Problems with Ersatz-11 and CDROM

by jhfinepw4z＠compsys.to

I realize that there are probably very few individuals interested in this topic, however here goes. I am running E11 (Ersatz-11) under Windows 98 so that I can run RT-11. It works great in almost all respects and I can even live with this one minor problem. However, perhaps someone might be able to suggest what needs to be fixed. I have just acquired a CD-RW and been successful is making copies of my files to a CD-R and over the past week a few test files to a CD-Erasable. I am using "Nero Burning" as the software which "writes" to the CD and while I am a bit disappointed that the write speed to the erasables is only 2x as opposed to 16x for the WORM media, I can easily live with that and it is not a problem. I have also discovered how to "DUMP" to the screen any of the 2048 byte blocks on the CD - in hex of course. And finally, I discovered how to copy a single file to the CD starting at block zero of the CD media - or at least I have done so with the erasable media and I hope it can be done with the WORM media as well. The only thing I have not found out as yet is how to copy all of the sectors written to a CD back to a file on the hard drive so that more than one copy can be made to more blank CDs. I doubt if that will be a problem - I just have not even bothered as yet to try. When I copy a single file to the CD using Nero and the "File" menu o File o Burn Image o Open o Foreign Image Settings - Block Mode 1 - Block Size (2048 Bytes) - Image Header (0 Bytes) - Image Trailer (0 Bytes) o OK o Ignore - during this test, the Image file is not a multiple of 2048 bytes o Write where each "o" indicates another menu sub-level. Nero does correctly write the file to the CD as far as I can tell - except perhaps for the last few blocks since the size of the image file was not a multiple of 2048 bytes. Using C:foobar.DSK as the Image File I wrote to the CD, then using Nero and "Recorder"/"View Track", I can look at each 2048 byte block the CD to verify that the Image File Foobar.DSK was written to the CD and under E11 I can give the commands: MOUNT DU0: CDROME:/RO MOUNT DU1: C:foobar.DSK/RO Then under RT-11, I can also give the commands DIFFERENCES/BINARY/DEVICE DU0: DU1:/START:64./END:last-block-3 which results in a perfect compare. Under RT-11, I can also do a DUMP/TERM DU1:/ONLY:any block including block numbers between zero and 63. DUMP/TERM DU0:/ONLY:only block numbers 64. or greater. NOW!! Here is my problem and the question. Why can't E11 read blocks zero to 63. on the CD? I can see them under Nero and DUMP these blocks to the monitor under Nero. I could easily modify the MSCP device driver for RT-11 and automatically add 64. to every block number before I try to read it from the CD, but that would really mean a new device driver (CDX.SYS seems like a good name). I would also need to decide if that should be just for partition zero (my preference) or all the 20 or even 21 partitions on the CD. Or perhaps, someone has already discovered the answer why Nero can read those blocks under Windows 98, but E11 can't. By the way, one other solution is to just not use partition zero under RT-11 under E11 under W95/W98. Before I could burn my own CDs, that was the way that Tim Shoppa set up the RT-11 Freeware CD in any case. However, now that I have been able to actually read blocks zero through 63. from the CD under Nero, it seems too soon to give up on E11. I suspect that a partial answer may be that Nero uses W95/W98 operating system calls that are not used by E11 which is essentially a DOS program. If true, that obstacle might be overcome if the modification to E11 is simple enough. PLEASE!!! Can anyone suggest what the difficulty might be?

FYI: Yahoo Mail Account info Alert. (fwd)

by doc＠mdrconsult.com

I know a lot of y'all use Yahoo Mail.... FYI to those who use Yahoo Mail. March 29 - Tired of spam you're getting at your free Yahoo! e-mail account? Get ready for more. Tucked inside a privacy policy change the company made this week was notice that more Yahoo! e-mail marketing offers were coming "even if users had formerly indicated they were unwanted. YAHOO! GRANTED ITSELF PERMISSION to spam by creating a new "marketing preferences" page that lets users pick "yes or no" to specific categories of marketing pitches. The problem is, Yahoo! set every users' option to "yes" - even if long ago, they indicated they never wanted any Yahoo! spam. Users who don't want marketing offers from Yahoo have 60 days to do the following: Visit the user profile preferences page at http://edit.my.yahoo.com/config/eval_profile select "Edit your marketing preferences" from within the Member Information section; and individually change selections in a series of marketing categories from "yes" to "no." In e-mail marketing lingo, the process is known as "opt-out." But even performing that slightly cumbersome operation is no guarantee that Yahoo! marketing offers won't come, since the firm reserves the right to add marketing categories at any time. "I'd suggest re-checking periodically," writes another mailing list poster.

