Okay thanks. ?I gues where I'm getting confused is Michael Holley's guide to new 6800 users says because of the 6810 being cut you want RAM at $A000.. what you're suggesting sounds like the opposite? ?Maybe I'd better reread those instructions.

I could config the second DRC board for the > $Exxx-$Fxxx and shove it in there. Don't take my word on the specific address, I should have just said you need some RAM in high mem. The 6810 was there to fulfill that need of RAM for the xxxBUG monitor. You might reenable it, or config a RAM board to cover that range (A000? to ?). But if you use a RAM board you have to config it so it doesn't extend up into (overlap) the ROM and IO address space. (I have a memory map for this on another machine not set up at this time). (For purposes of exercising the xxxBUG monitors you don't need memory down at $0000.)

SWTPC 6800

by vintagecomputer＠bettercomputing.net

Yeah to be honest.. I'm not sure I'm the biggest serial terminal computer fan. ?I find them way harder to diagnose than computers with video cards. ?But, the SWTPC is an iconic system.. so I'll just keep muddling until I figure it out.

If and when you get consistent characters, no matter how wrong, then it's time to look at the bit patterns of what you get V what you expect? (is anybody around who knows?) Since, obviously, if consistent, then it might be right except for one or more bits stuck on or stuck off. Yes, it is frustrating.

SWTPC 6800

by vintagecomputer＠bettercomputing.net

Thought I would post this here in case it reaches eyes my forum posts don't. ?So I finally got my hands on a SWTPC 6800! ? This machine is chock full of boards.. 4 ram boards, the cpu card (with SWTBUG ROM), MP-S, MP-C serial cards, a floppy controller, some little custom board, a sound card.. etc. This presents some challenges obviously, since the machine has been altered from stock it could be tricky getting it running. Before I had it stripped down, I tried powering up as is (i pulled the older MP-C card and put MP-S in slot 1). ?This produced little except for a string of random characters that would repeat every time I hit reset, exactly the same number. I tried stripping it down to CPU card, MP-S, and the RAM board designated as '0'.. but all I get at the terminal end is a single random character on power up. ? I then thought I'd try my luck putting the CPU card in my working MSI system (taking out its card). ?Nope. ? Now, because my CPU card has been modified to accomodate SWTBUG and possibly something else, I'm not sure if it'll even work in a stripped down config. ?Not sure about the interplay between boards. Anyway.. if anyone has any thoughts to point me in the right direction I'd be most appreciative. ?Ultimately I'd like to get this beast working with my CT1024 terminals.

Tektronix 6800 'Developer Computer'

by vintagecomputer＠bettercomputing.net

Hey guys, In addition to that 6800 SWTPC I got, I also picked up this 'board bucket' >from ebay: http://s1381.photobucket.com/user/unclefalter/library/Tektronix%206800%20Dev eloper%20Computer?sort=3 <http://s1381.photobucket.com/user/unclefalter/library/Tektronix%206800%20De veloper%20Computer?sort=3&page=1> &page=1 It's a 6800 system of sorts and has BASIC and 'DDE' ROMs. I've tried hooking it up to a terminal but no response. I think the system isn't fully running. This is a video I took: https://www.youtube.com/watch?v=7YSUuF6xTAg Hard to see with the camera, but when you hit and hold reset the little display looks sort of normal. When you release, it's like some of the segments are half-on rather than fully on or off. I tried pulling RAM boards and such but no action yet. Step button on the CPU card doesn't do anything. If anyone has seen one of these or has any ideas on getting her working, I'd be most interested. I sent an email to Tektronix to inquire about it as there are part numbers and stuff on the boards. Hopefully they can answer questions. Brad

VCF books (Was: Is MS-DOS, PC DOS and DR-DOS vintage enough

by cctalk＠ibm51xx.net

I don't know about using eBay as things are all over the place. I have paid from $0.99 + s&h to $29.99 w/ free shipping (for something that is useful e.g. HMS for 5150 in unopened condition). My average seems to be $9.99 for more popular stuff and $4.99 for esoteric stuff (say GTO to the 7327 plotter). Every once in a while things sell for crazy prices (do you really need the TR to the cluster network for $90?). What sells high seems to be SW specially DOS 1.0 and IBM branded CP/M. Those are fetching >$500 these days. Just my two cents.... -Ali

