Another VCF is upon us ... VCF PNW 2019 takes place March 23rd and 24th at Living Computers:Museum+Labs in Seattle. We have 30 exhibits (up from 20 last year) and six speakers, including Joe Decuir, IEEE Fellow. Our exhibits include: Josh Dersch with Three Rivers PERQ workstations David Cooper with a VAX cluster Vince Slyngstad demonstrating PDP-8 reapirs Foone Turing with his collection of floppy and optical disks Joerg Hoppe with BlinkenBone and UniBone (w/ Josh) Oscar Vermuelen with his replicas of the PDP-8, 11, and LGP-30 Ian Finder, over-achieving with two exhibits and helping on third Alan Perry with his SPARC clones Some rif-raff with their 8 bit home machines. ;-0 Admission is free once you pay to get into the museum. And of course the museum is worth checking out even without us, but we are going to make it that much better. We'll have a consignment room if you want to do some treasure hunting. (If you are looking to sell some treasure, that works too - you don't have to participate in the event to use the consignment room.) Full details can be found at http://vcfed.org/vcf-pnw/ . Or email me directly if you have questions. -Mike

1983 UBC PDP-11 Unix tools distribution

by aek＠bitsavers.org

Today's tape recovery gem. UBC's PDP-11 UNIX tools distribution ca. 1983 which includes UBC BASIC and their RT-11 emulation. It has a couple of bad blocks, but I couldn't find another copy of this anywhere. http://bitsavers.org/bits/UBC/ If anyone has a complete copy, it would be good to replace it, but most is better than none of it.

KansasFest 2019

by a2history＠gmail.com

For your interest: MARCH 8, 2019 ? KansasFest 2019, the 31st annual Apple II convention, is scheduled for July 16 ? 21 in Kansas City, Missouri. Mark Pelczarski of Penguin Software, well-known for numerous graphics utilities, books, and games, will join us with a keynote presentation to celebrate the Apple II. Pelczarski began publishing graphics-related Apple II software in 1978 while in his early 20?s under the brands Penguin Software and Polarware <http://graphicsmagician.com/polarware/index.htm>. He is an entrepreneur, author, programmer, consultant, and professional educator. Mark is well known for the Graphics Magician <http://graphicsmagician.com/polarware/graphics.htm> software, a toolkit for creating graphics that includes over 50 major software publishers as customers including Random House, Sierra Online, Spinnaker, and Mattel. He wrote monthly columns for Softalk and the book Graphically Speaking. Besides pioneering computer graphics, Polarware published numerous games including Transylvania <http://graphicsmagician.com/polarware/adventures.htm>, The Coveted Mirror <http://graphicsmagician.com/polarware/adventures.htm>, and Spy?s Demise <http://graphicsmagician.com/polarware/arcade.htm>. After leaving Polarware in 1987, Mark turned his attention to computer music and to online courses. Mark once said ?I like to make computers do things,? <https://www.chicagotribune.com/news/ct-xpm-1985-03-01-8501120306-story.html> so he?ll surely fit in at KansasFest. KansasFest is an annual convention offering Apple II users and retrocomputing enthusiasts the opportunity to engage in beginner and technical sessions, programming contests, exhibition halls, and camaraderie. KansasFest was originally hosted by Resource Central and has been brought to you by the KFest committee since 1995. Any and all Apple II users, fans, and friends are invited to attend this year's event. Registration details will be announced on the KansasFest Web site, and registration will open on March 31.

Unix tools, Bill Webb, UBC, TRIUMF

by tshoppa＠wmata.com

I recovered several pieces of Unix media ? all of which I think made it into TUHS/PUPS collection - at UBC in the mid-1990?s while I was working at TRIUMF. Those Unix disks and tapes came from a SERF sale (Surplus Equipment Recycling Facility) on UBC main campus, not from TRIUMF. Bill Webb was a common thread for Unix use in the biology department at UBC. TRIUMF extensively used Data General Nova, then Eclipse (both 16 and 32 bit), computers from opening through the 1990?s for both cyclotron control systems and data acquisition for experiments. They also had a fair number of PDP-11?s and VAXen running RSX-11, RT-11, and VMS. I myself had an Alpha workstation on my desk for the two users I was at TRIUMF. One of my favorite connections between TRIUMF and UBC, was the underground pneumatic tube used to rapidly carry short lived isotopes produced in the cyclotron to the main campus for biology and medical uses. It should not come as a surprise to anyone that I still work in moving things and people through underground tunnels ? Tim N3QE