A cheap crap soldering iron (like the $7 specials that I used to by at Radio Shack when I was a kid) will produce crap results for pretty much ANY person regardless of skill or experience. I used a Weller TCP like Tony's for many years; it was wonderful in every way. About 6-8 months ago I picked up a Metcal iron (an SP-PW1-10), which is even a huge step above said venerable Weller TCP...I recommend them very highly. Try one and you'll understand what I mean. :-) It really doesn't pay to use cheap soldering irons. You'll save a few bucks, but it'll cost you parts, boards, fingers, and the fun of soldering! -Dave -- Dave McGuire "...it's leaving me this unpleasant, St. Petersburg, FL damp feeling on my shorts..." -Sridhar

It was pretty In 1985-1987 I worked at Princeton University (I think I may have mentioned this at one point) on the Navier-Stokes Supercomputer project at the Moody Fluid Dynamics Laboratory. I was responsible for the Switching Board, a big board full of TTL that functioned as a big crossbar switch between processors and memory planes. The boards in the NSC machine were Unibus form-factor; we used the OEM version of the PDP11/24 chassis which came with no labels and no backplane wiring. The Switching Board was wall-to-wall 74LS series chips...mostly 74LS244s...packed as closely as possible. If memory serves they were 14,000 wires per board or so. Doing that without a gun would have been...well, impossible. It was tedious, but I enjoyed it anyway. What was especially enjoyable was seeing the first test program running through vectors, outperforming a uniprocessor Cray XMP on $2K worth of hardware in a desktop chassis. :) -Dave -- Dave McGuire "...it's leaving me this unpleasant, St. Petersburg, FL damp feeling on my shorts..." -Sridhar

Add a decent keyboard and bump the RAM to 64KB. You'll want a printer and a good cassette recorder, too. If you don't plan to add any hardware which requires a ROM, then you might want to add NVRAM to the unoccupied 8-16K address space. A Hunter board is perfect for this, if you can find one.

If you have access to another mac, you could burn a bootable CD preconfigured with what you want, boot from it (provided you can still use the letter C on the keyboard), and then access the Mac via VNC (or whatever you setup on the CD). Or, you could just check eBay, as new ADB keyboard for that computer will likely be found for around $5. (mouse being about the same cost) -chris <http://www.mythtech.net>

Neat trick I just thought of!

by fernande＠internet1.net

I just bought a IBM PS/2 Model 9577 today for $10. It's got some areas of sticky sticker residue on it. Usually, I use "Goo Gone" to remove that type of thing. A lot of times I need to let it sit and soak. The Goo Gone tends to flow to other areas, However, which can make a mess, and waste the stuff too. I decided to use toilet paper to control the flow. Basically, I used a single sheet or even less, lay it over the desired area, and soak it with the Goo Gone. The toilet paper controls the Goo Gone by surface tension..... at least I assume it's the surface tension between the toilet paper, case, and the Goo Gone. Let it soak, then you can pretty much wipe the area clean :-) -- Chad Fernandez Michigan, USA

UCSD P-System & "compile once, run anywhere"

by sieler＠allegro.com

Hi, A friend was claiming that with the UCSD P-System, one could "compile once" and then "run anywhere" (where "anywhere" means different kinds of computers running the P-System, not different instances of the same computer). Was this true? Did users commonly compile on system A and then take the P-Code to system B and run it successfully? I'd have thought that media incompatibility would have tended to limit this capability. Was any commerical P-System software sold that was a single binary, but the vendor expected the user to be able to install/run it on any brand/model of P-System? (Or, did vendors have to produce a version for every platform?) thanks, Stan Sieler sieler(a)allegro.com Stan Sieler sieler(a)allegro.com www.allegro.com/sieler/wanted/index.html www.allegro.com/sieler

A few old Commodores

by kenziem＠sympatico.ca

I received a call saying there was a few old commodores to rescue. I called and he mentioned a couple of 64's, a vic 20 and a B128. I pick up several boxes, when I get them open there is a Pet 4032 inside one of them with the B128 keyboard. there is a 103 modem, and another bookshelf worth of games, programs and a bunch of old Popular Electronics and Radio-electronics including one with an article entitled 'Hobby computer Main-Frames'. Lot's of extra cables a few dongles, a D9090 hard drive, . A capture card 2 beat up 64's.

