Spoiler And of another kind of course: In our PChem lab for second year students, we do fractional distillation (some call rectification) of a three component mixture of liquids having close boiling points. When I actively ;) took such a lab 40 years ago, uhm, we exchanged the multi-component mixture with denaturated ethanol. Back then, pyridine was frequently used the denaturation compound. Well, the 2 m rectification column in the PChem lab was well suited to quantitatively separate these two, resulting in a 96% ethanol/H2O mixture. Upon addition of some tonic water etc. ... Thank you very much, Evan! All the best Thorsten Quote
evank Posted January 21 Posted January 21 You're welcome. A few weeks ago I happened to see on Facebook Marketplace that someone a couple of hours from me was selling a massive haul of Dacta sets. He wanted a substantial sum. We negotiated a deal and I drove out there. I don't need most of the sets (so I'm trying to sell them: https://www.eurobricks.com/forum/forums/topic/212437-fs-several-early-dacta-sets/) ... mostly I was willing to lay out the money because his stash of rare Lego educational manuals was overwhelming.

legoROBOLAB Posted Monday at 08:59 AM Posted Monday at 08:59 AM This is a great step towards the universal use of interfaces, namely B. I greatly appreciate your work. Continue, The last LEGO Education product, to be released in September 2026, has an identical type of language. This is modernizing the old LEGO sets. Thank you again. Quote
amine Posted Thursday at 05:16 PM Posted Thursday at 05:16 PM (edited) I am getting the german version of lego lines for IBM soon. I have no clues if the package contain the disk, maybe Just the manual..... If by any chance we get the disk, this will allow us by comparing the French and German versions to make a perfect English version. But the french and German look very similar if not identical.

There are some additional op codes, but that is very well documented in the NQC software, which bundles with the current BricxCC framework. And also in the LEGO SDKs documents for all the original Mindstorms platforms. The CM came before the RCX, but shares a lot of the programming infrastructure. As discussed extensively in another thread here, you can connect to a CM using the RF tower with a simple terminal program - after initialization. Again NQC/BricxCC documentation has all the opcodes. Hope that helps + all the best Thorsten 1 hour ago, AJB2K3 said: like and RP400 or RP500 Wow! That is a nice one! When wanting to integrate the Interface A into your suite, you'll need 8-bit parallel outputs (2 input 6 output). It appears as if the 40 pin GPIO port can do that with no hassle. This is different for all other interfaces and PBricks; they run on serial hardware. But I believe you know all that. Cool project! All the best Thorsten Quote

I'm working in OSX so it needs an Arduino to act as an adapter but then the Arduino+interface A will be treated as an Interface B. I never considered direct running from the RPI but again I do believe that the I/O pins were measured @12V so an adapter is still needed (don't have one to varyfy.) I got the Interface B running with a simple python program first, then sorted on the other functions then got board and built the IDE. Edited yesterday at 06:13 AM by AJB2K3 Quote

maehw Posted 15 hours ago Posted 15 hours ago Great news I am reading here. However, I'll need more time to really read and answer things here carefully. Especially excited about LEGO Lines for IBM PC. About the RCX: a quick reminder that I've done this thing called WebPBrick (.com + GitHub). Also with a visual IDE (Scratch-alike, i.e. Blockly based) to generate NQC code. And the compiler running in your browser and download the programs via WebSerial and maybe some day also WebUSB. Cheers Quote
