I've managed to come across a 'Votrax Personal Speech System'. I've found some information from google, but haven't found out some important things like what the pinout is on the power connector (it's a DIN-5). While I can just trace the traces back to chips on the circuit board, it's proven hard to disassemble, so I'd rather not if I don't have to. Does anyone have enough information about this thing to tell me how it wants to be powered? Oh, and another thing. I've recently picked up a few 2-4VUPS VAXstations that I'm working on trying to turn into a VMS cluster. I'm hoping to create a public-access system - I remember seeing an article about another one on SlashDot a few months ago. Because of the terms of the hobbyist license, I'll need to make it a non-commercial-use-only cluster, but I'd like to make it available to list members or other people to mess around with.

Tranfer of Files From RSX-11------II

by badoni_nk＠yahoo.com

Hello John Thankyou very much for your kind reply. Yes it is a complete system. I have checked Kermit in this system but I could not find this S/W there. Might be my process was wrong. And if it is there how can I access Kermit(how to find wheather Kermit is there or not). Is there any command for Kermit. Please suggest me how to find wheather Kermit is there or not. /******** Incase if kermit will not be installed then how can I transfer the data. ********/ Basically it is the text data which I want to transfer to the winnt PC. This system is having 8" floopy drive & I also wants to transfer files from 8" floopies to PC. These files are important for me & I want to make backup for these files into the another PC having WIN NT. Please advice me I will be very thankful to you. I am in India.

HP 9000 "Nova" I-class systems

by jwillis＠arielusa.com

Stan: My CDs were created from ISO images. The files were something like hpux_11_0_disk1.iso.gz and hpux_11_0_disk2.iso.gz I labeled the disks accordingly, and have tried both. Haven't gotten a chance to examine the sectors yet. Will do that now since I'm up with a horrendous case of the flu anyway. :P Thanks! --- John Willis Field Service Engineer Ariel Technologies 505.524.6860 voice 505.524.6863 fax jwillis(a)arielusa.com -----Original Message----- From: Stan Sieler Sent: Tue 2/18/2003 12:26 PM To: John Willis; cctalk(a)classiccmp.org Cc: Subject: RE: HP 9000 "Nova" I-class systems Re: > and I finally got a copy of HP-UX 11.0, but when I try > to boot off the CD (boot 52.2.0.0), it says "Bad LIF magic."

HP-IB Mass Storage Emulation (Help)

by vp＠mcs.drexel.edu

I have been working for some time on a pet project to make a mass storage emulator for HP-IB systems. Given the massive improvement in capacity that has taken place the past 10 years, most mass storage devices from the 80s look pathetic. For example, take the HP 9133H which is a massive unit that can store about 5Mb. Even the compact flash cards that are bundled with popular digital cameras can do better than that. I started my project by trying to utilize the HP-IB drivers that are part of the NetBSD Open Source Unix clone (which runs on the HP 300 series), but I have come to realize that the HP-IB cards are the creating a new legacy issue. Open Source drivers for HP-IB cards are very hard to find and thus any solution that depends on them becomes de facto legacy (once the card itself is no longer sold, finding the card becomes almost as difficult as finding HP 9133H drives). So I looked hard at the HP-IB bus itself (using the schematics from the Series 80 adaptor) and it looks like a simple parallel bus. So why use a custom card, if the PC parallel port can be adapted to drive an HP-IB bus. If the PC parallel port can be used, then I can port the NetBSD drivers to use the parallel port, rather than the HP 300 HP-IB interface. The NetBSD drivers also support SS-80 compatible mass storage devices, which means that the implementation can be verified against a real HP-IB mass storage device. If this works than the drivers will have to be modified so that they become a mass storage "server" rather than a "client" (i.e. a device that responds to mass storage requests, instead of a computer that issues such requests). Small i386 compatible single board computers are easily procurable and embedded versions of *BSD and Linux systems run on these SBCs (they even accept compact flash cards or more traditional hard disks). This means that we can make a mass storage device that can physically fit inside the cabinet of the main unit (e.g. Integral PC, or HP-87). Anybody willing to provide assistance to this effort, is welcome to contact me. However, I think that going through this list may be more beneficial so that other people can contribute in the technical discussion. **vp

