Pretty clever, to get that complex a pattern out of so few instructions. Although the self-modifying code is, err.... (If anyone wants the source or .LDA, let me know, I can post/upload it.) On the Unix machine we had at MIT, I 'stole' a light pattern I'd seen somewhere else (not the code, just the visuals). The code is considerably longer, but I didn't try to bit-push it, just wrote something very straightforward to produce that pattern. Noel

RT-11 idle light pattern

by fritzm＠fritzm.org

I have been able to sysgen an RT-11 XM monitor with the idle loop light pattern enabled, and install and boot it on my PDP-11/45. Here?s a video of the idle lights: https://www.youtube.com/watch?v=ycADKwgnLpE I built the latest simh and tu58em from source on my MacBook, then was able to do the sysgen under simh, copy the resulting binaries onto a TU58 image using simh?s TDC device, then use tu58em to copy the binaries over onto my working RT-11 4.00 distribution RK05 pack. It was pretty fun to get all this working ? I had never seen RT-11's console light pattern before! ?FritzM.

OT: Argh--my old faithful HP16C is failing!

I've read a bit on the HPMuseum forums that indicate that early displays aren't interchangeable with later ones--the later ones apparently use a finer-pitch connector. My own HP 16C has a serial number beginning with 2228A..., which I believe puts its date of manufacture in 1982, so my fingers are crossed to see if the "old" HP12C that I picked up on eBay is even close in terms of display connections. --Chuck

tumble tiff to pdf converter

by jwsmail＠jwsss.com

Has anyone tried to build tumble on Ubuntu 16?? I've used the libtiff, libpbm and the like that are included in the current system as installed, and there are problems now with the tumble_pbm.c code parameters (line 237 specifically). I had built up and saved a build with my own downloaded and built libtiff and libpbm, but those packages won't build anymore either. Hoping not to rathole Al maybe Eric?? someone else who is using it to convert tiff to pdfs.? I've scanned some stuff and would prefer to use the full bitsavers toolchain, as well as have notes on how to build going forward. I'll flail on it more if noone is interested, but spent enough times tonight trying to build it before asking. thanks Jim

The LSI-11 I had at last spring's VCFs did that with a little home-brew 6809 board I was using for TU58 emulation. I wasn't going into a DLV11 per se, but into an MXV11. I'd have to go back and look at the details to see how fast it was actually running. Somewhere in the back of my mind, I had to back off a little bit on what the hardware could do because something on the software side couldn't take it that fast. BLS

Help Identifying Components

by shadoooo＠gmail.com

Hello, while I can confirm that the bigger black with two pins is a diode, I'm not sure what kind of diode it is, as it could be bipolar, Schottky or Zener. About the smaller black components with three pins, they could be transistor or diodes (single or double, with common cathode, common anode or series). I will try to find a correspondence for the markings, but symbols are someone strange, so a clear macro picture would be better... Andrea

Help Identifying Components

by robert.jarratt＠ntlworld.com

I am continuing work to reverse engineer the schematic for my H7826 PSU. I have removed one of the daughter cards in order to draw its schematic, but I can't identify some of the surface mount components on it. I have posted a picture of it here: https://rjarratt.files.wordpress.com/2017/12/50-19530.jpg The ones I can't identify are: 1. The component with two wide pins that looks like an IC approximately in the middle of the board. It is marked M106 (or it might be AA106) and 91813 underneath. I think it may be a resistor, but I am not sure. 2. Just to the right of this is another much thinner two-pin component which is black on top with a kind of white notch. I have no idea at all what this is. 3. The three 3-pin black components to the left of the first component. Two of them are marked "2T L" (or is that "ZT L"?), one appears to be marked "2X I" (letter "ih", not letter "el"). I guess they are transistors, but they may not be of course, and I don't know their pinout. Any help with identifying what these are would be very helpful. Thanks Rob

Restoring a VT50 (VT52 actually) .

by mattislind＠gmail.com

I have started to work on a getting VT50 terminal back to life. When digging into it I recognze quite immediately that someone had done a brain transplant on it. It has VT52 boards in it! Was this a usual procedure? The VT50 to VT52 shift looks like a failure of DEC at the time. So close in time. But different board sets inside. They could have designed a board with RAM upgrade possibility and just a new microprogram? Looks strange to me. When the VT52 got on the market I guess it was hard to sell any VT50s or was there a substantial price difference? Anyhow, the VT52 boards are dead. They generate the proper sync signals but there are no keyclick generated when pressing keys on the keyboard. Which is quite normal since the sync is generated by a chain of counters while the keyboard is controlled by the microprogram. The terminal uses 4 pieces of 256 by 4 bipolar PROMs for a total of 512 bytes of microprogram. Has anyone dumped the contents of these so I could verify them?