Osborne 1 disk drives (was RE: 5.25" floppy model numbers)

by Robert_Feldman＠jdedwards.com

Osborne also replaced the electronics on the drive with their own board. My O1 had Siemens FDD 100-5 drives. I have the cable pinout and disk controller schematics in my copy of the Osborne 1 Technical manual, if anyone wants a copy. Question: the tech manual says that with the double density option installed, the O1 could read/write IBM 40 track 8 (512 byte) sectors, Xerox 820 40 track, 18 (128 byte) sectors, and DEC 1820 DD 40 track 9 (512 byte) sectors.

Osborne Floppy Drives

The ribbon cable to the card edge carries drive >power as well as signals and is wired differently. You will need to >conjure an adapter to use normal ones. I have an Osborne 1 that has had dead video for a while. Since it is a spare anyway, I would be willing to disassemble the drives, and send them to the original poster (Erik, I think?). I'd also try to save any cables, connectors, screws, etc. One caveat... this O1 has had dead video since I got it, so I have never fully tested out the floppies... I suppose at some point I could have swapped them into a working O1, but I never had the time.... If the original poster could email me off-list, we can exchange shipping information. I will not charge for the drives, but because they're not light, I'd appreciate reimbursement for shipping.... Thanks!

I am under the impression that the same cable used for the DECstation 5000 series is also used with the DEC 3000 series of machines. Given that, a BC18P (or BC18Z) is not compatible. Although I don't have a complete pinout on the BC18P, I do know that pin 3 of the BC18P (pins 1,2,3 of the BC18Z) is used for video. For the 5000 (and hopefully the 3000) the first few pins are used for the keybaord. And Doc <doc(a)mdrconsult.com> added: > The kbd/mouse dongle pinouts are posted on the web somewhere. Try > Googling "dec 3000/300x pinout" or something. I looked briefly last > night and can't find it, but it's out there. Having not found the 5000 cable pinout myself, I did a pinout for it some time back. I will paste it to the end of this and we will go from there. Mike DECstation 5000 keyboard/mouse cable and related info --------------- --------------- --------------- --------------- --------------- The DECstation 5000 has a 15 pin (male) D connector on the back for keyboard and mouse connections. There is a cable that plugs into the 5000 connector and has a keyboard socket (RJ-11) and a mouse socket (7 pin mini-din) on the other end. I am under the impression that the same cable is also used with the DEC 3000 series of machines. The part number for the cable is 17-02640-01. For a keyboard, use a LK201 or LK401. For a mouse, use a VSXXX-AA (round hockey puck) or VSXXX-GA (rectangular). CABLE INFO The cable pinout (from the DECstation 5000/240 manual) is: Pin Signal Desc. 1 GND Ground (to keyboard socket) 2 KEY.TX Keyboard transmitted data 3 KEY.RX Keyboard received data 4 +12v Keyboard power 5 GND Ground 6 MSE.RX Mouse received data 7 MSE.TX Mouse transmitted data 8 GND Ground (to mouse socket) 9 GND Ground (to mouse socket) 10 NC 11 NC 12 NC 13 +5v Mouse power 14 -12v Mouse power 15 GND Ground (to mouse socket) I have also verified the above info with a VOM. KEYBOARD INFO As for the keyboard, I had a couple of them open a while back (to clean out the cookie crumbs) and traced them out somewhat. Looking into the end of the plug on the cable coming from the keyboard. |------------| | o o o o | | B R G Y | |___| |___| |____| B - Black - Data from keyboard R - Red - +12v to keyboard G - Green - Ground Y - Yellow - Data to keyboard And looking into the socket on the end of the 17-02640-01 cable: (also applies to the keyboard socket on a terminal such as a VT420) |------------| | o o o o | | Y G R B | |___| |___| |____| Pin Y to pin 3 of the 15 pin D connector on cable 17-02640-01 G to pin 1 ... R to pin 4 ... B to pin 2 ... I do not include pin numbers for the keyboard connector because I have found on-line references to some of this info and in some cases the pin numbers differ. Your mileage may vary. MOUSE INFO As for the mouse, you will find the pinouts below and the signals. Please note that the pin numbers may not be the official DEC numbers. Here again, I have seen on-line references to some of this info and the pin numbers differ. Looking into the plug coming from the mouse: 5 6 7 o o o 4 o === o 1 o o 3 2 1 - -12v 2 - Data to mouse 3 - Ground 4 - Data from mouse 5 - +5v 6 - nc 7 - nc And looking at the socket on a machine or end of the 17-02640-01 cable: 7 6 5 o o o 1 o === o 4 o o 2 3 Pin 1 to pin 14 of the 15 pin D connector on cable 17-02640-01 2 to pin 6 ... 3 to pins 8, 9, & 15 ... 4 to pin 7 ... 5 to pin 13 ... 6 nc 7 nc

