You can still buy
a subset of
chips designed in the 70s if you so desi
Hence stories about NASA having to scour eBay for some parts need for
maintaining legacy equipment.
NASA tends not to use off the shelf parts.
The ones in question are, otherwise they'd not be on eBay [as a result
of someone breaking up some old equipment and selling whatever they can
dis-assemble as spares].
Often they are things as boring as specific versions of a generic
processor or memory chip, which come in thousands of different variants.
