Can Windows 98SE run on an Intel I7 with SATA gard drives?

There is that package you can add (my copy is in a self-extracting archive, called "nusb23e.exe") that recognizes USB drives, etc. I run a number of USB devices (memory sticks, mice, etc) on my 98SE's and they all work fine. My approach to keeping my 98SE machines running is _lots_ of spares of all kinds. They were easy and cheap to acquire a while back - they're a lot harder to find now, those machines are all totally obsolete. Noel

Can Windows 98SE run on an Intel I7 with SATA gard drives?

For most of what I did (and do, for that matter), it worked very well; it would have been nice if it recognized USB storage devices natively. > The Pentium III hardware is more than a bit of a concern.

The hardware is worth worrying about. Replacement power supplies will probably continue to be available, but those disks are likely to be unobtanium, and are practically guaranteed to fail at some point. My personal "sweet spot" for operating systems was Windows XP, and it was with with quite a bit of trepidation that I eventually moved on to Win7-32. Eventually, I needed a new laptop, and moved to Win8.1-64, which took a great deal of massaging to make comfortable (the "Classic Shell" product is very nicely-done, and free, and went a long way towards making things usable). However, there were still a lot of problems: - 64 bits absolutely breaks any 16-bit code, whether it be a DOS program or a Windows 3.1 application. Unfortunately, I have a large industrial application that I've maintained for the last 20 years (things last a long time in industry), written in Visual Basic 3. Maintaining it under XP was easy, because XP would just magically fire up ntvdm (NT Virtual DOS Machine), then run a Windows compatibility layer (wowexec) on top of that; this all made everything work just fine, and with almost complete transparency. For DOS programs, it would capture any physical I/O calls (for example, to the com port addresses) and do a fantastic job of emulating them - again, completely transparent to the application program. Win7 (Vista, actually, but nobody cares about that) broke all of that. - I have an application that I like and use a lot (CircuitMaker-2000) which runs fine on every version of Windows from 98SE on up to at least Win8.1-64 bit, and presumably Win10, though I haven't tried it. However, printing has been broken on everything since Win98SE. - The versions of Office and QuickBooks I was using started exhibiting numerous problems; Word continued to work "OK", sort of, but QB was completely unstable, and I depend upon it to run my business. - The security implementation of pretty much everything, starting with Win7, makes a lot of things difficult; registry writes are now tightly controlled, registering DLLs and OCXs requires elevated privileges, network firewall functions are highly complex, convoluted, and depending upon the version (Premium, Pro, Ultimate, etc.) the tools may not even be provided to completely manage all of this. My solution to most of this (except some of the network issues) has been to use VirtualBox. It's free, and does a great job of handling XP as a guest operating system. With XP, mouse movements, virtual disks, networking, and even the clipboard are all nicely integrated into the host operating system, so my XP machine is always just a keyboard shortcut away. I also have a virtual Win98SE machine, to handle the printing issues with CircuitMaker. This is less well integrated, in that the mouse capture is clumsy, and the file system integration features aren't there, but that was easy enough to get around by just creating shared folders on the host, and setting them up as network drives on the Win98 VM. It took a solid week of tinkering to get everything set up to my satisfaction (I have a lot of disparate interests, and their associated applications), but now I have a setup that I'm very happy with. (I broke down and advanced a single version - to 2003 - for both Office and Quickbooks, so those both run happily in native mode now.) > QUESTION: Is it even possible to run Win98SE on a current > Intel I7 CPU with SATA hard disk drives? I realize that it might > be possible under a virtual machine, but I really want all of the > advantages that Win98SE provides. One problem, of course, Almost certainly not, at least practically. Even if you can get it to boot and install, it will have no idea how to handle any of the modern peripherals, and drivers certainly won't be available. So sound won't work, the screen will be limited to VGA-16, and I'm not sure about the keyboard and mouse (there's a reasonable chance that the BIOS will emulate the legacy PS-2 devices, just as it's abstracting the details of the SATA disks). I really think that your best solution would be to go the virtual route. Get a huge monitor (mine's 28" 2560 x 1440 - I would have preferred an even larger curved 4k unit, but HDMI wouldn't support it at full resolution, and that's all my laptop has) - or even a dual monitor setup, a terabyte or two of hard disk, and plan to spend that week tinkering. As much as you like Win98SE (and I completely understand why!), you might find that XP will still run everything you're interested in, and VirtualBox handles that very well. There's every reason to expect that the virtual machine will continue to be stable and supported for the foreseeable future (like 20+ years), regardless what the host Microsoft operating system evolves to be. Of course there's no reason not to have both XP and Win98SE VMs, as I do - I even have a Win3.1 machine, just for the fun of it. For backup, I stubbornly store everything in two large directory trees: C:\Library and C:\Data (actually, I have a C:\Music as well). The C:\Data tree has absolutely everything that I've ever worked on: source, designs, correspondence, pictures, taxes, email store, and the VM disks. It takes a bit of persuading for the modern versions of Windows to accept C:\Data as the "My Documents" folder, but it can be done. The C:\Library tree has all kinds of documentation (PDFs of manuals and data sheets, and lots of just plain reading material), as well as a large sub-tree called Distrib that has the installation sources for all my software applications. In some cases, this is in the form of ISO CD-ROM images, but mostly it's sub-directories with the contents of all those. Everything is there: all the Visual Basic/Studio versions, all the Office versions, compilers, Adobe, Photoshop, PLC and other development systems, SolidWorks and AutoCAD, and even the installation media (in both ISO and file formats) of the Microsoft OSes as well (DOS through Win-7). All of this fits comfortably on the single terabyte drive that came with the laptop, and backing up is a simple matter of either just copying the two (three) large trees, or using some difference software (I use a free program called TreeComp, but there are many others too) to sync everything to an external USB (3.0 strongly preferred) drive, which I keep in the fire safe. Moving to a new computer is simply (if time-consumingly) a matter of copying those trees to the new machine, then installing the software directly from the \Library tree - no other CDs required. > Alternatively, does it seem reasonable to attempt to keep a > system with a Pentium III CPU and associated hardware > running for another 20 years? It's probably possible (although the weak link would probably be the disks), but if it were me, I'd treat that more as a hobby project than as a machine I depended upon. So far, I've successfully avoided giving up the applications and "way of doing things" that I like and am comfortable with, while still migrating to current hardware and software. I have to admit, effectively unlimited speed and space are quite nice... ~~ Mark Moulding

What to Do with a PS/2?

