Hello; I have here my first Sinclair ZX81 Computer with 16K Ram extension. To check if the Ram extension works properly i want to write an small Basic program to check each byte. The first thing i struggle on is that 1 could not type in a for next statement. 10 FOR I = 17000 TO 32768 if I type in this line, the ZX81 mark an inverted "S" just before "TO". 10 FOR I = 17000 "S"TO 32768 I found out that the ZX81 "think" that there is an Sytax Error with the TO. So i tryed all combinations with and without spaces in that basic line.... Nothing matters. Is there someone who knows about that behaviour?

Available: HP3000 serie 52 parts

by anders＠abc80.net

Hi, I have a bunch of PCB's from a HP3000 series 52 computer. Is some one interested in those? The machine itself was still working when it was taken out of service in the late 1990's. No guaranties are given though. The location is in south of Sweden, but I'll guess I can pack them and send them elsewhere. There is also a power supply available. A disk station and some kind of a tape drive, each sitting in a cabinet of their own. Free for pickup. Don't know more than this, but I can find out more details if anyone is interested. /Anders

Fwd: How to disassemble the DEC PC05 puncher unit?

by j_hoppe＠t-online.de

Hi, I have an broken DEC PC05 puncher unit here. It seems the shaft which transfers motor power to the excenter mechanism is broken in the inside. So i need to dissassemble the whole unit, but have no idea where to start. I've read somewhere the mechanical puncher unit is not made by DEC but by some other company. Is there any known documentation about the DEC PC05 puncher ? Thanks, J?rg

I must admit that I used to scorn those durned kids using Arduinos to do the job of a 555. But then I pulled my head out of my ass and realized that times change, nowadays a microcontroller is as cheap and common component as a 555 was[..] I think I'm reasonably well into the pragmatic camp (ref. Chuck G.'s post). But one point about 555s and Arduinos is that I couldn't build a 555 more easily than I could build the MCU on an Arduino board (a more relevant comparision might be a 555 vs a Propeller chip) - they're all black boxes to me. Even a transistor, to some extent - I know exactly how it works, well, as much as any other EE anyway, but I couldn't build one. Or a vacuum tube..

IBM 5120

by ggs＠shiresoft.com

I had acquired an IBM 5120 a few months ago but I didn?t have time to really check it out. It?s a fairly pristine example (32KB) with dual 8? floppies. It also came with a few manuals including the Maintenance Information Manual as well as the Computing System Logic Manual (still shrink wrapped). It also has a serial I/O diskette and a diagnostic diskette. It also came with a printer but I have not yet unboxed that yet. When I originally unboxed the 5120 I was a bit disappointed in that the shipper didn?t pack it as well as I would have liked (styrofoam peanuts) but there was other packing material so it wasn?t a complete disaster. Since it was a working unit prior to shipment, after an initial inspection, I powered it up only to have nothing happen. :-( I proceeded to take the covers off and noticed that the fuse for the display had blown. It was likely vibration related since I didn?t see nor smell any burnt components. Replacing the fuse, I saw that the cathode filament was lit but still nothing on the display. :-( After removing the logic chassis and removing all of the foam ?gunk?, I noticed that a couple of the boards as well as the connectors for two of the boards were loose. After reseating everything, success! I haven?t yet done a complete checkout yet, but I did enter a small BASIC program and it ran successfully. Now I have to find some IBM formatted 2D diskettes for this so that I can save what ever programs I enter. ;-) TTFN - Guy

