hp30b programming cables and clock/crystal/caps

[Dave Frederickson]

First of all, let me state that I'm a strong proponent of 3D printed parts, but it might not be the least expensive solution in some cases. For example, a housing for a Series 80 module costs around $60 USD if 3D-printed while a Series 80 HP-IB module can be found on eBay for $40 USD or less.

With respect to the 30b programming cable, most of the parts needed to fab a plug can be had for free from Samtec.

Can you point me to a schematic for your cable?

Data sheets and reference designs can be found at the FTDI website.