by johnwallace4＠yahoo.co.uk

[massive snippage, sorry] Several folks have mentioned Dave Cutler. There's a book called "Inside Windows NT", by Helen Custer at Microsoft Press. The aforementioned Dave Cutler (architect of software including RSX11, VAX/VMS, VAXELN, and WNT) wrote a foreword for it. There, he says the goals of NT were "portability, security, POSIX compliance, compatibility, scalable performance, multiprocessor support, extensibility, and ease of internationalisation" (p xviii in my copy). Obviously some of that list has fallen away during the NT/Gates years (portability? security? POSIX?) WNT's kernel stuff, process architecture, etc has some VAXELN heritage. VAXELN was a not particularly well known (even inside DEC) Cutler project for a distributable realtime OS which would feel comfortable for VMS programmers without being VMS, and allow distributed RT applications to be developed without need to understand low level hardware specifics and OS kernel interface details. VAXELN incorporated early examples of a process model which also incorporated threads, and a nice approach to interprocess data sharing (a distributed naming service, transparent messaging between apps whether on the same node or separate, etc). Marvellous stuff, some of which duly made its way into NT, though many writers understandably missed the VAXELN connection (it is briefly mentioned in Custer's book). Those who are moderately familiar with the internals of NT, VMS, and VAXELN (which probably isn't that many people) will recognise some of the VMSisms that VAXELN didn't have and which are also not present in NT. At a detail level, where are WNT's ASTs, where are logical names? And at a big-picture level - VMS is a mostly monolithic setup (one single kernel address space), WNT originally wasn't, though over time Gates forced changes towards the monolithic approach, e.g. moving assorted drivers and subsystems into the kernel for performance reasons that for security and robustness reasons should have been isolated from each other. Neither VAXELN nor NT have quotas or privileges as such. There is no meaningful security architecture on WNT; on VMS there is. And so on. But fewer people will know VAXELN, and so the Cutler project that gets the publicity in the "where does WNT come from" context is VMS (it is, after all, still pretty close even if VAXELN is closer). And the WNT name? Who knows. The magic words PRISM and MICA perhaps come into this discussion somewhere too, but I know nothing about them. Have a lot of fun. John Wallace (not to be confused with John Willis!) [Repurposed with minor edits from some of my occasional WNT/VAXELN/VMS ramblings on comp.os.vms]

Jacques Laporte's HP-35 webpage

by kylevowen＠gmail.com

Does anyone have the full webpage from here? http://home.citycable.ch/pierrefleur/Jacques-Laporte/index.html Lots of broken links, missing images, etc. His former site was at http://www.jacques-laporte.org as far as I know. Here's a page that is particularly broken: http://home.citycable.ch/pierrefleur/Jacques-Laporte/HP%2035%20Display.htm I'm mostly interested in his work on reverse engineering the HP-35 hardware. I know I used his site a couple of years ago, and it was very helpful in understanding the 35. Very sad to hear of his passing. The Wayback Machine doesn't have it apparently, thanks to robots.txt.

Free Apple ImageWriter I (A9M0303)

by paul＠mcjones.org

I bought it new in 1984 or 1985, and used it for six or seven years until I bought a laser printer. It?s been in its original packing box ever since. I just powered it up and verified that the line feed and form feed buttons seem to trigger appropriate movements, and the print head seeks over to the left margin. First priority to someone who will pick it up in Mountain View, California; otherwise to someone who will pay for shipping. Paul McJones

Can Windows 98SE run on an Intel I7 with SATA gard drives?

by jhfinedp3k＠compsys.to

I run Windows 98SE on a 14 year old Pentium III. I have replaced the power supply twice and all three hard disk drives. It is a really good system to run the Ersatz-11 emulator for the PDP-11, specifically RT-11. Since Ersatz-11 has built-in VT100 emulation, I don't need a separate terminal emulator. I also run Netscape 7.2 for e-mail and newsgroups. And that is all - no surfing the internet or google of any sort. Incidentally, I use Ghost 7.0 for backups to DVDs. Aside from the daylight savings time changing 3 weeks too late in the spring and a week early in the fall, I really like the system and I would like to use it for another 20 years. Since I am 77 years old now, I figure that will be just about satisfactory. The Pentium III hardware is more than a bit of a concern. I would be very pleased to upgrade to 64-bit Windows 10, but the DOS variant of Ersatz-11 is not supported and I really would prefer to keep using Netscape 7.2 since I have over 100,000 e-mails and posts to newsgroups that it is important to be able to keep. QUESTION: Is it even possible to run Win98SE on a current Intel I7 CPU with SATA hard disk drives? I realize that it might be possible under a virtual machine, but I really want all of the advantages that Win98SE provides. One problem, of course, is that there must be a patch to Win98SE when more than 1 GB of actual physical RAM is present. But I can't seem to find out anything else. What leads me to believe that there is a reasonable chance is that the IDENTICAL 3.5" floppy media is able to boot DOS >from drive A: and run on both the Pentium III (with a 3.5" HD floppy drive, of course) AND on a Q9550 Core 2 quad CPU which also has a 3.5" HD floppy drive which currently runs 64-bit Windows 7 from the C: drive, of course, using three SATA hard drives where the C: drive has an NTFS file structure and all the other partitions on all of the SATA drives have a FAT32 file structure. So without really understanding the details of the device drivers and the BIOS, it would seem that the SATA drive hardware and software is compatible. Ghost 7.0 is a file on the F: drive of the Q9550 CPU (first extended partition of the 1st physical SATA hard drive). Ghost is able to take a file produced as a backup image on the Pentium III system (and copied over the router connecting the Pentium III and the Q9500 systems - that also provides internet access for both systems) and re-create the same files on a specified partition on the Q9550 via the Ghost 7.0 program while the Q9550 is booted from the 3.5" floppy media. Since the SATA hard drives on the Q9550 system don't seem to have a problem with DOS on the floppy, then I have some hope that Win98SE could manage them as well. Has anyone experience or knowledge about being able to run Win98SE using an Intel I7 CPU with SATA hard drives all of them using a FAT32 file structure? Alternatively, does it seem reasonable to attempt to keep a system with a Pentium III CPU and associated hardware running for another 20 years? Jerome Fine

MU-BASIC V2 and RT-11 V03B distribution disks.

by mattislind＠gmail.com

I found some 8 inch floppies with distribution kits for MU-BASIC V2 and RT-11 V03B. I imaged those and put them here http://www.datormuseum.se/documentation-software/rx01-and-rx02-floppy-disks if anyone is interested in playing with MU-BASIC. There are both RAW disk images and to be used in SimH and like and also DMK/IMD files. The system that floppies came with is this little ( http://www.datormuseum.se/computers/digital-equipment-corporation/pdp1103-l) system once used at Scania in S?dert?lje.