Is MS-DOS, PC DOS and DR-DOS vintage enough to count?

by lproven＠gmail.com

I'm experimenting with some old DOS versions, notably PC DOS, in VirtualBox. I have a PC-DOS 2000 system with DesqView and DesqView/X working fairly well -- no networking yet but I'm working on it. I am also trying to get a DR-DOS 8 VM up and running. DR-DOS 7.03 is no problem, but I've had no joy getting DR-DOS 8.1 to install to hard disk. It's reluctant to SYS a hard disk, and when it did, it mis-diagnosed it as FAT-12 and wouldn't boot. Using Norton DiskTools, I've managed to transfer the system files, but they display the message DR-DOS 8.1 ... and then it freezes. Can this late version, mainly used for utility floppies, actually boot >from HD & be used like a normal DOS? And although I've not tried it yet, the same question applies to PC DOS 7.1, the early-noughties version that can understand FAT32 and long filenames. -- Liam Proven ?

Bill Gates: Windows 95 Was 'A High Point'

I would call Win 95 a high point also. ?I lived near Toronto at the time and remember the unfurling of a huge Win 95 banner down one side. ?There were events everywhere. ?MS was really at their zenith.

SWTPC 6800

by henk.gooijen＠hotmail.com

Sorry list, now trying top post ? somehow my typed tekst goes into a bit bucket. Back in the seventies (well, 1979-1980) I had a 6800-based modular system in a 19" rack, 3HE high. One Euro-card was the 6800 CPU, another Euro-card was 8k RAM ("famous" 2112?s IIRC), one Euro-card with 8 sockets for 2716 EPROMs. Plus a self-made cassette interface. I still remember buying two 2716 EPROMs for 313 Guilders! That was a lot of money for a poor student! Two years later I bought a generic floppy disk interface and 5.25? TEAC FD50 floppy drive (SS/SD) and wrote my own ?DOS?. Took 8 months, but I no longer needed the cassette interface. A small bookshop in Amsterdam (Computer Collectief) sold great books (at that time) for the real hobbyist. That way I got the TSC Editor, TSC Assembler, TSC Linker and TSC Debugger. And it all came with source listings, so I could hack away my own interface routines :-) With the TSC software I developed my first StarShip assembler code. It was some 10 to 14 files which you assembled to "relocatables". Subsequently you used the linker to create the "absolute" from the relocatables. Worked really well. Those were the days! I still have the 6800 system, Build-It-Yourself keyboard and monitor. I wonder whether the EPROMs would still have all bits OK, after 35 years. Fond memories, - Henk PS. I have a 6800 source listing of StarTrek, not sure that came from TSC!

Yes thankfully the previous owner labelled everything. ?The cards seem to be in great physical shape, however the motherboard does have a bit of corrosion here and there. PSU checked out ok in preliminary testing. The CPU card appears to be set up for Flex.. the expected jumper is cut and it looks like the 6810 onboard is bypassed. If I read Michael Holley's guide right that just means I need my first RAM board configured as '0'.. but that was the case already.. not sure why that would ever not be the case.

For example the MP-S has baud rate setting options, and the card can be used with a Teletype or RS232 terminal.? 1200 is max baud. If you're getting a consistent but garbled output to the screen did you confirm the baud rate you're using matches the MP-S jumpers?

Random stuff in Belgium

by jon＠jonworld.com

All, I was surfing our local website which is essentially "Belgian Craigslist" and found some vintage ads. I'm curious about this and too lazy to google on my own. It looks like these are Sony PCs with robot arms which can be controlled? http://www.2ememain.be/informatique-jeux-vid%C3%A9o/bureautique/286-et-plus… He's about 50-60km from me if someone wants/needs me to snag anything. If there is other stuff around here you're interested in, please let me know. -- -Jon +32 0 486 260 686

