The key is MSCP is not a trivial protocal and the underlying hardware to do that requires muscle in the form of a fast cpu.

On the other hand, if Its pretty easy to fine drives inthe 2-9gb range still and they are cheap. The idea of such huge drive with RT11 and friends is that is wasted. I use D540s (31mb) and swap them like carts as I have a bunch of em and they are plenty big enough. Drives in the 120-400MB range are plentyful for me, one 200mb drive would take all the binaries and sources I have with room to spare that aren't already on Tims CD. Whats the point? The value of IDE on Qbus is cheap easy to find drives in the sub (at the time) 1gb class. Allison

Changing logicals on VMS?

by cmcmanis＠mcmanis.com

Hi Paul, This isn't an allocation class issue. Its something I brought on myself, and for that am paying the price :-). My true question is whether or not I'm going to be stuck re-installing VMS, however given the way VMS works I'm sure there is some voodoo to fix it. I got in this mess as follows: I installed an RF72 drive into my 4000/200 and proceeded to do a 'sho dev' on it. It showed up on the DSSI bus as $24$DIA264: I then installed VMS 7.2 on to this drive, followed by a bunch of layered products. Then I read in the KA660 technical manual how to "talk" to the DSSI drives, (which is very arcane using the KFQSA but a snap on the KA640 and KA660) and proceeded to tell the drive to call itself node SYSTEM and unit 0. This worked fine, and I noted that I could now boot the system by specifying DIA0: rather than DIA264: (which I never could remember anyway). Then I went to install another layered product. That installation failed because it couldn't find a file is was expecting in SYS$SYSDEVICE:[SY0.SYSTEMP] (or something very similar). So I did a dir SYS$SYSDEVICE: and sure enough there was nothing there, then I did a SHOW LOGICALS and from there discovered that SYS$SYSDEVICE: was defined to be $24$DIA264: (the original name of the DSSI drive) Now I could name it back again. But I'd rather tell VMS where the SYSDEVICE now sits (for all the system, like on a permanent basis). If I 'define' it, it changes for the current process but doesn't change universally and more importantly other things are stuck that way to. Nothing is SYSTARTUP_VMS.COM defines these so they must be in a parameter database somewhere else. That is where I'm looking now ... On a somewhat related note, I went out and forked over $100 for a true 5 port switch so that I can put my VLC cluster on a switch! Now all I need is a console multiplexor. --Chuck At 08:35 PM 10/2/00 -0500, you wrote: >The system$dia0 isn't especially newer or better.

Need help or service manual for RS COCO mini disk 26-3022...

You sure it isn't the first drives for the TRS-80? The symptom would be the older SA400 drives designed for 35 track operation used within. The later drives were SA400Ls that were designed for 40 track operation. Both used the spiral groove cam but one was a bit different. Open up the box and see which you have. The other possibility is old (really old) media ment for the 35 track drives and this media has a smaller "window" in the jacket that will limit head travel. >They can't read a disk formatted on a good drive.

ebay bid lists

by cmcmanis＠mcmanis.com

Has anyone else noticed that last night Ebay changed the way they display bids to include _all_ bids, even repeats by the same person. Interesting bit of information that is. And to bring it on topic, there is a VAX 4000/VLC* (nothing special) that is up to $170! That's pretty amazing, and to think I sold one at the VCF for $40 :-) --Chuck * Ebay item #461408005

True colors

by kyrrin＠bluefeathertech.com

This one is truly in the "For what it's worth" department. Following the recent flamewar between Mr. Ismail and R.D. Davis, I forwarded a (supposedly private) note with my concerns about it to the DNS provider for the domain siconic.com (psyber.com). I did this because many ISP's have explicit prohibitions in their terms of service against exactly the kind of crap that was going down. Apparently, the tech person for psyber and Mr. Ismail are on pretty good terms. I got the attached blurb this evening. If anyone on the list had any doubts as to what appears to be Mr. Ismail's true nature, I suspect they will now be removed. Yes, I've filter-filed the entire 'siconic.com' domain out of my system.

IBM Series/1 Minicomputer

by univac2＠earthlink.net

Someone is offering me an IBM Series/1 minicomputer with all manuals, an 8" diskette drive, and a CDC Hard disk, for $100 plus shipping. Shipping for the processor will be about $25, and between $50 and $75 for the diskette drive. Shipping for the hard disk will be hundreds, so I won't be getting it. I have three questions: 1. What can y'all tell me about everything? I know almost nothing about it. 2. Is it worth getting the processor, manuals, and diskette drive,? It comes with some disks, but I don't know what's on them. 3. Does anyone have an operating system for it? Thanks, Owen

DSSI: What was it like?