HP 9000 "Nova" I-class systems

by jwillis＠arielusa.com

The system came with no hard drives, no media, and the 4mm tape and CD-ROM were disconnected from the SCSI chain. I was able to get the thing put back together, and I finally got a copy of HP-UX 11.0, but when I try to boot off the CD (boot 52.2.0.0), it says "Bad LIF magic." I'm told this means the media is not bootable. So my question is... how does one install HP-UX if the CD is not bootable? -----Original Message----- From: Bob Brown Sent: Fri 2/14/2003 9:56 AM To: cctalk(a)classiccmp.org Cc: Subject: Re: HP 9000 "Nova" I-class systems What's your question (I support several of these boxes..an 827, a G40 and an H70). -Bob >Anyone out there have experience with HP 9000 "Nova" class systems? >Specifically the 9000/800 I40 especially, but any in the class. > >John bbrown(a)harper.cc.il.us #### #### Bob Brown - KB9LFR Harper Community College ## ## ## Systems Administrator Palatine IL USA #### #### Saved by grace [demime 1.01a removed an attachment of type application/ms-tnef which had a name of winmail.dat]

> Yes, those damned dirty A-rabs. We all know for a > fact that they use the profits to finance terrorism > because Colin Powell showed us a pretty graphic > that proved it. All those people who have doubts > are just stupid. I don't want to start a to-do on this list, but I couldn't let this pass.. Colin Powell showed real evidence that some people who happen to be from the Middle East (Not sure if Hussein and his people are Arabs) are doing some bad stuff. The discussion is about bad people who happen to be Arab. Not that all Arabs are bad people. And it so happens, that a lot of terrorists in the world today are from the Middle East. Used to be, terrorists were Northern Irish... The fact that some of the worst incidents have been perpetrated by people from the Middle East does not make Americans, British or others wrong for noticing it. If anything, it means that it calls for others in the Middle East to speak up and use the social pressures or peers to put a stop to their fellow citizens (all these bad people must be SOMEONE'S brothers, sisters, sons, daughters, cousins, neighbors...) doing all this bad stuff. The displeasure that is aimed towards Middle Eastern people from people in the West is because this isn't happening. People are being killed daily, and instead of having Millions of people stand up and protest that.... We have millions of people stand up and protest somebody trying to put a stop to it. Yes, I think that's stupid. And I think the people who condemn the police instead of the criminals, are stupid... > We all know a good A-rab is a dead A-rab. Fuck > them. Let's go in there and take their precious > oil from them so they can never use the profits > to finance terrorism anymore. That'll end all > terrorism forever and ever and we can live happily > ever after guzzling all the free oil we want. Not all American's or Westerners believe this. While I would like that Terrorists get no money at all, from any source. And I'm pretty sure lots of Saudi money does indeed go to support terrorism. Drug money from Poppy sales also goes there, and other money goes there also. I would like to see the oil money stay in the Middle East, but used to feed and care for the people there. To provide water, sanitation, schooling, and good lives for the people in Middle Eastern countries. Rather than being spent on Terrorism, Weapons of Mass Destruction or persecution of Non Muslim peoples. That is VERY frustrating for Americans. I contribute money to charities all the time, and just get sick when I think of all the Billions of Dollars spent on weapons and death that instead should have been spent on life and making the lives of people better. People who are Anti-American, and Anti-Bush just don't know the truth about Americans or George Bush. They buy all sorts of stories that aren't true. Make up motivations that aren't real. We liberated Kuwait, but if you notice did not take the country over. We returned it to the rightful rulers. We've done the same throughout history. History shows that Americans aren't interested in ruling the world, only liberating other people to be free and happy. So, let's get back to discussing Classic Computers... Regards, Al

Designing around a 6502 (was Re: Assembly on a Apple IIc+)

by dwightk.elvey＠amd.com

Hi There was some software multitasking done on 6502's, as well as other machines. This was done in Forth ( both preemptive and various round robin taskers ). Forth has the advantage that a task state can be saved with just two pointers. You do need to swap task at word boundaries. This can cause a little latency if it is a interrupt driven tasker. ( "word" here refers to the minimum executable unit of the Forth engine and not the address size ).
