Is anyone familar with this stuff? I picked up a pile of it a week or two back. The pod that I'm looking at right now if for the 6800/02/08 but I think the others are for other CPUs. Anyone know what system it's for? The interface board uses the same type female connectors as the ss-50 stuff but many more pins and much larger circuit card. I found some mentions on the net but nothing useful. Joe

Drool on www.pdp-11.nl/homebrew/pdp8/pdp8startpage.html or www.pdp-11.nl/homebrew/cons1170/cons70startpage.html Have a *good* look at the front panel of the SBC6120, and compare it with a real pdp8/e. You will notice that a few switches are missing. Then check out my front panel ... Given the Blinkenlight board set, you can build a replica yourself either by (a lot of) DYI, or by grabbing a panel of eBay and make a box around it. I am waiting on the arrival of an order of IDC headers for the I/O Board to finish the 11/70 console ... - Henk, PA8PDP. BTW, I will finish the 11/70 console and the first chap that offers $10,000.- will get it :-) - working, running RT11, Advent and perhaps RSX with the chasing light pattern ...

I don't know what macros are used, and what they do. Remember, I don't really know RT-11. But, like I said, it might be that just commenting that line out, and see what macros fail will give you enough clues to what is missing that you can either safely remove that, or write those macros on your own.

DEC Gigi terminal

That was the VS-100, which is of historical interest because it was was what the X Window system was developed on. GIGIs are raster termials using the REGIS command set. "REGIS graphics GIGI" turns up a few interesting google hits.

HP 106B Quartz Frequency Standard?

by bobalan＠sbcglobal.net

I scanned the two pages from the 1967 HP catalog. You can find it here: http://www.dvq.com/docs/hp106_107.pdf It's a very nice quartz standard.

Can anyone tell me anything about it?

HP 106B Quartz Frequency Standard?

by lee＠geekdot.com

> I can't find this in any of the catalogs that I have. Can anyone tell > me anything about it? A heated XTAL oscillator used to derive 5MHz, 1MHz and 100KHz reference outputs. Short term stability is probably around 1 part in 10^11 with long term stability an order worse. Units like this are often used as the master reference at HF, MF and LF transmitter sites and should be calibrated periodically against a better reference like a Rubidium standard. Without calibration this is just as accurate as any XTAL source as the frequency can usually be adjusted over 1 part in 10^7 and have a fine tune (which if I remember the HP unit is a voltage input) that has a range of 1 part in 10^8 Lee.

Tektronix PEP301 mystery resolved

by legalize＠xmission.com

OK, still sifting through this big pile o' stuff from DoveBid :-) Some of you may recall that the lot included a PEP301 16 MHz System Controller and I didn't know what it was. Well, its an IEEE-488 system controller built as an interface card and software combination for a 386 PC clone. Its all branded with Tektronix logos though: main unit, monitor and keyboard. Although there were no seals, it appears new in box with a full set of manuals and software diskettes. The manuals are a stock set of manuals for PC clones of the era (GW-BASIC, MS-DOS 3.3, owner's manual for the PC) and a manual for the Tektronix HPIB software utilities. There is this little dinky pamphlet sort of manual for the keyboard. People seem to be selling that online for some reason as if you need help in figuring out a standard 101-key IBM PC keyboard? I'll be scanning the Tektronix manual and uploading at some point and try to make some disk images of the non-standard software bits. -- "The Direct3D Graphics Pipeline"-- code samples, sample chapter, FAQ: <http://www.xmission.com/~legalize/book/> Pilgrimage: Utah's annual demoparty <http://pilgrimage.scene.org>
