Pacific Educational Systems VPU-1 External Voice Synth

by mbbrutman-cctalk＠brutman.com

This is an external voice synthesis box based on an Intel 8031 micro-controller and a TSP5220CNL synthesis chip. It has an RS232 interface, volume and tone knobs, a headphone jack and an RCA jack for external audio. Does anybody remember these things and how to talk to them? I've tried all of the various bps rate and parity combinations from 300 to 19200 and I can't get anything response (data or sound). Thanks, Mike

Free: Stack of Victor or Sirius floppy disks

by les＠frii.com

The Victor 9000 had a variable spindle speed, I cant remember if the drive spun faster on the inside or outside tracks. Also, the index hole detector was not used. Many of the drives did not have a index detector, on the drives that did have an index hole sensor, it worked just as well without it plugged in. I got in a argument about the ability to use hard sectored floppies in the Victor 9000 with a Victor sales rep once. Even after I showed him that the index detector was not connected, he still didn't believe me. Les

Reordering S-100 PCBs

by lynchaj＠yahoo.com

Hi! I am putting together the next set of S-100 PCB reorders for the S-100 hobbyist group. The two boards I would like to order next are the S-100 EPROM and S-100 IO boards. So far, I have eight builders on the waiting list for the S-100 Flash/EEPROM/EPROM/SRAM board http://s100computers.com/My%20System%20Pages/PROM%20Board/PROM%20Board.htm I have eleven builders on the waiting list for the S-100 Serial IO (with USB and Speech Synthesis) http://s100computers.com/My%20System%20Pages/Serial%20IO%20Board/Serial%20IO %20Board.htm I need about reasonably firm 20 builders on the waiting list to warrant a PCB reorder. Both of these boards are going to be respins to correct any issues from the original boards. They are useful in any S-100 system and offer full IEEE-696 compatibility. Please contact me by email LYNCHAJ at YAHOO.COM if interested in either or both boards. They will be $20 each plus $3 shipping in the US and $6 elsewhere as per usual arrangement. I will combine shipping on multiple boards to reduce shipping depending on weight. Thanks and have a nice day! Andrew Lynch

Very handy if you're > using them with a PC/AT controller ;-) I know it's easy to generate this signal with an inexpensive microcontroller, but I'm curious what drives have this feature. I have a TM848 (can't remember if it's -1 or -2 - I'd probably have to pull it from the Dataram Qbus chassis it's in to check, but since it's meant to emulate an RX02, it's *probably* a TM848-1) that I was planning on rigging to a PC-class machine at some point to image my pile of RX01 and box of CP/M 8" floppies. Of course with all the DEC gear I have, I might as well look into using vtserver to pull down RX01 _and_ RX02 images from a real RX02 drive, but I still have plans to build a PC-based multi-media floppy imaging box, so I'm keeping my eye out for a preferred model of 8" drive for that purpose. So far, I really only know a little bit about the SA800s and the TM848s (and the Calcomps used in RX01s and RX02s, but I'm not likely to hang one of those off of a PC). Anyone have any recommendations for good drives to use with PCs? -ethan

6805 equipment pulls

by legalize＠xmission.com

Hi, A neighbouring hacker space has access to some Motorola 6805 equipment pulls. These are 6800s with some amount of on-chip RAM, ROM and IO. I have no idea what the ROM might contain or if you can circumvent the ROM with your own code in off-chip RAM. They don't have any plans for these chips. If you are familiar with them, we'd like to learn more about them. If you need some for your project, just let me know. -- "The Direct3D Graphics Pipeline" -- DirectX 9 draft available for download <http://legalizeadulthood.wordpress.com/the-direct3d-graphics-pipeline/> Legalize Adulthood! <http://legalizeadulthood.wordpress.com>

WTD: 8-inch floppy drive

by classiccmp＠philpem.me.uk

Hi guys, I'm trying to track down an 8-inch floppy drive to read an Intel MDS M2FM disc I've been sent for adding to the DiscFerret decoder engine. Specifically: it's an ISIS boot floppy, in SS/DD format. Does anyone have a spare 8in drive gathering dust in a corner somewhere? Based on the prices on Greed-Bay, I get the impression most of the sellers have been engaging in some form of abuse of illicit substances.... I mean, seriously, $700 for a Shugart 801, "untested" (which would seem to be a synonym for "I know it's broken but I sure as hell won't admit it!") and missing the head-amp / motor control PCB?

WTD: MCM6206 RAMs

by classiccmp＠philpem.me.uk

This just keeps getting better. It seems the failed EEPROM chip in my logic analyser left a parting gift: it spiked the D4 and A9 lines on its way out. In other words, it's killed half a dozen bus transceivers (74F244 and 74F245), and probably the two MCM6206 high-speed RAMs as well... Does anyone have any Motorola MCM6206 series parts to hand, preferably in the J-lead surface-mount package? The parts installed now are MCM6206DJ35, but other (faster) speed grades should be fine too. I need at least two of these, but preferably four or five so I've got spares for future use...