The act specifically says the security measures *shall not* prevent a legal owner from making a personal copy (presumably for backup perposes,etc..). If you can make a backup, you can trade it, etc, just like it is happening now... The second good reason it'll never work is they can't possibly enforce it. You can't subject other countries to US rules policies, and the act doesn't have any provision for open source or freeware, or PD goodies. The US nor any other country can effectively poliece/control the internet. Thirdly, you can't use a hardware decryption because there is no feasable way of that method working on all available platforms (and imagine the US saying to companies that they can't make such and such a product unless they install "our pre-approved security gizmo"), so you would have to use software.. There's no way a software encryption/decryption would work because you could not possibly keep the code from leaking out or being reverse engineered. Lastly (at least how I see it) the act would invariably violate freedom of speach by dictating how and where we could express information. -Linc.

The Smalltalk-80 System also used an interpreter, called the bytecode interpreter, and it was in fact common to take an application compiled on, say, a Xerox Dorado and run it on a Xerox Magnolia, or even a Tektronix box. I've seen references recently to an Alto version of Smalltalk-80 2.2, so the apps crafted at XSIS (Xerox Special Information Systems) like The Analyst(tm), might have been worked out on Altos then run at the The Company on Magnolias. -dq -- -Douglas Hurst Quebbeman (dougq(a)iglou.com) [Call me "Doug"] "The large print giveth, and the small print taketh away." -Tom Waits

Tony replied: > What is this link connected to? What does it reconnect? Ok -- I have yet another version of the schematic here, and it agrees with the first -- L1 for 1K and L2 for 2K but does NOT specify what this means in terms of the actual number of RAM ICs onboard. >From looking at the schematic from the ZX-TEAM web site, I can't see how either jumper would affect a two-chip configuration. L1 ties the single RAM chip's A10 to +5V, while L2 ties the single chip's A10 to the A10 line on the system bus. Can you make any sense out of this, or is it necessary to be Clive Sinclair in order to understand it? As mentioned in a previous post, the 2-RAM-chip ZX81 PCBs I have at hand have NEITHER L1 or L2 installed. I would consider experimentally changing the links L1 and L2 and seeing if this made a difference in the amount of RAM present, except that we're talking about +5V and I don't want to toast any ICs, even common ones, if I can avoid it. Any insight you can provide will be helpful. Glen 0/0

HPIB programming assistance

by steven_j_robertson＠hotmail.com

Hey guys, I am working on a project to breath life back into some old hardware. I order to do so, I need some documentation / assistance in writing low-level routines to talk to various HPIB devices. Specifically: I would like to talk to a HP 7978 tape drive, a CS80 compatible tape drive, or a common HPIB disk drive. I don't need help with HPIB protocol, I need to know the sequence of commands (sent across the bus) to move data into and out of those devices. I would expect to find this information in the programming manuals for those devices but so far, have been unable to locate the docs. If anyone can provide documentation for any of those devices or has experience programming them, I'd appreciate the assistance. Thanks, SteveRob _________________________________________________________________ Chat with friends online, try MSN Messenger: http://messenger.msn.com

5.25" floppy model numbers

Somebody recently posted a fairly comprehensive list of floppy drive model #s with their capacities & base specs. I'd like to grab a few not-1.2M drives before we scrap them, but I've misplaced the list. Would whoever it was be willing to repost? Thanks Doc

