Connecting LK250 to VAXmate

Sorry, yes, I meant RJ like for a telephone. I believe the SDL end may be like an IBM but I don?t know, it is one of these: https://en.wikipedia.org/wiki/Shielded_data_link_connector Regards Rob From: Jason T <silent700 at gmail.com> Sent: 15 June 2019 14:46 To: General Discussion: On-Topic and Off-Topic Posts <cctalk at classiccmp.org>; robert.jarratt at ntlworld.com; rob at jarratt.me.uk Subject: Re: Connecting LK250 to VAXmate On Sat, Jun 15, 2019, 03:28 Rob Jarratt via cctalk <cctalk at classiccmp.org <mailto:cctalk at classiccmp.org> > wrote: I recently acquired a VAXmate with an LK250 keyboard. The problem is the keyboard came without the cable. It uses an 8-pin SDL connector and the usual tiny MMJ-like connector at the keyboard end. I don't know the pinout and I don't have the necessary crimping tools, is there any source for such a cable? Is it actually MMJ, with the offset pin, like a DEC serial cable? Or is it just an RJ connector like a telephone handset? And is the SDL end the same type as on an IBM model M keyboard? I have a VAXmate buried in storage. With enough prodding I could dig it out and try to determine the pinout of the cable.