MFM to IDE was RE SCSI -1 to IDE and SD project

by lynchaj＠yahoo.com

Hi Ian, please note I said 'feasible'. Given enough effort and money I am confident that it is possible to build an MFM to IDE adapter. However, I do not think it is feasible as a hobbyist project. I may be wrong and maybe someone will produce such a device. I look forward to seeing it if and when it happens. Thanks and have a nice day!

I think it's doable. Just, more complicated than, say, SCSI to IDE. SCSI to IDE is a great project, but at least, for me, I've got plenty of SCSI drives.

SCSI -1 to IDE and SD project

by lynchaj＠yahoo.com

Hi Rod, I do not think an MFM/RLL (ST506/ST412) to IDE bridge board is feasible. The SCSI-1 and IDE interfaces are purely digital and the drives are intelligent enough to abstract much of the realtime complexities of communicating with the hard drive itself. As a result the bridge board between the SCSI-1 and IDE is relatively simple and a basic Z80 embedded controller is able to accomplish the data transfer relatively easily. It is well suited for a community hobbyist project like the SCSI to IDE/SD bridge board we are working on at Vintage-Computer.com forums. MFM/RLL (ST506/ST412) interfaces are a high speed extension of the Shugart floppy drive interface with some additional signals. It is a hard realtime interface and low level way to communicate with the hard drive. As a result it would require an extremely sophisticated high speed controller to interpret the signals to and from the MFM/RLL (ST506/ST412). A simple Z80 or microcontroller based controller would not be able to accomplish the task in my opinion. It may be possible but I believe it would be an expensive commercial device and probably quite rare. The SCSI-1 to/from IDE/SD project is a hobbyist community project and I think would be quite helpful to the wide array of legacy/vintage/classic devices which use SCSI-1 drives. So far, I have heard from owners of the obvious microcomputers like Atari, Amiga, Apple Mac, Sun workstations, DEC, etc. However many other devices used SCSI-1 devices such as synthesizers, a variety of test and lab equipment (?), sewing machines (?), photocopiers (?), and other devices I would have never suspected used SCSI-1 drives. At the moment, there are 6 builders with the prototype PCBs but none have reported a working build yet. The parts are very common and the design uses only "hobbyist friendly" construction for easy assembly. However, the software still needs to be written which should be largely reuse of existing Z80 code from existing N8VEM projects. If you or anyone else is interested in working on the project please contact me. I still have 4 remaining prototype PCBs. My goal is to get this project up and running before the SCSI-1 drives become difficult to obtain such as 100 TPI floppy drives, MFM/RLL (ST506/ST412) hard drives, and other uncommon storage medias. All of the technical information on the project is available at the N8VEM wiki. It will be free/open and publicly posted for community benefit like the rest of the N8VEM boards. Please read the existing technical documentation before critiquing the design. http://n8vem-sbc.pbworks.com/w/browse/#view=ViewFolder <http://n8vem-sbc.pbworks.com/w/browse/#view=ViewFolder&param=MINI%20SCSI%20 to%20IDE%20prototypes> &param=MINI%20SCSI%20to%20IDE%20prototypes Thanks and have a nice day!

Several weeks ago there was a discussion on CCTALK about a free/open SCSI to IDE and SD project. I designed a PCB using the Z53C80 and a Z80 with RAM/ROM/UART/IDE and SD. There is a prototype available waiting for some interested builders to take on the project. As far as I know none of the builders have a completed unit although I think if we had at least one working unit the project would make some real progress.

Using tu58em to boot standalone backup on 11/750 ?

by david_comley＠yahoo.com

Has anyone ever tried using the tu58em program to boot a VMS 5.2 install standalone backup on an 11/750 ? I ask because I am attempting to do so, and I keep encountering mount verify errors when I get to the fourth tape in the set. I see a lot of web references to using tu58em in the PDP-11 world, but not so much on the VAX. I suspect some sort of protocol error caused by an invalid response from the emulator. Same problem with the VMS 5.3 install, by the way. Before I pursue this approach to installing the OS any further I thought I'd see whether there's a known issue trying to do this. -Dave

Does anyone have a manual/datasheet/doc the for the Fujitsu Etherstar 86950B Ethernet controller? My Google-Fu has failed. I'm writing a driver for an old VMEBus card and there are a few things that I'd like to understand better. KJ

