Digi-Key still lists the 75160 & 75161 chips available in stock fairly inexpensively ($2.79 each) quantity 1. The TMS9914A was a bit tougher to find, but National Instruments offers a drop-in replacement chip, the NAT9914. They are available, but all I could find was offered through their website, and a tube of 9 costs $149.00 However, unless I'm mistaken, you're in South America, are you not? I would have no idea of the availability or ability to ship these units to SA. I did find on ePay that there's a Chinese seller has the PLCC44 version of the chip for $12 each with $5 shipping. The feedback seemed OK, but... A PLCC44-DIP40 adapter shouldn't be too hard to build if you're good with hardware & a soldering iron... Hope this helps! Roger "Merch" Merchberger
