Can anyone tell me what this is? Also I was able to get this all for 25$ The 637cd works great but haven't been able to test the 660av since I need a special connector to get it to work with this monitor. Also if anyone has a connector to hook this monitor up to the 660av please let me know. Thanks Jim >> that 660av is a nice machine! I got one for $25 in a 24/1G configuration and got the matching applevision display with it. There is a special adaptor that connected the applevision and 660av together because the applevision display has speakers, mic and ADB plugs on it. IIRC on mine, it was a funny shaped box and a thick cable which plugged into it. thankfully the 660av has a standard macII series video connection so any of the mac monitors of that time will still work with it.

RamKeeper fires?

by dlw＠trailingedge.com

Asking for info on the cards in my new IIgs, I'm getting stories that the Applied Engineering RAMKeeper was reportedly the cause of a couple of houses burning down. Anyone have anything on this or is it just another UL? I hadn't planned on really using the card and someone wants to trade me for it but maybe I should hold on to it just for the "history". :-) ----- David Williams - Computer Packrat dlw(a)trailingedge.com http://www.trailingedge.com

Another tech legend for discussion!

Although I run Squeak under Windows and on a Power Mac, I still prefer running the original Xerox Smalltalk-80 VI2.2 under System 6 on a Mac. I have it on a IIci, but the IIci has a Radius Rocket in it, and the virtual machine doesn't like its 68040. I have a Mac IIfx I'll be running it on in the near future, at almost twice the speed of the IIci's '030. I'll have to run the benchmarks, but I think it runs at 0.5 Dolphin. -dq > > cheers > > > -----Original Message----- > > From: Douglas Quebbeman [mailto:dhquebbeman@theestopinalgroup.com] > > Sent: 14 July 2000 13:58 > > To: 'classiccmp(a)classiccmp.org' > > Subject: RE: Another tech legend for discussion! > > > > > > I have it on good authority that Smalltalk-80 was not ported > > to the Star. > > It was running on the Alto and the Dolphin at the time, as > > well as another > > Xerox workstation whose name I can't recall.

I have it on good authority that Smalltalk-80 was not ported to the Star. It was running on the Alto and the Dolphin at the time, as well as another Xerox workstation whose name I can't recall. Larry Teslar was working at PARC at the time, and ended up following Jobs back to Apple, because Xerox couldn't get their asses in gear and Apple looked like it knew what it was doing (w/r/t getting new technology out the door). For those interested in what Smalltalk-80 feels like to play with, you should try Squeak, a successor developed by some of Smalltalk-80's authors, Alan Kay and Dan Ingalls, at Disney. Squeak is everything ST80 was and more. You can find info about Squeak at: http://www.create.ucsb.edu/squeak/ > 2 of the main developers of the Mac platform were Bruce Horn > and Jef Raskin, their side of things can be found here: Bruce Horn also "did time" at PARC, working on Smalltalk-80. -doug q > http://www.apple-history.com/quickgallery.html?where=lisa.html > > Follow the link at the bottom of the screen.

RCS/RI Open House

by aw288＠osfn.org

I suppose I ought to start advertising on the list. Anyway, the Retrocomputing Society of Rhode Island will be holding this month's open house on the 15th of the month, next Saturday, at our Millspace in Providence, Rhode Island. Directions can be found on our websight at <www.osfn.org/rcs>. This month's topic is the machines of MAI/Basic Four. Essentially, we will be examining just what we have in this line, as we have really done little with the machines since we obtained them. We will also be discussing a possible move to another room in the building, our recently arrived Symbolics machines, the electrical upgrade, future open house topics, and so on. There will also be a great deal of general computer geek talk. Please email me (or the list) with any questions. All are invited. No charge! William Donzelli aw288(a)osfn.org

Micom

I kept some pieces, most notably the 8-inch Tandon floppies and the daisywheel printer. Gave one Tandon away. It was 8080a based, IIRC. Have never tried the printer, strangely enough. Could be what I had was somrthing else, tho... -dq

SY/LINK Network Interface, Square-D PLC Network I/F card, ISA

by whdawson＠mlynk.com

I found this type SFI-534 card in an IBM 5155 I recently bought. No software for it was on the 5155's hard drive (21mb Seagate). What is intriguing is what is on this board: MC6809P (socketed) MC6850P MC6840P MC6854P HY6264P-10 (x2) HD46504P/HD6844P AM2130-12PC (socketed) 27264-25 EPROM (socketed) DB9M and DB9F The board is switch selectable to be addressed anywhere from CA000-CA3FF through D3000-D33FF. It looks like it can be a lot of fun to play with if I can find any information (I.E. Schematics, etc.). From what I've found out so far, this board uses RS-422 for communication. All the receivers/drivers and protection circuitry is under the metal cover. Anyone know anything about this board? There's one very similar to it on eBay now: http://cgi.ebay.com/aw-cgi/eBayISAPI.dll?ViewItem&item=381126929 ,with photo. I put a $0.01 bid on it just so I can easily track the action, so if anyone else wants one of these boards, feel free to bid on it also. I have no desire, yet, to own another one.

Unresistable pond comment

by agraham＠ccat.co.uk

I assume you mean something like a VAX 11/730 rather than the ol' Austin Morris car of the same name? :) Actually, I would't tarnish a VAX by roping a politician to one, so how about an AS/400 instead? <ducks to avoid possible dec/ibm war> -----Original Message----- From: Steve Robertson [mailto:steverob@hotoffice.com] Sent: 14 July 2000 15:33 To: classiccmp(a)classiccmp.org Subject: RE: Unresistable pond comment > > There's just one thing wrong with that idea: it would be extremely > > cruel to the plants and creatures living in the pond. > Would you want > > to be a plant, fish or frog and have a politician plopped into your > > pond? > > > The only time I think this would be a truly good idea is when the > pond happened to be stocked with Pirahna. > Or... 14 feet deep :-) To keep this on topic, perhaps we should use an old mini instead of concrete.

Xerox DayBreak

And modifying the scan rate was exactly what I tried to do. I had a schematic of the monitor, all transistor, and with careful twiddling of some resistors and capacitors I was able to change both sync rates (HSYNC is more dangerous since it is coupled with the fly-back converter that generates all those high voltages needed to make electrons move).

I think I have one that was modified for another use later (inconvenient pin snipped off).
