Vegetation is one challenge - failing infrastructure is the bigger one ... i.e. my main router developed a hard short in one of the 100+ SMD caps - was challenging to find I scanned the manual, but my scanner sometimes hicked up at the pagesize - so some pages are slightly larger There were two...

Ok, will try if I get my old doubleside scanner working reliable But in the northern hemisphere garden work is overdue, we just had the last frostnight So my current priorities are somewhat on the boring (digging) side...

I guess this is the older version ?? I do not find the EK-VSTAB-MG version These are the only manuals I found about VS2k in my library

What I found in the pile of paper - mostly multiple paper copies in mixed quality PC100 Motherboard 54-15486-01 PC100B Motherboard 54-16206-01 PC100B Memory Extension H7842D PSU Test procedure/Specs H7842 PSU Circuit Diagrams VT100 Monitor board No other "interesting" stuff so far...

I did not read through the whole thread - but I got the impression that no complete circuit diagrams of the adapter exist ? Many years ago I inherited a pile of paper copies from a former collegue who worked in the DEC repair center There are some diagrams of this PC100A 8087/Memory adapter...

I have a few DC12 from a former DEC Repaircenter, so the are genuine for sure I am based in Austria You can have two for free, not worth to send the few euros... But I am not going to fill any customs forms - not sure if this will go through ? I would flatten the pins, so they fit in an normal...

I worked for DEC at this time, but cannot remember any real issues with RA92 in my accounts On the RP07 (ISS Univac ?) in comparison, I got lots of HDA problems This was not a hermetic sealed HDA, it was open at the back where the Voicecoil sits It was extremly delicate to handle, once the...

Looks like HSC70 Storage Controller Modules to me HSC70 used a J11 Processor from the IPB: Module, K.PLI (PLI Port Control) L0107-YA * Module, PILA (Packet Buffer Board) L0109-00 * Module, ILI (CI Link Interface) (deleted) L0100-00 * Module, CI Link Interface (added) L0118-00 00011 * Module...

I used 60 degree Centigrade for 4 hrs with sticky TK50 Tapes After this I could read 20 out of 22 Tapes written 25 years ago TLZ04 DAT Tapes of similar age all worked without baking

Hi, I have a similar plan to get a fullsize bezel some day ... No urgency on my side, lots of other projects Here is the STL file from the PiDP-11 - should be ok for an easier start I could imagine to print it in pieces and than glue it together, apply a filler coat and paint it Quite a few...

I can offer you my original XXDP tape from my DEC Service times I think I created this in 1978 and it booted to XXDP and contained some diags I never used it again and it was stored since in a dry environment No clue if it would still work, but I can send it to you in Sweden if you like (I am...

Not sure if this helps here: When I worked in DEC Fieldservice and had to find a short in a 11/70 Backplane between two Signals I connected a continuity beeper to one signal Then I stacked two extender boards and runned the second probe slowly over the extender traces until it beeped This had...

Roland, I just checked my pile of opto modules (I worked 17 years at DEC...) There are some unidentified boards with embedded optoparts I have no clue if they are useful for you and where they came from here is a detail view with a 4148 Diode for comparison There are some other modules - even...
