Full Writeup: http://www.glitchwrks.com/2016/09/12/lego-logo-interface Ian was going to build the interface, but since I ended up having to troubleshoot the suspected flakey hardware after The Eleventh HOPE, I went ahead and built one to have a known-good board to test with. This uses one of the new Apple II protoboards I laid out a few months ago. I may either reduce the hole size or increase the annular ring on the pads. Right now you can stuff two 24 AWG solid wires plus a socket pin in the holes, which is great for point-to-point prototyping. It'll also take a through-hole switch or 2 Watt resistor without drilling out. About to run out to the post office and send it on its way to Evan! Thanks, Jonathan

Nice work Jon One of the things I noticed was how the early Lego revolution never spanned across the home computer market. So many other computers would take advantage of this. It appears it was primarily focused on Apple alone at first. As usual they probably worked out some marketing deal to prevent that. The only other it seems was the IBM PC who was afforded this interface - mostly likely because that IBM was just as popular and it's name recognition. I recently picked up a couple of Lego 9750 interface boxes which attach to the computer. Mainly because I wanted to use this on the Commodore. Because I saw that you don't need any additional hardware as on the Apple or IBM. The User port already contains the PIA hardware which the user can program for this interface. All that's need is an adapter cable. And the User port is available on most of the early Commodore computers, from the PET to the C128, maybe others too. So I was working and adding this to the C64, then later to a PET8032. Just add software and run. Dan

My 2 cents .. The Lego kit was probably expensive and focused on the education market where Apple was king. -- Linux Home Automation Neil Cherry ncherry@linuxha.com http://www.linuxha.com/ Main site http://linuxha.blogspot.com/ My HA Blog Author of: Linux Smart Homes For Dummies
Neil, agreed. This was marketed exclusively at the education market. Also, it is possible to use a standard PC parallel port with a custom cable to interface with the box: http://www.lgauge.com/technic/LEGOInterfaceA/9750(1093).htm On Tue, Sep 13, 2016 at 10:16 AM, Neil Cherry via vcf-midatlantic < vcf-midatlantic@lists.vintagecomputerfederation.org> wrote:

yes, Apple was king in the Education market But after they spent thousands on the Apple 2 hardware, The schools were often cash strapped to buy anything more hardware. Perhaps just one Lego kit which they all had to share Nothing's changed, same problem as with the Lego Mindstorm I use to volunteer for the school's robot club Dan -- _ ____ / \__/ Scotty, We Need More Power !! \_/ _\__ Aye, Cap'n, but we've only got 80 col's !!
