Excellent. Thank yoy, Al! I will download and extract them where I can. I have written a program that can decode LSI-[24] file systems and file storage format. I'll inform the list when it's done. Al: You post was also addressed directly to me, but I did not receive it. As far as I can see it never reached my mail server. /Lars Hamr?n

OT - Simple Read / Write Detection on Individual SATA II Drives

by jhfinedp3k＠compsys.to

I realize that they don't qualify for the 10 year rule, however, since I will be using them to run Ersatz-11 to run RT-11 software from 1985 which does qualify, I hope that this question is not too OT. Up until 10 year ago, even drives for a PC had individual LED circuits which provided a status when a read or a write request was being processed. Now, I can't find any drives which have such an LED. Tony (any anyone else who may know the details), perhaps you have the hardware knowledge as to what might be required to add a circuit with an LED (or anything else that would do the job) which would provide a status when a SATA II drive is being accessed. Separate read and write would obviously be even better, but a single LED would be more than adequate. My concept would be to modify the existing cable between the motherboard (or the controller) and the drive so that an LED could be wired in with the appropriate hardware. The wires on the LEDs should be long enough to allow them to place the LEDs outside of the case so that the user can watch then as needed. Even better might be really long wires that would allow the LEDs to be attached to the monitor. From what I know of LEDs, the current that they draw would not be a problem with wires that are many feet long. Can anyone suggest if this is a feasible project? I realize that the motherboard which has a display LED status capability for all hard drives is available, but then I don't see the status for an individual drive (I have 3 SATA II drives), let alone if the request is a read or write - assuming that it is possible to show read and write separately. Plus if the LEDs were attached to the monitor, that would be much more convenient. I actually have such a software display on my monitor right now for each of my UDMA 100 drives which is really helpful, but I don't know of any software which is set up to do that with current systems Sincerely yours, Jerome Fine

DEQNA/DELQA cab kit with DEUNA/DELUA?

by tiggerlasv＠aim.com

As far as I can tell, the pinouts for the 20-pin BERG connectors on the DEQNA, DELQA, and DEUNA are functionally equivalent. (The DELQA uses 2 extra lines, but those will most likely be ignored, particularly if you're using a media converter, to translate to RJ45. . .) You can also use the DELQA / DEQNA cab-kits interchangeably, for basic ethernet operations on the PDP-11. . . As info. . . .

DEQNA/DELQA cab kit with DEUNA/DELUA?

by oldcpu2＠rogerwilco.org

For all the DEC fans here, since I haven't been able to locate a print set for the DEUNA, I was wondering if the cabinet kit that goes between the UNIBUS DEUNA board and the 15-pin AUI connector is functionally the same as the cab kit for a QBUS DEQNA / DELQA? In other words, can a DEQNA / DELQA cab kit be used with the DEUNA ethernet controller, or are they different (pinouts, etc.)? I'm trying to organize all of the parts I'll need to get a VAX 11/750 online, once I finish up the power supply troubleshooting and get the system operational again. Thanks. Jared

BYTE magazine article index

by rcini＠optonline.net

All: I found a 10-year-old thread from this list discussing the existence (or lack thereof) of an on-line or off-line article index for the entire BYTE magazine series. From the thread it seemed that one didn?t exist at the time. I have the complete series from issue #1 to about mid-1988 and I find it difficult to zero in on particular topics. If I had a searchable article database, I could then make better use of my archive. I?ve done some googling for an index but haven?t come up with anything concise yet. Is anyone aware of an on-line index for BYTE?

installing more memory

by aliensrcooluk＠yahoo.co.uk

Hi, i have installed extra RAMinto my Amiga 600 before (in the trapdoor) which plugs in straight. However, plugging the extra RAM i just got for my laptop (Dell C610) requires it to be inserted into the slot at 45 degrees and then moued parallel (flat) on the pcb until you hear a click! (thats what it states in the C610 manual) Who's idea was that and are there any pitfalls i should be aware of? (other than damaging the connectors) - Andrew B (via mobile)