IBM 3174 C 6.4 Microcode Disks?

by Kevin＠RawFedDogs.net

Classic Computer Fans, I posted this to the IBM-Legacy-Hercules mailing list. I just realized it probably wouldn't hurt to post it here too. I'm finally in possession of a box that hopefully is capable or can be made capable of connecting a real terminal to Hercules. It's a 3174 11L. It was retired last year where I work. I finally got the okay to save it from being sent to a scrapper. I love the build quality of older IBM gear, except when I'm trying to move such gear. Between the 3174 and a 9406-520 I also acquired, I pulled or strained something in my left arm moving them into place. It's currently wired to run on 220v. I think I've seen mentioned somewhere that it can be changed to run on 110v. If that's the case, does anyone have a pointer to documentation on what's involved? It has dual floppy drives. At least one drive is a 2.4MB drive. But, all the microcode disks I have are at level B 4.6. Does anyone know where I can get a set of C 6.4 control and control extension disks. From what I've heard those are what's needed to enable an attached terminal to connect to other systems via telnet. It has a token ring card. I will probably be able to get the MAU it was connected to, and possibly the router that acted as a token ring to Ethernet bridge. I'm not sure how much memory it has. Does anyone have any tips on determining the amount of memory it has, and/or identifying its boards? These are the numbers on its boards: 9210 9351 9052 z2 9053 9501 Plus the boards for coax connections. -- Kevin http://www.RawFedDogs.net http://www.Lassie.xyz http://www.WacoAgilityGroup.org Bruceville, TX What's the definition of a legacy system?

Need some PDP-11 paper tapes

by rich＠ourowndomain.com

I just picked up a Remex paper tape reader from eBay and will be interfacing it to my PiDP-11/Simh PDP-11 simulator shortly. I've been looking for an affordable punch, but haven't found one yet. In the meantime, does anyone know where I could get paper tapes with the absolute loader and standalone basic? I don't need originals, so if anyone has a punch and is willing to punch them for me, that would be great! I'd be happy to pay whatever is reasonable. If you have any other PDP-11 tapes too, that would be helpful. Thanks. Rich

PDP-11/60 manuals needed

by jnc＠mercury.lcs.mit.edu

> From: Jay Jaeger > I have EK-11060-OP-003: "PDP-11/60 installation and operation manual" > and an update EK-11060-OP-C1. Yeah, that's the one I referred to as "the general -11/60 manual"; generally, there's one such for all the -11 models, but the exact name varies from model to model (unlike, say, the CPU tech manuals, the name for which is pretty predictable). > let me know and I will scan it in and stick it on my Google drive in a > day or two or three That would be great; thanks very much! No rush at all... > I also have a spare processor handbook, EB-06498-20/77 We do have that one, thanks. BTW, looking a little more closely at the cabinet/power-supply manual (pg. 1-7), the KD11-K TM might _only_ be available on fiche. If so, that'll be the first time I've ever seen that. Oddly enough, further down the page, the FP11-E TM seems to be available in printed form (EK-FP11E-TM). > From: Ethan Dicks <ethan.dicks at gmail.com> > I've seen Tech Manuals printed as 2-up on C-sized paper Yeah, generally things from the -11/20 era are like that (e.g. the RK11-C manual). Nothing later than that that I've ever seen, though. >>> I have the two BA11 cabinets for an 11/60, the PSUs, and the front >>> panel (I'm missing the rack). > "the rack" is just the outer box with rails (not an H960 - whatever the > designation is for the odd 11/60 cabinet). I think it's the H9500 low-boy corporate cabinet, per Chapter 5 in the cabinet/power manual. > The backplanes are in the BA11s.

You seem to have most of the crucial bits, although you might be missing the power harness. Do you have the optional WCS module (M7870)? There are also ROM modules, and a diagnostic module, that can go in that slot - only one of the three at a time, though. Noel

My route will be Santa Barbara, Las Vegas, north to I-80, and I-80 to the Chicago area. After that, I'll be headed to Pittsburgh, PA and it can be dropped off along the way.

