Well, dang it... I'm running out of room, and I really don't have the time that this gorgeous old beastie deserves, so.... Here's what I've got. A complete H89 system as follows. System unit with internal FD -- no screen burn that I can see, very clean. External dual FD. (all FD's are 5.25" hard-sectored 40 TPI). Cassette I/O board. OkiData Microline 82 series printer. IBM "Plug-and-Play" EPROM kit for the OkiData, something about 'Block Graphics.' Extra printer ribbon, still in the shrink wrap. Spare chips: 4116-25, 74S132, and 74LS186. PROMs (Heath/Zenith part numbers on the labels): 2 ea. 444-43 EPROMs (a pair of 2716's, also with H-Z part numbers on the labels): 444-40 That's the hardware. About the only thing that's missing (God only knows why) are the hardware manuals. I do have the following software for it, with manuals. CP/M-80, Ver. 2.2, Heath-Zenith tagged. 'Ed-a-Sketch' graphics editor. 'Reach' modem and file transfer program. PIE 1.5 full-screen editor. HUG Utilities and BASIC-E disks. NewWord Word Processor, ver. 2.17 JRT Pascal, V. 3.0. Space Odyssey 1 Microsoft BASIC Compiler on original 8" diskette, ver. 7032.530 Spare diskettes (at least a box worth). Please to make me an offer on the whole schmeer! I know I can trust you lot to make it a fair one. It would probably be best if said offer came >from someone local (Seattle, Portland, etc.). I can ship the stuff, but that could get costly even with UPS Ground. Some of the units are pretty heavy!

Sparc Supply Schematics

by karlm＠blitzen.canberra.edu.au

I have a friend who has 6 Sparc SLC's with either dud power supplies or monitor sync problems, is the schematics for the power supplies available easily? Not having looked at them myself, I would expect that they are a standard SWPS, also would anyone know the voltages and pinouts for a sparc supply, it is probably possible to mod another kind of supply to fit :) Thanks as always :) Karl ------------------------------------------------------------------------------ Karl Maftoum Computer Engineering student at the University of Canberra, Australia Email: k.maftoum(a)student.canberra.edu.au

Tandy Keyboard

RX50's on a PC?

by aaron＠wfi-inc.com

Has anyone tried wiring an 8" RX52 floppy straight to a modern PC controller? I did the best I know how, and I *appear* to have a semi-functioning device attached. Trying to read/format the disk >from Linux causes the drive to access; however, trying to format (even with PUTR under MsDOS) gives me a verification error and an error about Track 0. Does this sound more like a media error? The disks (Dysan 101/1) appear to be in fine condition, having been stored in rigid notebooks in plastic sleeves for the last 10 years or so in a "media-friendly" environment. There are also lifecycle logs in the sleves, which indicate that they were initialized and only written to once. I've been digging around, trying to get enough information to attempt to set up Forth on my OS-less 11/23, but I don't have another functioning system to work with (the chicken and the egg). Am I dreaming that I'm going to be able to get anything accomplished with an emulator and a pair of 8" floppys Frankensteined to my PC? On a similar note, does anyone happen to have a Compaticard for trade/sale? Aaron

Which jumopers? > Still no luck otherwise though. Acts the same when I try to boot. If your ROMs don't support RX33s, there are two problems that may prevent the RQDX seeing the drives as usable. First is that an RX50 responds with a READY signal as soon as it's polled, if there's a disk in it, because the READY signal is really a "disk in" signal from a set of contacts. Most drives respond with READY only after the disk is up to speed, since the signal is derived from the index pulses (the original meaning of the READY signal was that there is a disk in, and it's up to speed, as determined by measuring the time between two index pulses). The 200ms (minimum) delay prevents the RQDX seeing the disk. Second is that on an RX50, the SideSelect -- which isn't normally used, since an RX50 is really two single-sided drives -- is used to disable the TrackZero output. The RQDX tests for an RX50 by stepping to Trk0, checking the output, setting the SideSelect, and checking that the Trk0 signal has gone away. I guess these tests are probably because the RX50 shares some signals with the RDxx drives on the same distribution board. I have two or three Canon and Mitsubishi drives modified to work like this, and they work fine on RQDX2s and 3s. Unmodified, they don't. In fact, now I think about it, I have a feeling those drive "fixes" are needed for the 243/244 ROMs as well. -- Pete Peter Turnbull Dept. of Computer Science University of York

