CYCLOID faceplate for Altair computer...

by wh.sudbrink＠verizon.net

I seem to remember this being discussed many years ago, but I can't find it. Anyway, there's an Altair on epay right now with a CYCLOID faceplate. If I remember correctly, this is just a replacement plastic insert that was sold simply to "freshen up" an Altair where the original had worn badly, as so many did. I've done a fair amount of searching but I can't find an ad or other reference to the product. Does anyone recall the time period? I would assume it was at least a couple of years after the introduction of the Altair. 78 or 79? A pointer to an advertisement or one of those "new product" paragraphs that many of the magazines did back then would be most helpful.

I remember this very well. I was living in Santa Monica at the time, and drove down Pico Boulevard almost every day. Needless to say, I immediately noticed the "Computer Store" sign and stopped in, soon becoming one of the regular "hangers on". Dick Heiser and his wife Lois were taking a big chance, but it proved to be a good bet. Initially, their business consisted of buying Altair 8800 kits and assembling them in the back of the store. A lot of people were happy to pay extra to not have to solder all those hundreds of connections. Dick was a regular fixture at meetings of the Southern California Computer Society (SCCS), often making deliveries and taking orders there. In those days, SCCS monthly meetings were *the* place for computer geeks to get together and exchange news and get help. A few months later, two guys named Steve showed up at a meeting with a kit they called the "Apple I", for the grand price of $666.66. I wish I had had the foresight to buy one! Instead, I wound up joining the SCCS group purchase of DEC LSI-11 systems. I still have that system, with a case and power supply from a TRW surplus sale. It isn't worth nearly as much as an original Apple I, though! :-) Alan "Hindsight is 20-20" Frisbie

The answer tells us whether they were explicitly > planning on making other models later! I honestly do not recall if they used the "I" or not. This was, after all, 45 years ago! At that time there were many tiny startup companies trying to get our attention, most of which sank without a trace. If I had been asked back then which ones I thought would survive, I probably would not have picked Apple. Not my first mistake, and certainly not my last. :-) Those *were* exciting days, with new products and developments happening every month. I looked forward to every SCCS meeting, with people showing off their latest homebrew project, swapping tips, and buying parts & boards. For a while, there was even a large wheel of cheese which we eagerly devoured. :-) Alan Frisbie

"That might be true for discussions where people don't care to do any research, or where words like "first" are uses more for hyperbolic emphasis, but suggesting someone started an industry on a list like this, I think, doesn't seem out of place." I agree that using ?*first**?* has a certain connotation. However, until it is proven otherwise it?s quite appropriate. If this word were not used, by me or anyone else, on this website then we never get to learn anything ? *new*?. Even in historical writing, of which I?ve done some as a historian, one has to acknowledge a source, but I for the life of me can?t remember as I didn?t have the source on my electronic-research rolodex. In such an occasion, as the note I sent to cctalk, should have stated this. My apologies. Happy computing!

Diskless VMS install

by john＠ziaspace.com

Hi, I have a VAXstation 4000/60 with an internal disk but no CD drive. I'd like to install VMS (7.3), but I'm new to VMS. I have a SIMH VAX instance running on the same LAN with VMS installed (mounting the VMS images is easy, of course). Can anyone point me to a HOW-TO which explains how to use one VMS system to MOP / netboot another system to install VMS? Thanks, John

1U VAX, was: Re: Computer stores

> I was going to comment that the only way I could see a 1U VAX was if > someone rack mounted a 4000/VLC. Is that the stock VLC power supply? > My cluster doesn?t even have that much space. > > What do you use to go from SATA to SCSI (SCSI-1 even)? It's a standard 1U power supply with a custom adapter. You can see it better here: https://twitter.com/AnachronistJohn/status/1294725819038752768 I use a SATA to IDE adapter, then an IDE to UW-SCSI adapter, then an UW-SCSI cable and terminator, then finally a 68 to 50 pin adapter. The previous drive was a Samsung SSD, but I think that constant, non-stop swap use wore it out. This was the smallest new spinning rust drive I could find. SCSI2SD would work for a while, but, again, swap usage would wear out an SD card in no time, I'm sure. John

That might be true for discussions where people don't care to do any research, or where words like "first" are uses more for hyperbolic emphasis, but suggesting someone started an industry on a list like this, I think, doesn't seem out of place. If someone has examples of this being wrong, he / she will say so, and we'll all learn. If not, the original message has conveyed useful information. Relatedly, I have what I think is the only 1U VAX in the world. I've mentioned this in many places, but if someone says I'm wrong and shows me an example of another, it would please me, not upset me. I'll have learned of another :) John

Computer Stores

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.

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?

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.
