I've found that the TU58 emulator discussed above will not run under Windows NT - it will not even extract! It does extract under Win 98, and runs (and extracts) well under DOS 6.22 I'll let you know if it works with my 11/23+ tomorrow, I should at least be able to make an image of (part of) my XXDP disk, though it depends whether I can configure SLU2 (on the CPU board) as the TU58 port. Am I correct in thinking that XXDP(V2.3) will assign a DD drive number for the TU58? (it calls my RL02 DL0). Jim. Please see our website the " Vintage Communication Pages" at WWW.G1JBG.CO.UK

Aux Power

by hachti＠hachti.de

Hi people, on my PDP11/23+ there is that key called "AUX POWER". But it doesn't do anything on my machine. The only power switch is at the back of my machine. And there is an unused connector at the back of the front panel. From that little panel goes a cable to the back of the PDP which ends in an unused connector, too. Somebody said something about a power bus?? I have not found the posting... Does a fancy power switching (everything in the rack at once) system exist? If yes, what do I need to get my rack complete? Best regards, Philipp :-)

Still Available for free

by cb＠mythtech.net

>Where are these? I'm in the market for a PC, PC/XT or PC/AT. Also >looking for a Compaq Portable III. Northern NJ (Ridgewood, 07450). I don't have a Compaq Portable III. I have what I believe is the ORIGINAL Compaq. Their luggable suitcase sized thing with dual floppies, and 5 in screen in a nice luggable case. I'd suspect I can probably sell it on ebay, but at this point, I've been thinking of doing that for a very long time, haven't gotten around to it, and now just want to get rid of them. There is at least one, maybe two (I think it is two Corona's, one complete, one missing the keyboard case/top cover, and one complete compaq). -chris <http://www.mythtech.net>

<http://www.classiccmp.org/hp/PDP-8%20cards/flip%20cable.jpg> It has a male connector on one end and a female on the other. The cards are marked FLIP-CHIP. Joe

ARE DEC "Cab-kits" worth anything?

by rigdonj＠cfl.rr.com

I picked up a sack full of these <http://www.classiccmp.org/hp/PDP-8%20cards/cab-kit.jpg> last week. Thom says that they're valuable but I was just going to rob so parts out of them. If they're worth much I'll use them for trading material or E-bay them. if they're not worth much, I'll just pull the parts that I want and pitch the rest. Joe

Heathkit HDOS source listings

by dwight.elvey＠amd.com

Hi Rich There is a separate mail group called sebhc that is specifically early Heathkit. It has a ftp that we have collected various images of HDOS and HUG disk as well as some documentation. I'm sure it would be great to have it sent there. There has been some recent discussion with some of the other authors of HDOS that also participate on that group that none of them have saved any of the source code. I am forwarding your message to that group as well.

Can anyone id these DEC PDP-8(?) cards? Also pictures on my PDP-8 cards

by rigdonj＠cfl.rr.com

Here is a collection of cards that I found in various DEC PDP-8 chassis last week. Can anyone id them? <http://www.classiccmp.org/hp/PDP-8%20cards/CESI%20LPC8.jpg> Marked CESI and LPC8. I'm guessing that it's a line printer interface for the PDP-8. It has a 40 pin ribbon cable header on it. <http://www.classiccmp.org/hp/PDP-8%20cards/Emulex%20TU1110406.jpg> Made by Emulex and marked TU1110406 2A. Looks like some kind of tape controller to me. It has two 40 pin ribbon cable headers on it. The LH one is marked To TC01 or TC11 and the RH one is marked To Tape Deck. The rotary knobs on the lower RH edge select speeds of OFF, 125 ipc, 75 ips, 45 ips or 37.5/25 ips. This one <http://www.classiccmp.org/hp/PDP-8%20cards/PN%203021%206002.jpg> has a symbol that looks like the National Semiconductor symbol but it has three lightning bolts instead of two. It also has the number 3021 6002 on it. The cables have been cut off so I have no idea what was on the other end of them. The only marking on this one <http://www.classiccmp.org/hp/PDP-8%20cards/PN%20140014.jpg> is the number 140014. This card <http://www.classiccmp.org/hp/PDP-8%20cards/XEBEC%2001-100968.jpg> was made by XEBEC and has the number 01-100968 on it. It has two 50 pin ribbon cable headers on it. This card <http://www.classiccmp.org/hp/PDP-8%20cards/OTR%20120.jpg> was made by Computer Idenitics Corp and says that it's an OTR-120 interface. (Optical Tape Reader?) The rest of the photo in the same directory are DEC cards for my PDP-8 with the exception of the Plessey RK-05 disk drive controller set (3 cards). BTW Thom is cleaning up and found 198 various disk cartridges yesterday. Many of them contain software, diagnostics and/or Operating Systems. If anyone needs any cartridges he's looking to sell all of them so give him a call. And yes, he does have some alignment packs, CE packs, etc but he'll want real money for them! Joe
