What the heck is the deal with this eBay item

by AppleCorey＠optonline.net

https://www.ebay.com/itm/272433760795 This Helios II has been "sold" multiple times for varying amounts and then suddenly hours later appears for sale again. I'm done bidding on this each time it appears, because if I won, who knows what I'd receive or if the seller would cancel the auction. corey cohen u??o? ???o?

General TC11 DECtape diagnostic/formatter questions

by jnc＠mercury.lcs.mit.edu

> From: Christian Corti > Seems the original must have been the XXDP TC11 DECtape formatter > program by Robert J. Collins. I have no clue where I found the RT11 > version of this So that made me wonder if the V6 Unix version of tcf.s really was related to DTF.MAC. I checked out the two of them, and it seems they are likely un-related; very different structure, etc. BTW, I noticed a couple of places in DTF.MAC where error checking code was commented out, e.g.: ;EHLT4: XX ;HALT WITH BLK#IN LIGHTS, CONTINUE ; MOV #257.,R0 ;TO FIND DATA WORD POSITION ; ADD TOG1,R0 ;DETERMINE WHICH WORD IS WRONG ;EHLT5: XX ;HALT WITH #OF WORD IN LIGHTS. 0=REV. CHKSUM ; MOV @TCDT,R0 ;CONTINUE TO FETCH BAD WORD ;EHLT6: XX ;HALT WITH BAD DATA IN LIGHTS. CONTINUE Maybe it would be useful to un-comment them? > On Nov 9, 2016, at 5:57 PM, Josh Dersch wrote: > I believe S/B is the expected data Yes, probably stands for 'should be'. Noel

I had a look at tcf.s, and it depends on having been loaded by the V6 disk bootstrap - it uses the console driver in the bootstrap (the bootstrap leaves a pointer to it in R5). So it might be easier to use that DTF.MAC, which seems like it's mostly the same program, and which you apparently already have working? If you'd still like to use the V6 tcf, due to the teletype driver issue, probably the easist thing is that I could make up a miniature disk image (RK05, if you have that available), with both the V6 bootstap, and tcf on it. Otherwise, I might be able to cobble something together; a hacked version of tcf including the console driver, or something like that. > Something that XXDP can load would be useful. I know nothing of almost any DEC software, alas - I'm assuming it can handle .LDA files, but I don't know which format it prefers. > From: Christian Corti > I enhanced DTF with some useful messages and error/status output. IIRC > the "original" version produced no messages at all. Having just looked at the original :-), it did have two messages: "ready drive 0 and type y" and "tcf: error" (Shades of 'ed'.... :-) Noel

OT: Excessive bounce notices?

I get hit by that every couple of weeks. ?I still have no idea what a 'bounce' is or what I'm doing or not doing to cause it to drop me. ?Kind of frustrating because it just drops me and then I miss chunks of conversations I'm watching.

The original Sun-1 workstation one more time

by rlloken＠telus.net

I made some silly noise about a Sun-1 owner's manual recently (and I still haven't sent it out). Today, while browsing in the morgue I found an apparantly unused CDC Lark cartridge with a factory label declaring it to be Unix 1.1 boot media. Is there a functional CDC Lark surviving some place? Sure isn't one here. -- Richard Loken VE6BSV, Systems Programmer - VMS : "...underneath those Athabasca University : tuques we wear, our Athabasca, Alberta Canada : heads are naked!" ** rlloken at telus.net ** : - Arthur Black

MACRO11

by j_hoppe＠t-online.de

Hi, my version of the MACRO11 cross-assembler for PDP-11 is now on https://github.com/j-hoppe/MACRO11 . Among others it fixes the "JMP Rn is illegal" error on "jmp (rx)" opcode. Also I added the option "listhex" to produce a binary listing in hex notation instead of octal. I found this really necessary when analyzing test programs with a modern logic analyzer. Joerg

General TC11 DECtape diagnostic/formatter questions

by jnc＠mercury.lcs.mit.edu

> From: Josh Dersch > If I run them on SIMH configured as an 11/44, I see the same behavior. > If I run them on SIMH configured as an 11/20, then I get the printout > described in the documentation and listings. ... I haven't yet dug in > to see what accounts for the difference -- any ideas? The fact that the simulator produces identical results to the real hardware would argue that it's not a bug in that particular hardware. So it must be some real difference between the two. There are subtle differences between the 11/20, and other 11's - e.g. on the /20 SWAB does't clear the V bit - maybe it's one of them? It might be worth trying setting the CPU type to other values, and see if it works on any other machine type. > 2) I'm looking for means to format DECtapes on the TC11. ... The > maintenance manual only indicates "a special program supplied with the > TC11 system," and I haven't managed to find it. The UNIX V6 distro includes a standalone program, tcf.s, to format DECtapes. I don't know if you have a running V6 system (real or emulated) to assemble it one; if you want me to assemble it and provide it as binary (in a variety of formats, e.g. .LDA format), let me know.

ISO Telenex/Atlantic Research protocol analyzer tech manuals

by aek＠bitsavers.org

another rathole :-( picked up some ST125 mfm drives and a multibus-ish floppy/mfm controller on ebay that came from a AR/Telenex 8600 Autoscope, which is a high-level protocol analyzer because it used an example of a hard disk controller chip I had never seen used before (Signetics 68454) http://www.ebay.com/itm/282236398895 found the manual for the 7000 series on line, and just bought a whole 8600 Turbo http://www.ebay.com/itm/331829268184 so now I'm looking for software and manuals for that. fortunately, it looks like the software is still on the hard disk in the one I bought.