Data Systems Design DSD-4140 microcode PROMs

by jzatar2＠illinois.edu

Hello Everyone, We found a PDP-11 QBUS card cage with a KDF11 and some other cards (RAM, ROM, some basic peripherals) which included a DSD-4140 card. Unfortunately, the DSD-4140 is missing one of it's microcode PROMs for some reason. Does anyone else have one of these cards? It'd be really helpful if we could get some dumps of the 4 microcode PROMs so we can compare what we have and look into replacing what we don't have with an adapted modern part. (and if anyone goes to the trouble to read the 4 microcode PROMs, there's also an 82S137 that deserves to be dumped). Here's a picture of the card in question: https://i.imgur.com/tzYjPYF.jpg Regards, Joe Zatarski

OK, thanks, that's great. Now I won't have to bother tracing things out if I decide to go that route. Didn't realize there was a printset for the KA650, but I guess I didn't even bother to check.

KA650 VAX memory error

by jzatar2＠illinois.edu

Hello Everyone, I've got a KA650 with a MS650-AA 8MB memory module. When we initially started messing with this VAX, it was giving a memory error. We were able to track down first the bad bank, and later the individual bad ZIP RAMs with the help of my logic analyzer. For now, I kludged an SOJ DRAM in there that seems to be working without issue. The machine no longer gives memory errors during POST, but if you run one of the more thorough memory tests like #48 (MEM_Addr_shrts), it fails. My initial thought was that this RAM test checks for shorted address lines, which would cause writing to one location to change another location perhaps. However, I haven't been able to replicate the error with DEPOSITs and EXAMINEs on the console. Without having to disassemble the VAX ROM, does anybody know what this test does? Once I know what I'm looking for, I can probably convince the logic analyzer to see the error with some fancy triggering, and get this board 100% fixed before I order some ZIP DRAMs. On a somewhat related note, I don't suppose anybody knows or has documentation on the pinout of the C/D interconnect on these RAM boards? The pinout for the ribbon cable is in the manual, but the C/D interconnect doesn't seem to be documented in any of the manuals that are online. With the price of MS650's these days, it seems like the cheaper route (albeit more work) is to build a new RAM board rather than buy one (especially if a single 64MB board could be made). I suspect it's not too complex anyway, and it can probably mostly be traced out, and the rest inferred and then verified with a logic analyzer. Thanks, Joe Zatarski

HP logic analyzer QFP132 interposer and DSD-4140 microcode ROMs

by jzatar2＠illinois.edu

Hello everyone, I've got two unrelated things I'm looking for: The first is an HP logic analyzer interposer for the emulation adapter for an MC68332. This would have a PGA socket on it, and sort of a reverse socket for the QFP132 package (attaches to a chip from the top, to interface to a chip soldered onto a board). I believe the part number would be HP E3417A. I already have the QFP160 adapter, but the chip I want to interface to is a QFP132. This adapter supposedly exists, but I've had no luck trying to find it through the usual channels. The second that I'm looking for, is if there's someone out there that owns and can dump the microcode ROMs from a DSD-4140 QBUS floppy controller. We've got a card here that's missing one of the ROMs, and we're also not sure if the ROMs are mixed up, so a dump of all 4 ROMs would be appreciated. They are 82S181, but they should read in any EPROM burner with a breadboard and some wiring to adapt the pinout. Burning them is another story, but we'll worry about that later... Here's a picture of the card in question: https://i.imgur.com/tzYjPYF.jpg And if anyone has one of these and is kind enough to dump it for us, there's also an 82S137 on the card that probably deserves a dump as well. Thanks, Joe Zatarski

V6 cc needs hash before whitespace before first include?

by fritzm＠fritzm.org

So, I've been having some fun playing around with V6 Unix on my 11/45 a bit after that last repair. I've just been tripped up for a little over the fact that the C compiler barfs if there is whitespace/comentary before the first #include; the workaround seems to be to add a lone '#' at the beginning of the file. It took me a while to notice that this was done, for example, in all of the device driver sources. I found this curious. Anybody know what the story is there? --FritzM.

by jnc＠mercury.lcs.mit.edu

> From: Phil Budne > I'm betting it was a speedup to not fork/exec another process if it was > going to be a null transform! It's worse than that! In vanilla V6, the pre-processor is built into 'cc', not a separate command. Here's the relevant code (from expand()): if (getc(ibuf1) != '#') { close(ibuf1[0]); return(file); } The code to implement the directives is, ah, entertaining. Noel