Miss categorized DEC box on ebay

by jnc＠mercury.lcs.mit.edu

> From: Bill Gunshannon > At best, it's a third part QBUS box. I assume that was 'third party'? No, that's a real DEC front panel. They could have put that on an off-brand chassis, but I would _guess_ not. (The outer housing I can see looks like the slide-in ones DEC used to hold the BA11-N/BA11-S, but I don't recall what the housing for the BA11-M's looked like.) For some reason the BA11-M's seem to have been going for more than the BA11-N's. Dunno why, maybe the original LSI-11's have some sort of appeal? Noel

DEC indicator panel mounting details

by jnc＠mercury.lcs.mit.edu

So, Dave and I are getting to the point where we're about to start mounting up our indicator panels, but we're not sure what some of the mechanical details (below) are. Could someone who has one please take a look and let us know (or, even better, send us photos)? It appears that the bezel and inlay mount to the rack with the same kind of 'ball on post' (BoP) mounting things used for blank panels. What we can't quite make out is how the Belenex light shield, and the circuit board with the bulbs on it, mount to the rack. I suspect it's totally independent from the mounting of the BoP mounting devices for the bezel/inlay, but.... The one mechanical drawing we have (RF11 engineering drawings, pg. 186) does have cross-sections, which confirm the board is mounted to the Benelex on stand-offs, and that the Benelex is somehow thrust up into the bezel, but exactly how the Benelex is mounted is not clear to me. The mention of a "Mtg Bkt Benelex" suggests that's mounted to the rack with brackets, but... Help!? Thanks (hopefully :-)! Noel

MicroVAX I Diagnostic floppies

by derschjo＠gmail.com

Hi all -- I'm attempting to resurrect a MicroVAX I (because it's there, that's why) and the CPU appears to have developed a fault. Microverify passes at powerup, but I can't get VMS to boot (it dies with a SYSBOOT-F-Unexpected Machine Check almost immediately). Also tried Ultrix and it dies shortly after enumerating disks. I know the memory and disk controllers are fine, and there's nothing else in the system at the moment, so unless anyone has any bright ideas, I think I'm going to need to debug the CPU. I'm trying to track down the diagnostics for this machine, no luck so far. Anyone have a copy sitting around somewhere? I believe there were two RX50 floppies for this purpose, DEC part numbers BL-T856A-DE and BL-T857A-DE. Thanks as always, Josh

IBM 3480 DEC TKZ60 inquiry

by cclist＠sydex.com

Hi Folks, We've got a Canadian customer with what appears to be an IBM 3480 cartridge that he'd like to get the data from. We don't get nearly enough request for these IBM carts to make owning a unit a viable proposition. I understand that the 3480 format was supported by a wide range of vendors, including DEC with the TKZ60/TKZ61. Anyone having one of these drive want to make some easy money? FWIW, the customer thinks that it's a lot older than it really is--he thinks this dates to the 1970s and the S/360, so some gentle advice may also be required. If you're interested, drop me a private email and I'll hook you up. Cheers, Chuck

Odd Connections to Rectifier?

BT139-600G Triac Equivalent

by robert.jarratt＠ntlworld.com

I have a suspicion that this component may be faulty on the input side of my H7826 PSU. A little tester I have does not recognise it, it is possible that the currents it uses are too low for this particular triac, but I am not sure. There are new ones on ebay, but I am not sure if I can trust ebay sellers to have genuine parts. So I would like to identify a suitable replacement. I have found a few suggestions for replacements, but looking at the datasheets many seem to have a lower peak gate power then the BT139. I am not sure what the critical parameters are, so I don't know how to choose a replacement. Can anyone suggest a good replacement for this part? Thanks Rob

RL02 weirdness

by aaron＠aaronsplace.co.uk

Now that I have my RX02 drive working I have started to take a look at the RL02 drives again. I hooked a scope up to the sector transducer and sector timing test points, and they look nicely aligned. So I moved on. Then I hooked up the scope to the TP1, TP2 and the sector timing TP and compared it to the output in the RL02 tech manual. S1 was fine but S2 was offset in the wrong direction (probably need to see page 3-8 in the manual to understand). I had a look at where the heads are connected to at up was connected to down and down was connected to up. Without understanding the consequences I switched these and loaded a pack. Unfortunately I heard a horrible sound and I now have a thin black ring on the bottom side of my platter, which I am very upset about. :( I unloaded very quickly but I think the damage is done. Why would the heads be installed this way? and why did it destroy my platter when they are connected "correctly"? Does anyone understand what might have happened? Thanks, and sorry for destroying a pack :( Aaron.

