General TC11 DECtape diagnostic/formatter questions

by derschjo＠gmail.com

Hi all -- I'm working on getting a TC11 + TU56 running at the LCM+L. We plan to use it as a tool for various archival and restoration efforts. After restoring the power supplies, I have it lashed up to a PDP-11/44 -- I know this is anachronistic, but it's been a workhorse machine with ethernet and SCSI, which makes it very flexible. So far, so good. I have RT-11 running and it can read and write tapes, although the left TU56 transport seems to be a bit marginal. I am running into a couple of issues, and I'm curious if anyone else out there has experience here and might be able to shed some light before I spend a lot of time on it: 1) In bringing the TC11 up, I've been attempting to run the TC11 diagnostics, with mixed success. ZTCB runs, but reports an error with the ENDZ status bit not being set properly. So far as I can tell, ENDZ *is* being set on normal operations, but I haven't exhaustively debugged the controller yet. The other four diagnostics (ZTCA, ZTCC, ZTCD, and ZTCE) do nothing when run -- nothing is printed and there is no response. 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. (See bitsavers -- http://bitsavers.informatik.uni-stuttgart.de/pdf/dec/pdp11/xxdp/diag_listin…). I haven't yet dug in to see what accounts for the difference -- any ideas? 2) I'm looking for means to format DECtapes on the TC11. I have a few marginal tapes and I'd like to see if reformatting them brings them back to life. The maintenance manual only indicates "a special program supplied with the TC11 system," and I haven't managed to find it. I *have* found this: http://mirrors.pdp-11.ru/inf.informatik.uni-stuttgart.de/pdp11/dtf.mac which I've assembled and run on RT-11 and it goes through the motions of writing out the timing and mark tracks, but when it goes through the second pass to write out the block numbers it fails immediately, with either status 001207 (indicating a "Data Missed" error) or 020033 (Mark Track Error). I haven't yet hooked up a scope to see if the T&M tracks are *actually* being written, but given my experience with the diagnostics in (1) above, I'm not averse to thinking there may be more than meets the eye with this issue. So in a nutshell: Anyone used a TC11 on a later PDP-11 (like the 11/44)? Anyone have any thoughts on the diagnostics and formatter issues? Thanks as always, Josh

NCD19 / Xncd19

by seefriek＠gmail.com

> Is the 701 based on the RacerX from LSI? Good question...nice shout-out for an obscure MIPS variant. The Explora 700 is, however, not a RacerX, but an R4700. With up to 256MB of RAM. Which is nice. KJ

KIM-1 Debugging tool

by dkelvey＠hotmail.com

I've been making a debugging ROM board to test out the various parts of the KIM-1. It is based on taking over the KIM at reset and running test. So far I've got two test working. One is a basic, is it running test that just blinks a light on the debug board. The next is a test of the first 1K of RAM. A little tricky to do without RAM. I expect to write some more for the RRIOT ics. If anyone has interest, they can follow me on the Vintage Computer Forum or contact me here. The board has 3 ttl ICs, a 2764/27128 EPROM, a couple LEDs and a dip switch. Also a few pullup resistors and capacitors. Dwight

NCD19 / Xncd19

by seefriek＠gmail.com

From: Rico Pajarola <rp at servium.ch> > Does no one have NCDWare 3.2.1 or earlier? Nostalgia...I really liked the NCD 19 I used many moons ago. Reasonably snappy at the time, nice mono screen, quiet. Funny enough I recently resurrected an NCD Explora 701 (much later MIPS-based xterminal). It's wildly faster than the 19 (with 10/100 enet instead of just 10), but it's interesting to see how far modern X implementation has diverged from NCDs time: 8-bit pseudo-color is a showstopper for a lot of things, various desktops (Gnome, KDE, etc.) break in strange ways if they run at all, lot's of contemporary code has issues on 64-bit systems (like my old xview/olvwm code). TWM still works fine, as does the butt-ugly built in NCD Motif-ish window manager. Haven't had much time to work on it, but I'd like to get something like i3 running. I bet Mouse can add more color commentary. Reminds me...need to see if I can still get the Mouse terminal emulator to run. Probably also need to get an SCO ODT or SVR4 VM running for that old school feel. I know I've got at least one 3.x release, but not sure which one or what's in it. FWIW, I've also got some 4.x, a 5.0.x and 5.1.x; running 5.1.140 on the 700. I'm in Dublin until next week so won't be able to check until then. Ping me directly if you don't hear from me by, say, Thursday. P.S. - If anyone has an NCD 700-series or HMX (esp HMXpro24) they don't want, let me know. KJ

Perq 1 troubles

by tmfdmike＠gmail.com

Just on the off-chance... does anyone have schematics for the Perq 1 portrait monitor? Mine is sick... and there are none on bitsavers. On first power-up there was a faint raster pattern but that quickly vanished and now there's no sign of life from the tube heaters... Thanks Mike http://www.corestore.org 'No greater love hath a man than he lay down his life for his brother. Not for millions, not for glory, not for fame. For one person, in the dark, where no one will ever know or see.'

1993 Mt. Xinu calendar

by aperry＠snowmoose.com

In a box of my old stuff, I found a copy of the Mt. Xinu calendar for 1993, the last year that they did a calendar, and scanned it. Some of you may fondly remember the Mt. Xinu calendars so I am hosting what I scanned so folks can download it. It can be found at: http://wildwestrally.org/afp/IMG_20161110_0001.pdf. Enjoy, alan

NCD19 / Xncd19

by rp＠servium.ch

Hi all I'm trying to resurrect my NCD19 for vcfe.ch but I can't find the firmware for it (I have half a dozen different versions of NCDware, but most don't contain the boot images, and none have the binary for the ncd19, only ncd15b, ncd19r, ncd19c etc. which don't work). And all links I find on the internet are dead ;( I appreciate any help tracking that down. Rico

SPRAGUE capacitor for Tektronix 4051.

by mattislind＠gmail.com

One of the DC filter capacitors has gone open circuit in my Tektronix 4051. It is a SPRAGUE 9600 uF - 30VDC with a little bit unusual foot print. It might be common for other Tek equipment. Google turned up one Ebay-hit for a completed auction but that's it. Anyone has a reliable source for this type of capacitor: http://i.imgur.com/P0Nz5KW.jpg
