Being of a young age and of less sound mind, one of the ‘treats’ was keeping the button pressed to watch it turn to zeroes at midnight! Hey, it was the age of 80085 on calculators!!https://community.element14.com/challenges-projects/project14/circuitprototypetechniques/f/forum/50893/wonderboard-solderless-circuit-cards/197189Sat, 09 Apr 2022 05:46:00 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:bd81949b-8586-4370-a9a7-6c7da9d28239dougwI remember Speedwire but have never heard of Wonderboard. Back then I couldn't afford any type of breadboard system - they were just the stuff of dreams.https://community.element14.com/challenges-projects/project14/circuitprototypetechniques/f/forum/50893/wonderboard-solderless-circuit-cards/197182Fri, 08 Apr 2022 14:53:00 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:b410b827-5595-4d8c-9c62-d9b6c83d6b27scottiebabeYes exactly, and the pen just had a spool of 30 awg Kynar wire on top. Yes the eurocard was definitely large enough to contain an entire project on one card. I find the inexpensive 5cm x 7cm perfboards are often too small, but they are soo cheap lol. I :heart the pico, it so easy to get a project started in micropython, and if you really do need performance you can always code in c if you want. For example I just wanted to blink an LED every 30 s, it was too easy to just grab a pi pico and write a few lines of python.https://community.element14.com/challenges-projects/project14/circuitprototypetechniques/f/forum/50893/wonderboard-solderless-circuit-cards/197181Fri, 08 Apr 2022 14:47:00 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:fa057c58-dd1c-4c9b-a580-eededaa61abdshabazCustomers were also paying for the number of digits on some of the models : ) The 6-digit watches (with seconds) are advertised with 6-digits being a differentiator over 4 digits : )https://community.element14.com/challenges-projects/project14/circuitprototypetechniques/f/forum/50893/wonderboard-solderless-circuit-cards/197178Fri, 08 Apr 2022 14:13:00 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:a8f4238e-89bc-4213-9edd-198c5ad61e06shabazNice! It looks like IDC style pins like on the rear of phone jacks.. If you could find a source for the metal contacts in IDC ribbon cable sockets, then those might work : ) I really like Eurocard, I wish it was cheaper and more popular. A source for single-slot or double-slot+backplane enclosures would be nice too, but I can imagine those are not cheap. It's the perfect size for prototypes.. maybe even a half card or 2/3 option would be great. One thing I wanted to make (have not got around to it yet) is a Pi Pico board with just the Pico on it (and a few ancillary bits to make it easy to use, like power connector, space for voltage regulator etc, and a load of perfboard area, perhaps Eurocard size. It's fast become quite a popular microcontroller board for me, because it's in-stock : ) also easy to code with.https://community.element14.com/challenges-projects/project14/circuitprototypetechniques/f/forum/50893/wonderboard-solderless-circuit-cards/197177Fri, 08 Apr 2022 14:07:00 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:f30a9285-7e9b-41ec-a284-7e896a1ffdb8Andrew JYou’re right. £179 in 1978 is worth around £1100 now!

I wish I had a speedwire board just as a collectors item https://en.wikipedia.org/wiki/Speedwire This was the best photo I could find after a quick search https://docs.rs-online.com/e9b7/0900766b800270c2.pdfhttps://community.element14.com/challenges-projects/project14/circuitprototypetechniques/f/forum/50893/wonderboard-solderless-circuit-cards/197174Fri, 08 Apr 2022 11:00:00 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:c9bada9c-0197-45da-b966-cb32a09423e4neilkAdjusting even vaguely for inflation, the Quick test and Protoboards look very very expensive!
