Hi, work related I'm afraid...... Does anyone have circuit diagrams for Tandem 6530 or TS530 terminals? I have several that I need to repair, as our re-seller will no longer support them. I suspect that the TS530 is a rebadged item from someone else (NCR?), but don't know for sure. Thanks Jim. Please see our website: www.g1jbg.co.uk

Sun drive array

by dgy＠DakotaCom.Net

Hi, I've got one of these (below) drive arrays: http://www.acc.umu.se/images/archive/20020926-RSM2000/DSC02816.t.jpg I.e. *just* the drive assembly. But, from digging around, I *think* it is not just a JBOD (like a D1000) but, rather, requires "something else" in order to make the electrons do their magic dance. Of course, I don't *have* that "something else"! :-( *But*, I would be quite happy using it as *just* a JBOD! My question(s): the box has what appears to be a HD SCSI connector on the back of it -- though it doesn't carry the expected SCSI logo (or any other similar labeling). Is this, in fact, a standard SCSI i/f? Or, is it some bastard interface intended to talk to that "other box" and coincidentally using a SCSI-ish connector? If it is a SCSI i/f, is it HVD, LVD, wide, etc.? (I ask because I have had all sorts of trouble trying to talk to a D1000). Thanks for any pointers! --don

Where have all the Selectrics gone?

by darryld1＠cox.net

I am looking to purchase some type of old printer/computer that will print like an old IBM printer that was used in auto manufacturing plants in the 1960s. The font is much larger than any typewriter I have seen, but even that would serve my purpose if it were available. Can you help me out or steer me in the right direction?

Where have all the Selectrics gone?

by kapteynr＠cboe.com

There was also an article in a hobbyist magazine explaining how to do a homebrew conversion of a Selectric typewriter to make a computer printer. I know, because, as a kid, we were always on the outlook for a junk Selectric that could be salvaged. I doubt that a lot were converted, because Selectric typewriters were always very expensive -- approaching the cost of "cheap" printers. -Rob -----Original Message----- From: cctalk-bounces at classiccmp.org [mailto:cctalk-bounces at classiccmp.org]On Behalf Of Richard Sent: Tuesday, March 21, 2006 1:09 PM To: General Discussion: On-Topic and Off-Topic Posts Subject: Re: Where have all the Selectrics gone?

I seem to be accumulating some VLB stuff, would anybody here find it useful? It's mostly I/O cards (many including floppy and IDE interfaces and the other more usual stuff) and some video cards.

ImageDisk / PC FDCs & single-density

by dave06a＠dunfield.com

Hi Guys, I've found about 6-7 systems around here that work fine with ImageDisk and single-density. I've also tested all of my systems using Chucks handly little TESTSD utility ** and I get an exact match - the systems that work with IMD and single-density are reported OK by TESTSD and those that don't work with IMD and single-density are reported as "failed" by TESTED. ** for those who are unfamilier with it, TESTSD formats the top 5 tracks of drive A as single-density and verifies that it can read/write it. You can easily make up a floppy that you can boot and use to test for single-density (thanks Chuck). I also have corresponded with quite a number of people who have gotten IMD and single-density to work on other systems, so I know that it is basically functioning correctly. I've been corresponding with a chap who has been trying to get IMD to work at single-density without success. I gave him the TESTSD utility to check out his systems, and also mentioned that I have heard "good things" about Adaptec controllers. This is his response: ----------------------------------------------------------------------------------------------- I tried two adaptec controllers I had here. The first - an Adaptec 1542CF wasn't reported as compatible by the TESTSD program, and doesn't work. The second, a simpler Adaptec 1522A is reported as compatible, but doesn't write the Osborne SD 5.25" format using IMD. Interestingly however it will write it using Teledisk. It also will read correctly with Teledisk, but not with IMD. Strange stuff! It uses a DP8473AV as the floppy drive controller IC. For completeness I'm using DOS7.1, and a Celeron 300A system and a Qume 5.25" 360Kb floppy. ----------------------------------------------------------------------------------------------- (Osborne SD disks read/write OK for me in all of my IMD systems) So it would appear that I am still missing something. Perhaps it is something specific to the DP8473AV FDC, or some other PC hardware specific setting that "happens" to be set correctly by BIOS in most cases. IMD configures the FDC as per the original NEC 765 databook. It also sets the drive motor and select signals at port 3F2/372, the AT data rate at 3F7/377 as well as the DMA controller/setup... Anyone have any idea what I have missed? My main references have been the NEC databook, and the Phoenix BIOS technical reference manual ...

