Thanks a lot Hi all and merry Christmas! Could you please reference the exact post? If it is the ebay one, we'd have to ask Daniel Schmatz because I didn't obtain those newsletters in printed form and the image above very much looks like a photo and not a screenshot. Still in touch with Daniel about the software BTW, so we might get a German version of Lego Lines some day. Quote

Sure you can use them for much more sophisticated stuff, but, also for talking/listening to Interface A! This thread is not about what can be done cheaper or less demanding, it is about what devices can interface to 9750! Your cards can do much more, but hey, I am absolutely sure that the chippies on these cards would be so happy when running 4.5V Technic machines. Is there a chance that you repost the card pictures? I have no idea how the Apple works on its inside, but I saw (but did not take screenshots, when I was preparing for a nice, 3 beers night diving into Apple ][ hardware) the photographs, all the chippies, I am familiar with ... of course these cards will do, I thought, but then - gone ... Man, I am using the I/O port of an Atari 1040 to talk to 9570. Believe it or not, I can hear some sort of "snickering", when it does. A friendly sound, though. This thread is about just doing or envisioning it. Best Thorsten Quote
Toastie Posted January 28 Author Posted January 28 Thank you very much @Gunners TekZone! It will take some time for me plowing through the (to me) unknown Apple hardware - but what is time! I love these chips. And others may be way more educated to come up with ideas, proposals, solutions. For sure: You can make it way less sophisticated, as said. On the other hand: You absolutely don't need an Apple or IBM PC/XT to control 9750. A ZX81 - the totally el cheapo Zeddy - is well suited to do so, with a little help from (again) dead cheap ancient TTL chips. Not the point: This thread is not about saving here and there, it is about making it work. If someone figures out how to connect a Cray X-MP to 9570: It is >totally< relevant to this thread! And most probably, I will faint. It is just fantasizing about what >could< possibly work, regardless of the approach. @evank will judge and approve or not, just for locking anything appropriate into his (wonderful!) website. How cool is that. But here on EB: Just go nuts. All the best Thorsten Quote
evank Posted January 29 Posted January 29 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: Quote
evank Posted January 29 Posted January 29 It looks like you're using 9V motors but 9750 only outputs 4ish volts. What am I missing? Quote

Hello, very interesting document. With an G850VS you have luck to have an PIO Harware on the 11-Pin Port With an 1401 you can write Data (for example by LPRINT) to an external Interface to use them for Interface 9750 But the 2 Inputs might than be accessable only by Assembler-Code (or Peek/Poke Subroutine) ... Is there a schematic drawing of the GV850VS available ? wher can I find ? Or is there a Datasheet for the SC61680 Processor available ? how operates Xin/Xout there (especially the 2kHz/4kHz Mode and how to read Xin frequency) Johannes Quote

I watched all your videos way back when, while awaiting for my 1st (and only) Interface-A to arrive. You have an amazing collection!! I too originally played around with coding some stuff in Commodore 64 BASIC before finding the English version of LEGO Lines. I recently acquired original 1090 "box/book" of instruction cards, and I think I have assembled all the needed parts from within my collection... One day, when feeling well enough, I will build one of the arms. I am curious how you can make a robot arm from the 1090 set knowing you have only two motors, All models I have seen use the 1092 set instead. How did you manage with those limitations.

How cool is that. But here on EB: Just go nuts. All the best Thorsten It would be awesome to have a single Apple II card that can control multiple Interface A devices! Then I can get back some functionality that I've had to remove from my development machine, so that I had enough 9767 cards for my most complicated projects. Quote
Toastie Posted February 9 Author Posted February 9 55 minutes ago, evank said: It would be awesome to have a single Apple II card that can control multiple Interface A devices! I believe the card @Gunners TekZone posted above (on the left) can do that. Two 6522's = 4 freely programmable 8 bit I/O ports: https://en.wikipedia.org/wiki/MOS_Technology_6522 The 6522 have more on board that you don't need at all for your purpose. All these features seem to be exposed on the multiple pins on top as well, I believe. Any chance that there are more of such cards floating around? I can't figure out the address decoding - and I have no clue how an Apple II addresses cards sitting on these bus sockets. On the IBM XT cards are freely addressable (with exception to ISA socket 8) but I don't know how that works on the Apple II. I have the feeling there is some socket dependent addressing (see card on the left, which is "socket selective"), but again, pure speculation here. Other know for sure better!

maehw Posted February 24 Posted February 24 I stumbled across this dead cheap Interface A listing on eBay from a seller in the US: ~21 $, unknown state, no power supply https://www.ebay.de/itm/336353044675 If I wouldn't already own one, I'd consider buying it. Probably not too attractive for Europeans though as shipping is expensive and customs these days probably, too. Cheers, Mäh Quote
Toastie Posted February 24 Author Posted February 24 56 minutes ago, maehw said: ~21 $, unknown state, no power supply Well, at about €18, there would be about €20ish for S&H + tax. I got my third recently from the US, and it was for €40 on BrickOwl. Total was €65 incl. S&H+tax, which I thought was a very good deal. It was in tested and perfect condition. As I have three of these now, I also don't consider buying it. As these are virtually unbreakable and even if, they fully made with nicely "desolderable" and replaceable parts. If I were looking for one, I would definitely go for it. Thank you very much for sharing!!! All the best Thorsten Quote