HP 9845 Option ROMs

by ball.of.john＠gmail.com

So in the past few weeks I've been playing with my latest aquisition, an HP 9845A that's been upgraded at some point to a 9845B. The filter caps for the PSU are in the mail still and I have yet to actually see the system turn on so I've been working on other projects in the meantime like cleaning the machine, troubleshooting faults in the floppy drives it came with and sourcing a food dehydrator to bake the tapes it unexpectedly came with. It's a fairly basic machine without the internal printer or second tape drive. Only the I/O, graphics and Mass Storage ROMs are installed and there's at least one other option ROM module not accounted for according to one of the manuals that came with. In fact it seems the option ROMs aren't common to begin with or at least they are not cheap on ebay. I seem to remember a few years ago someone out further West than I am who also had a 45 discussed some sort of ROM board that acted like the PRM-85 ROM board for the HP 85 and let you load whatever ROMs you wanted onto a modern EPROM and do away with HP's silly modules completely however my memory is fuzzy and I can't seem to find any mention of such a device on the internet. What I did find was the System ROM replacement board on hp9845.net but it doesn't mention the ability to add in images of the option ROMs he has available on his site. Anyone else heard of this mysterious adapter? -John

HP 9000/380 console? software? (was Re: HP 9000/382 Questions)

by spacewar＠gmail.com

I've borrowed an HP 9000/380 from a friend, along with a 9122D floppy drive, but no software. It has an A1416A Color VRX DIO-II "Kathmandu" video interface, but I'm hoping that I can just use the serial port as a console. Does the DE9 serial console use the IBM pinout? Do I have to pull the A1416A to get it to use the serial port as the console? Is there any software that can be booted on it from the floppy, such as perhaps non-HP-UX BASIC?

BC11A paddle boards

by ggs＠shiresoft.com

I just received the first of the BC11A paddle boards (so that I can now create my own BC11A cables). I made two variants of the boards. One where the cables come out the ?top? and another where the cables come out the ?side? (so you don?t have to ?fold? the cable in a number of different applications such as RK05s). The ones that arrived today are the S or ?side? variation (as opposed to the T or ?top? variation). I immediately noticed (why I didn?t see this when I was reviewing the board layout previously I?ll never know) is that one of the cable connectors is too close to the edge. It wouldn?t be a problem except that I chose to use connectors that have cable retention latches. The latches protrude from the board edge by ~0.02?. So once I verify that these work, I?ll move the one connector inward ~0.5?. I have plenty of space, I just don?t know why I put the connector that close to the edge. *sigh*. For these boards, I?ll probably just file the latch down a bit to get the appropriate clearance. BTW, trying to get the connectors onto the board (I haven?t soldered them in yet) was tight. That?s the problem with trying to get 60 pins to all line up correctly. But they fit and are *snug*. I probably won?t go and do any testing until I get the other boards in so it may be a couple more weeks (the boards weren?t supposed to *ship* before 2/8). For those who?d like to know, I probably will not be making a production run of these boards unless I get a *lot* of interest (100 boards or so). If you want some, let me know and if I get enough interest, I?ll do a production run. TTFN - Guy

DEC TS05 mains switch

by ard＠p850ug1.demon.co.uk

As I mentioned some time back, I am currently restoring a VAX 11/730 system. It is the version with the TS05 on the top, I currently have the TS05 in many bits while I sort out at least 4 faults with it (No, I've not sorted out the TU58 console tape drive yet, I needed something else to get on with while I was thinking about that). One problem with the TS05 (Rebadged Cipher F880E, of course) is the mains switch. Only one pole (double pole switch) opens, and it gave quite a nasty spark when I put mans on the unit. So I want to replace it. The problem is that I have never seen one like it before. It has _5_ terminals. Four of them are what you'd expect for a double pole on/off switch, The other is for the built-in neon indicator. Rather than just wiring it across the output side of the switch (as most do), this unit has a neon with the correct series resistor for 115V operation wired between one of the output side terminals and the fifth terminal. The TS05 puts the neon in parallel with the supply for the 115V blower unit. Thus the power on indicator gets 115V no matter how the voltage selector is set. The switch is the stadard size for double pole rocker switches (30mm * 22mm panel cutout, isn't it?). If I can't get the right replacement I have several options : 1) Fit a normal 230V illuminated rocker swtich, and asssume I will never change the voltage selector setting (but I am trying to keep this machine electrically original). 2) Fit a normal non-illuminated rocker switch. It will then be OK on any mains voltage, but no power-on indicator, and it's not electrically original 3) Fit a non-illuminated rocker switch and find a place to fit a separate neon indicator. It is then electrically original, but won't look right 4) Try to mend the original switch 5) Try to make an equivalent using bits of switches I can get. Does anyone have any ideas where to get the original switch from? -tony

Anyone happen to have a spare set of outer rackmount rails for an RK05? I have the inner rails that attach to the drive, and I'm trying to track down the outer parts that attach to the rack, with the inner slide. Getting very close to having a semi-respectable PDP-8/m system put together, just need to get the hardware mounted. (And track down the impossible RK05 cabling. And debug the controller. And probably a dozen other things...) Thanks, Josh

Terminal Emulation for Windows - supporting Kermit File Transfer

by lehmann＠ans-netz.de

Hi, I'm using extensivly C-Kermit on my FreeBSD host to connect to various serial-line-only Systems. They also have a kermit executable so I'm using kermit -s to send data from those systems to my FreeBSD system and also getting files from my FreeBSD host to the other systems is working fine. I'm now looking for a way to get this "kermit file transfer" functionality from Windows but had no luck so far. Is there free-for-use Kermit alternative arround to be used for Windows or an other Terminal Emulation which supportes Kermit File Transfers "out of the box"? Yes - I know Kermit 95, but this is not free. Regards, Oliver

Introduction and RK05J Drive cabling

by saburwulf＠gmail.com

Hi there, long time viewer, first time poster. First an introduction: My name is Joshua Stetson and I'm a software engineer by trade. My earliest memories have always involved computers starting with a DOS based Zenith 8088 where I played some of my first games. My first foray into "classic" computing was on a Commodore 64 which my Uncle gave me while I was still in Jr. High. I'd already been introduced to programming at an early age, so this machine was an absolute treat to me at the time as it was my first step into assembly language. As time progressed, my interests turned older and I began a collection of S-100 gear including an IMSAI 8080 and a SOL-20. Over the past couple of years, I've managed to work back even further, piecing together a PDP-8/e system from various parts collected over the past 4 years and now I have a fully working 8/e including 32kw of core and an RK05E card set. I've been running the system using Kyle Owen's os8diskserver and David Gesswein's sendtape utilities which both work absolutely wonderfully. It was amazing to be able to run Adventure on a native system! I'd like to send a shout out to Kyle for the os8diskserver, that is some pretty awesome work there. David for his software and archive of DEC documentation which was indispensable for helping me debug a few boards and get everything running and tested. I also want to thank Vincent Slyngstad for his help and support on some questions. Now to my ask: Recently I've found a pair of RK05J drives and a few disk packs. One of my drives seems to be in fully working order, the other the blower is not working, so I'm working on fixing that right now. I'm currently missing cabling for connect these drives to the RK05E board set. If anyone happens to have an extra cable set they'd be willing to part with so I can bring these beasts back to life, I'd appreciate it! Ideally I would like to find the following: 7009026 Cable which is two ribbon cables with a M933B or C flip chip on the other end The interface cable between the two drives: BC11A The terminator card M930 At minimum, I'm pretty sure I'd only need the first cable to run one of the drives, but I'd appreciate any help from those who have more experience. Also, I don't have a rack for this equipment yet, so I'm running it all tabletop, but I'm in the market for a rack + rails (I only have the rails for the equipment, but not the ones that mount to the rack itself. Any leads on more 16-sector packs would also be appreciated! Also, still hoping to get the extended arithmetic boards, RTC, and possibly a TSC8 Timesharing option as I have 4 SLUs and would love to try out some timesharing. On a side note, I'm looking to perhaps sell or trade my SOL-20 sometime soon. It's 100% working as I restored it about 3 years ago. It works great, but I'm looking to part with all of my S-100 equipment to focus more on DEC. Thanks!