HP 2100A Restoration

by perlpowers＠gmail.com

Hi, I recently acquired a pair of HP 2100A minicomputers locally for very cheap. Don't think I could get much more local that a guy literally at the end of my street. He bought them at an auction over ten years ago, never powered them on, and left them in his garage since. They've likely never been powered up since they were last in regular use. The units seem to be complete, apart from missing a few I/O cards that are written onto the top of the power supply. I don't plan to power them up until I've taken them apart, cleaned all the dirt and debris from them, and inspected the power supply. With regards to the power supply, I'm thinking my best bet would be to do a power on with no cards in the system. Though I'm not sure if all the power rails would even come up without a load on it, since it sounds like it may do some power sequencing from what I've read. I was wondering if anyone has some experience with testing a similar power supply that hasn't been run in at least 10 years? I'm not sure if using a variac to slowly warm up the supply and the caps would be wise on one of these power supplies. I'm not sure how the switching supplies would handle the low voltage at the start. The only I/O card that was installed in both machines, besides a terminator board in only one of them, is a serial interface made by some company with the logo CMC. It uses a COM2502 UART which I was surprised to find a datasheet for, however I haven't found any information on the card itself. I have a photo of the card in the album linked below if anyone has any information on it. I know this email is getting a bit long, but with regards to the memory both machines have a ID(16K) driver board, and two core modules. However one machine has both core modules marked 02100-60052 on the bridge, and the other has one marked 02100-60052 and the other 02100-60054. Is there any difference between these modules? I'd assume by the 16K driver in both, that all of the core modules are 8KW modules. Would that just be a later revision or is one a different size? I've taken some photos of the machines and put them here: https://goo.gl/photos/z2tGBbNvekwrxS5L9 I'll be taking more after I make some space to start taking the units apart for cleaning and inspection. I've also included photos of the serial numbers and other badges on the backs if anyone knows of a resource to decode them. I'd very much appreciate any help or suggestions that people have. I really want to get at least one of these machines back into full working order to have some fun programming with. Thanks, Hayden K.

Irix 5.3 drivers

I realise this is a bit of a long shot, but does anyone have the driver CD "GIO Fast Ethernet 1.0 for Irix 5.3 and 2.0 for Irix 6.2", SGI part number 812-0576-001? This is the drivers for SGI's own Fast Ethernet card, not the Phobos/3Com ones. -- Pete Pete Turnbull

8 inch disks - help needed identifying format

by denise.devries＠flinders.edu.au

I am trying to preserve data from a selection of 8inch disks and the only information I have is some printouts which I believe to be HP CAT reports. The first couple of lines are as follows NAME PRO TYPE REC/FILE BYTES/REC ADDRESS H8,0,1 148 ALT-A DATA 1 1188 0/1/0 Can anyone answer the following questions? Is this an HP CAT report? What does the H8,0,1 mean? Is it likely that there are 1188 bytes/rec? What does the address 0/1/0 resolve to? Any information would be most welcome Denise de Vries ________________________________

Rich - correct. That is the disc we have here. Just wondering in case We ever got a pdp-8 with disc interface or a standard unibus PDP 11 here at SMECC .

Differences between the PDP-11/15 and PDP-11/20

Oh, right you are - I hadn't worked that out. (Probably because my head is still full of KT24 stuff, which doesn't have two totally separated busses. :-) > That assumes the KT11-B does only memory mapping, not the other things > that other MMUs do (user vs. kernel mode, I/D space .. ). I don't think it can; those would require hooks into the CPU, and there are no signs of such, in the pictures. Noel

The only point was to mention that if some systems have issues with SCSI drives due to their capacity alone you can usually soft resize the drive smaller. No need to pay a premium for older SCSI drives of 1GB native capacity or smaller.

Differences between the PDP-11/15 and PDP-11/20

by jnc＠mercury.lcs.mit.edu

> From: Steven Malikoff > I'm wondering if there are any more differences apart from the lack of > the two high address switches? According to the -11/15-20 processor manual (pg. 2), the differences between the two are i) the -15 has only one hardware interrupt level, not four (the latter is optional), and ii) power-fail restart is an option, not standard. > Presumably the /15 could not run one of those KT-11 paging units I'm not sure how the KT11-B works, but my _suspicion_ (going from the pictures of that one that sold on eBay) is that it's not part of the CPU, but a UNIBUS device, which maps part of the UNIBUS which the CPU _can_ see (i.e. in the 0-56KB range) up to higher addresses, where the 'extra' memory is configured. If that supposition is correct, it would work equally well on any -11 (without built-in memory mapping in the CPU). Noel

