A friend of mine from the Apple I Mimeo website, Mike Willegal, alerted us that a specific transistor may be in short supply. The normal production and stocking of MPS3704 seems to have stopped with major distributers. I showed Mike there are some suppliers out there which stock this part. however, the future availability of this transistor is unknown.
Here’s a few sources for this transistor which I found so far. I’m not sure about the date code.