I'll presume you mean the rather large dual drive RX02. The DEC 8" floppies are RX01/2 and have their own internal controller. That would make RX01 or 02 disk system very hard to wire to a PC floppy controller, like near impossible. FYI: The DEC RX02 DD format is not readable by any standard floppy controller chip. RX01 however is standard 128 bytes IBM softsector format. RX50 drives are fairly easy to wire to a PC it is however single sided and dual drive with one spindle. The later item will cause all mannor of errors if the driver doesn't internally know the two drives have a common positioner.

DEC Rainbow

by cdrmool＠interlog.com

I just grabbed a Rainbow out of the garbage with the garbage truck literally meters away from getting it. After major industrial cleanup (removing the half gallon of house paint from it and the cigarette goo), Its up and running mostly. It came with the MS-Dos 2.05 OS, some manuals, and thats it. I know diddly squat about this beast (other than the legend of it possessing two CPU's) and CP/M. So this is a very basic question. When I get to the menu at boot up it recognizes a: and b: (though a: is a bit wonky). It will also respond to W which tells me that there are two cp/m partitions: e: and f: however, when I try to go to them I get a "message 23 - Non-System Diskette". I seem to be missing the manual with numbered error messages. I'm assuming that this means that there is a hard drive problem. However, it is recognizing the partitions so something is being read. I also don't have the CP/M diskette, only the DOS. This DOS doesn't have FDISK so I can't look at the partitions via an OS I know well (though I could do it through debug but I'm being lazy here), and when I bit the bullet and tried to format the hard drive it keeps telling me to stick in the diskette to format. Any help would be appreciated otherwise I'll do a low level format on the segate drive and pray to the appropriate dieties. Colan

Tandy Keyboard

Hmm... I've had this problem from time to time with Pine (a well-known but in some respects very iffy UNIX mailer) and with other mail software based on similar library code (elm, and a new GUI one whose name escapes me). The author of the library made some unwarranted assumptions about what exactly are the rules that govern separation of messages in a mailbox, and the allowed formated for the date, with the result that messages sometimes get stuck together. The author forgot the adage "be forgiving in what you accept and strict in what you transmit".

The purchaser bought it only to trade for an original 8800 which he has done. It will be interesting to see what happens with these 680's currently up for auction.

Actually, those Eagles you have are 10.5" drives. Earlier Fuji's, like the 2281/82/83/84 series, were 14".

PROM Burner

by jolminkh＠nsw.bigpond.net.au

I have found an ancient PROM burner, a Data I/O System 19, with a Unipac module fitted. Test stickers on it are dated 1980. It came with an "Operators Synopsis" with which I am totally out of my depth and a wall chart dated 1985 with details of PROMs of the day and which Unipak revision applies to which. ?????????? I had hoped to be able to use it to back up older ROMs which my circa 1995 EPROM programmer can't handle. Is it usable for this? It has a serial type connector but no software (it predates the PC). There is an LED and a hexadecimal keyboard. It looks like it was meant to be used manually !! Typing stuff in character by character. There's nothing on Data I/O's website about this and they haven't replied to my email as yet. Can anyone offer advice? Thanks Hans

Tandys gone/Apples anyone?

by backofene＠hotmail.com

We're located in northern VA, 7 miles from DC. The challenge is to get the old stuff in the hands of those who want it so it doesn't wind up in landfills. We used to have "yard sales" to clear out the old stuff, but I got tired of answering questions/complaints months later from people who bought an entire system for $10, so eventually we just set the stuff out and let any interested people take it away. With our student population increasing, we're using every available space as classrooms. Write me at backofene(a)hotmail.com if you want to help us "take out the trash".

Dutch museum needs Kennedy 9300 docs.

by museum＠techniche.com

I've got the service manual that I used to use when I supported them. I still have a couple of drives though so I don't want to lose it. I could make a copy given enough time (it must be ~200 pages). I was planning to do that at some point since there's someone else on the list that I promised a copy to (I'll have to dig up that message to find out who). Do they have an urgent need or are they just trying to prepare for when they need it? Jon > >A computer museum in The Netherlands is looking for the documentation for >a Kennedy 9300 tape drive.

WANG

by franke＠sbs.de

Now a question for the real wiered stuff: Does anybody know a Wang-71 ? I just know the name - I'm right now on a trace of a specific Russian computer, and they told me that this machine is a Wang-71 clone, but I can't find any information about this machine. No, I have no pictures of the Russian machine and no further data. The clone is build 1975, so the original design might me a bit earlyer. Gruss H. P.S.: has anyone a list of PDP-clones ?

Franklin Ace 2100

by fauradon＠pclink.com

I am not familiar enough with both machines to make a judjement on which one is better but the franklin display some features that seem interesting: apple dos 3.3 compatibility, floating point basic, apparently could run CP/M or Pascal (OS?)(not much info on that), programmable function keysimpressive display capabilities (16 colors at 560 x 192), built in parallel and serial interfaces and memory expandable up to 576K. Compare that to the Apple IIe or IIc. The memory extension and RGB interface cards are optional (128K and 80 column color?) It's hard to tell what the exact caracteristics are the users manual keep refering to the technical manual that I don't have.

Partitioning a HD with RT-11 V5.3

My smallest ESDI drive is 150Mb. >How do I go about partitioning the drives? Unfortunatly my Doc set is for >V3, so I can't RTFM on this one. Since you've got a WQESD, you've got two choices with respect to partitioning: 1: Hardware partitioning. Partition your 150 Mbyte drive into multiple 65536-blocks drive through the WQESD firmware. You don't need to do a reformat from scratch; just redefine the disk structure and write it to disk. 2: Software partitioning. Partition from RT-11. Assuming your drive is at LUN 0, you already have the default mappings SET DU0:UNIT=0 and SET DU0:PART=0. The "UNIT" refers to the MSCP LUN of the drive, and the PART refers to the software partition number. Map DU1: to be the second logical partition on the first MSCP LUN with SET DU1:UNIT=0 followed by SET DU1:PART=1. Continue on up until you've used up all the disk. Each PART refers to a logical partition on disk, each of which is 65536 blocks long (except for the last one, which is whatever is left over.) Of course, only the first 65535 blocks of each partition are directly usable, given RT-11's block numbering scheme. SHOW DEV:DU will show you the current partitioning. Keep in mind that if DU is your system disk, you'll have to do a reboot to reload the driver with the "new" partition settings before they'll go into effect. (You wouldn't believe the number of RT-11 5.7 field test sites who complained "partitioning doesn't work" when they simply failed to reboot after the SET DU's! This has been in the manuals for over a decade!) After rebooting, INIT DU1:, etc., and away you go! Since you *do* have the WQESD, I heavily recommend that you do your partitioning at the WQESD level and not at the RT-11 level. This way all your partitions will be hardware bootable. If you do the partitioning through RT-11, the resulting logical partitions won't be hardware bootable. A neat tool (hey, I wrote it, I think it's neat) for looking at MSCP- level stuff under RT-11 is the DUSTAT program, available from ftp://sunsite.unc.edu/pub/academic/computer-science/history/pdp-11/rt/dusta… Tim Shoppa Email: shoppa(a)trailing-edge.com Trailing Edge Technology Voice: 301-767-5917 7328 Bradley Blvd Fax: 301-767-5927 Bethesda, MD, USA 20817

Partitioning a HD with RT-11 V5.3

>I realized something, even if I do get this working, I'm going to need to >partition one of the ESDI hard drives since they are to big for RT-11, >according to the WQESD controllers documentation the partitions need to >be 30Mb or smaller. My smallest ESDI drive is 150Mb. By default, if your disk is larger than 65535 blocks, the physical unit numbers for the DU device map to partition zero (0-65534) of the selected physical unit. If you want to map another unit of the DU handler to another partition, you issue the command: SET DUn UNIT=m part=p where 'n' is the RT-11 unit number, 'm' is the physical unit number in your MSCP configuration, and 'p' is the partition number (starting at zero). For example, say I have an RQDX3 with an RD54 (169mb) and an RX50 (dual drive): DU0 = Partition zero (0-65534) on phys unit 0 (rd54) DU1 = First of the RX50 drives DU2 = Second of the RX50 drives If I want address more of the RD54, I can do the following: DU0 = Partition zero (0-65534) on phys unit 0 (rd54) DU1 = First of the RX50 drives DU2 = Second of the RX50 drives DU3 = unassigned DU4 = Partition one on phys unit 0 (set du4 unit=0 part=1) DU5 = Partition two on phys unit 0 (set du5 unit=0 part=2) DU6 = Partition three on phys unit 0 (set du6 unit=0 part=3) DU7 = Partition four on phys unit 0 (set du7 unit=0 part=4) This is, in fact, how many partitions you would get on an RD54. All of the partitions except the last one will be full 65535 block units. The last one is about 7k blocks. Megan Gentry Former RT-11 Developer p.s.

Tandys gone/Apples anyone?

by backofene＠hotmail.com

I checked the storeroom at school today to discover that all the old Tandy equipment (which had collected dust there for 2 years) has been disposed of. Not even a keyboard left. All I could find is an assortment of Apple II GSes, drives, Imagewriters etc & a few old Mac LCs. Sorry, I remember those old Tandys - 2 labs worth. (used 86-96). They even had an Apple Emulation card (Trackstar) since at that time no one in education could imagine using anything besides an Apple.

mucho Altairs on eBay

by altair8800＠hotmail.com

Looks like the Albuqurque Altairs are coming out of the woodwork. There is now a 680 and a 680b to go with the 8800bt. If anyone was monitoring the auction of the 680 a couple of weeks ago which did not meet the reserve price of $2500 - thought you might be interested to know that it was bought by a buyer in Italy after the auction. The purchaser bought it only to trade for an original 8800 which he has done. It will be interesting to see what happens with these 680's currently up for auction. It appears that the eBay bidders are not very aware of the scarcity of the 680 and are consumed by the hype surrounding the 8800.

The second revision is 23-244E5 and 23-245E5, which I think does support RX33s.

RX50 / RX33 Questions related to PDP-11's

< I am almost sure you need a cable without the PC-twist. Also, you < probably need to set the drive select jumpers properly (Can somebody tel < us what to?). Remember that the PC-twist not only swaps over 2 of the < drive select lines, it also gives separate motor on signals for the 2 dr The "twist" cable only applies to PC or systems using PC patterned interfaces. It DOES NOT APPLY TO RQDX and distribution boards used in Qbus systems. RQDXn uses a single bussed motor on and drive selection by drive select jumper. If you use a RX33 drive try using only one for starters, that will lower the sillyness factor. If you media is RX50... why not use an RX50. If all else fails and your configuring a second system move the controller that works over to the target or move the target controller to the running system as a second drive/unit. Allison

SWTP 6800 on Haggle

by paulk＠microsoft.com

There's a working SWTP 6800 machine on Haggle Online, complete with a doc set. Of course, since it's an Internet auction, he wants $1000 for it, but just in case someone's interested. http://www.haggle.com/cgi/getitem.cgi?id=201793143 Paul Kearns paulk(a)microsoft.com

RX50 / RX33 Questions related to PDP-11's

by CLASSICCMP＠trailing-edge.com

>I am almost sure you need a cable without the PC-twist. Absolutely correct. > Also, you >probably need to set the drive select jumpers properly (Can somebody tell >us what to?). There's absolutely no need to guess on this subject - Terry Kennedy has collected a great amount of wisdom and experience on this subject in THIRD-PARTY-DISKS.TXT, a compendium of DECUServe conferences, available by anonymous ftp from ftp.spc.edu. The answer for the drive select jumpers is easy: first drive at DS0, second at DS1. The jumpers selecting motor speed control are a bit more complicated; Terry's collection of data covers several popular Teac drives, and if the answer isn't there browsing through the Teac jumper setting recommendations will quickly give the answer for any specific drive they've sold. Teac's faxback service is at +1 213 727 7629, and is a valuable source of technical data regarding the various drives and options they've produced (and still produce.) Tim.

Keep in mind that early RQDX3 revisions don't know how to talk to RX33's - they're limited to RX50 floppies. Seeing as how your system is apparently doing bizarre things with the RX33's, this might be the case. What exactly do your "RX33's" do when you try to access them? What firmware revision is your RQDX3? > Can you use RX50 floppies to boot a > system with RX33 drives? Yes. >Will RT-11 boot off of a floppy drive at CSR 17760334? I've tried with >both the Boot disk from my RX50 distribution set, and a RX50 boot disk that >I made using PUTR. I've a sinking feeling that having two disk controllers >is confusing RT-11. To get RT-11 to deal with two DU controllers, you can either: 1. Do a SYSGEN to create a DU handler that can handle more than one DU controller. With recent enough RT-11's, the same handler copes very nicely with multi-port booting. 2. COPY DU[X].SYS to another name (say, DG[X].SYS), and then SET DG:CSR=nnnnnn and SET DG:VECTOR=nnn, where nnnnnn is the CSR and nnn is an unused vector in your system. When you create a bootable floppy which you want to be bootable on your second controller, you must lay down the DG bootstrap instead of DU, since the DU device points to the wrong controller. The tradeoffs between the above two methods are documented in the RT-11 _System Generation Guide_ and the RT-11 _Device Handlers Manual_. Method #2 above is easily the quickest, and will probably do just fine for your purposes. (Though a RT-11 system with extended-unit multiport DU handler is a beautiful sight!) >Is it possible to create a Bootable TK50 with RT-11 that can be used to do >the install? Look for the file MUB.COM on your distribution: ! COPYRIGHT 1989, 1990 BY DIGITAL EQUIPMENT CORPORATION ! ALL RIGHTS RESERVED ! !

I had to trade back some RQDX2s for RQDX1s on some PDP-11/73s I delivered to the gummint because RT-11 didn't support them. I don't recall which version we were using; it would have been at least 5.0. I remember grumbling about how fancy (read "bloated") RT-11 was getting, but I don't recall doing _that_ until 5.2; I thought it happened during the 11/73 incident, though. I also don't remember why I thought 5.2 was bloated (it may have been the UCL/UCF stuff, which I thought was unnecessary), but I did stash away a 5.0 distribution kit as a hedge against bloatation.

An even better hedge against bloatation is to get RT-11 5.6 or later and learn how to use SET RUN VBGEXE. No matter how big the monitors and drivers grow, by appropriately setting a .SAV image's VBGEXE bits you can give it access to "all" 56kbytes of virtual memory space.

old CDS modem

by lfb107＠psu.edu

Found an old modem that I forgot I owned and was just wondering a few things. First, it's a Concord Data Systems 224 ARQ/Autodial that I now remember was in tow by a 3B2 I picked up a while ago. Anyway, it's rather heavy (humongous hat sink on back) so i opened it up and began to think that the innards seemed a bit complicated for a 'modem.' OK, I'll admit it, I was 11 years old when these things would have been in use, but I have other modems from the peiod ('85-'86) that aren't nearly as complex. It's about the size of a large book and has three levels of circuit boards with a Z80 CPU, an SIO chip, and memory chips (one says "zeropower (tm) ram" on it and "DO NOT DISPOSE OF IN FIRE!!!!") on one level, Intel 8031 series chips on another and who knows what on the bottom (haven't taken it all apart yet). Not to mention the 32 dip switches (all off) and the 23 led's on the front. To make a long story short, what did/does this thing do that a regular modem of the time didn't do? Thanks, les

A Commodore 'pre-computer'

by jimw＠agora.rdrop.com

Ok, so it may not fit the 'computer' part of the charter, but it sure fits the 'more than 10 years old' part... (and its borderline cute) Just picked up a Commodore desk adding machine. Its clean, fully functional (all 3 functions... ummm... 3? maybe 2.5 since 'multiply' is manually assisted), brightly colored Commodore tag and icon on the front. I'll be adding a picture on my web pages of it along with my next set of updates, and (hopefully) my pictures from VCF II.

Tandy Keyboard

by roblwill＠usaor.net

Yep. They're PC/XT clones. The Tandy 1000TL's had the microphone port. They had a built-in "Tandy Sound Chip". It put out better sound (in Tandy 1000-supported games) that the standard PC-speaker setting. Haven't gotten the mic to work yet, though. I wish I could find a driver that would run the chip through Windows... I have seen the type that looks like a C64 (can't remember if it was a 1000 or not. They did make the CoCo series, but they didn't have the disk drives. If anyone has one of the 1000's (?) with the built-in drive (and keyboard), and you want to sell it, send me an email, because I'm probably interested. -- -Jason (roblwill(a)usaor.net) ICQ#-1730318 ---------- > From: Max Eskin <maxeskin(a)hotmail.com> > To: Discussion re-collecting of classic computers <classiccmp(a)u.washington.edu> > Subject: Re: Tandy Keyboard > Date: Wednesday, October 14, 1998 9:49 PM > > Are these PC clones?