RX02 Difficulties

by aaron＠aaronsplace.co.uk

Hi everyone, I originally posted this on VCFed (which was new to me) but the moderation queue has had me waiting for about 3 days, so I thought I'd ask here as well, the usual of gurus. :) I was recently sent an RXV21 controller so I could test out my RX02 drive. When I power up the PDP-11 or reset the machine I get the nice clunking sound which I have been told is normal. I expect I wouldn't hear this if the ribbon cable was in the wrong way. To test, I tried to use VTserver to dump the contents of a disk, but it immediately threw an error. I soon realised there are two DIP switches on the logic board of the RX02 drive which had to be adjusted to work with the RXV21. So, I had some progress. Output of VTserver almost looked promising but then it hangs, as below: ]] Tape record n from device xx is written as xx(0,0,n) ]] Disk drive xx is written as xx(0,0,0) ]] ]] Enter name of input record/device: rx(0,0,0) ]] Enter name of output record/device: vt(0,0,1) ]] ]] Opened copy.out read-write ]] So, following some advice I booted via TU58em into XXDP and ran the diagnostics: ]] DR>STA ]] ]] CHANGE HW (L) ? N ]] ]] CHANGE SW (L) ? N ]] ]] CZRXFB0 SYS FTL ERR 00040 ON UNIT 00 TST 011 SUB 000 PC: 003476 ]] CSR BITS - LGC TST ]] AC LOW FATAL ERROR ]] REG ACTUAL=000000 ]] REG EXPECT=000000 ]] ]] POSSIBLE FAILING "FRU'S": ]] INTERFACE - M8029 ]] ]] UNIT#0 RXCSR=000000 RXESR=000000 CMD=000000 -> ]] ->NO PWR, CABLED BACKWARDS, STRAPPED RX01, PDP-8 ]] DROP UNIT#0 FROM TEST ]] ]] PASS ABRTD THS UNIT ]] CZRXFB0 SYS FTL ERR 00040 ON UNIT 01 TST 011 SUB 000 PC: 003476 ]] CSR BITS - LGC TST ]] AC LOW FATAL ERROR ]] REG ACTUAL=000000 ]] REG EXPECT=000000 ]] ]] POSSIBLE FAILING "FRU'S": ]] INTERFACE - M8029 ]] ]] UNIT#1 RXCSR=000000 RXESR=000000 CMD=000000 -> ]] ->NO PWR, CABLED BACKWARDS, STRAPPED RX01, PDP-8 ]] DROP UNIT#1 FROM TEST ]] ]] PASS ABRTD THS UNIT ]] CZRXFB0 EOP 1 ]] 2 TOTAL ERRS So, the possible errors according to XXDP: - Bad power - I get 25v, 5v and -5v. The motors are spinning, not convinced it is this? - Cable backwards - I don't think I'd be hearing that clunk. - Strapped RX01 - I don't know what this means - PDP8 - eh? If anyone has any suggestions it would be great to hear them. Thanks, Aaron.

Just to clarify, by "slot", you don't mean 'backplane slot', you mean 'socket (on the card)', right? Also, note that the console/diagnostic ROM is a different size (bit-wise; I'm not sure about the physical package) from the bootstrap ROMs. > 6) possibly the only switch to worry about now is the power on auto > jump to console switch. I'd leave that, too, until we get the software console to run when started manually - at the moment, the ROM's not working, so that switch is irrelevant. Noel

ISC Intecolor 8300 terminal

by arcadeshopper＠gmail.com

I recently picked this up from shopgoodwill and it has an older power plug. It is NOT a standard plug as shown in the picture below that is too tall and pins are smaller etc.. Anyone know the name of this 'standard' so I can find a cable? Or possibly have one around I can get from you?

> From: John Welch > CLR > 765000 > LAD > EXAM > 'Bus Err' light comes on. Oooh, that's very interesting, and illuminative. The ROM isn't working (so there's no way for the software console to work - its code is in that ROM). So look at Section 1.5 of the Technical Manual http://bitsavers.org/pdf/dec/unibus/M9312_TechRef.pdf and make sure all the jumpers on the M9312 are as required. In particular, jumper W-8 should be _out_. If it's not, that would explain why the ROM at 765000 isn't resonding. If it's in, that M9312 board probably has a problem. Also, while we're at it, it's probably worth making sure the CPU will run. Do this: CLR LAD 777 (This is a 'branch .' instruction) DEP EXAM (Should display '777') CLR (I think you can dispense with these LAD two, but just to be safe...) CTRL-START 'Run' light should come on CTRL-HALT 'Run' light should go out, should display '0' (or maybe '2', I forget) > Do you know which color wire (red, clear, black) goes to which festoon > connector (TP1, TP2, TP3, TP4)? I would leave them all disconnected for the moment; you don't need them. One is the 'boot' switch on the console, and its ground. The other is the 'boot on power on enable' (a duplicate of S1-2), and its ground. Since we're trying to manually start the ROM console from the front console, they aren't needed for that. I don't recall offhand which one connects to which - I will have to check. > Don't want to blow anything up. Not sure it will harm anything if you connect things wrongly, but that's not tested. Noel