S-100 4MB SRAM PCBs

by lynchaj＠yahoo.com

Hi! I did a recent reorder of the S-100 4MB SRAM boards and have a few left over. If you would like one they are $20 each plus $3 shipping in the US or $6 elsewhere. These boards were very popular last year and many builders requested for another batch. I got some extra PCBs anticipating there would be others coming along later. These boards have no known defects AFAIK and dozens builders have gotten them since last year. They can use either SRAM or Flash memory chips and are all DIP/PTH construction for easy assembly. Please contact me if you would like one or more. Thanks and have a nice day! Andrew Lynch PS I set up a Google Group for announcements on the S100computers and N8VEM S-100 projects called N8VEM-S100

OK, does anyone know what this is?? http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=140474798391 Google fails me on this, other than to find that a guy once wrote a manual for it. My (uninformed) guess is that it's an early TCP/IP stack for Windows 3.x. I'm almost tempted to buy it to find out, were it not for the Canadian shipping. -- jht

VCB02 woes in a MicroVAX III

by derschjo＠mail.msu.edu

I'll attempt to keep a long story short here: I have over the past few years been putting together a MicroVAX III; I have a KA650-B CPU, 16MB of memory, a CMD SCSI interface and a DEQNA ethernet interface. A couple of years back I got a VCB02 and finally this week I got ahold of a BC18Z cable so that I can actually connect the VCB02 to a monitor/keyboard/mouse :). I've got everything installed and wired up this evening, the problem is, I can't seem to get it working. On powerup, the monitor syncs with the video signal the VCB02 is sending out (and I get a brief screen with some garbage on it followed by a black screen), and the keyboard emits a couple of very short beeps during the diagnostic cycle, but the MicroVAX doesn't seem to acknowledge the existence of the VCB02. All diagnostics pass. So, a few questions: - Is there a specific ROM version I need in order for the KA650 to recognize the VCB02? I have V1.2/0123 which seems pretty early (given that I've seen references to 5.3 on the 'net). If so, anyone know where I can find a dump? - What keyboards is the VCB02 compatible with? I'm using it with an LK201 from my VT220 currently, and all four LEDs are lit constantly, which starts me to wondering... - Are there any restrictions on slots/card ordering I should be concerned with? This is in a BA23 backplane (which originally housed a MicroVAX I) Thanks! Josh

RL02 head numbering

by chrise＠pobox.com

I'm trying to fix up an RL02 that throws constant errors in XXDP's ZRLMB1 test from head 1. In, http://www.bitsavers.org/pdf/dec/disc/rl01_rl02/EK-RL122-TM-001_techAug82.p… "RL01/RL02 Technical Manual" on page 58, it shows upper head (1) and lower head (0). But, http://www.bitsavers.org/pdf/dec/disc/rl01_rl02/RL02techDescr.pdf throughout refers to the upper head as 0 and the lower as 1. Which "1" is ZRLMB1 refering to? ;-) Chris -- Chris Elmquist

VCF East 7.0 updates

by evan＠snarc.net

Some updates .... 1. VCF East 7.0 is on Facebook: http://www.facebook.com/pages/Vintage-Computer-Festival-East-70/12799934393… Yes, that link stinks. Facebook says we need 25 page fans before we're entitled to a customized link. So please "like" and become a fan of our page ASAP. 2. Dan "Ragooman" Roganti will run a "Build your own transistor logic circuit" workshop. Neat! 3. Our exhibit registration is open at http://www.vintage.org/2011/east/index.php (click the 'exhibits' link on the top right), BUT, it currently only works for people who previously registered. It's not working for new registrants. We're trying to fix that. 4. So far we have lectures confirmed about UNIVAC/Unisys and about the heydey of homebrewed microcomputing in the NYC, NJ, and Philadelphia region. We're working to create lectures about Monrobot; Bell Labs' TRADIC; Electronic Associates; the IBM 1130; Jason Scott's Get Lamp; and our future museum plans. We'll announce those when they become official. 5. So far four exhibitors signed up. We expect 20-30 overall, in line with our past VCF Easts. 6. We'll also have consignment sales, a used book sale, and museum tours. 7. This year's VCF East t-shirt will be AWESOME. The only way to get one is to be there. :)

Early days of TCP/IP on the desk (was Re: Microsoft Online)

by tshoppa＠wmata.com

>> I was on the MSN team and we were building an AX.25 network > Have you read "Barbarians Led by Bill Gates" ? > What a mess. Apple was no better, though (eWorld, etc.) I don't > remember much push for broadband as mentioned in "Barbarians" I came from the academic side where Ethernet networking had been standard for some time by the mid-90's and getting networks of VAXen and Suns to interoperate was a breeze. In contrast the mid-90's era focus by consumer OS's (read that as "Windows and bolt on products") on the modem as the lynchpin in networking, was simply bizarre to me. By that time on PC-clones with MS-DOS we had been using the NCSA stack for Telnet and FTP and all the other good stuff, for many years. Completely stable and just worked. I was especially fond of a simple configuration of MS-DOS Kermit. I was completely stumped by Windows 95 networking and Trumpet Winsock. They made it a zillion times harder. To this day whenever I have to configure Windows networking and am forced to click on all the variations of "No I don't have an ISP but I can still connect to the internet" I still become enraged.