NCD firmware

by dgy＠DakotaCom.Net

Hi, I asked this on the REScUE list a week or so ago and belatedly realized *this* would be a better forum. So... Does anyone happen to have access to an NCD-19c/88K running firmware (i.e. boot ROM) more recent than 2.6.0? (this is displayed at the top of the screen during memory test/IPL; it is also visible from the NCD "console" once NCDware is loaded) Likewise, I am looking for boot ROMs newer than 2.6.1 for the NCD-19r (different beast). If so, I would love to get my hands on a copy of the ROMs (I can duplicate them if you are willing to loan them to me for 2 * mailing_time). I'd also be interested in new versions of the ROMs for the 14c (I'll have to see what the most recent version I have for these) Alternatively, if there is a repository on-line someplace that has these images... (?) I'd be willing to start archiving ROM images if there is a need (I have a few older versions -- though chasing down release notes for all of them may be a chore) Yeah, I know, they're all boat anchors... :> But, with a little TLC they seem to just keep humming...

It seem to be the same as the silicone grease that NAPA stores sell under their brand name. Many dielectric greases are not silicon based but may work as well to improve contacts of connectors.

Sorting large box of 72 pin SIMMs - looking for chip ID guide

by ethan.dicks＠gmail.com

Hi, I have a largish box of random 72-pin memory, but I can't seem to find a guide online that will help me differentiate the types of memory based on the manufacturer's chip numbers. I recall back in the day, one could look at the last couple of digits of the memory chip part number to tell FPM from EDO, etc. Unfortunately, two evenings of googlings has only found me consumer-level guides to help clueless PC owners tell SIMMs from DIMMs - nothing at the chip level.

Redux on sound-deadening foam

by cclist＠sydex.com

Just went through another printer with 1/4" of black sound-deadening foam attached to the insides of the enclosure in absolutely terrible shape. I found that warm soapy water is the easiest way to remove it--it just disintegrates into sludge when the water hits it. I'm thinking of replacing it with 1/2" styrofoam. The noise to be attenuated is high-frequency 1-3KHz from the printhead. Does anyone have any thoughts on this--leaving any sound absorption off is a little more than my ears can take. Thanks, Chuck

You can get special safe-for-plastic greases; they're used in the automotive industry to prevent plastic trim from squeaking, for example. However, although I'm sure it's not what Sony et al had in mind, I've successfully used silicon-based furniture polish with great success. I have monitors which have been cleaned and then lubricated with that a decade ago, and are still perfectly happy. My advice would be not to buy anything specially, if you already have something that seems like it will do. -- Pete Peter Turnbull Network Manager University of York

I have to say, there's very little way I could justify the use of kWh on either of the two projects, if the alternative is having the machine off. But for people wanting to do something with their classics, I assume the electricity has proven not to be a major consideration.

To give away: Complete Intel UNIX System V Rel 3.2 package

by joachim.thiemann＠gmail.com

Hello, (wow, the last time I posted here was in 1998...) I'm cleaning up a little, and figured someone here might be willing to take this off my hands (before I put this in the recycling bin, that is) This is a box from Intel Corp, around 1998, contains Bell Technologies UNIX System V/386 Release 3.2. The box contains 11 books (Introduction to System V/368, Using UNIX Vol I-IV, Software Development Vol. I-IV, Networking, and Integrated Software Development Guide (ISDG)) as well as install media: 28 5-1/4 floppies and what looks like a DC-600 tape. I have no way of testing the media. The original box says product code: UNX40PLATMNR1.0, Revision 01, build date 10/19/90. I picked this up when it was tossed out from McGill's EE department, I'm not sure if they ever used it. Contact me if you want it, but I would not ship it - it's a box o'books, effectively, quite heavy. I live in Montreal, Canada. Again, it's free for the taking, but if someone really wants to give me a C= 1571 for it, I won't say no ;-) Joe. BTW anyone heading to VCF East from Montreal? I'm tempted to go if I can hitch a ride (and contribute gas money, of course).

KM11 replica

by ggs＠shiresoft.com

I just wanted to let folks know that in addition to the KM11 replica, I now have several accessories available for it. They are a "light mask" and a set of 8 overlays. More information is available on my web site at http://www.shiresoft.com/products. For anyone who has previously purchased a KM11 from me and wants to "upgrade" to the "Delux" version, please contact me about pricing. -- TTFN - Guy

Thunderscan

by James＠jdfogg.com

> Has anyone else seen a thunderscan? Yeah, when they were new. The college newspaper I published on a Mac owned one. They were very popular as an inexpensive scanner solution. Back in the day anything that was "Mac compatible" was more expensive than the PC model, and scanners were horribly expensive to begin with. The Imagewriter provided all the transport mechanics needed and allowed for a less expensive scanning option when paired with the Thunderscan. The image quality wasn't as good as a real desktop scanner, as I recall.

