S-100 IDE Board & TIL311


Looking ahead to the S-100 IDE board (http://s100computers.com/My%20System%20Pages/IDE%20Board/My%20IDE%20Card.htm) I see that Jameco still has the TIL311 in-stock.  https://www.jameco.com/webapp/wcs/stores/servlet/ProductDisplay?storeId=10001&productId=32951&catalogId=10001.  However at $20 each, with 6 on the board that's a pretty penny investment.  Even a bulk-buy, if folks are so inclined, doesn't improve the pricing much (might get down to $16 but not less).

You note that UTsource (http://www.utsource.net/ic-datasheet/TIL311-421656.html) has carried them in the past (apparently themselves, rather than from various suppliers?) at ~$4 -- I haven't checked current availability as yet.  Have you checked for a recent quote?  Are they reliable?

Any new(er) thoughts regarding an alternative solution that might be more affordable, or are there any other well-known suppliers that are significantly less expen$ive than Jameco?

(Is there an Octal equivalent to the TIL311 -- aside from cutting off a pin :->?  Just curious ...)

Also, please make sure to sign me up on your reserve list for the S-100 IDE board :->.

Hi Benno!  Thanks!  My plan is to get the S-100 IDE and S-100 ZFDC board
PCBs next and then the S-100 backplane PCBs.  Hopefully this will happen
this winter or maybe early spring of this year.

Thanks and have a nice day!