More Museum Finds and Help with Disk Needed

by jrkeys＠concentric.net

Well today I went down to one of the warehouses to look around for some items I needed (didn't find them) and found the following items: 1. A box marked CP/M 2.2 for Commodore 64 in it was a manual and a large black cartridge ( it has a Z80 microprocessor in it). I'm missing the CP/M disk which contains both the operating system and some utility programs. If anyone has a copy email me off list. THANKS in advance. 2. A green and off white plastic computer called a IQ 8300 with green rubber keys. It has a POWER 3000 32K Ram black module about the size of a Sinclair 1015 module. I have no Doc's or box for it and it's missing the power supply as well. With have to do a google on this one, if anyone has one or knows anything it let me know. 3. A Panasonic Personal Computer 32K memory model JR-200U. It's light brown and silver in color with dark gray soft rubber keys and some dark blue rubber keys also. It has a built in power supply with the cord coming out the back. It also has the RF unit with so I will test it out tonight. 4. A Sun type 5 kb missing four key caps. 5. Two HP model 9130A floppy disk drives. 6. hp 86 with 82936A rom drawer, 82937A HP-1B interface module,82900A CP/M system module, and a 82909A 128K memory module. 7. hp 97 calculator missing adapter and battery. All in all I had a ball opening boxes that have been packed for almost 6 years now while I was up North.

TEK4014 repair info requested.

by jos.mar＠bluewin.ch

The tread about storage tube terminals reminded me that my Tek4014 is in need of repair... 1) Is it normal that it takes up to 10 minutes to warm up ? It takes that long on my machine before the clear button actually clears the screen. 2) and the real problem : The cursor, existing of a 8x8 dotgrid, often collapses horizontally, i.e. it becomes (much) smaller. This is, due to the storage tube technology, repeated in all characters you then type in. Any pointers as to where I should start ? Jos .

Spam from _sring@uslink.net?

by Sanity_not_vanity＠hotmail.com

Hey, been asked to sort out my folks laptop, so I know nothing of its past etc. I noted your thread and thought this maybe interesting, Their email address keeps getting mail from the "mail demon" notifying them that their mail (that they did not send) was not delivered to the address because it contains something that could be a virus. The mail does point out that the virus attached is called "sm3song.mp3.scr", but the fun doesn't stop there, however easy it may seem from this point doesn't cut it. As I said they get dozens of these mail, and each one says a different name; Humour.mp3.scr, hamster.mp3.scr, sm3song.mp3.scr... the most frequently used one is sm3song.mp3.scr. The email account, by the way they use outlook express :-(, is set up for two different email accounts, the one a simple POP3 account through freeserve, and the other (that I don't understand) through something called freezone, where their website for my mums business is hosted, and also works as a server for her mail. Going back to the mail demon messages; they only represent addresses (from her contact list) who have sent her mail through the freezone account that she has not yet replied to. If any of this seems to be familiar to anyone please email me at Sanity_not_vanity(a)hotmail.com I thought maybe the virus is on the freezone server as apposed to the laptop, also note, the virus does not seem to be doing anything destructive, nor does it show when I do a complete scan of the hard drives using the latest versions of PC cillin antivirus.

UNIBUS Mystery Board ID

by lists＠subatomix.com

This hex-width board was found sitting in a UNIBUS backplane. It looks like it may have more than two PCB layers. The metal handle, where the board number is usually stamped, is unmarked; no board number is stamped there. On the front side, top left, is "AD413A MADE IN USA". The top middle had the "200415-03" handwritten on it, but that has been crossed out by a marker, and "200850-02" appears beneath it. The top right has "S/N 5781" handwritten. There are two 50-pin BERG (maybe formatted Pertec) connectors at the front top. On the back of the board, at the top right, is "MRX42 200255-02", machine printed. A little to the left of that is "3183", handwritten. Google has returned nothing. What have I here? -- Jeffrey Sharp The email address lists(a)subatomix.com is for mailing list traffic.

More VMS

by alan.pearson＠cramer.com

As an aside to the current VMS discussion, does anyone know of an equivalent to the Unix "su -" command for VMS? Basically I'd like to be able to use my "normal" AL account for messing about with but occasionally "su" to SYSTEM to get at a protected file or directory. All the FAQs and manual pages I've come across so far point to SPAWNing a new process and then changing the privileges (eg SET PROC/PRIV=SYSPRV), which defeats the object of the exercise since the "AL" account needs system privileges in order to do the SET PROC/PRIV in the first place :-) At the moment I'm using an ST running UNITERM hooked up to a 3100/30's console port so I'm stuck with just the one login session at a time - occasionally I'd like to be able to flip over to SYSTEM without having to mess about with logging out of AL and into SYSTEM and back :-) Any ideas? Cheers Al.

