How many shift register stages could you get in a chip in 1969?  Four?  Then you'd need 8 chips for the Muse shift register.  Was the 74164 8-bit shift register available?  Maybe not.  Judging from the board layout, those three 24-pin packages seem to provide 10-bits of shift register each.  I don't know what those could be.<br>

10.  :-)  Those 3 large chips are 10-bit shift registers. Markings<br>
on the chips in my Muse suggest house markings so that's not promising.<br>
But the functions will all be SSI-level.  Haven't checked voltage<br>
levels but devices may not be TTL...<span class="HOEnZb"><font color="#888888"><br>