opening the drive door/lid of an RM03 ?

by henk.gooijen＠hotmail.com

Hello readers, I cleaned the first of my RM03 drives today. The drive is quite clean even after several years of no attention. Just a few spiders webs and tiny dead spiders, and little dust. I picked up this drive in Turin Italy, together with Edward several years ago. I cannot remember doing it, but the head lock pin was in the lock position. After cleaning and a good inspection (I found a small metal bracket piece next to the PSU output plugs, and have not found where it came from!), I mounted a mains power plug to the drive cable. Massbus cable is attached to the drive, the other end is not connected to anything. After setting all circuit breakers ON (two inside the drive, two at the rear side next to the running hours counter), I plugged the mains in and switched mains on. I hear humming of the fans, so it seems OK. However, this is my problem: the door latch stays locked, I cannot open the lid. I want to open the lid to clean the inside of the drive bay. After some reading (EK-RM023-TD-001_RM02_03_Tech_May78.pdf), I found this in chapter 4.4 (page 4-7): The initialize sequence starts with the receipt of a Massbus INIT signal from either port A or B. This sequence is used to condition both the adapter and drive circuits to a known reset state. The functional block diagram for the initialize command is shown in Figure 4-5. The Massbus INIT signal (whether coming from port A or B) clears the AT A bit in the attention summary register in the IF module. In the CS module, it is converted to the MBA clear signal which performs the following: 1. Clears the enable search latch 2. Sets the on latch 3. etc. So, do I understand this correctly that without an initial Massbus INIT signal the lid remains locked? Or has this RM03 drive a "lock issue"? If somebody has an RM03 drive, is it possible to open the lid without Massbus cables hooked to the RH70 or RH11 controller? Is that Massbus connection required + INIT command to unlock the lid? I have not yet cleaned the other two RM03 drives, and I do not want to apply power without cleaning and inspection! So, I cannot check whether all 3 drives keep the lid locked. I forgot to take the camera with me, but I will take pictures! Thanks, - Henk

VAXELN Datagram Service

by robert.jarratt＠ntlworld.com

I am doing a bit of VAXELN programming and I am trying to get the Datagram Service to only read packets of a certain EtherType, but unless I use promiscuous mode, nothing is read. Here is the relevant code: form.format = ELN$K_NI_PTT; form.mux.ptt = 0x0360; mode = 0; pad = 0; eln$ni_connect(&status, &portalId, config.clist.list[i].control_port, &dispatchPort, &form, NULL, &mode, NULL, NULL, NULL, NULL, NULL, &pad); Anyone know why this might not return any packets at all when I wait on the port? Regards Rob

C64 system cost?

by starbase89＠gmail.com

Hey, I've been looking into getting a C64 system to play with. I'm looking for not just the computer, but a 1541, a datasette, color monitor, printer, joystick and modem, and some software. Eventually I'd like to get an SD card adapter, too. Can someone give me an idea as to how much I might end up spending on all of this? Thanks!

IDE knowledge anyone?

by lehmann＠ans-netz.de

Hi, I've built a Harddisk-Controller-Emulator for my system which accesses a IDE (PATA) harddisk with an ATMega in PIO mode. It works like a charm except for one WD harddisk. The harddisk itself works fine with MS-DOS 6.22 and FreeBSD but refuses to work with my ATMega. On reading or writing a sector, right after the command is issued, the error bit is set in the status register, and the error register indicates an ABRT. # ABRT: # indicates the requested command has been aborted due to a # drive status error (such as not ready or write fault) or because # the command is invalid. Right after power up and after the disk got ready, I issue the IDENTIFY command and read the data back which works perfectly. After that I read sector 0 and this fails. I use LBA since the harddisk states that is supportes LBA. Nevertheless I also tried accessing the harddisk with CHS mode and got the same error. I tested other harddisks which support either CHS+LBA or CHS only. All of them work perfectly. What happens after powerup to read block 0 of the disk in LBA mode: - Setup AVR ports and so on - wait until RDY gets high - wait until BSY gets low - issue a Drive/Head register Command with value 0 - wait until BSY gets low - issue a Command Register Command with value 0xEC (identify device) - *read data* - process and print out data - wait until BSY gets low - issue a Sector Count register Command with value 0 - issue a Sector Number register Command with value 0 - issue a Cylinder Low register Command with value 0 - issue a Cylinder High register Command with value 0 - issue a Drive/Head register Command with 0 + 0xE0 (LBA, Drive 0) - issue a Command Register Command with value 0x20 (Read Sector) - *read data* *read data*: - wait until BSY gets low - check ERR bit in the Status register <- set on cmd 0x20 here - wait until DRQ gets high - issue a Data register Command with no data - put /RD on low - read 512 bytes of data - put /RD on high - check ERR bit in the Status register Issuing a Command works always like setting /CS0, /CS1, /DA0, /DA1, /DA2 to low, and then set the needed signals to high so the desired command is indicated. When data has to be transfered with this command, the lower 8 bits are put then onto the port, /WR is set to low afterwards, 3 nop() are done and /WR is set back to high. Does anyone see an error what could make the drive behave like I said? - ATA IDENTIFY works, and the drives data can be read - after a read or write sector command is issued, the status register directly goes 0xd0 (busy) and with the 2nd fetch 0x59 (not busy, drq set, err set) Regards, Oliver

VT100 PSU smelling.

by mattislind＠gmail.com

Short: R27 in my VT100 PSU is hot and smelling. Why? Long: I think it has been 20 years since I powered up this VT100 so I did it carefully. Used a Variac and a bench supply. It switched just fine and delivered the steady 5V out when the input was at approx 50V (115V input). All the other voltages looked fine at full AC input. But there was this little smell from R27. Then I plugged everything in and fired it up. Now there were considerable more heat generated in R27 which is a 13W / 1kOhm power resistor. But I still had 4.99V over a random TTL gate on the logic board so the PSU seemed to operate just fine. R27 is part of the snubber network on the primary side of this forward-type SMPS PSU. But why it it getting so hot. Is it normal? I have completely forgotten how a VT100 smell when running... Anyone out there with a VT100 that can put his or her nose above R27 and tell me the temperature? One interesting thing is that DEC apparently did some kind of ECO since my resistor is 1k while the schematic tell me 500 ohm. It doesn't seems to have been replaced. I checked D27 and that one looked fine. Could there be some marginal problem in the circuit somewhere that cause excessive hearing of R27? The primary side looks fairly simple so there are not many components that could fail completely which wouldn't cause complete death of the PSU. C19 is part of the snubber network and is a 0.0033uF 1600VDC film capacitor. Can these go marginal somehow? I never heard of that but maybe? /Mattis

