Title: Installing RapidRoad on 1200 with full-sized clock port
Post by: LoadWB on February 23, 2017, 08:51:32 PM
The short clock-port header which came with my RapidRoad will not push down on the clock port as all of the pins are present.  Does anyone have a way to get this done easily without me having to hack up ports or cables?

Well you'll have to modify the cable. Either drill holes for the next pair of pins or replace it with one that fits the clockport... I suppose a 44pin part from an old 2.5" IDE cable could do it.

That's my fear.  I was really hoping I'd get a response like "oh, x-vendor has a cable here, and it's pretty cheap." :)

I'm not certain I can drill holes in the connector.  Where the clock port pins hit is part of the clasp which holds the top to the IDC pins.

One of my A1200's had a full set of clockport pins on the motherboard. I think I just waggled them off with a set of needle nose pliers - They came off easily, very neat, and flush with the motherboard header...just the two required pins of course. Clockport cable then fitted perfectly.

With the plastic frame around the pins, I doubt you'd damage anything. Otherwise, someone handy with soldering equipment can remove them easily.

This is probably the same thing I'd do.  If I recall correctly, aren't those extra sets of pins completely useless?

Not really - you can hide them in food.

I pulled up Ian Stedman's archive on AmiNet.  Those extra pins are DRAM pins which all connect to the on-board 2MB and are for our purposes useless.  So, I suppose today I shall shear a couple of pins.

Also indicates to me that my motherboard is an early version.  1D.  I never bothered to look up what the versions are.

Excellent!
