Re: Port Extender for HP 41 Message #2 Posted by Raymond Del Tondo on 3 Feb 2003, 10:08 a.m., in response to message #1 by Klaus (ger) When I was younger, these port extenders were relatively common amongst die-hard HP-41 users. A few people from the CCD club had either the one from CT or a similar type, I don't recall the brand. But since my I had (and still have) the MBK ProfiSetII RAM box, there was no need for me to get that CT device back then. If I had known how rare they're now, I'd bought one, of course;-) Regards, Raymond Before you ask: The ProfiSet RAMBox existed long time *before* the W&W RAMBox. Actually, the W&W Box OS was developed with an MBK ProfiSet.

I have 2 of these and they are a valuable item in terms of what they can do. The Port-X-Tender also has dip switches so you can turn ports on and off as needed. Chris

Re: Port Extender for HP 41 & other goodies Message #4 Posted by Raymond Del Tondo on 4 Feb 2003, 7:04 a.m., in response to message #3 by Chris(FLA) Hi Chris, many thanks for the enlightment. Regards, Raymond BTW: Do you recall the plug-in miniature light for the HP-41? I was offered such a thing by my favourite HP dealer back in the early eighties. It consists of a printer plug with a switch, a flexible arm, and of course the light at the end of the arm.

Hi Raymond, No idea what that item was. This sounds like a reading light type thing maybe so you can use the machine in low light? Sorry can't help you more. Chris

Re: Port Extender for HP 41 & other goodies Message #6 Posted by Jake Schwartz on 7 Feb 2003, 11:09 a.m., in response to message #5 by Chris(FLA) The Port-X-Light was also made by AME in a fit or "madness" <grin>... it worked, but did suck battery power from the HP41 itself. Same time frame as the Port-X-Tender - right around 1982. They sold both like hotcakes at the Philly PPC Calculator Conference that year. Jake Schwartz