UCSD P-System & "compile once, run anywhere"

From: Eric J. Korpela <korpela(a)ssl.berkeley.edu> >It also depended upon how the virtual machine was implemented. The >Apple Pascal virtual machine was horrible.

I'd agree though it made it possible to run the sources on a Z80 S100 crate, a trs-80 and an apple and moveing the code around was done with a simple serial utility (lack of common disk format!). The best platform other than the microengine was PDP-11, The z80 wasn't too bad (comparable to Cbasic). Allison

Apple IIe w/ALS Z-card

by pat＠cart-server.purdueriots.com

I picked up one of these today from Purdue Salvage. Anyone have any useful software for it? I might be willing to sell it if anyone's interested. I was kinda disappointed... out of 6 or so Apple IIe's they got in, not one had an expansion card besides DiskII, the Z-Card and a printer interface. Still looking for a SuperSerial card so I can copy data to it (and a copy of Disk Tools on 5-1/5" floppies for it) -- Pat

I'm a ZX81 fan because (as another listmember quipped) it's the most minimalistic *full system* ever. But Sinclair's products were all plagued with cheap parts. There are plenty of stories of how Sinclair would change designs in the middle of a production run because they had found a part that was ten cents cheaper, or they'd found a way to keep the circuit intact while eliminating a couple of five-cent caps.

Burroughs Tape drive on ebay

by Innfogra＠aol.com

Heads up Minnesota or those in the area. Found this filed under photo stock. Not only was it miss categorized but the owner has no idea what it is. Four days to go. It looks like a Portable R to R tape drive for an early Burroughs Computerized Accounting Machines. (Looking at the styling) http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=1341100641 A great collectable but it is heavy. If anyone contacts the owner I would be interested in what interface it has in it? I am not at all interested in the drive but I know it is fairly rare now. Paxton Astoria, OR

Yes. NeXTstep does not have the software drivers to build new raw DOS file systems. Except on floppy disks, where the file structure is much simpler. What there is lives in /usr/filesystems. I suppose that nowadays you could attach your SCSI MO drive to a Linux system and build a DOS file system there. There is a software package "dosfstools". Reading through again, if you want to reformat a MO disk from DOS to NeXT, what I remember as the magic recipe is first to format it as a Macintosh file system. Then you can make a NeXT-format disk out of it. carl

Turbo BASIC (was Re: QL (was: ZX-81 Question))

by ajp166＠bellatlantic.net

I happen to use MS QB4.5/dos at work for test systems. This version supports all the high level structures and variable scopes that HLL like Pascal or C would. It's NOT a weak light weight BASIC. It does produce fast, low ram load executeables (.exe) for dos environments and has proven very robust and easy to use. My beef with BASIC is especially the older versions with GOTO laden code can easily be a bowl of long pasta to decode. However, I've seen people do same with Fortran, ALGOL, Pascal and even C.

OpenVMS Alpha, yes from V1.5-1H1 onwards (i.e. almost any version you happen to have). Ultrix never ran on these birds. Digital Unix (now known as Tru64 but probably in the middle of another name transition) did support them but I have a feeling that support was dropped in the most recent version. And in this case they actually pulled the support code, so it absolutely will not work. >Also, I didn't get a keyboard with >it and didn't see one there. What >kind of keyboard does it use, and can I >use a serial terminal instead? I guess a PC keyboard (LK451 or such???) but I don't have any docs to hand. Almost all of these boxes will work with a serial console ... plug in and type set console serial (otherwise it switches to the graphical console partway through the boot and if all you have is serial yo uthink it's died on you!!)

VCF Gazette Volume 1 Issue 1

by vcf＠vintage.org

VCF Gazette Volume 1, Issue 1 A Newsletter for the Vintage Computer Festival March 13, 2002 Hello Vintage Computer Fans! Welcome to the first issue of what is guaranteed to be an irregularly published newsletter to keep you up to date on the latest events and happenings of the Vintage Computer Festival. There is a lot going on this year. We have two major events, VCF Europa 3.0 and VCF 5.0, and an Open House at our Oakland, California, facility. VCF Europa 3.0 -------------- The third annual Vintage Computer Festival Europa is being held April 27th and 28th in Munich, Germany. If you have a chance to be in Munich during the last weekend of April, you should certainly attend. You'll get a taste of the vibrant computer industry and the varied computers that were produced in Europe from over ten years ago and beyond. For more information on VCF Europa 3.0, visit: http://www.vintage.org/2002/europa/ --or-- http://www.vcfe.de/ VCF 5.0 ------- As you may well be aware, VCF 5.0, originally scheduled for September 15th and 16th, was cancelled due to the tragic events that occured on September 11, 2001. The necessity for the cancellation slowly became evident as events transpired over the course of the three days following September 11th. At least three speakers were not going to be able to attend due to the grounding of all U.S. air traffic. It was uncertain whether more attacks would come. In hindsight, cancelling VCF 5.0 was still the right decision to make, as it was uncertain whether anyone would even want to come to such an event in the wake of the tragedy. A statement was posted to the VCF 5.0 website on Thursday, September 13, informing of the cancellation, and a message was sent to the VCF mailing list. We appreciate the understanding we received. Now that things have thankfully returned to normal for the most part, it is time to reschedule VCF 5.0 for 2002. Planning is underway to hold VCF 5.0 sometime in September. Negotiations are underway for securing a venue in Santa Clara (our first choice) or San Jose (our backup choice). VCF 5.0 will be more exciting than ever this year. We plan to offer more great speakers and many excellent exhibits, but we also plan to expand attendee participation by adding retro-programming contests and other events. Of course we will still have the Nerd Trivia Challenge to vex even the most ardent vintage computing nerd. More details to come! VCF 5.0 will also be part of a larger smorgasbord of events which is tentatively being dubbed "GeekWeek". The VCF will partner with the California Extreme Classic Arcade Show, the Xtreme Games Developers Conference, the first San Francisco International Conference of Hackers, an Atari 30-Year Anniversary Party, and several other accompanying events including LANtrocity and Super Auctions (coin- operated amusement auctions). This exciting combination of events will become a yearly mecca for geeks from all over the world to come together and celebrate the joys of geekdom! Information for each event can be found at the following URLs: Vintage Computer Festival 5.0 http://www.vintage.org/2002/main/ California Extreme http://www.caextreme.org/ Xtreme Games Developers Conference http://www.xgdc.com/ San Francisco International Conference of Hackers http://www.gism.net/sfich/ Atari 30-Year Anniversary Party (Atari Historical Society) http://www.atari-history.com/ LANtrocity http://www.lantrocity.com/ Super Auctions http://www.superauctions.com/ VCF East 2.0 ------------ Last year's first Vintage Computer Festival East, held in Marlborough, Massachusetts, in July of 2001, was every bit as fun and exciting as the main VCF. Five speakers, including Eldon Hall, designer of the Apollo Guidance Computer, and eleven exhibitors, including the Retro- Computing Society of Rhode Island who brought along a PDP-12 running Spacewar!, provided a vintage computing retrospective for over 80 attendees. The next VCF East is being planned for Spring of 2003. We will begin booking speakers, exhibits and vendors in the fall of this year. VCF Open House at the ACCRC --------------------------- As of Fall of 2001, the Vintage Computer Festival Archive has found a happy new home at the Alameda County Computer Resource Center. The ACCRC is an organization that accepts donations of old computers and electronics, refurbishes the working computers to be donated back to schools and charities, and recycles the rest. Nothing at the ACCRC is thrown out. Everything gets recycled! ACCRC computers are located on every continent on Earth including Antarctica. The VCF is busily sorting, organizing and cataloguing the VCF Archive at the ACCRC. Shelving is being assembled, walls are being built, and floors are being swept in preparation for the first VCF Open House. The VCF and the ACCRC will welcome the general public to come in and see how we operate. There will be plenty of activities, tasty things to munch on, and tours of the VCF Archive and the ACCRC operations and pet programs (including the ACCRC Beowulf Cluster and KOOX internet radio station). The VCF is also in the process of setting up a computer museum at the ACCRC and building facilities for our documentation and software archive library so that it can finally be offered for use by the general public. We're hoping to finish the remodeling effort within a few weeks but we're still searching for needed materials. We'd like to find recycled computer flooring to improve the floor in the area where we are setting up the library. Might you know of where we can get some? If so, please let us know by sending an e-mail message to <vcf(a)vintage.org>. Any flooring donated will qualify as a tax deductible charitable donation to the ACCRC. Once we have the archive organized and the library completed, we'll announce the dates for what will become the first annual VCF Open House. We're very excited at the prospect of finally having a public venue to share the VCF Archive on a year-round basis. For more information on the Alameda County Computer Resource Center, please visit their website: http://www.accrc.org/ To listen to KOOX internet radio, visit their Screaming Streaming Audio website: http://www.koox.net/ If you have computer flooring to donate, or know of someone who does, please contact us at <vcf(a)vintage.org>. VCF on MediaTelevision ---------------------- MediaTelevision, a Canadian program that "looks inside and behind the media process", will be airing this week a segment that they produced on the VCF. Watch for it on a station that airs MediaTelevision's program. For information regarding MediaTelevision's segment on the VCF, visit: http://www.mediatv.net/ VintageTech ----------- The Vintage Computer Festival is proud to announce a new off-shoot for business and industry. VintageTech provides services such as patent litigation support and prior art searches, consulting and props for the film and photography industry, data and media conversion, vintage computer appraisals and sales brokering, and general computer history consulting. To inquire about VintageTech services or for more information, visit VintageTech today: http://wwww.vintagetech.com/ Classic Tech Eletter -------------------- Michael Nadeau, long-time computer industry journalist and former editor of Byte magazine, has launched a new newsletter that caters to the vintage computing audience. The Classic Tech Eletter is a monthly newsletter delivered right to your e-mail box. Each issue contains news and stories concerning happenings in the world of old computers and the folks who collect them. Subscribe to the Classic Tech Eletter and see back issues at: http://www.classictechpub.com/ ---------------------------------------------------------------------- That wraps it up for this first issue of the VCF Gazette! Until next time... Best regards, Sellam Ismail Producer Vintage Computer Festival http://www.vintage.org/ The Vintage Computer Festival is a celebration of computers and their history. The VCF Gazette goes out to anyone who subscribed to the VCF mailing list, and is intended to keep those interested in the VCF informed of the latest VCF events and happenings. The VCF Gazette is guaranteed to be published in a somewhat irregular manner, though we will try to maintain a quarterly schedule. If you would like to be removed from the VCF mailing list, and therefore not receive any more issues of the VCF Gazette, visit the following web page: http://www.vintage.org/remove.php ;) -- Sellam Ismail Vintage Computer Festival ------------------------------------------------------------------------------ International Man of Intrigue and Danger http://www.vintage.org * Old computing resources for business and academia at www.VintageTech.com *

Last I heard, NetBSD didn't support TurboChannel -- or was that Linux, but it's been a while. Ultrix? No, but you can run Digital Unix on it, or OSF/1, or whatever its name is today. Of course, I could be mistaken, but I believe VMS is supposed to run very well on these. In fact, if I had one, that's what I'd do. > keyboard with > it and didn't see one there.

It will either be a "normal" peesee keyboard plug, (wouldn't use anything but a real DEC keyboard, though), or it will be a "normal" DEC keyboard (like for the vt320, etc). Being an Alpha, it's more likely the former, but that's an early Alpha, so check the shape of the plug before you plug the keyboard in ;) ... and of course you can use a serial terminal. (Might, or might not require removing the framebuffer -- it did on some older VAXen.) Try just plugging the terminal into what looks like the first serial port, and you'll probably be pleasantly surprised.

info needed: Shinwa printer

by rigdonj＠cfl.rr.com

Does have any info on this printer? It looks like this <http://www.morgancomputers.co.uk/bargain-products/bargain-product-info.ASP?…>. I picked one up today. This one is marked "Terminal Printer" and model MH-4015+ but the FFC ID number says that it's made by Shinwa and it lappears to be the same as the CPB-136. It's a dot matrix printer and it has SIX printheads in it! Joe

More VMS

by ajp166＠bellatlantic.net

Yes, If you use a terminal like VT330, 340or later there is what VMS calls multisessions. Some fo the LAT servers also support this with more common VT220s or VT320s. I was added late in VMS 4.mumble and later versions. This is not decwindows which is GUI based. What multisession allows is several virtual terminals over several virtual circuits using one terminal and physical circuit. I use it alot.
