HP-5036A Microprocessor Lab

Good evening

If these count as very old HP computers, I'd like to share information on the internal plastic hinges and fasteners that attach the PCB to the briefcase. These deteriorate over time, but with the aid of 3d printing (hinges) and because Southco are still making the Nylatch fasteners 50-odd years later, they can be readily refurbished.

Courtesy of Pro3DShop in Holborn, London (https://pro3dshop.com/pages/contact), I've attached a .stl file for the hinge pieces.

The relevant Southco latch part numbers are (see pdf attached):

NY-5P-53-1-50 (plunger)
NY-5G-53-20 (grommet)

Thank you,

Andrew

I also have Intel 8080, 8085, and 80386, a Motorola 6814(?) SDKs.

I remember using a genuine Intel 8085 board (SDK-85) to learn about that CPU and interfacing to other stuff. Later a Zilog Z80 based CP/M system. The Motorola chips of the time always made more sense to me.
