Hi, I'm looking for engineering info on the MSV11-J. I was unable to find any prints online, or even a technical manual. (I have the User Manual, but it doesn't have much detail.) The main issue I'm after is working out which bits go into which chips. I have some other QBUS memory boards with no documentation where I created the mapping by just pulling chips, e.g.: http://gunkies.org/wiki/Q-RAM_11 but, alas, on all the MSV11-J's I've seen, the DRAM chips are not socketed - unlike QBUS memory boards by almost all the other manufacturers (e.g. National Semiconductor, Camintonn, etc - in fact, pretty much everyone _except_ DEC). Anyway, if anyone _does_ have an MSV11-J with the chips in sockets, I'd _really_ appreciate hearing from them! I'm not sure it's going to be possible to work it out from looking at board traces, since the MSV11-J is ECC memory, and I expect all the data lines just disappear into the two huge gate array chips. Anyway, I would appreciate hearing from anyone with anything on the MSV11-J. Noel

XpressWare v8.1 or above (software for Tektronix X11 terminals)

by carlojpisani＠gmail.com

hi, In 1990s Tektronix produced digital video X terminal and introduced X server software based on VxWorks v5 (Windriver). Later they introduced a new line of terminals, at some point a company called NCD bought the Tektronix X11-terminals division and started to produce their own line, called NCD-terminals with a software called "NCD-bridge" Anyway, both the 200-series and the 400-series of the Tektronix X11 terminals boot from a directory on a server via NFS or TFTP, either way, you need to create a directory for the terminal to boot from, and install a number of files. These files are provided as "Tektronix XpressWare version 8.0 (or later)". The 200-series can bootstrap from v7 ( one of the member of my team owns an original CD), but the 200-series needs the v8 or later (we don't have). Unofficially, you might look for NCD, the Company who bought the X-terminals division from Tektronix; they had (note the past tense) some software in the form of patches, accessible by anonymous ftp. There aren't any complete releases, but there were archives which contains much that is useful to be found in the ftp, in particular patches containing bits of version 8.1 of XpressWare; enough to form the basis of a working installation. Unfortunately, the archive is gone, no more available. Let me know if you have the software or if you know where/how to find it, otherwise, X11-terminals like X400 can't be functional. Thanks

DEC FPJ11-AA

by pbirkel＠gmail.com

https://www.ebay.com/itm/DEC-PDP-11-84-M8190-AE-Module-FPJ11-AA/113112634277 IMO a really good deal on an 18 Mhz FPJ11-AA. Those don't seem to come up much . Not my item, but I have previously purchased from this seller and he's reliable. -----

DEC FPJ11-AA

> From: Bill Gunshannon > Anybody have any PMI memory modules they might let go for less than my > first born male child? The DEC PMI memories are the MSV11-J and (I think) the MSV11-R. The latter is rare, but the -J's can be found. VARx sold me some -JE's a couple of years back for a good deal less than their listing price: http://www.varx.com/CAT/MEMORY-DEC_MSVXX.HTML The other possibility is that Clearpoint made some PMI memories, which one can occasionally find on eBait, etc: the QED1 (aka QED-F) and DCME-Q4E (they look the same, so I'm not sure if they are actually different, or if the names were just changed for marketing reasons). Alas, I know of no documentation on either. (If anyone has any, _please_ share it!) I am slowly trying to work out how to configure them (they can be configured to run PMI or normal QBUS); contact me privately for what little I have so far. Noel

DEC FPJ11-AA

by jnc＠mercury.lcs.mit.edu

> From: Pete Turnbull > Bill would want the -JD (2MB) version (the -JE version is 4MB so too > big). Err, the -JD is 1MB, and the -JE is 2MB (see e.g. EK-MSV1J-UG-001, pg. 1-3). Noel

DEC FPJ11-AA

> From: Paul Birkel > Same thing in this case. The CPU looks to see a PMI signal that is generated by the KTJ11 - no signal -> 11/83. My impression is that except for the speed of the J11 (and the crystal), and whether or not it came with the FPJ11, all four of the M8190 board variants are otherwise identical. Whether it's a /73, /83 or /84 depends entirely on whether it has/sees PMI memory and the KTJ11-B UNIBUS converter (and the correct backplane, for the latter, of course). > The 11/84 is an 11/83 extended by a Unibus interface to support legacy > peripherals. It has a special backplane which is mostly UNIBUS slots, with a few QBUS/PMI slots on the front, and a 'special' slot in the middle into which the UNIBUS adapter goes. Noel
