<p>Scotchflex is definitely a blast from the past!</p>
<p>Nowadays with memory on-chip with the CPU and single pin serial
interfaces commonplace, there just isn't demand need for such a
prototyping aid.</p>

<div>Just as an aside, it looks like your prototypes suffer from
the same issue mine do - they lose their 1488 and 1489 chips
to the sands of time as other projects need them. :-)</div>

Sure, here is a Scotchflex prototype.<br>
<br>
Typically, when one was trying to build something that was
going<br>
to be alpha'd forever, then the 3M press strips would be
soldered<br>
directly to sockets on the bottom of the perf board. The wire<br>
is the exact same stuff used for wire wrapping. Dabs of epoxy<br>
would be used to bundle everything together.<br>
<br>
Its very handy.<br>
<br>
In the case of microprocessor designs, all of the boring,
normal<br>
and necessary stuff like the ROM/RAM/decode
logic/clock/UART/Interrupt<br>
Controller/VIA, etc. had to be banged off fast. This is where
the<br>
Scotchflex is amazing.<br>
<br>
A prototype would be worked until it was perfect.<br>
<br>
Of course, its not possible to do a commercial release based
on this<br>
stuff. A wire wrapped board, on the other hand, is fully
releasable.<br>
<br>
I am still coming to terms with this era being over as of
yesterday.<br>
Similarly, I always thought it was fancy to one's own circuit<br>
boards printed and now I am going to do just that.<br>
<br>
I somehow missed the news.<br>