Bit of DEC Trivia

DECtape uses Manchester encoding, so it is self-clocking. Yes, but you need the clock track in order to write. So, read is self-timed, and write is done with the help of the timing track. And yes, the speed of the motor will affect how fast data comes in/out, but only indirectly, since it's the clocking off the data from the tape that matters. Tricks to increase speed would be to run an already formatted tape faster or to format a tape at a slower speed. Formatting a tape at a slower speed will also make it possible to fit more data onto the tape (obviously). > Head skew relative to the timing tracks becomes more of an issue, but even that was mitigated by putting redundant tracks > on different parts of the tape and or-ing the heads together. I'm not sure how much head skew could happen. The data from the tape is read by just one head, with 10 tracks. So, the timing track is read at the same point as the data. You could possibly get some kind of skew if the signal was delayed through the electronics. > The trick with holding your thumb on the reel became necessary when DEC started shipping less tape on the reel than > certain PDP-8 operating systems expected.

In 1994 and early 1995, I installed Trumpet Winsock on a lot of Windows 3.1 machines. Unfortunately, even up to the August release of Win95, the typical desktop for our users was (admittedly obsolete by that time) a 386SX16 (Dell 316 or some variety of Compaq box) with 2MB of RAM, no hard disk, a 10Mbit Ethernet card, and booting off of a floppy to attach to a Novell Netware server to load apps (Lotus 1-2-3, Word Perfect, e-mail (DaVinci!), etc). The Novell servers, handling hundreds of users each, were high-end Compaq 486 boxes with up to 64MB of memory and a gig or two of disk. If you were blessed by the Network Engineer, your login could be permitted to load the seat-license-locked TCP stack for DOS/Novell and use Telnet and FTP. I had a lot more fun in the science lab where the standard machine was a Mac IIci or one of the SPARCstations (which had TCP/IP set up by default). But thank you, Ian, for your work. I did enjoy setting up TCP/IP out of the box when Win95 came out, vs having to go get bits and have grudging support from our Network guys about getting addresses, etc. (they used to be *very* stingy with assigning out blocks of IP addresses before the days of NAT Firewalls and private address space - the proliferation of TCP/IP to every desk pushed that change). -ethan

WTD: 28C16 EEPROM in PLCC package

by classiccmp＠philpem.me.uk

Hi guys, Seems the EEPROM which stores the MAC address in my HP 16500B logic analyser has developed amnesia. That is to say, it forgets everything a few days after being programmed, and as of today it won't even program correctly. Does anyone have a spare PLCC-packaged 28C16 EEPROM or two knocking about? Ideally I'd like another of the original part, a Samsung KM28C16J-20, which is specced for 200ns. A Catalyst/ONsemi CAT28C16 or any of the many variants should also suffice... My local supplier lists these as "special order only" -- with a ?16+VAT charge to do so, a monstrous minimum order (something like 100 units) and a three week factory lead time. I need maybe three of these at most... Thanks, -- Phil. classiccmp at philpem.me.uk http://www.philpem.me.uk/

Radius Pivot monitor help needed

Has anyone ever worked with a Radius Pivot monitor? I'm trying to get one hooked up to a Mac IIci or IIsi but I need drivers and an appropriate video card. I'm pretty sure I have both but finding them at this point will be a major pain. If anyone has the drivers handy, and can let me know what an approproiate video card would be to interface the monitor to a Mac, I would greatly appreciate the help.

Sniping Does Not Require Justification!

by jfoust＠threedee.com

At 07:58 AM 2/21/2011, Liam Proven wrote: >Sniping subverts how auctions work. In the average real-world auction that I'm accustomed to, at best as a bidder you might need to register in advance. Once you're there, there is no requirement to notify all other bidders of your interest in an item. In fact, bidders tend to be quite subversive about their interest in an item, so as not to draw attention to themselves, the potentially more-valuable item, or their interest in it. You're free to bid "in the last second." Yes, the auction continues at that point, and that's different than eBay. You're not just wishing for an auction format where all bidders must make their presence known, and then a moment where no additional bidders can register before bidding begins. You can't seriously be wishing for an auction format where all other previous bidders and their max price be known before you bid. We can't just wave our hands and think that it would solve the problem if eBay extended the auction N minutes beyond every moment there was a bid. That would greatly encourage the demand for and use of automated bidding tools. Part of the appeal for buyers and sellers on eBay is that you are generally searching items you know will be for sale and that you can bid on immediately. Would you be happier if multiple proxy bidders all registered to bid and made some token bid just to be part of the game? - John