Character ROMs for HP 2631G printer / 264x terminals

by curiousmarc3＠gmail.com

I just resurrected a nice HP 2631G dot matrix line printer: Like here: http://www.hpmuseum.net/display_item.php?hw=316 It has 3 empty slots for extra character ROMs, so I am itching to install some... Anyone has ever made a dump of these character ROMs? Apparently these are the same as the extra character sets ROMs used in the 264x terminal. Math, Line Draw and Japanese would be particularly fun... And French too as a nod to my roots. Marc

Introduction and RK05J Drive cabling

by jnc＠mercury.lcs.mit.edu

> From: Guy Sotomayor > To that end, I've made new "paddle" board that take 2 60pin ribbon > cables. Guy, this is fantastic news! I have previously speculated about doing this, but it's still on the 'someday' list. > I'll let folks know how they turn out (ie do they actually work!). They should. DEC made the same basic part, but using 3x40-pin cables: M9042 (half-length, knuckle-buster) and M9014 (full-length). Apparently the characteristic impedance of N-pin flat cable is close enough to the BC11 cable that it works. Speaking of M9014's, though, the board list describes them as "UNIBUS to 3 H854s", and also lists an M9015, described as "3 H854s to UNIBUS". Does anyone know what the difference is between the two? Unlike the QBUS, the UNIBUS shouldn't need two different kinds of board, since the 'grant in' pin on one end of a UNIBUS cable is the same as the 'grant out' pin on the other end (unlike the QBUS, where the pinout is designed to support plugging in boards, so there are separate 'grant in' and 'grant out' pins). I can't for the life of me think of anything about the UNIBUS that a straight through-connect wouldn't handle - i.e. a pair of M9014's, on each end of the cable set. Certainly, BC11 cables ends aren't marked 'in' and 'out'! ;-) So does anyone know why the M9015 exists - what it different about it, etc, etc? Or was someone at DEC just not thinking hard enough when they spec'd it? > The downside is that they were somewhat expensive Heh, they'll still be cheaper than actual BC11's! :-) Noel

Don't worry about it; BITD we used to run for short periods with the cover off, to calibrate heads, etc. The air-flow through the pack and out the head entrance hole will keep the heads clear. I wouldn't run them without the cover all the time, but for short periods, it will be fine. > From: Tony Duell > The M930 and BC11 should be easy to find, they are actually the same as > the bits used on PDP11 Unibus connections. The second part is correct, but not the first: BC11 cables are now pretty much unobtainium. Noel

VT100 PSU smelling.

by jnc＠mercury.lcs.mit.edu

> From: Mattis Lind > I don't have an capacitance / ESR meter so I cannot check it. If you do a lot of work with analog components (and it sounds like you do), it's probably worth getting capacitance and ESR meters, they can be obtained (new) on eBay for not that much. I have one of each that I got that way; their quality is pretty good, considering how little I paid for them (I didn't think I'd be using them enough to make it worth paying out a lot for really good ones). I haven't used the ESR meter much, but the capacitance meter works quite well, and has been very helpful. Of course, it can't be used in-circuit, but... Alas, I can't (easily) help with the VT100 question! :-) Noel

Introducing myself and VAXstation 3100 help needed

by bryan＠bceassociates.com

Hi Everyone, Jay West was kind enough to point me to this list and I just wanted to introduce myself before I start begging for help. :-) I started out life coding on a CDC Cyber-170 and from there moved up through the TRS-80 model I before finally taking the plunge and purchasing a very early Apple ][+. After that, I moved up through the Apple //e and finally landed in the 32-bit world with my Amiga 1000. I had an Amiga 2000 and then finally sold out and lived in the WinTel world until being "rescued" by a PPC32 Mac Mini. From there it's been Mac mostly but I've always loved older, less mainstream gear. When I rediscovered OpenBSD and the fact that it has some of these "distaff" architectures as full tier-1 citizens, I started playing around. At this point I have that same MacMini (macppc), a Sun Blade 100 (sparc64), an Alphastation 500/400 (alpha), an SGI O2 (mips64), an HP C3700 (hppa) and a VAXstation 3100 (VAX). Everything except the VAX is running 5.9-current on OpenBSD and doing surprisingly well. I'm trying to bring the VAXstation back to life (picked it up on eBay for less than $30 US) and I'm having a problem (here's where I start begging for help). The diagnostic LEDs on the back (thanks to http://home.claranet.nl/users/pb0aia/vax/3100leds.html for helping me decode them) finally settle at: 1000 1010 Which I'm reading as a failed self-test in the "MM" subsystem. I'm assuming MM=Memory Management Unit. I have also noticed it never spins up the hard drive (that's a working drive I personally installed so I know it's good) or tries to access the floppy. On the advice of some of the folks on the list, I stripped the machine down to the bare board (man there was a lot of dust in there). I found (as I expected to) that the CMOS battery had leaked but there wasn't a lot of corrosion on the board near the connector and the solder pads in that area looked particularly beefy so I don't think I have any board or trace damage >from that. When I powered the box up with everything removed, I got the same MM subsystem failure error so I don't think it's the memory board. I'm still waiting on my final cable to be able to get on the serial console so I can't run TEST 50 yet but I'm hoping someone on here can point me in another diagnostic direction. Or, does a failed "MM" test mean the CPU or main board are done with and I need to replace it? Many thanks in advance for any help you can give me. Thanks, Bryan

UA11 Boards have arrived!!

