It appears to do nothing but create more problems if turned up higher than that. It was worth a try. --Chuck

Cloning A Hard Disk Over The Network Using Ultrix

by robert.jarratt＠ntlworld.com

I have a couple of hard disks I want to make dd copies of. I have Ultrix running on my DECstation 5000/240 with the disk I want to clone attached to it. The trouble is that I don't have enough disk space on the machine to clone the disk and then grab the image using FTP. I have been trying to find a way to pipe the dd output over the network to a SIMH Ultrix machine that has plenty of disk space. I tried piping dd into rcp, but rcp doesn't seem to take input from standard input. I have looked at cpio, but that too appears not to accept input from standard input. Unix is not my strong point. Are there any other ways I could pipe the dd output across the network to a machine that has enough disk space? Thanks Rob

And how does one know that a font supports UTF-8?

No you are not. I use (al)pine on my OpenVMS system here as well as my main Linux host. I have mail going back to 2004 here and since 1996 at another public access Unix host I use. It's great when I'm out of town and can ssh in from my phone and check the mail. :) Pine does most everything I need without having to worry about malware, phishing, etc ... the beauty of text. Fred

CDP1801

by vintagecomputer＠bettercomputing.net

I'm going to put it on my list of projects to create a CPU card for my Microtutor that uses the 1802 instead I think.? I can get some blue PCB stock.? As far as I understand the 1802 is fully backward compatible. Maybe the 1801s will show up on day.? I've found all kinds of chips I was told were impossible to locate. Sent from my Samsung device -------- Original message -------- From: Steven Feinsmith <steven.feinsmith at gmail.com> Date: 2017-10-20 7:32 PM (GMT-08:00) To: Brad H <vintagecomputer at bettercomputing.net>, "General Discussion: On-Topic and Off-Topic Posts" <cctalk at classiccmp.org> Subject: Re: CDP1801 RCA 1801 disappeared from face of Earth forever... You would be better off to purchase at: http://www.sunrise-ev.com/membershipcard.htm to use 1802. The 1802 was very successful microprocessor that replaced 1801 because it required to have a pair of chips to work together. I believe I saw 1801 was more than 30 years ago. Good luck!

I can recreate the card but I expect locating the 1801 chips will be difficult.? I am just posting this in various forums in case anyone has any leads on where I might find either the complete card or the required chips to make a replacement.? I'm wondering what, if any devices were built with the 1801 that I might be able to scrounge from. Thanks again, B

Giving away my collection to someone just starting out in the hobby

by drlegendre＠gmail.com

Steve, I don't think I qualify to receive the whole shebang, nor would I have room, but I will gladly take any box(es) un-tested / for parts / etc. C-64 hardware that you would care to offer. I endeavor to repair CBM machines, primarily C-64s and peripherals, and I am basically out of parts. I have almost a dozen machines stacked up that can't run for want of various parts... I'm in St. Paul, MN, and unable to work due to total disability (stage 5 kidney disease. among other things).

I'll just stay away from DU1:.? I forgot about the reboot required for these changes to take effect.