Differences between the PDP-11/15 and PDP-11/20

by steven＠malikoff.com

A few months back you might recall the road trip I did to recover a Foxboro FOX-2, a rebadged PDP-11 that ran the furnace oxygenation plant at the BHP steel mill at Port Kembla here in Oz during the 1970s. I had thought the machine was an 11/20 with a custom FOX front panel that (apart from the Foxboro lime green colour trim) had only 16 address switches instead of the 18 found on that machine, and that there might be two more vacant switch locations on the front panel PCB to be found lurking underneath when it came time to disassembling. But having just seen the PDP-11/15 up on eBay, I now believe that is what the FOX-2 really is. This page (http://gunkies.org/wiki/PDP-11/20) reckons the /15 is just an OEM version of the /20 but I'm wondering if there are any more differences apart from the lack of the two high address switches? (Presumably the /15 could not run one of those KT-11 paging units as was seen on that recent eBay 11/20) Steve.

PDP-8 _Introduction_to_Programming_ & _Programming_Languages_(Scanned) Covers Needed

by bobvines00＠gmail.com

Does anyone have DEC's PDP-8 _Introduction_to_Programming_, Editions 3 and/or 4 and/or the PDP-8 _Programming_Languages_ handbooks? If you're not willing to part with your copy, could you scan the front covers of these handbooks and tell me which Edition(s) they are from? I'm especially looking for the front cover that had the "format generator program" printed on it in the background. I'm also looking for DEC's PDP-8 _Programming_Languages_. If you are not willing to part with them, could you scan the front cover and tell me which Edition(s) it/they are from? Thanks, Bob

MicroVax II

by dj.taylor4＠comcast.net

I just got a MicroVax II in the BA123 world box chassis. I has a TK50, RX50, RXDQ2, but no DEQNA. I'd like to get it running an OS. The DU disks don't work, but I have a couple of Qbus SCSI controllers that might come in handy. Can you use those SD to SCSI convertors in this type of configuration? Anyone have experience with this? What OS's can I use with this hardware? NetBSD? Are versions of VMS available? How do you get an OS onto this system?

Is MS-DOS, PC DOS and DR-DOS vintage enough to count?

by jnc＠mercury.lcs.mit.edu

> From: Chuck Guzis > I routinely use Win98SE for my DOS tasks--it boots into DOS quite > nicely if you edit the MSDOS.SYS file to say BootGUI=0. That's considerably more elegant than the way I use, to get my 98SE boxes to boot into DOS to start with (which I prefer, in case I want to do anything that requires Windows not to be running, e.g. disk repairs); I just re-named 'WIN.COM' to 'LOSE.COM'. So I get an error message grumbling that it can't find WIN.COM, and then it falls into DOS. Of course, my way, I do get the ineffable pleasure of saying "LOSE" to start Windows, every time I boot the machines. Never gets old. Noel

If it is I can dump the EPROM firmware in mine for you. Maybe two EPROMs for 16-bit wide firmware. Responding to my own previous post. First, it is a TTi QTS-3, not QTS-30. The plain dual wide version without the S-Box handles is the QTS-1. Second, I can confirm that the CSR address is configured through the 10-pin serial port. Last, there is a single firmware EPROM. The other 28-pin socket is an 8KB SRAM. A Fujitsu 8464A on one of my boards and an Inmos IMS1630P on the other. Any standard 8KB SRAM of same or better speed (didn't check the speed grade) would likely be fine.

