Building a Sixty-Clone ? Use the right chips!

Post by eslapion »

Finally, somebody made a video about CMOS vs TTL logic chips and fake Chinese chips.



So, if you build a Sixty-Clone: DON'T BUY ANYTHING FROM CHINA! Get your chips from an official distributor such as Digikey, Mouser or Avnet.

Make sure you use the correct logic ICs and these are 74LS or 74HCT

I recently noticed other people on various forums building 1581 drives from cloned circuit boards. Apparently some were affected by fake Chinese chips and had to deal with negative consequences.

Avoid Amazon and eBay at all costs when it comes to logic chips.
