OT: Datasheet for Motorola MCM62940 32K X 9 SRAM?

They should be very similar. I imagine the difference is that the XX486 version has adaptations for the 80486 methods of addressing memory, while the 940 version is more oriented for the Motorola family of processors. At least, I think I read something to that effect somewhere--maybe in the description of the associated tag RAM. Anyway, I've emailed Brent and hope to pay to ship the whole databook. If anyone else decides they want to order the 4000 soldered down static RAMs I referenced (they have 19 batches in stock), I can scan the datasheet after I have the book--if I can get the scanner working again. Darned glass fell out because the manufacturer's double sided tape got old (it's more than 10 years old too). I tried a 3M tape <http://www.shop3m.com/3m-high-performance-double-coated-tape-9088-fl3znfcqj…> that looked promising but it didn't hold. I'm going to try again and heat the tape and give it three days to set. On the first try I didn't see the information that the adhesive needs to set for three days. Who knew that one needs to read the datasheet on *adhesive tape* in order to use it properly? Jeff Walther

The tape drive is a TU77 or TU78, which you should know Pontus... ;-) My guess would be a TU77 though. Anyway, no, the graphics is not DEC. And no, it's not a serial connection. If you ever tried doing bitmap graphics over a serial line you should all realize that a high resolution picture like that would take a very long time to download over a serial line, even at 19200. And by 1986 you didn't have any faster serial ports on a Unibus-machine. Also, DEC didn't have any high-resolution hardware for Unibus. The closes was the VS11, VS60 and that kind of stuff. And those don't get close to the type of resolution, number of colors, or speed of this thing. DEC did play with a few tablets for the VAX stations by this time, but hadn't come that far. So, yes, this is a third party thing. The two companies that springs to my mind here are Intergraph, who did CAD systems based on VAXen. They usually based their systems on the VAX-11/750, but I don't think there was any technical reason that an 11/780 shouldn't be possible as well. The other is Evans and Sutherland, who specialized in high performance graphic subsystems. My guess would be that this was some E&S graphic system, but it's hard to tell, since I never actually saw any of their stuff in real life. But I think it was/is a whole bunch of cards on the Unibus, and video cables to a color monitor. And of course input ports for keyboard and tablet. There might have been other players around as well. But I know of no DEC hardware that could produce better than aboout 256x256 on Unibus machines, and only with a very limited palette. And it's definitely not a VT-whatever. The "best" VT-terminal, in terms of graphic is the VT340, which have a fair resolution of about 240x800 (roughly from memory), but at most 16 colors, out of a palette of 4096. But it's also newer than 1986, and don't look like that at all.

Fwd: [comp.sys.dec] BASIC-Plus-2

by nigel.d.williams＠gmail.com

Has anyone managed to get any of the Layered Products installed on RSTS/E V9.X (X >= 6)? Aside from F77 for which there was a declaration of success here: http://mailman.trailing-edge.com/pipermail/simh/2008-March/001719.html I tried with BASIC Plus 2 V2.6 (with RSTS/E 9.6) and can see that the tape appears to be a BACKUP INSTAL.BCK set, but RESTORE is refusing to work with the tape (TPC file). Does anyone happen to have the BP2 installation guide or tips on how the layered products are generally installed on RSTS/E? A related question: Can anyone explain what a field-test versions of RSTS/E means? is it a release candidate (in modern parlance) or a beta? I see RSTS/E V10 but it is annotated with field-test so I assume it was not the final shipping version. thanks. www.retroComputingTasmania.com

help navigating the DECUS archive

by tshoppa＠wmata.com

I have several of the DECUS sig tapes as images, and also extracted files. I think 11SP42 is one of them. Like most of the 70's and 80's post-paper-tape RSTS stuff it's a DOS-11 style magtape. Will put it up on ftp.trailing-edge.com<ftp://ftp.trailing-edge.com> tonight. Tim.

Separating a Vax 11/780 from it's peripheral cabinet...

by ian_primus＠yahoo.com

Anyone happen to know how the Vax 11/780 and the single-wide corporate peripheral cabinet are joined together? The Vax has good casters, the peripheral cabinet has stupid casters, and they're joined at the hip. Are there hidden bolts or latches, or some kind of joiner panel like on the 11/750? -Ian

When it eventually appears on BitSavers it will be interesting to compare with the half inch (TM4) version I have. Could you please tell me (or the list) when it goes up. Roger Holmes.

I'm pretty sure when I learned typography the numbers I was taught was that Cicero was 6 lines to the inch, and that it was a 12 point font. Maybe neither of those numbers are actually correct. That was all before I had used computers although I think it's possible that Postscript was a glimmer in someone's eye by that point. I briefly used an IBM Composer and I'm pretty sure that defined a point = 1/72 inch before postscript ever did, although it seems likely that it didn't originate the 1/72 measure either. Most computer line printers were six lines to the inch, 66 lines to 11 inch page. This was set by geartrain if nothing else :-). I think the Model 33 is the same. > If you think *this* mailing list goes off-topic from time to time, you should > check out the Letpress mailing list, for metal type and ink folks. Knuth's Metafont book closely brought together for me, for the first time, computers and typography, and they've been closely linked for me ever since. I could've sword that I read that a point = 1/72 inch in there but despite some desparate scouring he uses "point" as base unit with absolutely no attempt to map it into inches. Tim.
