Unless one wants to do months of wiring on an adams-smith....mts1000 or ats500 are the name of the game.
238s mirror setup sync layouts of their former bigger brothers such as multiple tsr8s, 58s, atr60-8 etc. All of which I worked with.
Two 238s can be syncronized for 14trk operation via either mts1000 or ats500 along with two acc2 cables (each running to the synchronizer) and rca cables connected to each of the 238s' chnl 8 ports in and out. You'd designate one 238 as master, the second as slave. You'd select "ext" on the front panel of the designated slave as it's the one that will chaselock.
Setup procedure-wise, you'd first stripe smpte onto each 238 trk8, disable dbx on each trk8 (via back switches), set the baud rate on each to match baud rate on the synchronizer, and then run the synchronizer through its setup procedure to establish communication/learn/teach and finally synchronize all machines.
You'll then have a 14trk cassette.
I bought one of the first 238s to test back when they were first released in 87 or whatever.
While interesting at the time, I'll remind anyone who records one thing at a time that....using a single track of a current existing cassette machine....lets say a 202mk7...with no particular synchronization....as the front end of a signal (say a mixer)...and then routed to a mono input of a daw.....will give the same sound. A 14trk cassette sound on 14...or 1400trks of your daw. All while avoiding "rewind". You'd sorta have to nudge incoming tracks around to align once in the daw, but the idea is the same. You could even re-route tracks back through cassette a few gens. An analog mixer/console in between would be helpful for a bit of additional circuitry smear if you're gonna go down a few gens in the process.
