Up for sales is one set of fully assembled and tested GEN2 Apple cassette interface (ACI). I will also include two 30cm audio cables for the two ports (TO TAPE, FRM TAPE) and a brand-new cassette with BASIC on one side and blank on the other side so you can saving your Basic programs. Reading and saving become so much more reliable that you will enjoy loading and saving your programs in cassettes just like the old days. The interface has the very useful Extended Formatting page PROMs from Bernie. I am offering the assembled board as long as I can get 2K PROM ICs.

If you would like to assemble the board yourself, you can also get the bare board from my other listing. Free shipping worldwide.

No one is better than Bernie himself in explaining the GEN2 ACI, below is abstract of his post in Applefritter.

"... My Gen1 improvements fixed the "volume indicator LED" circuit,  added a synchronizer for the read data, and gave the ACI the capability to use 512x4 PROMs in lieu of the 256x4 PROMs of the original ACI. I added an "extended format page" which gives the ACI the capability to write and read Apple II cassette recordings and also do autoload and autostart recordings for the Apple-1, including checksum checks. Out of respect for Woz, I did not change his original ACI code to accomplish that. The "extended formatting" page is just an add-on you get when you start the ACI firmware at $C500 and not at $C100. If you start at $C100, you still get the unmodified ACI firmware as written by Woz ....

These Gen1 improvements worked OK  as long as a good quality cassette  recorder was used, or, if AIFF or WAV files were played to the ACI via a sound card of a PC or notebook (or iPod, etc.). But it still had the fundamentally flawed TAPE IN circuit of the original ACI.

My Gen 2 improvements kept all the Gen1 improvements as they were and changed the TAPE IN circuit for a much, much better one which is in par (readback reliability wise) with the Apple II cassette interface (but does not need any negative supply voltage, so these Gen2 improved ACI cards also work in the Briel Replica-1). My improved TAPE IN circuit adds a few SMDs hidden under the DIL-8 socket of the LM311, and re-uses the exising leaded, vintage-looking resistors (but the circuit is much different). So the "looks" are preserved, compared to the original ACI...."