PCI DSSI adapters; was [Re: FA: DEC RF-71 Disk Drive]

by compoobah＠valleyimplants.com

DEC DSSI VMScluster Installation and Troubleshooting Guide (EK-410AB-MG. D01) talks about all the different ways to cluster AXPs and VAXen using DSSI (but doesn't cover PCI, only EISA + proprietary DSSA adaptors). Evidently, DSSI clusters were used often enough. Seems that by this date, they were implemented mostly with HSDs rather than DSSI drives.

QNX, Useful applications

by mtapley＠swri.edu

All, regarding QNX, there must be a reasonable user base out there. The QNX on x86 guys have cranked more on the Distributed.net RC5-72 project than the NeXTSTEP/x86 crowd, and are still active. I also note the existence of a QNX on ARM client, which implies QNX ran on some ARM platform as well. Palm? To tie in a different thread, regarding "practical" applications for vintage computers, Distributed.net seems like a natural. It's not exactly Earth-shaking science at the moment, but it's a big problem that breaks naturally down into a lot of very small pieces, so it's something classic systems can actually practically contribute to. I would *love* to see a VMS/VAX client, and to my knowledge there are several VAXen on the net now doing not so much at any given moment. Do any of you VMS gurus have time and inclination to combine the VMS/Alpha and the NetBSD/VAX clients and let us put VMS/VAX on the charts? And of course, I don't know *why* no-one has put the MacOS 6-9 client back active. I actually have a copy of CodeWarrior, so let me know if you have time, ability, and inclination, but lack of CodeWarrior. We can work out a loan. Personally, I have inclination and CodeWarrior, but neither (really) time nor ability, though I'm trying to work on it. I don't suppose an 8-bit client is practical - I've never heard of a C++ compiler to 8-bit target - but it would be really cool to crack a block of keys on my Rainbow under CP/M-80. Sigh. Does anybody have any positive/negative experience with distributed.net that I should know about? http://www.distributed.net/ for more info. Hit "statistics", pick a project, and look for "mtapley at swri.edu" to see my meager contributions so far, or go straight to http://www.distributed.net/source/ to grab the public part of the source. -- - Mark NEW CELL PHONE NUMBER: 210-379-4635 2-way pager until end of March 2006: 888-733-0967 office is still: 210-522-6025

"party line" for terminals?

by legalize＠xmission.com

I purchased an odd terminal display (no keyboard) from ebay recently and it arrived today. Its manufactured by Westinghouse Canada and has 3 ports that look like DB25 female style and 1 DB9 style female port that says "party line". I'll post more detail later, but oddly enough this terminal monitor doesn't appear to have a keyboard port, unless it connects to one of the data ports on the back. What is the "party line" port and what's it used for? A search of the cctalk archives didn't yield anything. -- "The Direct3D Graphics Pipeline"-- code samples, sample chapter, FAQ: <http://www.xmission.com/~legalize/book/> Pilgrimage: Utah's annual demoparty <http://pilgrimage.scene.org>

