a millimeter (11mm) to...

Re: Memotech Memopak 16 'through pcb'

Kbjunkie,

You are correct. I am in USA. The British pound values more money than the American dollar. :lol:

Re: Need help reverse engineering Timex Store Demonstrator ROM file

XavSnap and the rest of you, I just received the Timex Store Demonstrator board, issue 2.1 reversion today (10/27/'22), and an extension board from a carrier. I tested the board with a continuity probe, which was designed for testing the electric water heater, for the voltage feed. The ICs' V+ and G...

Re: Need help reverse engineering Timex Store Demonstrator ROM file

XavSnap,

Yes, the TRACO will work with its long body laying down flat. Expect to add three little copper wires to the converter's legs. Or, I would put a DC-DC converter on the other side of the particular board and match the converter's dot to the board's 9vdc hole.

Cheers,

Re: Need help reverse engineering Timex Store Demonstrator ROM file

XavSnap, As I viewed one of your recent gifs, I noticed there is enough headroom which satisfied me. I definitely would order PCBs after the edge connector's slightly enlarged holes mentioned by you, XavSnap, in the Kicad/Gerber file. I take care of the DC-DC converter's position. I also want a "fin...

Re: Need help reverse engineering Timex Store Demonstrator ROM file

Hello everyone, XavSnap is right about my StroeDemo card readiness. However, it has some problems which require getting two sockets two pieces of wire, and some little black electrician tape to correct the voltage reversal feeding problem and using a printer connector or an extension cable to give E...
