I might be interested. Have you thought about making extensions for the smaller connector used to distribute GPIB in the 5000 series?

Should be here in a couple of weeks.  It uses two 39/40 pin ribbon cables (all the power pins use two wires)... e.g.  IDE/PATA disk drive cables.

Is there any interest in purchasing a kit of all parts to build an extender cable.   With a moderate amount of interest the price  looks like it would be around $20 per kit plus shipping (probably around $6 for shipping in the US for as many that can be stuffed in a small priority mail flat rate box... most serious TM500 users will want 2 cables for the wide modules).  Kit cables would be 18-19" long.   TM500 extender cables have been selling on Ebay for $150-$350!