PDP-8/L teletype interface

by sb＠thebackend.de

Hello everyone! I wrote here about my PDP-8/L a long while ago already. This is my current status: All instructions seem to work (only tried the simplest form, i.e. 5001). Core memory is mostly untested. The places I used work and retain their content. Examining and depositing works. AC, PC work: I can execute small loops using jumps and conditional skips etc. So as far as I tried it everything seems to be alright. Now I wanted to revive the teletype interface to load and try more complex programs and that is where I am stuck now: The machine has the M452, M706 and M707 modules. W076 was missing so I got a W076X from Vince that does RS232 (thanks again :-) as well. I don't have a real teletype. I used this small program to try and send characters from the switch register: 0000 7200 CLA 0001 7404 OSR 0002 6046 TLS 0003 6041 TSF 0004 5002 JMP 003 0005 5000 JMP 000 The program loops like crazy but nothing happens to the serial output. If I connect a oscilloscope to the data lines of the M707 I can see the input bits change as I push the buttons on the front panel and step trough the program. The input clock is there as well (so I assume the M452 is working) but no data stream comes out of the module. Writing this I realize that I didn't check the device selector inputs. I'll do that tomorrow. I know how to operate an oscilloscope and I have some experience with electronics but I'm not very good at reading logic and I only ever spent a couple days with this computer so I need some help here. Is there anything I have to look for especially? Next I tried receiving characters. I hook my PC up to the W076X and start sending more or less random characters. They show up on the backplane side of the W076X module and on the input of the M706 but no data comes out either. The clock input is low all the time. Two of the select bits seem to be low all the time even if I execute the following program: 0000 6032 KCC 0001 6031 KSF 0002 5001 JMP 0001 0003 6036 KRB 0004 5001 JMP 0001 Actually the above program completely hangs the computer. I stays in "run" state and on address 0002 whatever key I press. That never occured before. As you see I don't know too much about this computer. Am I using the right commands at all? I started reading the documentation and schematics (it is truly amazing how complete they are!) but I am not sure what to look for - what the signals on all the different "clear"-inputs of the M706/707 have to look like for example. Any hint is apprechiated! Sebastian PS: It's been a long day so don't mind me if I don't make too much sense...

URGENT: Data recovery assistance needed in New Haven, CT area (cctalk)

by woyciesjes＠sbcglobal.net

Hopefully there is someone nearby who can help. At work here, we need to recover some old data on Canon Magneto-Optical discs. I don't have them in my hand at the moment, so I can't give model details yet, but IIRC, they are roughly the size of 5 1/4 floppies. And to make things more fun, we can't find the drive that they were used in. Does anyone have one we could buy, or borrow? Or leads on who to talk to? And no, we cannot send the discs out, due to HIPAA privacy rules. The drive would need to be used here at Yale. Reply to me directly.

I snagged Multinet at work and I'm going to try it out this weekend if I have time. repost: has anyone tried the VAXstation 3100 ROM patches that are supposed to allow safe usage of >1.03GB system drives?

HIPPA

by compoobah＠valleyimplants.com

HIPPA is really not that much of an issue- you just need to have a signed agreement from all contracting companies (and, for that matter, employees of the office) acknowledging that the data is confidential and protected and . . . etc. etc. etc. All medical/dental offices should have a form (the same one that they use for the janitors works). That said, I would never allow a disk to go to anyone without one of the forms signed, even if it is "unreadable". I like $.07 insurance. . . Scott Quinn

Dead HP-9825A

by vp＠cs.drexel.edu

I have an HP 9825A with Opt 2 (24K RAM) which does not display the lazy T symbol on power up (dark display on power on). I have checked the PSU voltages and they are OK and have carried out the obvious tests to see if the problem is a dead display ([RESET] spc [EXECUTE] [RESET] beep [EXECUTE]) but nothing happens. Oh, the fan works fine, there are lights inside the tape drive slot and when I press the CAPS key the CAPS-LOCK LED turns on (and goes off if I press CAPS again). I would like to remove the second memory board (16K) just to be sure that its not a prob with it. The manual suggests that a dummy board was installed in the place of the 2nd memory board. Does that mean that the machine cannot work with one memory board? Also will I get a display with the tape board disconnected? Thanks **vp PS I have the 9825A Service manual, but this simply tells you how to disassemble the machine. In fact the troubleshooting flowchart essentially tells me that anything could be at fault.

"party line" for terminals?

by ken＠seefried.com

That brings back memories. My first consulting gig almost 20 years ago was with Delta Air Lines working on a system that would tie airline reservation terminals to Unix machines. If those terminals are indeed airline terminals, then they likely use ALC (Airline Link Control). It's a 6-bit, bisync, polled serial protocol derived from some older IBM protocol. The terminals talked to a concentrator, which then talked to the IBM mainframes running applications on top of TPF. My project was to replace the concentrators with Unix machines (which could talk to more than just IBM mainframes), with Stallion Technologies providing custom serial cards that could grok ALC. Good times... Ken

manually installing MSDOS...

by Watzman＠neo.rr.com

Ok, first, the "MS-DOS" that you want to use is "MS-DOS 7", "extracted" from Windows 98SE. This is easy, just find a 98SE system and format a bootable floppy. The utilities are in C:\Windows\Command of the 98SE system. [additional MS-DOS utilities are on the Windows 98SE CD]. This version of MS-DOS ***WILL*** recognize FAT32 partitions. Also, there was an update to FDISK in May of 2000, you want to get that, it's available from the Microsoft web site. It will recognize drives up to 137 gigabytes. There is no easy way to manually install, but you can boot from a DOS bootable CD and run SYS from that. After you make the "MS-DOS 7" floppy (above), use that floppy as an "image" in making a bootable CD. That should get you where you want to go. [Note, the full set of DOS utilities won't fit on a 1.44MB floppy, so be sure to put them on the CD so that you have a place to copy them from.]

