It looks like you're using 9V motors but 9750 only outputs 4ish volts. What am I missing?

LOL - Cray. Juuuuuuuuust a bit overkill. It would be cool to see 9750 interfaced to that pocket computer! :) @Gunners TekZone in case you haven't seen it already, here is a video I made about the current 9767 options:

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.

I recently acquired several Control Lab teacher's manuals that are not scanned anywhere. So I am rectifying this. :) It's going to take a couple of months. Michael Mulhern (known in the Apple II community) is going to do the scanning on our behalf. Then it goes here: https://archive.org/details/vintagelegorobotics

Yes. https://archive.org/details/lego_c64_manual_basic_comal/mode/2up -- starting on page 5.

Archive.org's browser emulation can not connect to physical hardware. I confirmed this with Jason Scott, who built the emulator.

I rescued a large amount of Control Lab stuff last weekend. I was digging through it and found (surprise!) 5.25 Apple II LogoWriter Robotics. LOL I think it's hysterical to find that in the wild NOW after we all just got it a few months ago.

I rescued a large amount of Control Lab sets last weekend. It included the Intelligent House disk (for Mac) so I'll see about archiving that one.

(sorry I had to delete my reply)

This is just a heads-up to anyone who might be interested: there's now another option for fans of Interface A (1093/9750) to communicate, in the form of a Facebook group at https://www.facebook.com/groups/legointerfacea/. The group is not designed to draw anyone away from Eurobricks (I like it here!), just to offer an additional choice for people who tend to linger on social media.

Control Lab also has a DOS version. I know about the serial approach ... "Do you byte, when I knock?" ... "Just a bit, off the block" ... a friend helped make that connection to 9751 in QBASIC. Still, I'd like to know about the underlying software. Maybe it's buried in some Control Lab manual. I will look someday.

I know there are many software choices for operating 9751 Control Lab -- just as there are for 9750 Control Center -- but I wasn't sure which language is underneath the actual Lego Control Lab application. Is it still Logo? The irony of finally obtaining LogoWriter Robotics is that I have no intention of using it! I'm sticking with my favorite, good old BASIC.

That's mostly correct. LWR was introduced by LCSI, not Lego. I should clarify that on my website. I know Control Lab doesn't use Logo, but I'm not sure what it does use. @BatteryPoweredBricks would know best.

I and many other 9750 Interface A hobbyists have spent several years hunting for LCSI's "LogoWriter Robotics" software. There were plenty of false leads. The standard LogoWriter software and TC Logo are widely available, but nobody could find LogoWriter Robotics (which adds back features that were removed from standard LogoWriter.) A few years ago I was in direct contact with the original 1980s software developers from LCSI -- they didn't have it. People have tried reaching Lego corporate historians and many other promising leads, but everything failed -- until this week, when @amine discovered a year-old Reddit thread here: https://www.reddit.com/r/AFOL/comments/1f083cf/got_a_bunch_of_dacta_sets_including_an_apple_iigs/?sort=new Amine is in France, so he deferred to me because the original poster is just a few hours from me (New Jersey / Maryland). We're all incredibly lucky that the previous people who offered to buy it from him didn't pan out, and that the original poster got busy and forgot about it, so he still had it available. I spoke with him by Reddit chat, text message, and finally by phone. We made a deal for me to buy everything but the computer itself (I have enough Apple II gear, and I didn't want to ship a full computer that I didn't even need.) He sent me a couple of 9767 cards, a 9750, etc. -- the usual stuff you find for that generation of Lego robotics -- but most importantly he send me two copies each of the 3.5 and 5.25 disks, plus the LWR manuals. A couple of other 9750 hobbyists helped me fund the acquisition (I'm not naming them; they're free to identify themselves if desired.) A friend not on this forum lives near me and owns an Applesauce archiving system, so he's going to properly archive the software -- I was not going to just fire up a super-rare disk and see what happens. That's too risky; what if my drive ruined it? However one of the 5.25 disks was someone's backup copy, vs. the original, so I felt safe trying that since the original is here too. It booted right up! And of course I immediately copied that backup disk, to have a third copy for a fail-safe. When I have some time, I'm going to put the .dsk files and scans of the manuals into the Vintage Lego Robotics folder on Archive.org: https://archive.org/details/vintagelegorobotics Here's a picture of LWR running on my Apple //e tonight: https://drive.google.com/file/d/1skiB5yMVc_1F-67dh0D19pJiU0GbepI5/view?usp=drive_link.
