[committee] Wire wrap and other prototyping

[Harry]

Hi Sam (etc)

Can do. What date ? A calamity is that the little adaptor boards I have been
using (SO8, SOT23, etc to DIP8) are discontinued from SoanarPlus. I'm just
finding out now what is available.

Manufacturer is Bellin Dynamic Systems:

Ok, Mouser still has them:

If you let me know the stepper driver chip package you were using (was it
TSSOP28 ?) I can get one of those from you and set it up on an adaptor board
(if available) to show a different approach rather than soldering to the SMD legs.

All the best
Harry
