The LA Times called it the first computer store in a story in December 1975. The first ad for the store ran in July of that year. I've put scans of the article and the ad here: https://photos.app.goo.gl/S53vBGs6irzqoLR37 > Message: 7 > Date: Sat, 22 Aug 2020 22:02:53 -0700 (PDT) > From: Fred Cisin <cisin at xenosoft.com> > To: "General Discussion: On-Topic and Off-Topic Posts" > <cctalk at classiccmp.org> > Subject: Re: Computer stores > Message-ID: <Pine.LNX.4.64.2008222156370.19726 at shell.lmi.net> > Content-Type: TEXT/PLAIN; charset=utf-8; format=flowed > > When dozens or hundreds start up within weeks or months of each > other, > every one is important, and most are interesting, but "FIRST" or > "STARTED > THE TREND" (implying being the "first") cease to really mean anything. > > It's generally better to never use the word "FIRST"; there is almost > always a lesser known one that was earlier. > > The trend from being a sideline within a business, to becoming the > primary focus of the business can seem anticlimactic, but is what marks > the core of the transition. > Think of Fry's, NLS, etc. > > > On Sat, 22 Aug 2020, jim stephens via cctalk wrote: > > > > > > > On 8/22/2020 9:53 AM, Chuck Guzis via cctalk wrote: > >> On 8/22/20 8:52 AM, Murray McCullough via cctalk wrote: > >>> 45 yrs. ago last month, mid-July, Dick Heiser started a new > industry, the > >>> retail computer store.

old data books?

by uban＠ubanproductions.com

I'm trying to reduce the amount of "stuff" I have and I've been carrying around a significant number of old data books. My plan has always been to have all of the resources I need in my retirement (assuming I get there) to work on and repair the various vintage computing hardware I've also collected over time and have been storing. My question is if I this information is all now available online or if I need to keep these data books. My guess is that it is some of both. Also, if I decide to part with these, should I create a list and make them available for the cost of shipping or just recycle them? Maybe someone collects them? --tom

Dolch (DLI) Logic Analyzer C100 Disassembler Roms?

by holm＠freibergnet.de

Hi guys, I have three Dolch Logic Analyzers, the two bigger ones are Palas <someting> Analyzers, one of them with an highspeed option, the third is an Compact 100 Analyzer. For the bigger ones I have Disassemblers for 8080/8085 and Z80 as far as I know. I want to use the C100 with a Z80 disassembler, but the ROM images are different it seems, the roms don't work in the C100. Has anyone the rom images for the C100 Z80 disassembler? Kind Regards, Holm -- Technik Service u.

Computer stores

by c.murray.mccullough＠gmail.com

45 yrs. ago last month, mid-July, Dick Heiser started a new industry, the retail computer store. It opened in West L.A. under the name Arrow Head COmputer Company. aka, The Computer Store. This began the direct marketing of microcomputers to hobbyists, later to the masses of the middle class, albeit a small market 45 yrs. ago. Happy computing. Murray ?

SIMH on low overhead platform

by ccth6600＠gmail.com

Has SIMH been ported to a low overhead (instant-on) platform? I ask the question because the startup time of Linux is distracting when powering on a PiDP-11/70 or similar clone systems based on SIMH. Thanks Tom Hunter

Alto II keyset connector plug identification

by steven＠malikoff.com

Would anyone be able to identify the 19 pin connector used on the Alto II keyset? Shown in the second photo on https://www.computerhistory.org/collections/catalog/X124.82C The Xerox engineering doc (209962B_Alto_II_Assembly_Keyset.pdf) has it as P/N DE51218-1 if I interpret it correctly. I've looked for a while and the closest I can find appears to be Mouser p/n 2DEF19P The cost of 136 USD (each!) is more than I (and perhaps everyone else) would really like to pay, and that's only for the male end. Ideally I would like a datasheet on this original connector if possible, to know the pin-pin spacing and the pressed metal surround dimensions. I've just ordered small trial quantities of screws, microswitches, e-clips, nutserts, rods and so on for my keyset lookalikes/workalikes. Also about to start the key mapping to F5-F9 using a popular small SOC board, which is small enough to be inside a custom printed shell that the keyset plugs into. That is, the 3-row 19-pin female connector side which goes through to USB. I was thinking there's no reason it shouldn't be able to work using the original connector with a real keyset-less Alto, should any such animal be lurking out there. Hence looking at the feasibility of placing in a 19 pin male-female connector arrangement rather than the fallback of straight-through to USB. The whole thing is still at prototype stage so even if it doesn't work out, well I will at least have a bunch of additions to my nuts/bolts/fasteners/switches stash. Thanks for any help, Steve.
