You can make your own, or buy something cheap to build a good one out of. The HarborFreight one is barely usable for this unless/until you add a thermostat, a fan, a timer, an extension cord, . . . Were you looking for one that already has the desired enhancements? I used one sorta like it 35 years ago (before HarborFreight was selling one)

do not get this EVIL no fan no thermostat... found BOOOO! NOT A GOOD ONE ( for tapes) manual for it http://manuals.harborfreight.com/manuals/66000-66999/66906.pdf I have one wife found at garage sale ... it is not good for tape work... I rather suggest $64 http://www.amazon.com/Nesco-American-FD-61-Snackmaster-Dehydrator/dp/B000CE… I thinkI got mine at Walmart - but remember use the thermostat to on off the thing but for actual temp use a process thermometer .

That is how I have modified mine to accept 1" C format Videotape reels. Oh, maybe I misunderstood, then. I thought the center support was some sort of fixed air duct, and that anything too large to fit between the center and edge would need a center hole large enough to fit over the center support. -- Mark J.

Applikon Workstation?

by holm＠freibergnet.de

In the nineties I've workes as electronican and system administrator at the institue of geophyics at our local University of Mining and Technology here in Freiberg Germany. Some day I've got a call from Motorola in Munich, they wanted to get rid of some old computers and asked if we had some use for them, I've sayed yes. As far as I know we got 3 Computers, one was an 68000 Unix system from philips, some kind of Microcomputer development system for 8080 or 8085, I've got the system running but since there wasn't much software on the disk we had not much use for this thing. The disk was alsready dying and lived not that long. The next thing was a desktop VME System from Motorola, IMHO equipped with an 68010, some MMUs, an color Monitor ad Harddisk and Floppy.. it run some kind of VDOS (or so) .. or VME-DOS or soemthing.., I remember that we had some documentiation for it and I've reinstalled that VDOS.. but not much use for that thing also. The 3rd Computer was the most interestng one. That thing was labeled "Applikon Workstation" (as far as I remember, may be Applicon..). That was some kind of a microvax made by Schlumberger. It had an CPU that sat in a QBUS Backplane and a QBUS to UNIBUS Bridge. The CPU was only a double sized board (!), an Emulex UC07 conected the disk to the machine and so far as I remember there was some kind of graphics board on the unibus side. I've repaired the CPU Board by changing the RSA232 Drivers for the console and the beast came to live. I've fiddeled around with the TK50 Tapes containing VMS4.6 (if my memory not fails) but could'nt get warm with VMS... Installed NetBSD and failed. NetBSD was'nt booting from the SCSI Drives with the Emulex, someone sent me an UDA50 and I was able to install and boot NetBSD, but had to key in the loader at the chevron every time I had to boot.. I've sent the Emulex to Ragge for diagnostics and never got it back. The Machine ran for years as ftp server at the institute until I've pulled the plug. Have never seen a picture from that graphics board. I've leaved the University in 1989, the machine sat on the garret of the building to this time, I'm pretty sure it's long gone... Now I'm fiddeling with VAXen again and that old thing came to mind, looked with google but could'nt find a machine like this, not even a Microvax with a only doubles sized CPU Board like an KDF-11. The question now is...is someone knowing of a beast like this? Regards, Holm -- Technik Service u.

Xerox 820-II's available

by shaunhalstead＠gmail.com

Note: I've moved my ccmp stuff to my personal email account. I was formerly with Microfilm Services, Inc, which is now shuttered. I still have a pair of Xerox 820-II computers available, in Wichita, Ks. Two computers, with keyboards, and a single dual 8" floppy unit. I also have a few books and manuals for them, in original Xerox binders. Price: Make offer. PLEASE. After Labor Day weekend, they will probably be destroyed by the building owner. Shipping is in 4 large boxes from Wichita, Ks, and will not exactly be cheap. You can figure $100 minimum for shipping. Alternatively, I'm heading north along I-35 from Wichita, Ks to north Iowa Thursday 9/3 and Friday 9/4, if you wish to arrange a meeting along that route. (It must be at a location directly long I-35, such as a truck stop or other major, easily accessible location.) --Shaun

IBM 1620 / IBM 1401.

by geremin＠iprimus.com.au

Here in Australia, the Australian Computer Museum Society has an IBM 1401 - just the big CPU unit. We know of an IBM 1620 CPU unit in Computer Sciences at the University of NSW. I worked on a 1620 in the 1960s - and thought that it was 'magic'. Sadly, we don't have enough sponsors to put either on public display.

wanted - MXV11-B (M7195-XX)

by Mark＠Misty.com

Hi, Does anyone happen to have a spare MXV11-B (M7195-XX) they would be willing to sell or trade? I'd like to build a small BSD2.11 system from this M8192 from the cheap board guy on e-bay and need something with a bootstrap ROM. Mark -- Mark G. Thomas (Mark at Misty.com), KC3DRE

