I would imagine that the LS chips are expensive because they are obsolete. I used them because they were in my junk drawer. I would recommend using the HCT series. I see that the pin names have changed a bit from the old datasheets.

Gene, Not sure if you would be interested in the approach I'm using, but it may help you or others who are in a similar predicament. You can use shift registers to add as many additional lines as you want. For example, you can take 3 output lines on your parallel port, and turn them into 8, 16, 24 or more output lines.

Re: [Emc-users] Help, out of inputs on my parport
Also, there are lots of TTL to USB and RS232 converters already assembled on Ebay - very cheap. Cheap until you check the shipping... :( I've almost been caught out by this a few times - sometimes the shipping is reasonable (or free), sometimes the shipping is more than the cost of the item. It pays to read the fine print - especially when there are 10+ identical items with different shipping amounts listed. Nah, shipping is often free from HongKong; it just takes a while: Oddly enough I've had more problems getting shipping from the US to the UK than from Asia - Two parcels, ordered within a day of each other. The first (from Mesa Electronics) arrived in 4 days. The day after I got the demand from customs for duty - somewhat unusual (Usually customs here hold the item for about a week, then send out (via second class post, which takes another week) a demand for payment backdated to when it arrived in the country) The second parcel (from another supplier) didn't arrive well, so I thought - contacted the seller and got a refund. *Three months* later, it arrives - checked the postmark - which was the day I ordered it, checked the shipping method - USPS first class. Then resent the money to the supplier, exchanged a few jokes about USPS and shrugged. No demand for payment from customs on this one... yet. Items from Asia usually take about 5 days (for small airmailed items) to 3 months (for larger items) - what happens when it hits customs is anybody's guess. -- Master HTML5, CSS3, ASP.NET, MVC, AJAX, Knockout.js, Web API and much more.

[Emc-users] Help, out of inputs on my parport
Greetings all; I went out to see if I could get this little sparkfun electronic fuse hooked up this afternoon ran into a tall granite wall impeding any progress. I am out of input pins on the cnc4pc C1G. But I do have a low use pin, reserved for a G38.2 probe I intend to use as an auto-touchoff probe at some point. Can anyone suggest a block diagram for the hal file that would use this input for the g38.2 function when a G38.2 is actually running, but when it is not running a G38.2, its an ESTOP in? Thanks for any clues. Cheers, Gene -- There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