PDP-11/60 manuals needed

by jnc＠mercury.lcs.mit.edu

Hi, does anyone have any PDP-11/60 manuals? I went to do articles on the -11/60 and its CPU (KD11-K), but there isn't much online. Bitsavers has EK-KD11K-TD-PRE, but it only covers the maintenance features, not the whole CPU; there is a tech manual - KD11K-TM-001 (I have it in fiche, but my fiche reader has a burned out bulb which I have not yet been able to replace, so it doesn't do me much good). There is a user manual for the FP11-E, which has a certain amount of useful details, but it refers to the technical manual, which is not there. And there's EK-11060-SV-01, which covers the cabinet and power supply. So if anyone has the general -11/60 manual, or the KD11-K tech manual, those would be super useful. The FP11-E tech manual would be nice to have, but isn't as important as the others. Thanks (I hope!)! Noel

HP 85 tapes

by Martin.Hepperle＠MH-AeroTools.de

Christian, there is the document "9915-TapeDuplicationAndEPROMProgrammingSoftware-09915-10011-46pages-Jul83.p df" on the HP-.Museum web site. I think the associated software is not available, but it also uses the TAPDUP binary (pg. 1-2) and the same IMAGE program. The binary itself was part of this and is not documented (it was considered part of the whole package). What is available via M. Craggs web site are the files from a "Hybrid ROM Creation Pak", which includes TAPDUP. The IMAGE program (pg 2-2) contained there is probably similar or the same. The Master/Slave programs and some more are not in this package. >From the "Hybrid ROM Creation Pak" AUXROM.ASM AUXROM.BAS AUXSHELL.BAS CREATEROM.BAS DATAIO-19.BAS DATAIO-29A.BAS EPROM2.BAS IMAGE.BAS --- 20 !

PDP-11/60 manuals needed

by jnc＠mercury.lcs.mit.edu

> From: Bill Degnan > The 11/60 handbook doesn't have that kind of designation. It's EB06498 Yeah, that's the processor handbook, which is the paperback-sized thing which is mostly a programmer's reference; I've got that, its the 8-1/2x11 sized things I'm after. > From: Ethan Dicks > Is it by any chance EK-KD11K-TM-001? > That part number is for a print-set Uhh, no. Looking at the fiche version, EP-KD11K-TM-001, it has lots and lots of text blocks (which I can't read without a fiche reader, of course). We do seem to have the print sets: MP00166 11/60 System (chassis, power contoller, etc) MP00409 KD11-K CPU MP00500 WCS (M7870) MP00429 FP11-E but I'm not desperate enough to learn the -11/60 by looking at them! > I'm following the discussion because I have the two BA11 cabinets for > an 11/60, the PSUs, and the front panel (I'm missing the rack). And by 'the rack', I'm guessing that includes the backplane? Looking through the prints, I think I didn't see details on it (alas). Noel

Another DEC UNIBUS signal adapter: UniProbe

by j_hoppe＠t-online.de

Hi, most people dealing seriously with older PDP-11s have found means to monitor the UNIBUS traffic. My latest approach is www.retrocmp.com/tools/uniprobe UniProbe is a M9302 terminator, a LED display, a probe for logic analyzer. It can be mounted in Standard or Modified UNIBUS sockets. I'm ordering a batch of PCBs in a few days and will show this and other stuff (UniBone, BlinkenBone) at VCFPNW in Seattle. https://vcfed.org/wp/festivals/vintage-computer-festival-pacific-northwest/ best regards, Joerg

