oh hey, I almost forgot, I still have the SVI-2000 robot arm if you want something else for the HOPE exhibit or the NYC MakerFaire. http://www.theoldrobots.com/images58/Robotarm-w1.JPG But I'm not sure if I can find the cartridge, it plugs into the C64 User Port. But it's very easy to make, all it was is a 4028 decoder with a row of output transistors. They get switched on/off by the software and it connects to both joystick ports on the robot arm . Personally, on something this slow I would use relays to keep it Retro. Nothing like hearing the clickity-clack on vintage hardware :) Because the bipolar transistors just suck up power away from the robot motors. So it runs slower than normal. This was originally made to use a pair of the popular joysticks, such as the Atari or C64, so it had direct power to the motors. If you want to masticate on it further, then Mosfets are the best. I could whip up this cartridge on wknd. Just have to find a case later. Oh and bring extra batteries, they go fast on a busy day. I don't know if you can find the original software, but they have one here http://csdb.dk/release/?id=122345&show=summary and here [german] http://retroport.de/Hardware_P-Q.html If you like, I can ship it, just have to find a big box at work, we have plenty of foam too - I'll just pick it up the next time I visit. I used it once at the Science center many years ago as a robot excavator inside a Martian landscape diorama. The martian rocks were painted chunks of styrofoam, and the dumpster rover was painted white with Nasa insignia decals. The kids had a ball. Dan
Would it make more sense to use optoisolators here? I'm a bit leery of connecting motors/mechanical controls with an independent psu and a decent amount of induction directly to a c64 userport for fear of having the CIAs or other more irreplacable chips let out their smoke if the motors are at the end of their range.

Good question The connection is as such User Port ----> 4028 ----> Relays ----> Robot Arm The relays already provide the isolation from the motor power inside the robot arm I would use optoisolators in any interface which used semiconductors as drivers, instead of relays, *even* when Mosfets were used as the driver. These days you can get optoisolators which include an internal mosfet driver. Dan
Dan If you think we can get it to work without the cartridge then ship it. Or if you find the cartridge then ship it. That would be a nice robot arm to exhibit! :) On Tue, May 24, 2016 at 10:57 AM, Dan Roganti via vcf-midatlantic < vcf-midatlantic@lists.vintagecomputerfederation.org> wrote:

03-Alex Jacocks-PS/2 model 70 and AT&T 6300 testing/repairs (Sunday)
Alex, do you recall the size of the HDD on the 3.1 machine that you loaned to us? Everyone else: Can we install 1.0 and 2.0 and 3.1 on the same machine? I'd like to keep it defaulting to 3.1 (easy enough), but it would be great if -- upon exiting to DOS -- we can change directories and fire up 1.0 or 2.0 as well.
Evan, The HDD is a CF card, in that machine, and so can be as large as is desired. However, I believe that the correct machines, for this exhibit (we have 2 PS/2 model 70s, at least, in the warehouse) would have had somewhere between 60 and 140 MB HDDs. But, given the limited size of the Windows installations (and DOS), these should not be a problem. - Alex On Tue, May 24, 2016 at 1:33 PM, Evan Koblentz via vcf-midatlantic < vcf-midatlantic@lists.vintagecomputerfederation.org> wrote:
