You've got a tape from the IBM Magnetic Tape SELECTRIC Composer. Attached is an IBM Journal article describing it in detail.... Lyle On Monday 17 November 2003 23:42, Zane H.

WHOA ... those machines are SO RARE. In fact I haven't EVER seen a Mag Tape Selectric Typewriter or Mag Tape Selectric Composer ... and the Composer was made in much smaller quantities than the MT/ST. (I do have a Composer, an Electronic Selectric Composer or ESC, and a Mag Card Selectric Composer or MC/SC ...) I believe the MT/ST was the first significant word processing device, and I would love to find one, but I'm not sure any exist any more. If only one ever turned up, I think it should go to the Computer History Museum. Does anyone know of one? Norm

Or over the IEEE-488, in the case of PET and B-series machines, etc. (or over a C-64 or VIC-20 IEEE cart as well). In the case of the 1541, it is a 6502. In the case of some of the older drives, a 6502 and another 6502-family processor, like a 6504 (same features, but in a package with a reduced pin count and a smaller accessible address bus). There was a piece of software that made things easier, commonly called the "DOS Wedge", but it was entirely optional. It patched the routine in low memory (around $0070) to intercept interactive commands that started with certain characters (like ">") and, in effect, extended BASIC to let you do certain disk operations like directories, format and rename commands, and check the error channel. More or less, it was a soft-loadable version of the routines that BASIC 4 had in ROM. But it still wasn't a DOS. -ethan -- Ethan Dicks, A-130-S Current South Pole Weather at 19-Nov-2003 23:10 Z South Pole Station PSC 468 Box 400 Temp -40.6 F (-40.4 C) Windchill -65.2 F (-54 C) APO AP 96598 Wind 7.3 kts Grid 027 Barometer 677.1 mb (10735. ft) Ethan.Dicks(a)amanda.spole.gov http://penguincentral.com/penguincentral.html

How about variants of this, such as Diversi-DOS, and I'm sure others but offhand I can't remember their names. Apple ProDOS What about the Iigs OS? Should that go under 6502, or 65816?

RM-DOS This was a multi-user MS-DOS lookalike for use on Sord M-343. It supported up to 4 5.25" HD floppies (not compatible with MS-DOs) and a 10 meg harddisk. It could read MS-DOS HD floppies. The Sord could also run MS-DOS 2.11 with floppy HD support.

Has CDOS been mentioned yet? Multi-user DOS for one of the 808x processors.. In a sort of reversal of the what-OS-for-this-processor, add "BOS" as a multi-user operating system ("Business Operating System") that ran on lots of various platforms (standard PC hardware from 8086 up, PDP-11, S100, Sirius 1, RS6000, Microfive are just the ones I encountered.) I'll try and dig out a list of platforms if I can find an old enough manual at work.. It is an interpretative OS for running standard business applications (sales ledger, purchase ledger, etc) on a wide variety of platforms - the data *and applications* could be copied across platforms with no conversion or recompilation necessary. It needed no other operating system or software to be installed on the hardware, so was a true OS, complete with all the development tools you'd expect. It's still going strong (I work for a reseller) although current versions nowadays tend to run within an existing OS (mainly DOS, Windows and Unix). http://www.global3000.com/platform.html Oh, and if anybody in the UK is interested in an old COMART machine, that's probably still got this loaded up on it, there's one burried at the back of the filing cupboard that I could probably get released... We'd have more, but unfortunately my boss is a bit of a chucker... he took two 11/23 clones to the tip a couple of years ago while my back was turned.. :-( Rob

It was the "Stand-Alone BASIC" that was the "inspiration" for the MS-DOS directory structure. Then the early Mac directory strusture was based on ("improved" on?) the MS-DOS directory structure. (unidirectional linked list of block numbers, using 12 bit entries, reserving blocks #0,1 for system, and putting the linked list before the directory entries, immediately following the boot record. The similarities are too much to be coincidence, and it is CERTAINLY not because that was the "bes possible" way to do it!

Hitachi HD6309: NitrOS-9 It is an OS-9 rewrite that uses the extra functionality of the 6309. -- tim lindner tlindner(a)ix.netcom.com Bright

Well, there will be a version for the 6809. The back porting has not been completed yet. -- tim lindner tlindner(a)ix.netcom.com Bright

Apple P-system / Pascal (this is a complete separate OS from DOS & ProDOS) What about version numbers? It might not be practical to list every "release" version of every OS, but how about at least the latest/last "official" release version number? - Bob

It was built into ROM on all disk devices that implemented it. BASIC 4 machines (PET 8032, PET 4032, etc.) had some extra commands (compared to BASIC 2 machines, and the C-64 and VIC-20) that took care of some of the details, but the traffic between the computer and the drive was identical... For example: On a BASIC 4 PET, you could type CATALOG to get a disk catalog. On all machines, including BASIC 4 machines, you could load the special file "$" to get a catalog (i.e., "LOAD "$",8"). The drive itself knew about the directory format, media capacity, what a sequential file was, etc. The PET/C-64/VIC-20 just knew how to open a device (printer, disk drive, modem, etc.), how to move blocks back and forth, and how to close the device. It's a very different model than most computers use. There was no real "DOS" on the CPU, just low-level device access routines. There are DOS version numbers for devices, but they tend to be related to how new the drive is, and any details about media and capacity. I know of only one "upgrade" in the Commodore drive family - the original 2040 drives had a slightly buggy DOS for which a new set of ROMs were available, making it, in effect, a 4040 drive (the low-level format changed slightly, eliminating one block per track for one of the recording zones). There were version numbers like 1.0 and 2.0 for the 2040/3040/4040, up to 3.0 for devices like the D9060 and D9090 hard drives. It's probably too much detail for what you want, but the Commodore drive scheme isn't like the other microcomputers of the day, and it bears some explaining. -ethan -- Ethan Dicks, A-130-S Current South Pole Weather at 18-Nov-2003 22:30 Z South Pole Station PSC 468 Box 400 Temp -37 F (-38.4 C) Windchill -66 F (-54.4 C) APO AP 96598 Wind 8.4 kts Grid 034 Barometer 676.6 mb (10756 ft) Ethan.Dicks(a)amanda.spole.gov http://penguincentral.com/penguincentral.html