HP 85 tapes

by Martin.Hepperle＠MH-AeroTools.de

Christian, the TAPDUP binary and associated utility programs in BASIC was used to create EPROMs with programs and data for the 9915 Series-80 box. It can be used to read the directory record and then to read tokenized PROGrams as data on a file-record base - not at low record level. The package also contains programs to massage the PROG data into BASIC DATA statements for creating EPROM burner files. You could use it to read the tape directory and individual PROG files but right now I am not aware of a program which would write this data back to a tape. You would open the directory, look up a file and then OPEN IMAGE it. Next you would READ RECORD IMAGE$ the program record by record. In the end you have not gained much compared to the simple COPY statement. Except for the copy of the directory with attributes and security flags. Alternative: There are also READSECTOR binary programs for reading raw 256 byte records/sectors from disks. They also work on the tape ":T" but seem to start their record count after the directory records. On disks, record 0 is the first real sector. So, to get the complete binary content one could use C$=CATALOG$ from TAPDUP to read the directory record READSECTOR N,R$,D from to read the subsequent raw "data" records. Here are my notes on some of the functions in this binary program: The TAPDUP Binary (Notes by M. Hepperle) This binary contains functions to read tapes (HP-85, 9915) at low level. It does not handle disks. The program was part of the "Tape Duplication and EPROM Programming Pack" (09915-10010). As the original software was not available the binary was re-assembled from an assembler source file. This source file was obviously created by disassembling the original binary. It was found at M. Craggs web site: http://www.biblewitness.org/technical/HP_Series-80/HP-85/ASSM . Martin Craggs home-made disassembler produced many unnecessary DRP and ARP statements, which could be cleaned up to improve readbility. Functions in the TAPDUP binary: C$=CATALOG$ Return the directory record of the tape in form of a 512 byte buffer (2 records). C$ must be DIMed to at least 512. OPEN IMAGE F$ Find the file F$ and open it for reading. ERRN=67: file not found T=READTYPE Return the file type of the currently opened image (the file image must be opened by a preceding call to OPEN IMAGE) 34 = PROG N$=READNAME$ Return the file name of the currently opened image (the file image must be opened by a preceding call to OPEN IMAGE) R$=READ RECORD IMAGE$ Read the next record of the currently opened file. The record has a length of 256 bytes. Reading can be continued by another READ RECORD IMAGE$ until ERRN=71 indicates a read behind the end of the file. See lines 440 ff in IMAGE program for a typical reading loop. (the file image must be opened by a preceding call to OPEN IMAGE) ERRN=71: end of file reached. CREATE IMAGE S$,I,J,K 3 numeric parameters WRITE IMAGE R$ Write record to (where?) "Error 244: No file open" WRITE CATALOG C$ Writes the catalogue back to disk. C$ must contain a valid catalog structure, otherwise your tape will be unreadable afterwards. READLOGLEN Read the logical record length, which is 256. Another useful function in the Program Development ROM C$=CHECKSUM$(S$) Return the IBM SDLC CRC checksum of the given string (the length of the checksum is two bytes). Example: dumping the tape catalog Each catalog entry is 12 bytes 10 DIM C$[512] 20 C$=CATALOG$ 30 K=1 40 FOR I=1 TO 504 STEP 12 50 FOR J=1 TO 12 60 PRINT C$[K,K]; 70 K=K+1 80 NEXT J 90 PRINT 100 NEXT I 110 PRINT 120 END Tape documentation lifted from Everett Kaser's Series-80 Emulator (I hope Everett won't sue me for this blatant copyright infringement): TAPE LAYOUT ------------------------------------------------------- The HP-85 tape cartridges contained at most 43 files. File 0 was always the TAPE DIRECTORY, and was always 4 records long. Files 1-42 were the user-created files. The tape itself had 2 TRACKS, 0 and 1. There were TWO COPIES of the TAPE DIRECTORY, one in records 0 and 1 of file 0, and a second in records 2 and 3 of file 0. Record 2 was an exact duplicate of record 0, and record 3 was an exact duplicate of record 1. Only one record of the directory could be read into memory at a time, so the system had to keep track of whether the first 1/2 or the second 1/2 of the directory was in memory (or neither). Each DIRECTORY RECORD consisted of 21 12-byte directory entries, which equals 252 bytes. The final 4 bytes of each record as follows: 252 directory segment flag (0 or 1). 253 FILE# of file that wraps from the end of TRACK 0 to the beginning of TRACK 1. 254 (2 bytes) RECORD# of first record of the split file 255 that's on TRACK 1. Each DIRECTORY ENTRY consists of 12 bytes, allocated thusly: BYTES DESCRIPTION ----- --------------------------------------------- 0-5 ASCII FILE NAME, blank filled 6 EXTENDED File Type 7 FILE TYPE 8-9 # RECORDS in the file 10-11 # BYTES in each record The FILE TYPE is thus: BIT DESCRIPTION --- ----------------------------------------------- 0 No directory name listed 1 Soft write protect 2 Extended file type (****) 3 Binary Program (BPGM) 4 Data file (DATA) 5 BASIC Program (PRGM) 6 Empty file (NULL) 7 Next available file The most significant bit of the EXTENDED FILE TYPE byte will signify extended file type as well as BIT 2 of FILE TYPE, but it shouldn't be used, as a bug in the system doesn't clear that bit if you purge the file. The lower seven bits allow the differentiation between various extended file types (****).