I know some folks sent an email to me indicating their desire for a UA11 board but others may have waited until they arrived. The boards arrived this week (I'm just getting to it because I was out of town on business). They actually got here a week a head of schedule (yea!). The price will be $99/ea + shipping. To make it easy, I'll be using USPS priority with flat rate boxes, so within the USA I'll be charging $15 for packing and shipping, so the total will be $114 (for folks that want more than one board I can probably fit 2-4 boards in the flat rate box so I'll only charge shipping once). I will also be including 1 copy of printed documentation with each order (if you purchase multiple boards in a single order, you'll only get one copy). I accept paypal to ggs at shiresoft.com. If you don't want to use paypal, email me directly and we can figure something out. In any case, please email me to indicate the number of boards that you'd like and where you want them shipped. The folks who have emailed me previously will have priority. TTFN - Guy

Any Collectors in Italy, near Milan?

by robert.jarratt＠ntlworld.com

I am going to be visiting Milan in a few weeks' time. I was wondering if there are any collectors on this list who live in that area, who would like to show off their collection, if I can get a bit of time away from the family? I have a particular interest in DEC machines, but other makes also interest me. If so, please get in touch Regards Rob

Looking for an IBM SP/2 (the supercomputer, not a typo)

by jplist2008＠kiwigeek.com

I was contacted by a guy who works for a computing lab at a major US University on the East Coast who is looking for an SP/2 they can display in their lobby. I have one, but it'll be a monumental pain in the <cough> to get out of here. I wanted to drop a line and see if anyone had one they'd be willing to part with in the US, preferably near-ish to the right coast. Thanks all; - JP

Preferred way of substituting TFT for CRT Monitor?

by Martin.Hepperle＠dlr.de

Yesterday I checked the 9000/217 98204B combo with my oscilloscope and I can confirm the 25kHz horz. frequency (1V down to 0.3V pulses every 40 us). I cannot measure the pixel clock as my oscilloscope was too cheap (I had to compromise) and thus cannot sample at higher MHz rates. I only see that it goes from 1V to approx. 2.2V. Just for my understanding: if I do the math: 512 pixels x 400 rows = 204'800 pixels at 50 Hz I end up with 10.2 MHz and at 60 Hz = 12.3 MHz. There is more "room" required for the retrace time, probably another 10% or so? So I understand that the monitor must be capable of ~25 kHz and 10...14 MHz and that I better try before buy. It is difficult to find specs for these HP 9000 video boards. In case it is useful for someone ... my list below is still missing DIO-bus type (1 or 2) and signal frequencies. 98204B Video Board medium resolution (512x390) monochrome for 35721 monitor, DIO-1 98542A Monochrome Video Board medium resolution (512x400) monochrome 98543A Color Video Board medium resolution (512x400) 16 colors 98544B Monochrome Video Board high resolution (1024x768) monochrome 98545A Color Video Board high resolution (1024x768) 16 colors 98546A/B Monochrome Video Board medium resolution (512x390) monochrome alpha/graphics, for 216/217 display compatibility (a pair of cards, compatible with 2136 and 217 displays (512x390, 25x80)) 98547A Color Video Board high resolution (1024x768) 64 colors 98548A Monochrome Video Board high resolution (1280x1024) high performance 98549A Color Video Board high resolution (1280x1024) high performance 98550A Color Video Board high resolution (1280x1024) high performance 98700A Graphics Display Station high resolution (1024x768) 256 colors 98710A Graphics Accelerator optional for 98700A 98720A High Performance Board high resolution (1280x1024) nur HP-UX, requires 98724AA interface and 98784A monitor 98730A High Performance Board high resolution (1280x1024) nur HP-UX 98722 memory upgrade optional for 98720A Martin

Data Recovery Services

by jcw1231＠pacbell.net

I need to recover some files from a SCSI drive that failed over a decade ago.? Are there data recovery services that can determine if the files on the drive can be recovered or can actually do such a recovery?? Now that I think about it, I recently also had a fairly new Western Digital drive suddenly no longer be seen by any Windows PC and I really need many of the files on it.? Can anybody here tell me if drive manufacturers offer recovery services? I ask this since I saw a post somewhere that Seagate offers some sort of file recovery via cloud storage. As you can tell, I am by no means super-knowledgeable about modern systems since I am from the WANG 2200 MVP, WANG PC, and WANG Basic 2C era, and still have a few pieces of WANG hardware collecting dust. I apologize if I am posting this to a group where it is inappropriate. Thank You, John

HP 2610A printer

by jwest＠classiccmp.org

Someone asked a question about it privately, I researched today and found the answers so I'll post here as well for posterity. The HP 2610A printer that I have.... 2610A was the HP designation for the Control Data Corporation 9322 Printer. HP sold the printer basically unmodified (as far as I can tell) and slapped their label on it. Mine seems to be in rather good condition so I suspect it will be restorable. In addition, I unearthed a full set of manuals/docs for the thing. Most manuals I have are HP ones, but a few in the binder are CDC manuals for it. At the same time, I also found several binders of docs for the HP 2754 (also have one of those). 2754 is the HP designation for the Teletype model 35KSR. HP sold the printing terminal/reader/punch with minor modifications and slapped their label on it. I have a complete set of docs, mostly HP branded but some (wiring lists, lubrication, disassembly, etc.) are Teletype branded. Various select pictures of the manual pages are at https://www.flickr.com/photos/131070638 at N02 J

I will see whether I can use my oscilloscope to catch the frequencies as I could not find a technical description of the 98204B. ... and I thought today such a simple problem could be easily solved with modern technology...

vaxstation 3100 boot issue?

by jwest＠classiccmp.org

I am not a vax person, I'm posting this for someone else. Could anyone offer advice for me to relay back to this person (other than reseating boards, cleaning connectors, or other non-vax-specific stuff)? -------------- I was hoping you could help me answer a question. I have a Vaxstation 3100 that, when I power it up, fails the test with the following LED readout: 1000 1010 which indicates the failure is in the memory management test. Any suggestions on further troubleshooting I can do to figure out how to get this machine booting? My plan is to run OpenBSD on it and see if I can revive some of the ports for this platform. I'm doing something similar on my Alphastation 500/400. -------------- Best, J

I have not yet found the specs for its composite signal. I find many $20 converters/scalers for composite to VGA on amazon or ebay but I am not sure whether such a thing would work for me. Obviously they seem to work for many computer games (SNES, Nintendo) and for some hobby computers like C64, Amiga etc. (e.g. "RCA Composite AV S-Video to VGA Converter Box"). Next I see $50 devices like "Mini Composite RCA CVBS AV To HDMI Converter (Input: AV; Output: HDMI)" which may also be an option, but only seem to scale to a fixed HDMI resolution, which may be unsuitable for the HP-resolution of 512x400 (or 512x390?). Finally I see $200 converters/scalers which are a bit expensive just for trying to see whether they work (e.g. "Atlona AT-AVS100 Composite/S-Video to Component/VGA Scaler"). I have also contacted Jon from the HP-Museum to see what their solution is. Regards, Martin

DEC Rainbow PC100-A

by shadoooo＠gmail.com

Hello, I recently took a DEC Rainbow PC100-A. It has been a huge house for a lot of spiders, who deposited eggs and dead insects all around. After full disassembling, cleaning and reassembling, I'm ready to try it! PSU seems to work well, power goes on with almost precise voltages, then all the test leds on the back will lit on... then nothing happens! No video, no sign of life. Clearly there's a problem at the very beginning of the boot phase, that could be caused by a lot of reasons. In the next days I will try to analyze possible causes of the problem with oscilloscope, in the meantime I'm searching a schematic, as board is very complex to follow trace-by-trace. On bitsavers I found a schematic of PC100B, but the main board is not the same as PC100A. Anybody has a schematic for PC100A? I suspect that ROMs could be damaged, anybody has a correct dump to verify the content of the EPROMS? Thanks Andrea