Best/Cheapest source for FPM memory (4mb/8mb)

by Mzthompson＠aol.com

On Sat, 11 Mar 2006, From: Gavin Thomas Nicol <gtn at mind-to-mind.com> wrote: > Apart from EPay, are there any good sources for smaller-sizes of > <80ns FPM memory out there? Assuming you're referring to the standard 72 pin SIMM, my best source is the roughly 6 gallon bucket out in the shop that is almost full of nothing but 4mb/8mb sticks. No doubt that some of it is EDO and there is parity as well as non-parity. I got tired of sorting anything less than 16 mb and the bucket does the trick. Mike

old 8088 system course++

by ericmac＠swissinfo.org

Thanks for the responses to my question. I was able to continue searching >from the tips and I'm pretty sure what I was asking about must have been >from NRI. From what I came up with it also looks like that is long gone. I am back to my original problem. How to learn the fundamentals of the 8088 or 8086 ... and then to continue from there to the larger chips. At the moment I'm concerned about the 8088 or 8086. I have found resources that introduce those chips in a very clear, step-by-step way and include the plans for building a trainer. But they all stop short of interfacing FDDs, HDDs, etc. Would anyone know how I could "learn-by-building" an 8088 or 8086 system complete with drive interfaces, etc., starting with the very elementary aspects of learning the chip architecture and hardware on through to systems with FDDs and HDs and video, etc.? Thanks again. Gary "I think it was about 15-20 years ago there was, I believe, a self-study course put out by some company for learning the hardware (and I think some aspects of software, i.e., DOS) of computing at that time. The course came with an 8088 computer that, if I recall correctly, one built and "learned by doing." I'm pretty sure it was not a Heathkit. I have searched everywhere and have not come up with anything. Does this sound familiar to anyone? Any information would be helpful. I'm trying to track one of these courses/computers down. Thanks!" _______________________________________________________________________ Your Site for Swiss Maps: http://www.swissinfo-geo.org/

IBM Mainframe guy in Chile is selling of his entire stock (or offering it)

by jwstephens＠msm.umr.edu

The sad thing is that he had a 360/40 (2040) cpu which he now says is in bad shape that is for sale. $25,000 gets you a 40' container of really nice stuff though. i had asked him if he had a full mainframe at one time and he said he did not. now, if it is what remains after his ebay auctions, there won't be much left, sad to say. But a 360 would probably be a steal at 25K, unless someone knows where one is for less. Maybe dkdk will swoop in and buy the parts he does not already have of the 360, and it will end up complete somewhere. Hope he is acquiring for a museum somewhere, or his pile comes to view in public, it must be quite nice by now. jim seller: alejoelectronic specific auction: 8782204551

modern media in vintage computers

by chrism3667＠yahoo.com

weve all seen the use of (typically) compact flash cards as mass storage in classic stuph. Are SD cards as adaptable for this purpose? I remember reading somewhere that the flash interface is essentially IDE in nature. Does this apply for all types of cards? And if anyone could point to an article/link/book on this type of crazy stuph, Id sore appreciate it. Nuts and Volts had an article on building a micro controller based mpeg player (with cflash storage) so maybe I should take a look at that. __________________________________________________ Do You Yahoo!?

PDP8E on Ebay

by cheri-post＠web.de

Don't worry Bob, this guy is just trying to make money. He didn't sell it the last *times* which is no wonder, as 3000 EUR and 2000 EUR seem a bit too much in my opinion. He said in french the he won't go below 1500 EUR. He kept on saying that for those who think that they should wait to get a cheaper price....he wouldn't do it. And as he said that he would put back his 8/e into his basement if nobody bids....not a problem for me as long as this 8 isn't being scrapped.....

Things may have changed by the time stuff shipped, and you certainly cannot put a SCSI drive on a DSSI bus (or vice versa) but clearly the two busses are fairly close at some level.