DEC's proprietary DSSI interface: Can anyone give me some idea of why DEC came up with it, what benefits it offered over, say, SCSI, and whether it was entirely proprietary or related to something like IPI? For that matter, what the heck did DSSI abbreviate? My guess: Distributed Storage Subsystem Interface. Web sites, FAQs, or commentary are all welcome as this is pure curiousity on my part.

At the time it was developed SCSI was maybe SCSI-1 or II and way short on perfomance, limited in number of possible connected devices and short on cable length. DSSI like many of the DEC storage interconnect was trying to address problems like cable length (wanted longer), rate of transmission(faster) and cluster interconnect. It's also a protocal and within that it addresses best ways to move data faster and route it. > For that matter, what the heck did DSSI abbreviate? My guess: Distributed >Storage Subsystem Interface.

Intel MDS 225 and Intel 310 info

by Innfogra＠aol.com

I, too, have one of these kicking around. Mine has a bad Ball Monitor inside. I believe the MDS 225 is the Development System III mentioned in Joe's documents in an earlier post. I used to play with these about 9 years ago when we bought truckloads from Intel. If you have questions contact me off list. Most info has been covered on the other posts. I think it is worth collecting. There are not many in the hands of hobbyists and collectors. I used to have CPM for this system but I am not sure I still do. If I find it I will let the list know. I bet InBus Engineering still has cards and parts for these systems, if not docs and SW. I know I sold them thousands of dollars worth of parts, especially for the 310 systems many years ago. I still have some 310 multibus systems & parts. Their contact info is : compumart(a)inbus.com 925-454-2561 voice 925-454-2501 fax InBus Engineering, 6233 Industrial Way Livermore, CA 94550 Unfortunately they realize they have almost the sole supply for these old systems and their prices used to reflect that. I haven't talked with them in years but they still advertise in Compu-Mart and the Processor. Paxton Portland, OR

From: Neil Cherry <ncherry(a)home.net> >BTW is it easy to design boards for the Microvax. This Analog board seems >really simple. Designing an intelligent SCSI board wouldn't be a lot more >difficult (I didn't say anything about the Vax driver). MVII is a Q-bus machine and like it's compatable Q-bus PDP-11s that went before and during its a reasonably easy bus to interface to and DEC did a fair job of makeing the documentation for it easy to get. Designing a PIO SCSI card would be easy, DMA a bit harder but there is no secrets there either. Programming is another thing though as the Q-bus is an annex of the processor address space and DMA between memory (on private(PMI) bus) and QBUS devices is more complex programming. However RQDX (disks), DEQNA/DELQA (NIC) do the dma trick so that is already known. Allison

110VAC in Automobile About 6 years I found that Radio Shack has a plug in the cigarette lighter converter to 110v.

The van was also dragging a small 2 wheel trailer. You could feel the engine labor sometimes in the mountains. I took ear plugs, disney movie music rots your brain.

Linux as in RH5.2 is good on them but Caldara Openlinux2.3 is a bit too fat for them. Allison

Of course my main system is only at 20% :^) An Alpha with 96mb is running faster than the VAX however with 24mb so you get what you pay for. However in the time frame when they were both current that Alpha would likely have had 128mb minimum and likely more and the vax would have been big at 32mb. It's the difference between the byte oriented VAX and the Word orieneted Alpha. >I understand why OpenVMS on an Alpha uses so much memory as opposed to on a >VAX, however, the fact remains, it's a memory hog, and like I said based on >my very limited Tru64 experience it seems even worse on the exact same >hardware. Actually any os on Alpha will be bigger by 4x, it's the instruction granularity mostly and also the Alpha is actally less CISC than VAX. The payback is the 64bit addressing and math. Allison

by ip500＠home.com

Is any one privy to the workings of an the Intel 310? The one I have is missing a monitor and keyboard and hookup is not immediatly obvious to me. Also has labeled ports on the back for ethernet, console, cube. I'm assuming it was the control box for my newly acquired iPSC/1 system. This one is a model "PSYP310", 286/12 8 mhz, 1 meg mem, 140 mb, 45 mb streaming tape & a floppy drive. Any info appreciated...manual or copy greatly! appreciated.... Craig