My TU58 again

by ard＠p850ug1.demon.co.uk

I think I have had a most instructive day. I did what I should have done a lot earlier and connected a (cheap, built from a Velleman kit) DSO to the output of the read amplifier in my TU58. That's pin 6 of the CA3130 at location E28 if you are trying to follow along in the printset, The printset indicates a wobbly waveform there marked 5Vpp. My little DSO can display the peak-peak measurement of a waveform. I started by cleaning the heads and demagnetising them (with one of those mains-powered electrmomagnet things). Of course I unplugged the drive from the controller before doing that in case the induced voltage was enough to damage things. Remember I have removed the 8155 from the controller board and fitted a socket, I have used jumper wires there to start and stop the tape, change direction, etc without the 8085 part getting in the way. I have what appears to be a new TU58 cartridge. With that in the drive I get a steady (and clean-looking) waveform of about 3.6Vpp. Low, compared to the value in the prints, but I suspect high enough to work. Then I tried my console tape. It goes all over the place. Sometimes 4V. Sometimes under 1V. And it is anything but a clean signal. There were times when it was just a little ripple. As I understand it there are no gaps in the formatting of a TU58. Certainly not ones that last for several seconds at normal tape speed. Worse than that, when I put the new cartrige back in the ampltude was significantly lower, around 2.7V. It came back when I cleaned the head again. My conclusion at this point is that my console tape is suffering from major dropouts and is shedding oxide. So now I need to get a good tape (maybe the new one I have), fix the standalone TU58 and dump the console tape image onto it. Or does anyone have any other ideas or comments? -tony

TU58 problems

by ard＠p850ug1.demon.co.uk

I am not sure this fits in with the current topics of this list on the grounds it involves real old hardware, but anyway.. I am currently trying to restore a VAX11/730. I got this about 20 years ago and dismantled it to get it home. For various reasons I never put it back together, I am doing that -- slowly -- now. It's the version in the half-height rack with an R80 at the bottom, then the 11/730 CPU box, and a TS05 on top. I know I am going to have problems with the storage devices, for the moment I am jsut trying to get the CPU running. I've remounted it in the rack, got all the ribbon cables in place, tested the PSU, etc. Minor PSU problems (leaky transistor) but now fine. Powering up gives the expected ROM> prompt on the terminal. Of course all you can do at that prompt is load the microcode from the TU58, so that is what I am trying to get working. And getting nowhere! Firstly the TU58 controller is not passing the self-test. I am pretty sure the 8155 RAM/IO chip is dead. I have removed this and fitted a DIP socket. The rollers were of course dead. I have made hubs and fitted an O-ring of a suitable size. This may not work correctly, but it does seem to move the tape. I have a couple of tape cartridges, the Console microocode tape, and amazingly the belt seems good in them. The motor does get the tape whizzing past the heads. I tried an 8155 borrowed from another device. The controller then passes the self-test (the LED comes on and stays on) but all I get is DD1: Read Error messages and the tape often runs off the spool (rethreading it is something I've got quite good at!). I tried a RS232 analyser between the TU58 and the VAX. Very odd. Either my RS232 anaylser drops 00 bytes or the TU58 sets short result packets. The meaningful bytes (response code, etc) are there, but things like the sequence number are not. Odd... With the 8155 removed, I can pull port pins (on the socket) high and low to start the motor, select drive, track, direction, etc. I've done that and put a LogicDart on the output of the comparator in the read amplifier. According to the manual, the tape is recorded at 800bpi and runs at 30ips. So I get that a bit should take around 41us. And a bit starts with a rising edge, the position of the falling edge (recorded at 1/4 or 3/4 of the bit time) determines whether it's a 0 or 1. Well, sometimes that's what I see on the LogicDart. Sometimes I see a 1:1 square wave with a period of 40-odd us. Does anyone have any sensible ideas as to what to try next. At the moment I have no idea if it's the tape, heads, roller or what.... -tony

In particular, I'm looking for whatever is causing the action in this video to happen: https://www.youtube.com/watch?v=g_LcQ5apODg -- David Griffith dave at 661.org A: Because it fouls the order in which people normally read text.

If it were me, I'd start by setting up some tests to determine what exactly the protocol analyzer is doing. If it really is dropping 0 bytes, then I'd probably hack up a home grown capture using a couple of serial ports. If the controller and the VAX really are speaking the right protocol to each other, then it's time to worry about the correctness of the data. On the other hand, if the controller really is not sending all the bytes it should, I'd check for bit rot in the EPROM. BLS

ISO: Unibus SCSI disk controller

by derschjo＠gmail.com

(...but then who isn't). I'm looking for a mass-storage device for my PDP-11/44, and I'm having worse and worse luck with my current solution, an Emulex SMD controller -- drives just keep going south on me (the controller works fine, though...) I know how hard these things are to find, but if anyone has a Unibus SCSI controller they're willing to trade for something else, let me know. I have a variety of gear, PDP-11 and otherwise, drop me a line and maybe we can work something out? Thanks as always, Josh

Need cheap source for anti-static chip tubes

by snhirsch＠gmail.com

Title says it. Perhaps I'm being stupid about search terms, but I'm not finding much of anything on eBay. One seller has TSOP tubes, but I need plain, old 300mm DIP tubes. End plugs and pins for them as well. Plenty of companies offering them on the web, but all are oriented for production quantities. I'd be happy with 20-25. --

TU58 problems

by shadoooo＠gmail.com

Hello, well, if you see square waves, probably the read path analog circuit could auto-oscillate. This could be because of poorly filtered supply (bad electrolytic capacitors), or possibly some component in the feedback that's not soldered well. I should have a schematic around, I could give a look tomorrow... Andrea

My last word on building computers!

by c.murray.mccullough＠gmail.com

I?m not sure to what degree one can/wish to build there own car. If one puts their mind to it; then anything is possible. I?m sure this applies only to die-hard builders and not representative of the ?average? guy/gal. One, and I may be stereotyping here, does not have the time to build much of anything is this hurried world we inhabit. I know this website caters to the experimenter/hobbyist in the computing world but I wonder how many of us have the time/inclination to build an old machine. I recently tried to revive my Coleco ADAM but couldn?t find old capacitors/transformers ? maybe in America they?re available! (I could run an emulator on my PC/Mac but to what end? It?s definitely not the same as running the real thing is it?) As for new machines I guess there are builders /programmers of Raspberry Pi?s but they have a limited use for power users and for ?old? computer aficionados of classic computing era! Do young people want to do this? They may be computer savvy but I don?t think too many have an interest in building anything, particularly from the vintage era. My friend?s grandson, he?s 7, told me the computer is a tool for getting ahead not for looking back. Yikes! Happy computing! Murray :)

Archiving CP/M 2.2 Source Code Programs to a PC (Fat or NTFS media)

by robo58＠optonline.net

Hi Folks, I have many diskettes worth of CP/M 2.2 assembler source code and programs that I'd like to archive in the PC environment. I'm worried that my media is degrading and I want to move it before it's too late. The media is mostly 8" SD or DD, there are also some 5.25" HD diskettes too. I have the original hardware and can view the media and run the programs. I'm looking for suggestions on how to move it to the PC environment. Thanks Robo

Archiving CP/M 2.2 Source Code Programs to a PC (Fat or NTFS

by f.heite＠hccnet.nl

>>> From: Robo58 <robo58 at optonline.net> >>> >>> I'm looking for suggestions on how to move it to the PC environment. IF your CP/M machine has a serial interface, I would connect it to a serial interface on your PC. Then use programs/protocols like kermit/xmodem/ymodem/zmodem/procomm/telix/hyperterminal to copy your CP/M files to your PC. Which one to use, depends on what software you have available on your CP/M system. On the PC side, you'll probably always be able to find a corresponding program. Have fun, Freek.