Blower/airflow sensor needed for BA32

by bob＠jfcl.com

The BA32 is the baby VAX BI chassis used in the 8200/8250/8300/8350 systems - I have an 8250 (it'd be an 8350 if I could find another CPU :-) that has some problem with the cooling. The blower speed seems to vary all the time it's running, and it's constantly speeding up and slowing down. The system wil run for about an hour and then trips itself off, presumably either because of airflow or overtemp. Can anybody tell me if the blower speed is supposed to vary like that? Does anybody have any maintenance prints for the BA32 blower control? Anybody got any spare parts they're willing to sell? I spent a long time putting it back together after it'd been stripped by a scrap yard, and I've actually got it to the point where it will boot VMS now, so I'd really like to fix this last problem. Besides, it's a really cute little system - I believe it's the smallest VAX BI box around. Thanks, Bob Armstrong

I > was wondering if the picture was showing the DSSI style sled on it. > My DSSI slots are full, but I gather the TKZ70 tape drive isn't very > useful... maybe I could put another drive in that bay? If you have one of the VAX 4000 BA4xx series machines, it's very easy - just slide out the tape drive and slide in the disk drive. Fully documented in the BA400 docs on either Manx or bitsavers, can't remember which. DEC used to sell a spacer plate to take up the extra 3/4", but you should be able to get by without it. Smaller MicroVAXen are different, haven't seen one personally so I can't comment. Does anyone know what the DEC number is for the DSSI-configured drive sled for BA4x0 (as used on ISEs? Trying to find one, but I can't give a specific model # which makes it difficult) Question 2: has anyone tried Moeller's ROM patch for KA41-43 to support >1.03 GB system drives? Looks good, but as I'd have to bribe someone with access to an EPROM burner to do it for me I want to check it out first please respond on-list, my E-mail seems to have started diverting incoming messages direct to the bit-bucket.

I guess I should have asked this before asking for a 5.25" floppy drive

by wbblair3＠yahoo.com

Can Apple II disks be copied using a PC 5.25" drive and/or can downloaded images of Apple II system disks be written to a PC drive? I'd suspect that because of the unusual format of the Apple II floppies that special formatting/copying software would be required to do this.

New Big Iron Acquisition - IBM Tabulating Equipment

by tony.eros＠machm.org

The Museum of Business History and Technology in Wilmington, DE is proud to announce the arrival of its latest little bundles of joy, an IBM 405 Accounting Machine and an IBM 513 Reproducing Punch. The 405 weighed in at a hefty 1000 lbs, while the 513 is a relatively svelte 400 or so.

The systems came with 405 & 513 schematics -- blueprints, really; 405 & 513 service records and a 513 CE guide. The 405 also has five programmed plugboards (the system was originally owned by a liquor distributor in Madison, WI) with various sales reports, as well as a blank board. Both machines are in very rough condition, as you can see from the pictures. As it turns out, I spoke to a guy in Green Bay a while back (prompted by a mail list posting) whose brother was selling some property. On the property was a barn; and in the barn was, you guessed it, old IBM tabulating equipment. The plugboards even had hay on them! On the other hand, the wiring bundles actually look pretty un-nibbled by various critters, so go figure... What's next? Any retired IBM customer engineers out there with an interest in helping to restore these machines? Restoring the 405 looks to be an enormous task, but with a very high coolness factor. Does anyone know of another organization that has restored one of these?

I was able to purchase a brand new one from softhut.com in January. It was shipped over in a new batch then. Kelly

CP/M sysgen question

by Watzman＠neo.rr.com

Sysgen neither copies nor doesn't copy any specific components. Basically, the DR standard Sysgen for CP/M 2.2 copies the contents of the first two tracks (52 sectors of 128-bytes each) to and from a buffer at 900H. It doesn't know or care what components are present in those tracks, it just does a blind copy: 52 sectors (128 bytes per sector, two tracks of 26 sectors each) to and from memory at address 900 hex. [This address was different [lower] in some earlier versions of CP/M]. Now that was the standard Digital Research SYSGEN. If you are dealing with an OEM system or any system that used any flavor of 5.25" media, then all bets are off. In such systems the entire methodology for system generation, booting and copying the boot code were entirely up to the OEM and could be extremely different from the DR standard (which was both simplistic and quite restrictive). On my own implementations for the Z-100, I put the OS and the BIOS onto the data area as files OS.SYS and BIOS.SYS (which did not have to be either contiguous or located in special areas). (For MP/M-86, the OS consisted of about a half-dozen different modules.) What I put into the system tracks was an OS loader program that could actually read files using the directory and FCBs. And for writing and copying that, I created a program called "WRITLDR" (write loader). The loader had a CP/M-like boot sector and bios of it's own, but since the loader itself was relatively small, the loader's bios could be relatively huge, allowing for the complexity required to deal with systems with a large number of bootable disk formats.