Tek 4025 and 4017 Terminal option 31 kit to give away

I was rooting through the drawers in the shop looking for some torx screwdrivers and I found a Tek 4025 option 31 field upgrade kit part # 18-0124-00. This is complete in its original beat up box and useful only on a Tektronix 4025 or 4027 graphics terminal and there are none of those anywhere near here. Option 31 is a character set upgrade kit and has a printed circuit board, two character set ROMs, a DOS 5-1/4 floppy disk containing who know what, and a ribbon cable. And instructions. In the box, but unrelated, is an NIB key for a keyboard Tek part # 260-1924-00 and a used key cap (from a 4025?) labelled ERASE. Anybody want it for the postage? It should be fairly cheap to mail. -- Richard Loken VE6BSV, Systems Programmer - VMS : "...underneath those Athabasca University : tuques we wear, our Athabasca, Alberta Canada : heads are naked!" ** rlloken at telus.net ** : - Arthur Black

I am happy with 10 just a few things to get used to. upgraded the edit bays and office systems... all is well no urge to go backwards.... In the archive area we keep at least one... dos 6 3.1 95 98se xp vista 7 In a message dated 8/1/2016 5:35:59 P.M.

Concurrent Computer Corporation

by pontus＠Update.UU.SE

Hi I'm trying to revive and old unix machine. A Concurrent Computer Corporation series 8000. This seems to be a later version of Masscomp MC5600/MC5700 which has a manual in bitsavers. The system runs RTU (which I assumes means Real Time Unix). My machine is in great condition and both SCSI disks (Seagate ST516) seems to work fine and I've made images. But the machine panics at boot: --- panic: Unauthorized use of RTU For further assistance, contact Concurrent's Customer Service Technical Support Group --- The NVRAM battery is long dead and upon entering the console I get a complaint regarding the TOD clock, but I see no way of setting it. I can boot into a "stand alone mode" but not single user. In the SAM I can poke arround the filesystem and use "date" to set a date, but the clock appears not to be running. Does anyone have experience with this type of machine, either CCC or masscomp and can offer assistance? It's a dual MIPS machine with 16MB of memory. /P

Copyright act Section 108

by jwsmail＠jwsss.com

IANAL, and this is way off topic, but needs to be put out as there are a lot of ears here that depend on Bitsavers, and probably some of the other Museums. The Copyright office seems to be unhinged with an unrelated matter I won't post here (email me off list if you don't know about it), and is looking at things with a bad eye towards messing things up. This is the Section 108, which probably protects libraries and archives who have the need to allow copies of works made. Bitsavers has a slight off center of that charter in that they collect stuff in a different way than libraries do, but once collected it probably enjoys the protection of this part of the Copyright act. Almost everyone sounds like they are puzzled why it needs messing with, and probably does not. But we should be alert that collateral damage >from some idiotic revision doesn't include Bitsavers, Boatanchor, or countless others. Manx? Thanks Jim https://www.techdirt.com/articles/20160729/23591535111/copyright-office-int…

Bill Gates: Windows 95 Was 'A High Point'

by vintagecomputer＠bettercomputing.net

Never did try OS/2. ?I had friends who were fanatics about it. ?There was a big push back then to go to it. ?When that failed they rallied to Linux. ?Really should set up a box here with it and try it out.

That was OS/2 2.0 for me, after I had settled into OS/2 1.3 Unix took me longer to warm up to. Jerry On 08/ 1/16 07:29 PM, Brad H wrote: > > > I would call Win 95 a high point also.

Midwest Scientific Instruments 6800

by vintagecomputer＠bettercomputing.net

Just thought I'd send out another shout out to anyone who might have one of these or is familiar with them. ?I've had this a while but have not really been able to use it, lacking a boot disk. ?It also doesn't have the standard MSIBUG ROM. ?I'm hoping maybe someone out there knows how I could procure the original ROMs and put this back to stock. I made a video showing the current 'WEEBUG' ROM in case any are curious or someone out there knows about it. Thanks! https://youtu.be/LY7yoAVxSrM Sent from my Samsung device

MicroVax II (Doug)

by grahamcreid＠gmail.com

The company I worked for in 1989 had three hand-me-down MicroVax II from the US parent. They were originally a PDP11/73 box, which had been converted. They ran VMS 5.5-2, all had DEQNA, with no problems that I remember. They were just networked, it wasn't a cluster. The DEQNA may have been *unsupported* on 5.5, but it seeded to work OK. I still have one system, and bits of the others. Failing ESDI drives put them to the back of the garage. I do have a replacement ESDI drive, and a Q-bus SCSI controller, so when i get time (ha!), I'll resurrect it. Regards, Graham