Building a PC - then & now

by c.murray.mccullough＠gmail.com

I was reading in a dated magazine article on the "freedom to build(a PC)": Well you can't build phone; can't build a car; can't build a refrigerator; can't build a TV. Do we have the freedom to build a computer? We did in the earliest days of the PC- the 8-bit era. Heck, that's all one could do! It was limited and is to this day. AMD vs INTEL control what we can do. Has anything really changed? Happy computing. Murray :)

USO (Unidentified System Unit)

by jnc＠mercury.lcs.mit.edu

> From: Henk Gooijen > I could not find the M5950 nor M3020 in any module list. The M3020 (and M1131) are variants of the M302 (and M113, respectively), so I don't think those are much of a clue. The M5950 I couldn't find anything about at all, but the M595 is a current mode converter for the DF11 - which I can't find much about, although it's in the '73-'74 Peripheral Handbook - but that looks distinctly like a possibility, from the pictures there.

Archiving CP/M 2.2 Source Code Programs to a PC

by mark＠markesystems.com

From: Jon Elson <elson at pico-systems.com> > Got a console serial port on the CP/M system? You should be > able to use a program like Kermit to suck up the files. Something like this was going to be my suggestion, too. The original request was to archive the source files, not the disks themselves. Virtually every modem-type program (MODEM7, for example) has at least XModem, and of course there are tons of options for the PC end (PuTTY seems to be a popular choice). Hopefully there's some serial port in the system, even if it's not the console. And you do remember how to write 8080 code and make CP/M calls, right? Worst case, since it's "Source" you're trying to archive, would be to write a simple program that just reads a file and blurts it out the serial port, with no handshaking at all. Running a serial capture on the PC would probably have very few, if any, errors. ~~ Mark Moulding

Sun SPARC at iBid State of Illinois auction site again

by jzatar2＠illinois.edu

Hey everyone, I was browsing and I noticed that there's another Sun SPARC posted up: https://ibid.illinois.gov/item.php?id=170591 last time, I think there was one that went for a mere $5. Now of course, you gotta move it or pay to have it moved, but if you're interested, act now and start getting an account on the site. When I got my account, I had to wait a few days before they actually got my account set up. Anyway, given that this is the second time I've seen Sun equipment on the site at the same location, I would venture to guess someone over here in IL government is phasing out their sun stuff, so maybe it's worth checking in the future as well for more stuff if anyone's interested.

I COULD JUST KICK MYSELF IN THE BUTT!!! commodore pet . . .

by tulsamike3434＠gmail.com

Back in the mid to late 90's I used to go to the Salvation Army store every day before work because I worked night shift and the lady at the counter used to have a crush on me and would set aside all old computer stuff for me. Well one day I went in and I seen her wheeling me out a Commodore PET with the calculator keyboard witch drove me insane trying to program on that lil keyboard lolol. I got it for 10.00 FREAKING BUCKS yes TEN F.R.E.A.K.I.N.G. BUCKKKKKSKSKSKSSKSKS}{PJDGHLGFO GRRRRRRR Sorry about that I almost just broke my keyboard just telling this story lol anyway I played with it and this was just before AOL went from 20.00 for 15 hrs of INTERNET time to 19.99 unlimited net time. I don't know if any of you remember when they switched over to the unlimited monthly plan but as for in Oregon AOL Servers crashed for about 3 months from such a heavy load of members dialing up and connecting quick question here _*<------- Did this happen in your area if so where were you?*_ Anyway back to the commodore PET I snatched that baby up and most of my information I got for older computers back then was the library I used to spend HOURS AND HOURS reading and learning how to program in BASIC I had no idea what all the ports in the back were for I was just happy to have the built-in tape drive. I was programming a " ROCK n ROLL TRIVIA GAME" boy I got in such big trouble because Cd's where the new thing then so I had no blank tapes so I remember I got busted from my mom, She was so mad at me because I use a TAMMY FAY BAKKER from the Jim Bakker PTL show tape in my Commodore PET Computer lol Well just about this time all the "TREE HUGGER'S" Were using the SPOTTED OWL to bring the logging industry to it's knees! so about that time a friend of mine from central America and offered me a job in the Oil industry and I up and left everything behind but I must admit a year before that my Mother bought me my first PC it was a Amega 486 DX66 with 8meg of ram and I was getting very interested in HTML web programming I think my first FREE HOSTING website was on GEOCITYS. ANYway I hate myself for leaving my MINT condition Commodore PET when I moved but I had alot of other life choices to be dealing with at the time...

DEC PDP-11 software manuals available

by jnc＠mercury.lcs.mit.edu

So I have a bunch of DEC PDP-11 software manuals which I don't want (which I got in a lot with some other manuals I did want). They are free to a good home (US media mail free, anything else we'll have to work out). They are: RT-11 Documentation Directory (AA-5285D-TC, March '79) RT-11 System Release Notes (AA-5286B-TC, March '78) RT-11 System Generation Manual (AA-5283B-TC, March '78) Introduction to RT-11 (DEC-11-ORITA-A-D, August '77) RMS-11 Installation Guide (AA-H235A-TC, June '79) RMS-11 User's Guide (AA-D538A-TC, March '79) RMS-11 MACRO-11 Reference Manual (AA-H683A-TC, March '79) Also, before I send them off, should I scan any/all of them (I'm too lazy to look to see if they already available online :-)?

Front Panels - Update

by rodsmallwood52＠btinternet.com

Hi Guys I just had an email with some pictures of the panels in. The panels are great but the pictures not. Because you need lots of light to see what you are doing. They have several skylights and the light is all wrong for phone cameras They are adding the final details : A and B customisation and the second white line round the lock area. The front is now matt black. I'm changing to professional packaging as green tape and cardboard works but is not that pretty. So we expect to start shipping when the new packaging arrives. PDP-8/f and /m are waiting to be screen printed next. PDP-11/XX are being drawn now and I'm going to try and have at least a few boards ready with the common features before taking orders. Rod