HP 85 tapes

by cc＠informatik.uni-stuttgart.de

Hi, what is the recommended way to image HP 85 tape cartridges? The best would be including headers and whatsoever, and to be able to recreate tapes from the images and have a 1:1 duplicate from the original cartridge. I'm almost done with rebelting and imaging our 264x cartridges and would like to continue with the other tapes (85 and 9845). Christian

PDP-11 LDA BFD backend for gnu binutils

by fritzm＠fritzm.org

I've been thinking it might be nice to have an LDA BFD backend for gnu binutils, so gas, ld, objdump etc. could deal with LDA's directly without having to use separate conversion utilities. Before jumping in on that, though, I thought I'd ask here to see if anybody might have already started or done this? I've noticed several of the folks here also have contributions on some of the binutils lists. thanks, --FritzM.

IBM 3174 C 6.4 Microcode Disks?

by seefriek＠gmail.com

re: Cisco and IBM protocols If you're really interested, all of this is exhaustively documented under the umbrella of Cisco's "IBM Feature Set". There's a *lot* here under the hood, but the last time I looked (admittedly, a while) a number of folks had web sites that documented the correct incantations for Hercules and common hardware. You can bridge between TR (and FDDI) and ethernet on a Cisco, generally for non-routable protocols (e.g. NetBIOS); see: 'translational bridging'. If you're trying to get these protocols across an intermediary 'alien' network (like the corp FDDI backbone, or the Internet), there are things like DLSw. If you're trying to get TCP/IP from TR to ethernet and vice versa, routing generally works better/is simpler (IME), but Cisco has all sorts of bizarre encapsulation/translation features for different use cases should you need them. You can also make the router look like an SNA concentrator (PU?). KJ

Compaq 9000 Rack Thumb Screw

by cctalk＠ibm51xx.net

Slightly off topic for list although the rack and equipment are almost 20 years old now.... I got me a hand me down Compaq Proliant StorageWorks UE Rack. Basically it is a rack case that can hold 14 drives. The case is secured to the cabinet with two thumb screws (see attached pictures). These are like standard thumb screws except there is a spring component to them as well (I assume to give wiggle so it is easier to match screw to cage nut). You can see pictures of the screws in this VCF post: www.vcfed.org/forum/showthread.php?68556-Compaq-Rack-Thumb-Screws&p=559354#p ost559354 On my hand me down the one on the left is missing. I have looked and there doesn't seem to be a Compaq part number (I think the screws are press fitted into the metal frame so not really user replaceable). I don't think there is anything special about the screw and I can always use a standard M6 screw for the missing side. However, I'd like to try and match/restore the original. I have tried googling for theses screws but I am not coming up with the right item. I am guessing I am not using the right terms or names for the screws. So does anyone have some broken/parts Compaq rack equipment where I can have the screws? Or can point me to a source online to get a replacement? TIA! -Ali

Anyone have spare DipStik sockets?

by carlclaunch51＠gmail.com

In the early 1970s a socket to hold multiple DIP chips was being sold under the brand name DipStik. Up to six chips were inserted in a trough in the socket, a top screwed on with thumbscrews on the ends. It had solder lugs on the top and bottom for each of the chip pins. We are restoring an old electronic device that was built in part with these, but due to some corrosion we could use replacement DipStik units if anyone has them. Carl

PDP-11 disk image question

by bill.gunshannon＠hotmail.com

So, I used SIMH to do an install of a complete OS on an RA81 disk. I would like to move this to a real disk and try it on a real PDP-11. Is there a way to do this using dd on a BSD machine? I tried but it created a non bootable system. Well, actually, it starts to boot but then fails very early in the startup process. I used "dd if=filename of=raw-device bs=1024". Could it be that the block size needs to be something else? I know that VTServer and PDPGUI can move disk images but it would take a week at 9600 baud and I think very little likelihood of it ever completing successfully. bill

VCF Midwest 14: Date Announcement

by silent700＠gmail.com

Hello everyone - since people have already been asking (we even had someone call the hotel to try to register - that's some refreshing pro-activeness), we can confirm the date of this year's Vintage Computer Festival Midwest will be: September 14-15, 2019 2019 will bring a NEW LOCATION which will be announced in the coming weeks. So don't call the old hotel - they're already sad that they lost us*. Updates will be posted first to our site at http://vcfmw.org, as well as our mailing list, which you can join there. Thanks to all who have attended in the past and are considering it this year. This one will be something special**, for sure. -jht * Nothing wrong with the old place - we just outgrew it! ** Note that that is a measure of magnitude, not direction.