>When I try using a pair of Teac floppies I've converted to RX33's using >information I found on Sunsite I'm not really sure it tries to access >them. How do you cable RX33's?

Can you use RX50 floppies to >boot a system with RX33 drives? Yes. In fact, the RT-11 distribution on 5.25" floppies is RX50 compatible, which also works on RX33. If the disk is formatted by an RX33, then it will only work on an RX33, though (at least when using the RT-11 FORMAT command). >Will RT-11 boot off of a floppy drive at CSR 17760334? I've tried with >both the Boot disk from my RX50 distribution set, and a RX50 boot disk >that I made using PUTR. I've a sinking feeling that having two disk >controllers is confusing RT-11. Since you're using the distribution kit, the answer is no. The address which the distribution handler (a single-port handler) expects is the primary address, 17772150. Even if you were able to get the boot code to read the boot block into memory, the first time the driver gets control, it will try the default primary address and fail. >Is it possible to create a Bootable TK50 with RT-11 that can be used to >do the install? Even when I worked in the RT development group, I avoided the attempt at making bootable magtapes... But the answer is, yes... you could make a bootable magtape (TK50). But you need to boot an RT system to do so, so we're back to a chicken and egg problem...

The problem with this technique is that the handler name is built into the driver, which is used by XM to locate the extended memory region used to store data (and other code), and the two handlers would still have the same name. You would need to SIPP the new handler and search for all references to the name 'DU' (search for ;rDU) to 'DG' (;rDG).

RX50 / RX33 Questions related to PDP-11's

by healyzh＠ix.netcom.com

OK, I've got some more questions. It seems I've finally got the PDP-11/73 I'm working on to talk to the floppy drives. BUT, it won't boot my RT-11 RX-50 floppies. I'm using the RQDX3 controller as the floppy controller and the WQESD (ESDI) controller as the boot device. When I tell the system to boot from DUB0 or DUB1 which is the terminalogy that the WQESD controller expects (figuring that out, i.e. reading the manual took longer than I want to admit) with a RX50 attached, it will access the floppy drives, this is best evidenced by my using a cleaning floppy in the drive (made it easy to hear the drive being accessed). When I try using a pair of Teac floppies I've converted to RX33's using information I found on Sunsite I'm not really sure it tries to access them. How do you cable RX33's? I set them to Drive 0 and 1, as the docs said, and then used a Y-splitter for the power with a standard PC floppy cable (do I need one without the twist?). Can you use RX50 floppies to boot a system with RX33 drives? Will RT-11 boot off of a floppy drive at CSR 17760334? I've tried with both the Boot disk from my RX50 distribution set, and a RX50 boot disk that I made using PUTR. I've a sinking feeling that having two disk controllers is confusing RT-11. Is it possible to create a Bootable TK50 with RT-11 that can be used to do the install? Zane | Zane H.

The diskettes drives are 40 track and 35 track compatible The ACE 2000 has no disk drive, the 2100 has one and the 2200 has two (my 2100 has two, must be an upgrade) I think my 2100 also has the etended memory card that brings it up to 384K.

RX50 / RX33 Questions related to PDP-11's

(The reason for this is because back when the driver was developed, someone decided that since the vector was programmable, and the default was at 154, and nothing was at 150, that subsequent vectors would decrease by 4. This was then extended to the CSR... It wasn't until later that we found that the default secondary CSR was to be at 17760334. It never got changed.

