https://sites.google.com/a/ricomputermuseum.org/home/Home/equipment/dec-pdp… We removed the 709 power supply and checked for physical damage. Everything looked OK. We reformed all of the capacitors in the power supply. All worked OK. We attached a resistive load to the power supply and measured the output voltages. All looked OK. The power supply fan was sticky so we sprayed some WD40 in the end bearing to free it up. It is noisy, but it works OK a few seconds after it is powered on. We reinstalled the power supply and connected the AC wires. We connected 110VAC to the power cord to the 841A power controller. We could control the power state with the power switch on the console. We connected the remaining red/white wires to the 709 power supply and found that all of the chassis fans work OK. Some are noisy though. The hour meter runs and we add a few tenths of an hour to the 40,163 hours already on the system. We connected the DC wires to the 709 power supply. We turned the power supply on for a few seconds at a time and measured the voltages on the chassis test points. The voltages looked OK and some lights on the console turned on. We tried the basic Examine/Deposit functions, but did not get the expected response. We can turn the PRGM STOP light on and off with the I/O RESET and START switches. With the REGISTER DISPLAY switch in the API position the REGISTER lights flicker. The rate of the flicker can be controlled with the REPEAT SPEED switch. Later this week we will do some basic debugging to see if any of the processor is working as expected. -- Michael Thompson

Anyone in Michigan need IBM 5120 (5110-3) parts?

by derschjo＠gmail.com

Hi all -- Earlier this summer I picked up an IBM 5120 (5110 model 3) in fairly rough condition in the Grand Rapids, Michigan area (where my parents live -- they kindly picked it up for me and stored it in their garage but now I need to make it disappear :). I bought it because I have a 5120 that needs a few parts (keyboard, monitor, ROS and CPU boards) and I'll be taking those back home with me. The rest of the machine is up for grabs -- anyone near the Grand Rapids area need any parts? I'll be in GR until Jan 1, so if you want 'em, speak up soon. Thanks, Josh

Symbolics 3620 Progress

by ggs＠shiresoft.com

I had some time last night so I spent several hours digging through documentation and sitting at the console to see if I couldn't make some progress. First of all, I figured out how to obtain the ethernet MAC address: show ethernet-address What I had to figure out that I had to be at the FEP (Front End Processor) prompt and not the LISP listener since that command is an FEP command. So now my home network is configured for when I get the Symbolics configured enough to enable TCP/IP (or as Symbolics names it IP-TCP). I also discovered (shouldn't be that big a surprise) that Genera doesn't really use configuration files. Everything is stored in the running LISP state. One thing that has to be remembered is that the entire LISP state needs to be saved when making configuration level changes (or installing new software). Just because it's on disk doesn't mean it can be used. I'm going to see if I can't get a bit further today. TTFN - Guy

Booting a Micro PDP 11/73

by robert.jarratt＠ntlworld.com

A little while ago I acquired a Micro PDP 11/73. It contains 2 DEQNA cards and an Emulex CU02. I am not sure what the CU02 is, but think it is some kind of disk controller, possibly SCSI, if someone knows what it is and can point me to a manual let me know. The automatic boot is setup to boot from the DEQNA cards, however I have no idea how to set up a boot node and I am not sure what OSs the 11/73 supports. I would be happy to run RSX-11M or RSTS, I have a SIMH emulation running RSX-11M, so perhaps that can be set up as a boot node? I also have a VMS boot node, but I have no idea if I can get that to boot a PDP11. If I have to I could probably make a TK50 or TK70 tape with boot media, and I probably have the means to get an RQDX3 with a disk installed, unless I can use the CU02? In the first instance I would like to avoid this route though because I just want to verify that the machine basically works. Any suggestions? Thanks Rob

Shugart 801

by rampaginggreenhulk＠yahoo.com

I'm looking at this: http://www.ebay.com/itm/Shugart-model-801-8-Floppy-Drive-/230897115754?pt=U… and it seems to be very similar to the drives in my Intel MDS box (blue if that matters, and that's all I have of an MDS system). The listing calls it a Shugart 801. I seem to recall Fred stating that a S* 800 was a *good* drive to utilize w/some peecee disk controllers.? Is an 801 also *good*? I e-mailed the seller intending to grill some info out of him.

Tektronix 4052

by cc＠informatik.uni-stuttgart.de

Hi, we've got a Tektronix 4052 with 4611 printer a couple of weeks ago. The system is almost working fine, it has an issue with the hard copy function (i.e. no signal). I'd like to understand the machine and its "Super-6800" processor and therefore I'm looking for a copy of the service manual (BTW it's a 4052 and not a 4052A; the firmware level is 4) for both the 4052 and the 4611. Christian PS: I've put the ROM images from our machine on our FTP server: ftp.informatik.uni-stuttgart.de/pub/cm/tektronix/tek4052 The images from the ROM patch ICs, PALs and microcode ROMs will follow soon.

VAX

by BHuntsman＠mail2.cu-portland.edu

Since some VAX stuff came up on the list recently... Anyone know much about the VAXbrick 4000-50? Not a lot of info on it floating around... Also, anyone here know how much a VAX 4000-200 in BA215 weighs, and/or have one that they'd be willing to sell? Haven't seen any come up lately... what's the going rate? I always thought that was the best-looking of the pedestal enclosures. Thanks! -Ben

Symbolics 3620

Just to let everyone know that my Symbolics 3620 just arrived. It was delivered by FedEx in two large boxes totaling 160 lbs. I've unpacked it and powered it up just enough to verify that everything seems to be working. I'll post pictures and more information about it as soon as I get a chance to put it in a more permanent place (right now it's in the living room?wife won't let it stay there long) and I have a chance to "play" some with it.

I don't think that the KS10 will boot from an RP07. The KS10 will boot ITS from an RM80. I am not sure how well supported it is with TOPS-10 or TOPS-20. I would recommend the RP06 for a disk and a TU45 or TU77 for a tape. -- Michael Thompson
