You'll also need the Wozmon PROM chips. You can get a set (2) of eBay or make your own breakout board that uses a modern EPROM chip such as this. I think it's easier just to get the eBay one for $20 since they come programmed with Wozmon (the A1 and A2 PROMs...A3 and A4 are two other PROMs that are used in the cassette interface board if you decide to add one).
The 2519 shift registers are hard-to-find nowadays. You can still get some eBay for about $65 here or use a breakout board such as this. I haven't used the breakout but it looks pretty cool. The CM2140 is a character generator. It's basically a pre-programmed PROM. Those you can get on eBay but I think the 2513 is cheaper and can be used instead of CM2140. They're also on eBay between $10-20.
