L. Conway

by Murray McCullough

Today I came across an obituary of Lynn Conway, computer pioneer in the field of VLSI(along with Carver Mead) and also in one called dynamic instruction scheduling(used in supercomputing world). More to the point Conway was transgender and suffered for this, an almost forgotten pioneer in the microcomputing and supercomputing fields. Also, as a researcher at IBM and Xerox Parc where she contributed to the first years of microcomputing, the GUI and Ethernet protocol development. Eventually the IEEE recognized her contributions as did IBM - better late than never! Murray 🙂

But for those who couldn't make it over to Texas for this VCF, here is a summary of a few things there.

Experience using an Altair 8800 ("Personal computer" from 70s)

by Dave Dunfield

I case anyone is interested... I've just passed on my "Mits Altair 8800" - this is a very historic system from the 70s - it is: First Personal Computer (long before IBM PC) First S100 buss system First system Bill Gates wrote code for (long before Microsoft) I did write a pretty decent emulator for my exact Altair system some years ago... And with recent interest in the system, I've just updated it with a few minor improvements and a "cleaned up" edition of the software I created to bootstrap a hardware front-panel based system (no on-board ROM) via a serial port card - requiring you to enter only 18 bytes through the front panel So .. if you'd like to experience what it was like to use a system from the 70s - here's some of the things you can do: Bootstrap it cold Run NorthStar DOS (one of the first commercial DOSes) Run DMF (Device Management Facility) - a DOS I created for it - can you tell that at the time I was working on an IBM mainframe ... my - OS name sounds a lot like various IBM mainframe packages at the time. A few other software setups (for example there's a stand-alone bootable FORTH) Has Editors, Assemblers, BASIC and other tools from the era. and a few games - some written by yours truly - some very early commercial offerings (like "Cranston Manor Adventure", or "Valdez") Note1: My Altair emulator was created under DOS and is a 16 bit program! It does work very well with DosBox (I recommend the one on my site) Note2: I've not updated the ALTAIR.ZIP on "Daves Old Computers" yet - you can get the updated one from: "Daves Old Computers" -> Personal -> Downloads -> OlderDownloadsFromPrevious - look for "ALTAIR" under: Simulators and Emulators *** I don't follow this list nearly as much these days - if you want to reach me, use the contact link on my site! -- ---------------------------------------------------------------------------------- Search "Dave's Old Computers" see "my personal" at bottom!

Re: Vintage computing in the San Francisco bay area

by Anders Sandahl

Hi! It's many interesting things here. I hope I can pass by Anchor Electronics. When I was looking on the map where to find it I noticed that Intel (and it's museum) is just a few blocks away. I think I'll miss Electronics flea market, I have read abut this in another context as well. It would have been great fun! We will miss the observatory's free views. Well, I have to stay longer the next time. /Anders On 2024-06-14 19:32, Curious Marc wrote: > If you happen to be there on the right Sunday, don’t miss the > electronics flea market! > Electronics Flea Market <https://www.electronicsfleamarket.com/> > electronicsfleamarket.com <https://www.electronicsfleamarket.com/> > favicon.ico <https://www.electronicsfleamarket.com/> > > <https://www.electronicsfleamarket.com/> > Also if you need old ICs and transistors at 1960’s prices, that odd > connector or the big old Sprague capacitor there is Anchor Electronics: > Anchor Electronics <https://anchor-electronics.com/> > anchor-electronics.com <https://anchor-electronics.com/> > favicon.ico <https://anchor-electronics.com/> > > <https://anchor-electronics.com/> > > You could view a lot, bid on it and pick it up at Auction BDI > Hibid <https://auctionbdi.hibid.com/> > auctionbdi.hibid.com <https://auctionbdi.hibid.com/> > <https://auctionbdi.hibid.com/> > > <https://auctionbdi.hibid.com/> > > Also take advantage of the clear California skies with telescope > viewing nights at the Foothill Observatory or at the Chabot Museum, > or, even better, at the Lick observatory > Foothill College Observatory - Foothill College > <https://foothill.edu/astronomy/observatory.html> > foothill.edu <https://foothill.edu/astronomy/observatory.html> > favicon.ico <https://foothill.edu/astronomy/observatory.html> > > <https://foothill.edu/astronomy/observatory.html> > https://chabotspace.org/events/free-telescope-viewings/ > lh_domes_wide.jpg > Public Evening Tours > <https://www.lickobservatory.org/events/public-evening-tours/> > lickobservatory.org > <https://www.lickobservatory.org/events/public-evening-tours/> > > <https://www.lickobservatory.org/events/public-evening-tours/> > > Marc > >> On Jun 13, 2024, at 12:15 PM, anders--- via cctalk >> <cctalk(a)classiccmp.org> wrote: >> >> Hi, >> >> Soon I will travel to US and San Francisco/San José Area.

tape duplicator program for pdp11

by Jacob Ritorto

Hi, Just got a real (Cipher M990 on TS05-emulating controller) tape drive running and would like to make exact copies of some [9-track] tapes "to guard against disaster." Probably will also do some imaging, so bonus if the candidate program can handle that too. This is on an 11/34; I don't have a good q-bus tape controller yet or I'd try it on uVAX with NetBSD or something less "exciting" :) Anyone know of good programs to do this with only one tape drive? Don't care which operating system. Been looking through DECUS archives but have found nothing yet (manually reading thru - 1/3 of the way done, maybe there's a better way to scan these?). thx jake