RP06 drives are typically connected to 3-phase power, but only use two of the three phases. I have and RP06 running at home on 110/220VAC 2-phase. -- Michael Thompson

Announcing TCP/IP for RSX-11M-PLUS

by bqt＠softjar.se

I'm happy to announce a new release of TCP/IP for RSX-11M-PLUS. Since I'm broadening the scope of the announcement slightly, a more complete list of features is included, and not just what changed since last. For anyone who is currently running TCP/IP for RSX, I strongly encourage you to update to this latest version. Several improvements have gone in in the last couple of weeks. Most important change is that there now is telnet support, both client and server side. The TCP/IP for RSX that I've written is sometimes referred to as BQTCP/IP, just to make clear that it is a different product than Process Software's TCPWARE, or JSA's TCP/IP. BQTCP/IP is a rather feature rich TCP/IP implementation, which also comes with libraries for various high level languages. The API is not compatible, even at the source level, with Unix, but on the other hand, if people write some code, they will see that it is a very easy API to work with. The reasons for the incompatibilities are several, including both resource concerns and differences between how RSX works and Unix like operating systems. BQTCP/IP has tried to comply with all relevant RFCs, but I'm sure there are corners where it does not do things right. It also does not demand much resources. It do require RSX-11M-PLUS with split I/D space, and it has only been tested properly on RSX-11M-PLUS V4.6. It should work on any version 4 release of RSX-11M-PLUS, but there might be a couple of tweaks or fixes needed. BQTCP/IP is distributed in binary form, so very little compilation is required to get it up and running. However, pretty much all utilities do come with sources. The actual TCP/IP stack sources are not included. I do not have a good setup for distributing them in a sane way, and it has had a low priority on my list of things to do. But I do not mind distributing the sources as a general principle. All that said, BQTCP/IP current supports the following protocols: o Ethernet and loopback interfaces. o ARP. BQTCP/IP can use Ethernet in co-existance with DECnet, or standalone using the provided Unibus ethernet device driver. o IP. The largest IP packets supported are approximately 8KB. o ICMP. o UDP. The largest UDP packets supported are approximately 8KB. o TCP. The window is approximately 8KB in size, and TCP do manage out of order packets in an efficient way. BQTCP/IP supports the following applications: o DHCP. DHCP can be used to configure interface addresses, network masks, default gateways, DNS servers and NTP servers dynamically. o NTP. NTP can be used to set the local time. o TELNET. The TELNET server hooks in to the standard TT: terminal driver, and the number of terminals to create is configurable. The TELNET client can be used to connect to other systems. o FTP. The FTP server can serve all kind of files to other RSX systems, and can serve text and binary files to any system. The FTP client can retrieve RSX format files from RSX servers, and text, binary and block format files from any system. o TFTP. The TFTP server and client can be used for simpler file transfer operations. o RWHOD. RWHOD is a program that reports current users and uptime from RSX, for other systems to collect. o IRC. IRC is a program to communicate with other users around the world. o IRCBOT. IRCBOT is a small example robot program connecting to IRC and performing a service for IRC users. o PCL. PCL is a protocol for printing, used by HP (and other) printers over a network. The PCL implementation in BQTCP/IP appears as a print symbiont, which you can create a printer queue for. o WWW. WWW (or World Wide Web) is a service that can present hypertext information to clients. The WWW server in BQTCP/IP also supports CGI, which makes it possible to create dynamic content. o DNS. BQTCP/IP have DNS implemented as an ACP, that anyone can query to get translations between IP addresses and domain names. It also supports different users using different name servers, or private translations. o SINK. A standard TCP service. o ECHO. A standard TCP service. o DAYTIME. A standard TCP service. o QUOTD. A standard TCP service. o IDENTD. A standard TCP service. BQTCP/IP also have automatic IP spoof detection and prevention. Additional tools are IFCONFIG, PING, TRACEROUTE, NETSTAT as well as two new pages for RMD. High level language libraries exists for BASIC+2, PDP-11 C and FORTRAN-77. I'm sure I have forgotten a thing or three, but that's a fairly comprehensive list. The documentation is a weak point, but there is hopefully enough documentation to get people running, and I am happy to answer any questions, or give support if needed. BQTCP/IP is already running on the internet, and have been for a while. People who are curious to check it out can ether look at http://madame.update.uu.se/, or telnet to telnet://madame.update.uu.se and login as user GUEST with password GUEST, or use ftp against ftp://madame.update.uu.se. Anonymous ftp account exist. As usual, the distribution is available from: ftp://madame.update.uu.se/bqtcp.dsk ftp://madame.update.uu.se/bqtcp.tap ftp://ftp.update.uu.se/pub/pdp11/rsx/tcpip/tcpip.dsk The .tap file is an RSX virtual tape. It is only possible to download and use if you are using FTP from anther RSX system and fetch the file. The .dsk files are virtual RL02 images that are useful both from within RSX as well as through emulators. The documentation is also available through ftp on Madame, or also at http://madame.update.uu.se/tcpipdoc Johnny
