Subject: DEC part number for RL02 unit number plugs ?

From: Bob Armstrong <[email-masked]>

Can someone tell me the part number for the unit select plugs on
the front of a RL02 ?  I have an RL02 that would work if I just had
the right numbered plug for it!  I need a #2 if it makes a difference.

  DEC part number assistance has not been able to figure this out -
the best they could do was to come up with the part number for the
entire front panel!

Thanks,

 it's 12-12691-00   (for unit zero... break pins for other numbers)

 ??? can't DEC use IPB fiche anymore??

hmmm... i just looked it up in a 1993 catalog... the "-00" denotes
 unit zero, -01 unit one, etc. but the prices are interesting:
 zero and one are $2 each.  two and three are $4 each.  five and six are $1.

The pricing weirdness is probably due to demand or rarity or something.
Note that RL controllers support only drives 0-3, the numbers >=4 are for
RK06/RK07 drives, which use the same plugs, but are less common.

Not on an RL-drive. There are 2 pins that encode what number it is, and the
shape of the top and bottom edges of these pins is what matters. There is no
easy way of converting one plug into another.

Mind you, it's possible to cut/jumper the switch board in the RL-drive in an
emergency

RL's are only 0-3 - there are only 2 drive select lines in the hardware. The
same plugs fit RK06's/07's, and also some CDC drives, like the 9448

RK06's/7's have numbers 0-7

A nail-file, he said darkly, works wonders...