Wyse PCs (was Re: auction grabs)

In a message dated 98-10-13 20:40:07 EDT, you write: << he few ISA cards was a 16-bit double card with a 9 pin external plug labelled Wyse monitor. There's 2 badly mounted Wyse E-Proms. Printed on the bottom of the top board was WY-700 Controller Daughterboard. Wyse Technology (c) 1986. The bottom one has WY-700 PC HI RES MOTHER BOARD. Sounds like your beast. If I should find one of these monitors would it work on a clone with just this card ? T >> Yes if you plug the card in and plug the matching 700 monitor in it will come up. The card emulates EGA & CGA. In its high res mode it is a nice sharp 1200X800 (approx.) monitor. It was supported by many early desktop publishing software packages in it's high res mode. The original card & monitor set predated VGA and was an 8 bit double card. I used one on an XT for several years. SVGA finally killed them off. I think I still have that XT. I know I have two of the monitors in my whse, If I don't sell them beforehand they will be in my Auction in early November. I am retireing from supporting a warehouse so most everthing is selling. This will include lots of older computers, parts, terminals, printers and lots of collectable stuff. Paxton

RX50 / RX33 Questions related to PDP-11's

by CLASSICCMP＠trailing-edge.com

> At this point, if you don't have >a floppy in the RX50, the DEC BOOT ROMS will hard boot >an alternate CSR for UNIT 0, PARTITION 0. The situation depends greatly on *which* version of the DEC boot ROM's are in use. Some automatically search for an alternate CSR, some allow you to specify it explicitly. The situation is complicated by the fact that for most DEC OS's, the alternate DU CSR is 160334, while for RT-11, SYSGEN will certainly suggest something very different for the default: > 230. What is the CSR (register) address for the second port (172144)? While most DEC DU bootstraps "sniff" through 172144, not all do. Luckily, we don't have to argue about the situation, as Zane told us which bootstrap he is using: >When I tell the system to boot from >DUB0 or DUB1 which is the terminalogy that the WQESD controller expects So any discussion of DEC bootstrap revisions seems to be quite irrelevant :-) For many purposes, I much prefer the WQESD boot scheme. It avoids all the confusion caused by the many, many different DEC DU bootstraps! -- Tim Shoppa Email: shoppa(a)trailing-edge.com Trailing Edge Technology Voice: 301-767-5917 7328 Bradley Blvd Fax: 301-767-5927 Bethesda, MD, USA 20817

IF the drive speed select and density select jumpers are set right it (using RQDX3) will sense what the media is and operate correctly using the DU boot. None or all of this will be true for the WQESD controller, I don't know it. < Will RT-11 boot off of a floppy drive at CSR 17760334?

For RQDXs the LUN jumper must corospond to how many units. I believe PDP-11 ROM BOOT expects to boot from the default first (*2150) unless the DU.sys driver has been changed for the second address. RT-11 itself will boot/run on anything you have a driver for. Megan would know for sure. I've never found it necessary to have two MSCP disk controllers in a PDP-11 (I was using them in the vax instead!). < Is it possible to create a Bootable TK50 with RT-11 that can be used to < the install? That's oblique. It's possible to make a bootable RX50(or RX33) that is complete enough to be a system! To install from that is trivial as it's really INITing the target drive (assuming its LL formated) and copying everything to it then doing a copy/boot operation. Not much majik unless the version of RT has been really tweeked. Allison

There is a 3 part series about the first MMD in the May, June, July 1976 Radio Electronics. It is an 8080 based system with 24 output bits and LED's, keypad, a solderless breadboard, 256 bytes ram (2x 2111), and 256 bytes rom (1702A). The article has the schematic and "monitor" listing and sample programs. I almost bought one a few years ago, but the price was too much, USD $150. By the way, the kit price back in 1976 was $350, assembled $500. -Dave

Picture up (RE: Microsci HAVAC)

by roblwill＠usaor.net

I noticed that ( I looked a 3 Disk II's that my school had, and they all had the grooved disc). I don't have the drive anymore (never was able to get it to work), but All I really remember is the round cable, the red apple (it was unusual), and the Disk II-type black front. If I remember correctly, the case was black, too. I don't remember a data cable (at least built on to it, like the Disk II) though. I can't remember if the round cable was for power, and there was a plug for data, or if the round cable was for power/data. I do remember that the plug was cut off the round cable, though. It was about as round as a AAA battery. I think it had five conductors. -- -Jason (roblwill(a)usaor.net) ICQ#-1730318 ---------- > From: Sam Ismail <dastar(a)ncal.verio.com> > To: Discussion re-collecting of classic computers <classiccmp(a)u.washington.edu> > Subject: Re: Picture up (RE: Microsci HAVAC) > Date: Monday, October 12, 1998 11:00 PM > > A round cord?