New find - OSI Challenger 4P

by r.stek＠snet.net

Wheeee! I got an OSI Challenger 4P today (does this complete my collection of early micros with walnut sides? I now have my Sol and NorthStar Horizon and Challenger.) Of course it would be even better if it worked or at least I had some documentation. A shielded cable terminating in an RCA phono plug exits the cabinet. The fan turns and apparently something is being output. I tried a mono composite monitor with no luck, but channel 11 (?) seems to give what could be a screen image with several inverse video blocks scattered down the left side (we have a STRONG channel 3 here, and 4 is garbage). Pressing "return" shows no change in the screen, nor does pressing a momentary-contact switch (home-brewed?) above the keyboard labeled "Break Enable." Since I never even saw one of these in the 70's, I could use some help. Does anyone have docs they would be willing to copy for a reasonable fee? Any other advice cheerfully accepted.

[PayPal] PayPal to start charging for what used to be free!

by mac＠Wireless.Com

Well, the Beginning of the End for PayPal, as I see it. I predicted it. It's happening. Oh well! Now can you see why I detest this low-life pond scum operation? -Mike ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ PayPal Raises Fees, Looks For New CEO and Profits By STACY FORSTER October 10, 2000 PayPal.com delivered a popular solution to a vexing problem -- how to send and receive money over the Internet. But the bigger challenge for the two-year-old start-up will be to make money in the process. With its sights set on profitability and an initial public offering, PayPal's parent company, closely held X.com, is looking for a new chief executive officer. On Sunday, Elon Musk, the founder and chief executive of X.com (www.x.com), said he is stepping down to allow the company to bring in a leader with more experience. "Elon has had great start-up experience, but he's never run a major public company," says Peter Thiel, chairman of X.com. Mr. Thiel says he expects the company to be profitable by the end of 2001. And in move that may be controversial, PayPal will begin charging some consumers fees on Oct. 16 for a service that used to be free. The company, which had depended largely on interest income on cash in its customers' accounts, plans to charge a fee of 1.9% plus 25 cents per transaction for anyone who receives more than $500 in credit-card payments in a six-month period. Before, only businesses were charged the fee. "They're struggling to come up with the business model," says James VanDyke, an analyst with New York e-commerce research firm Jupiter Communications. PayPal, which launched its service in October 1999, merged with X.com in March. Analysts say the combined company dominates the online person-to-person payment business, boasting nearly four million customers and 300,000 business accounts. Each day, PayPal completes about 130,000 transactions and moves about $6 million. PayPal says it is accepted by more than half the auctions on eBay, compared with only 10% for its closest competitor, Billpoint (www.billpoint.com), a joint venture between eBay Inc. and Wells Fargo & Co. PayPal's registered users can send payments to anyone with an e-mail address by writing a dollar amount on a form at the company Web site. When the e-mail is sent, the payment is charged to the sender's bank or credit-card account. If the receivers aren't registered, they can fill out a form attached to the e-payment to receive the money, which is waiting in a PayPal account in the receiver's name. PayPal has grown rapidly by encouraging users to recommend the service to friends and families, offering a $5 reward for opening an account or referring a new customer. But all that has been costly. "They now need to create a strategy that walks the tightrope between maintaining the critical mass of customers and figuring out a way to make money," says Paul Jamieson, a financial services analyst for e-commerce research firm Gomez Advisors in Lincoln, Mass. And some customers already are angry. Peter Resnik, a financial consultant from Nokomis, Fla., who conducts about 100 auctions a month for antique paper items on eBay, says he feels duped by advertisements promoting PayPal as a free service. He contends those advertisements were aimed at the auction sellers who helped PayPal develop its large customer base. "They led you down the path with the impression that this was a free service and there were no strings attached," Mr. Resnik says. PayPal first began charging fees when it introduced business accounts in June, says X.com spokesman Vincent Sollitto. Mr. Sollitto says they PayPal is implementing the new policy because some people were using the personal accounts for business purposes to avoid fees. Mr. Thiel says the new policy will affect only about 250,000 customers, or 6%, of its customer base of four million. Users were notified about the policy change last week in an e-mail. X.com's competitors vary on their policies for credit-card transactions. Ecount.com (www.ecount.com), PayMe.com (www.payme.com) and PayPlace.com (www.payplace.com) do not charge for credit-card transactions. For transactions of more than $15, Billpoint charges 1.75% plus 35 cents a transaction for business accounts and 2.5% plus 35 cents a transaction for personal accounts. EMoneyMail (www.emoneymail.com), a payment service offered by BankOne Corp., charges customers $1 to send money, but there is no cost to receive funds.