Altos ACS 8000-15A

by fozztexx＠fozztexx.com

Last week while bored and browsing eBay looking at things that are ending soon something I had never heard of caught my eye: an Altos ACS 8000-15A. I looked at the pictures and googled the brand and model and it didn?t seem to be a very common computer and there were no bids on the item so I put in a fairly low bid. I ended up winning! :-) The seller asked if it would be ok to bring the item to me the next time he was in my area. I figured that was fine since I was concerned that since it has a large 8? hard drive in it that it would be more likely to be damaged in shipping. I actually didn?t even need to wait very long! Friday he set out to drive across 2 states and dropped off the computer at my front door on Saturday morning. Talk about excellent service! I buy lots of untested items on eBay and usually they work just fine. But luck hasn?t held for me this time and so far the Altos doesn?t work. I can hear the drives spin up and all the voltages from the DC power supply are perfect. But nothing spits out on the Console 1 RS232 port. From what I understand the serial ports are wired DTE (which seems odd since you use it with terminals) and so I?m using a null modem adapter. Although with the null modem or without I get nothing. Anyways, I posted an album with lots of pictures here: http://imgur.com/a/9X8Gh Yay another project for me to fix! :-) -- Follow me on twitter: @FozzTexx Check out my blog: http://insentricity.com

PDP-12 at the RICM

by michael.99.thompson＠gmail.com

J. Victor Nahigian donated some M221 and M222 boards for the processor and TC12 LINCtape controller. They are in pretty bad condition, but are repairable. Warren wrote a test program for the M222 boards, and some of the just donated boards actually work OK. It will be nice to have some spares. Dan (the donor) brought over the now lubricated top of cabinet fan. He had to make some special tools to disassembled it but was able to lubricate the dry bearings. We will reinstall it next week. He also dropped off the system logbook and more diagnostic manuals. More scanning for Bitsavers! It is really interesting to see the service history of this system since it was new. The LICM scanned some of the missing MAINDEC documentation so we were able to run: MAINDEC-12-D1AC-D Extended Memory Control (EXTMC12) MAINDEC-12-D8CC-D_KW12A_Clock_Test Fails test #11 where the AC should be 0000 and is 7777 on the CLRB instruction. MAINDEC-12-D8CA-D-(D) KW12 Real Time Clock Diagnostic (KW12TST) shows the same failure mode as D8CC. MAINDEC-12-D6BA VR12 Display Test Runs, but we have no display connected. We connected the 'scope to the outputs of the VC12 display controller when MAINDEC-12-D6BA was running. Without a way to interpret the intensify signal, and no persistence in the phosphor, the resulting image was not too good. At least we know that the display controller is responding to commands and outputs signals that look reasonable. We reran MAINDEC-12-D3AD-D-D Tape Control Test Part 1 of 2. It still fails at 3400 with the error message "LGP GP=GPC PRESET" printed. We reran MAINDEC-12-D3GA-D-D Tape Control Test part 2 of 2. That runs fine. I bought the matching terminator for my current probe and was able to give it a try today. The normal setting for PDP-12, PDP-8/I, and PDP-8/L core is 320mA. When we debugged the core we set the voltage regulator to the middle of the high and low voltage settings that caused periodic errors. The low going part is the read current and the high going is the rewrite current. The result turned out to be 316mV for the read. Not too bad! -- Michael Thompson

A 'good-enough' H960 |d|i|g|i|t|a|l| PDP11 masthead replica

by steven＠malikoff.com

Following the recent discussion here on the 'DEC logo' topic, I've been mucking about with my own efforts to produce a replica PDP11 masthead panel for the DEC H960 rack. The idea is basically to make an SVG for a vinyl stencil which looks 'good enough' until I can find an orignal one. I've drawn CAD (vectors and arcs only - no splines) over images I've found on the web, from scratch, without relying on the Batchelder examples. So far the output is virtually complete but I need some help from the list, if possible - I would like the dimensions of the width and height. I know it's larger than a DEC filler panel. With thise I can adjust the drawing to the final size and continue on the project. As I need to mix a blurb with example images I've placed it under a blog entry on the VCF board at http://www.vintage-computer.com/vcforum/entry.php?544-A-good-enough-replica… Please take a look, and thanks for any help or comments, Steve.

A 'good-enough' H960 |d|i|g|i|t|a|l| PDP11 masthead replica

by jnc＠mercury.lcs.mit.edu

> From: Pete Turnbull > z = about 0.5mm - you're trying to measure the taper on the edge of > the flange? Not easy to be accurate. Ah, I've just realized I made a mistake in a previous message. I thought 'z' was calling for the distance between the inner edge of what I'm calling 'the flange' (i.e. the edge the left-hand arrow of 'x' is pointing to), and the upright at the right end of what I'll call the 'bottom plate' (when the piece is mounted on the H960, the bottom plate is in a plane parallel to the ground - i.e. it's in a plane perpendicular to what I'm calling 'the flange'). That upright is the vertical (in this picture) axis at one end of 'z'. Having called up a flat plate, and a square, to help measure accurately, the width of the flange ('x') is 1.26 cm, and the distance from the outer edge of the flange to the vertical at one end of 'z' (i.e. the end of the 'bottom plate') is 1.57 cm at the 'bottom' of the plate (i.e. in this image), making the distance from the inner edge of the flange to the vertical edge of the bottom plate 3.1 mm - at the 'bottom' of the bottom plate. At the _top_ of the bottom plate (i.e. the inner edge, when the unit is mounted on an H960), the distance to the outer edge of the flange is 1.62cm, making the 'flange inner edge' to 'bottom plate side' distance 3.6 mm, at the 'top' of the bottom plate. So 'z', the variance between the two, is indeed 0.5 mm. Pete's spot on! Noel

PS: To clarify (if needed) what I mean by 'the flange': orient the piece as it would be if it were on the H960 (i.e. with the little interior tabs at the top, and the coloured panel on the front); the 'flange' runs down one side, along the bottom, and up the other side: it's a continuous piece, towards the back of the unit, in a plane parallel to the plane of the coloured front panel.

A 'good-enough' H960 |d|i|g|i|t|a|l| PDP11 masthead replica

by jnc＠mercury.lcs.mit.edu

> From: Steven Malikoff > I'm not sure I interpret Pete's measurement of 33.1mm from the back of > the flange to the front of the box, correctly. Noel also says the same > 'from the back of the flange' so I must be missing something here. Hmm. I thought for a moment I'd misread my calipers, but I checked again, and 3.80 is correct for the thing I measured, which is (on your IMG_3161) from the lower end of i/j to the upper edge of d/g. So clearly we must be using different definitions of 'flange', or something - or maybe his unit is somewhat different from mine? Here are the rest of the measurements from that image: 'k' = 'm' on mine, at 1.15 cm. That downward projecting flat (at one end of 'l' and 'm', which is at 90 degrees to the thing I'm calling the 'flange', the thing with thickness 'i', which is completely horizontal - along two axes - in that image) is cut back a bit, in the direction normal to the screen, from the end of the upper part (at the left edge of 'k'), which is why they look, from the slight angle in that image, like they aren't in a common vertical plane (normal to the screen) - but they are. 'l' = 2.6mm; 'h' is 10.64 cm; 'd' is 5.73 cm; 'i' is 2.70 mm. 'g' looks to be about 4.6 mm; I should mention that the corner below it (at the upper end of 'i') is not a right-angle, but a rounded thing with a fairly considerable radius - something on the order of 3.5 mm. 'j' is 3.35 cm. The edge labelled 'flush with bottom edge' is indeed flush with the left-hand end of the horizontal flange. On IMG_3162, 'q' is 1.16 cm; note that the left edge of 'q' is almost, but not quite, in a plane with the right hand edge of 's'. The left edge of 'q' is about 3.4 mm to the left of the right edge of 's'. 'u' is 1.13 cm. (This turns out to be 'z' in the third image.) Note that the little tab (the thing you're measuring 's' on) projects up under the 'plate' which you're measuring 'u' on; i.e. the maximum width of that tab, 't', is up underneath that plate. I can't measure it because it's not a sharp angle where it meets the vertical surface (i.e. in the plane normal to the screen) up under there; rather, it's a radiused corner (which you can see in the next picture). On IMG_3144, 'y' is about 1.56 cm (bit hard to measure that one; I should have used a flat to give me good end point at the RHS to measure to); 'x' is 1.25 cm; 'v' is 9.1 mm (ditto); 'w' is 2.85 mm. 'a' I can't really give you directly, but I can give you the distance from the upper end of a, to the upper end of 'w', which is 7.96 cm; add that to 'w' and 'v' and that will give you 'a'. Noel

Schematics/Service Manual for Yamaha C1

by ethan＠757.org

I'm just going to toss a feeler out there. One of my more recent most sought after machines was the Yamaha C1, a 286-12mhz MS-DOS "laptop" with 11 midi ports. I picked one up off of ebay, not cheap in it's non-working condition. I'm now working on getting it running. I'm looking for schematics or service manual. It's a long shot :-) I contacted Yamaha of USA already and they said they don't have documentation going back that far. Both paper or digital. My unit when powered on never seems to do a floppy seek, or boot. Caps lock and num lock don't trigger the LEDs. And it has an internal or external display dip switch. The unit always comes up set for external display, even though dip switch is set internal. I hunted inside and found 9 electrolytic caps were leaking. I cleaned up the mess and replaced them, but still no go. The traces I can see that look on the fence all continuity test okay. I have more caps on the way to replace all of the capacitors, and next step will be to look at the power supply output on an oscope to see how good or bad it looks. I have already archived the eprom data, and will be scanning all the documentation and archiving the floppies. I will make it all available online. I have some of the programming docs, some dip switch info, pinouts for the expansion connector (but unfortunatly no hard drive controller connector afaik) and more. Schematics would be good to go with that, as the mainboard has more than 2 layers. -- Ethan O'Toole

PDP 11 - how to lock heads in a rx01 and rx02 - seeking advice

by lyokoboy0＠gmail.com

I asked for advice a while back on what to expect with moving a pdp 11, I was told to lock the heads in the rx01 and rx02 drives. I'M getting pretty lost in all the information about the drives, are there any good guides or sites with lots of pictures of the drives taken from different angles apart so i can get a better idea of what im going to be working with? Also, people tell me getting the drives off the rails and out of the rack is a pain, where would i find the appropriate information on how to do that? I really don't want to take the drives out of the rack, but if it comes to it, i would like to know how. I am scheduled to pick this stuff up in 5 days. --Devin

PDP 11 - how to lock heads in a rx01 and rx02 - seeking advice

by jnc＠mercury.lcs.mit.edu

> From: devin davison > I was told to lock the heads in the rx01 and rx02 drives. Err, I think we told you to lock the heads the RL0x's, not RX0x's; the former use large rigid packs, the latter are 8" floppy drives. AFAIK, there is no need to lock RX heads when moving them - there is nothing in the manual about RX drives being shipped from DEC with the heads locks. > are there any good guides or sites with lots of pictures of the drives > taken from different angles apart so i can get a better idea of what im > going to be working with? Not that I know of, but the DEC manuals (mostly available online) are adequate. > Also, people tell me getting the drives off the rails and out of the > rack is a pain, where would i find the appropriate information on how > to do that? See above. > I really don't want to take the drives out of the rack, but if it comes > to it, i would like to know how. That's very wise - my last removal, it _really_ helped that I had read the DEC manuals before-hand, as I wound up performing a removal I hadn't planned on, and that had a tricky step I probably never would have found on my own, but which I had luckily read about in the manuals. Good luck on the move! Noel

via The Rescue List ---------- Forwarded message ---------- From: Aaron Browne <gopodge at gmail.com> Date: Wed, Jul 1, 2015 at 7:43 PM Subject: [SunRay-Users] Surplus SunRay 2 and SunRay 3 Units - Victoria/Australia To: SunRay-Users mailing list <sunray-users at filibeto.org> The company I work for is about to undertake a total endpoint replacement. We are replacing all of our SunRay 2 and SunRay 3 devices - hundreds of units of both types. All units are in working order. Is anyone interested in providing a new home for any of these devices? Otherwise, they are going to be recycled. Victoria/Australia is preferred destination but we can talk other parts of Australia if required.

A 'good-enough' H960 |d|i|g|i|t|a|l| PDP11 masthead replica

by jnc＠mercury.lcs.mit.edu

> From: Steven Malikoff > It appears the top edge projects further than the bottom by a tiny bit > leading to a tapered appearance, but I assume the plane of the printed > inset panel is parallel to the exterior mounting surfaces. By top edge I assume you mean the top edge of the unit (we need a common term for the entire injection-molded plastic thingy), as it would be when mounted on the rack? And the distance you're talking about is the distance from the very front of the unit to the flange that projects out around the unit on three sides (sides and bottom), right? OK, I'm measuring mine (with calipers :-), and from the back of the flange to the front of the rim around the coloured insert, it is 3.80 cm at the top, and... 3.80 cm at the bottom. So no tapering. (And it's the same on both sides.) > A common method of determining radii is to use an engineers radius > guage. Which I don't happen to have... something to add to my tool wish-list! :-) > Failing that, try fitting a series of circular objects (coins etc.) > which can then be measured with calipers or micrometer. I did try with the butt ends of a number of large drill bits, but I didn't get really good results. I mean, you can tell when it's way off (too small, and the object 'lifts' off the surface at the outer edges of the object, too large, and you get a gap in the middle), but there's a range in the middle where it's hard to tell - it all depends on where you decide the ends of the curved part are. Oh, one note: when I gave the gap between the coloured insert, and the sides of depression it sits in ("it's slightly smaller than the inset in the plastic housing, by about .5 mm"), that .5 mm is on each side, not total.

I have requests from several list members to stop b y and do some shopping/ trading. I'm still on the mend from my latest replacement shoulder and will be out of commission for quite a while yet. While not quite up to the show, I have no problem with members stopping by. But I still have doctors appointments, PT, etc. I can see I-74 from my house and am about 10 miles west of I-57 by Champaign, IL. There are several good routes to Chicago from here, which is about a 3 hour drive. If anyone wants to stop by I only ask that you make a ball park appointment that will not interfere with my medical appointments. If I have an idea of what you want (LA120s, monitors, other large things) I can have it out and ready. I should be able to have some of my high school helpers to help pack and load. I'm not a morning person, but can make it work. Nighttime doesn't bother me at all. If I missed anything or have general comments, please reply. If you want to set up a time or have specific questions, please contact me off list. Many Thanks, Paul

A 'good-enough' H960 |d|i|g|i|t|a|l| PDP11 masthead replica

by jnc＠mercury.lcs.mit.edu

> From: Steven Malikoff > a replica PDP11 masthead panel for the DEC H960 rack. That would be great! (I'd buy one! Or more!) But how are you going to produce the plastic housing? I suspect that's going to be harder than the inset coloured panel. > I need some help from the list, if possible - I would like the > dimensions of the width and height. The inset (the coloured part) is 8.45 cm high (it's slightly smaller than the inset in the plastic housing, by about .5 mm); alas, I don't have a metric ruler long enough to measure the width directly, but in Imperial it's 3-21/64" by 18-9/16". I don't have a good way to accurately measure the radius in the corners, but it seems to be about 8.5 to 9.5 mm. > I also would like to know of the outer edge of the masthead is a beige > colour, or even silver. The raised edge around the inset panel is painted a dull silver - like the old silver paint, but with a touch of grey in it. The edge itself is 4.1mm wide, according to my calipers. > The panel would be the inner bit with the radiused corners, the edges > being a seperately cut panel which is in front of the the detailed one. Not sure I follow this? The entire top unit, including the raised edge around the coloured inset, is a moderately complex injection moulded plastic piece; behind the front, it's kind of like a box that's open at the back, and there's a ridge around the back edge on three sides; the bottom edge is shorter, and the top edge is extended further back. Finally, there are a couple of internal tabs where it actually connects to the H960. If you want an original to copy, TopLine has one for sale on eBay (ignore the ridiculous price they've got on it, they are very reasonable). > I would also like to know how deep the recess is for the front. I > suspect the same as the filler panel bezel edge, about 3mm. 4.0 mm by my 0.5 mm ruler. > And also the depth of the plastic backing. You mean, how thick is the plastic in the housing? 2.7 mm in one place, 2.8 mm in another, 2.3 mm in a third? Interestingly, IYWR, in previous thread we'd mentioned how other people produced their own insets; one for a terminal server, and one for the LISP Machine. I looked at my LISP Machine one, which I had assumed was in a similar housing, but it's not! It does indeed fit on an H960 (the early LISP Machines were built in H960's), but it's quite different. It's in an extruded aluminium unit (of constant cross-section), with no end pieces (although the bottom plate has small squared cut out of the corners); the extrusion's cross-section is exact a capital 'F', but upside down. There are little square 'serifs' on the 'back' of the 'F' (the front side, when installed), and the printed panel fits in between them. Now that I look at it, it looks very similar to me to some things I seem to vaguely recall being used on earlier DEC machines (either a PDP-6, or a KA-10, I don't recall where it looks familar from). It being a more-expensive aluminium extrusion makes sense; that was back when that sort of thing (along with lots of lights! :-) was acceptable. Noel

However, under Netscape 7.2, I am able to CLEAN CACHE and that did seem to restore everything back to before I accessed the links. At the very least, all of the files that were placed into the \cache\ sub-driectory were removed and the total number of files and sub-directories reduced to the original value from before the links were accessed. I don't know if making sure that there are no extra files and sub- directories around after I use Netscape 7.2 to download my e-mail, but I use that criteria to determine if anything that should not be present has been added to the C: drive. I realize that pre-existing files could have been corrupted, but I can't monitor everything. Also, after I download the incoming e-mails, I physically disconnect the cable to the router so that any e-mails with links that could be activated to files that might cause a problem can't be completed without the internet being available.

The primary processor is called the "executor" and the second ?is called the "fixer." The fixer is either halted or runs a small loop keeping the translation buffer (TB) full. When the TB logic detects a fault for the executor, it is put in wait state and the fixer is restarted (if ned be) and refills the TB. When it's valid the executor is allowed to come out of wait state (a very slow memory fill). When the 68010 was released we make a small change the CPU board (a couple of PALs) and allowed the executor to actually fault. But the fixer still did the TB fill. But the executor could do a task switch and run some other code, while the fill was taking place. I'm not sure if Apollo updated their original CPU board or just designed a new one with the 68010, I would have to ask some one like Les Crudele to find out for sure. And Sun never did the Forest Baskett dual 68K trick. Sun-1's with 68000 ran a V7 version of swapping Unix (originally from Unisoft) until the 68010 came out when they could support VM on the "SUN-2" and Joy et all moved BSD 4.1 to it. One other note about the MC-500. If was the first commercial Multiprocessor UNIX (predating the 386 bases symmetric boxes but a few years) as well as being the first real time UNIX box. I still have working one in my basement. It has 4 CPU boards in it with a 68010 and 68000 on each, plus a 68000 in the display processor, a number of 29000's in the FP and APP's units, more 29000 logic in the Data Acq Unit, as well as 80186 in the network processor. All in all, a pretty neat federation of processors each doing their thing. Pretty cool for early 1980s' Clem

List Gripes

by chocolatejollis38＠gmail.com

Well, I am once again re-subscribed to this list. Why it or its moderators decide to unceremoniously unsubscribe me every few months without warning is beyond me. Especially annoying when subscription requests always take 2-3 days to process. It would be _really_ nice to do a warning message to people who haven't broken any list rules and haven't asked to be removed before dumping them, especially if this is an automatically-triggered event based on the member's lack of posting activity. Just my two cents.

Search engines index the information from there. Near as I can tell Jay plans on it being online 24/7 and there are no blocks to search engines reading the information and including it in their indexes. Nothing about html format prevents search engines from capturing the information as accurately as text formatting.

And I pointed out that some people had warned that all of our discussions were being included in search engines <Google>, as a possible source of objection. I only included that point because the same people lobbying for text form may also be the ones who may not want list traffic in search engines, and I conceded that is a separate point.

I know there are several people around with the larger VAXes in storage. That's why I asked about the "working condition" - I'm sure the number of big VAXes that could be switched on, say, this afternoon, is quite a bit smaller.

How many use old browsers (e.g. =< Netscape 4 or IE 6) as their ONLY source of web content?

by terry＠webweavers.co.nz

Hi, I'm engaged in a Retrochallenge project where I'm recoding my classic-computers.org.nz site to make it suitable for mobile platforms. I want to modernise the code as well, making it as close to HTML5 standard as I can The RetroChallenge blog site is here. http://www.classic-computers.org.nz/blog/2015-06-29-recoding-classic-comput… . In doing this, I will probably need to say goodbye to old browser compatibility. As in old I mean Netscape 4 or earlier, and other pre-2000 browsers (and possibly IE 6, as it's not very standard). The website does have a few articles and resources of interest to vintage computer hobbyists, which I wouldn't want to make inaccessible. The question is, how many guys like us, those who dabble with old tech, are likely to use ancient browsers as their ONLY source of web content. I suspect not many. Should I worry about it? Any comments welcome. On a related note, I'd be interested if anyone on the list CAN'T read this page properly: http://www.classic-computers.org.nz/blog/temp.html It's a new blog page template I've developed using HTML5 and is mobile friendly. If it doesn't show up properly I'll be interested to know what browser you're using. Please be kind about the HTML5 and CCS code. I don't do this for a job, and it's a big learning curve for me. P.S. Here are some interesting stats. For myself, I've been a Chrome user for a number of years now. http://www.w3schools.com/browsers/browsers_stats.asp Terry (Tez)

OP (about the 68000 box) here ? thanks for all the informative comments! I did spend some time using the 68010-based Apollo workstations, and as I understood it they were equipped with two processors, one shadowing the other, because not enough information was saved to completely restart an instruction ? particularly a block transfer ? if a memory paging operation was required. Apparently the 68020 somehow fixed this problem. (The 68008, BTW, was just a 68000 with limited address space and an 8-bit data bus. It was primarily targeted at deeply embedded systems, not ?general purpose computing? applications.) Thanks for the clarification about V7 Unix not requiring demand paging; this makes complete sense, since it was never mentioned in any of the documentation I read. And yes, it it was Unix V7, not ?System 7? (sorry, it was a while ago...). Thanks for the pointer to the Convergent Technologies boxes. This wasn?t them (the case was different: it was black, and horizontal-profile), but the functionality looks very similar; they could easily have had the same motherboard or other guts. Also, I forgot to mention in my original post that there was a 5-1/4? floppy on this thing, too. ~~ Mark Moulding

In the late 80?s, I bought from a surplus/junk shop a (by then somewhat obsolete) Unix computer, branded UniSys, I think. It had 10 serial ports; one was the primary console, one was intended for a printer, and the other 8 were regular user TTYs. The processor was a 68000 (not 010, 020, or anything else), I don?t remember how much memory, and it had an integral full-height hard drive as well (60 mB, maybe?). When I say Unix, I mean real System-7 Unix ? not Linux or any other *nix. I thought it was really a pretty neat system ? 8 (or 9) users and a printer, just perfect for a small office ? or my apartment at the time, which had a terminal or two in every room. I learned how to program in Unix on that machine, since it matched exactly the System 7 manuals I had. Sadly, time moved on, I got married, and got rid of a bunch of ?useless junk?, like that computer. Recently, I?ve been reminiscing and poking around some on the Web to try to find information about it, but it seems to have vanished completely with nary a ripple. Has anyone else stumbled across this unit, or at least have any knowledge of it? It was a black case, about the size of a standard IBM-PC, with ten serial ports on the back and not much else. I?d sure be interested to know where I might locate data about that unit, or (gasp!) possibly even an existing one... ~~ Mark Moulding