I found some links to wire in a PC power supply, and I yanked one from one of those book pc's. This one even had an ethernet interface in it! Very unique machine - I got through fleaBay a Strongarm 200mHz CPU board, and the machine already had an HD and a CDROM. Also from the UK i got a 2nd "slice" to make it a double-decker, and a ROM+RiscOS upgrade. I quickly lost interest in that, though.. but it was an interesting machine. I ended up selling it on fleaBay for about $200 or so to someone here in the states. I'm sure many others on the list as as I am - I like to acquire things, learn them, and then pass them on to someone else, and I've done that with SGI's, Sun's, HP unix workstations, I had a DG with AOS on it (never learned THAT though) as well as playing with Hercules IBM mainframe emulator for MVS 3.8 and VM/370 R6 Tony

Not expensive. Can't get much cheaper than effectively free for a well regulated, high current DC power supply using a modified PC power supply that isn't otherwise being used. Plus, the idea of using tubes with 5V filaments instead of 6.3/12.6V reduces the competition with typical audio tube customers and makes the use of a high-current 5VDC supply possible. For the homebrew 1.5A adjustable DC supplies, I use LM317HV based units plugged into a homebrew chassis where I've mounted a range of three different inexpensive, surplus, multi-secondary transformers with output voltages ranging from 70VCT to 12.6VCT. The chassis has binding posts for each secondary and I just plug the banana plugs for the various inexpensive LM317HV adjustable DC supplies into whatever AC outputs most closely match the DC voltages I need at the time in order to reduce the power dissipation requirements of the LM317HVs.

Same deal - I gotta have SOMETHING set wrong... it still comes back to saying that java isn't enabled. Also, when I go to www.wagerline.com, the mouse-over drop-downs aren't visible, as they are overlaid by the flash anim. I used the adobe version - should I have selected on of the others instead?

N8VEM Disk IO peripheral

by lynchaj＠yahoo.com

Hi! A while back I mentioned the N8VEM SBC which is a new Z80 home brew project designed in the "classic" late 1970's style. There was some discussion about the merits of using RAM/ROM drives versus "real" drives like IDE hard drives and floppy disk drives. Work continues on the N8VEM project to include supporting "real" drives. The SBC PCB and the ECB backplane PCB are basically done and available for builders to make their own home brew Z80 CP/M computer. The next project is an ECB bus monitor, which is basically done awaiting the PCB order, and the next project is the Disk IO board. I am currently working on the Disk IO board as my main activity. The Disk IO board is comprised of two parts; an IDE interface and a FDC interface. The IDE section is basically done, works just fine, and is supported in the CBIOS. No doubt it could be improved with some TLC but it works well enough for my purposes. Like the rest of the N8VEM project, it is comprised of "standard" commonly available DIP parts with no custom or programmable elements except for the SBC EPROM. I am currently working on the FDC section and making some progress thanks to some wise and very helpful persons (you know who you are!) The design exists, is based on a NEC 765 reference design at the ALPACA project, and a working but obviously still in development prototype board is on my bench. As part of the development, I am writing a "disk monitor" program to exercise the i8272 FDC chip. Currently, I can use it to read sectors from a 320K IBM PC MS-DOS formatted 5.25" floppy disk in a Tandon TM100-2A minifloppy drive, print status, dump sector memory, etc. If anyone would like to join in the development of the Disk IO board, please contact me to discuss. I am making slow but steady progress but am sure having another set of eyes to review and write code would help a lot. This would be a great way to make your own Z80 CP/M home brew computer WITH "real" drive support. http://groups.google.com/group/n8vem Thanks and have a nice day! Andrew Lynch

CPT 8000

by gsimpso3＠bellsouth.net

Hello Adrian; I read a thread from 2004 on classiccmp.org's website about your CPT 8000 and wonder if you still have it? If so I may be able to help you out with any missing parts, program disks, diagrams, etc. just for the price of shipping. I used to service the machines for the local vendor from 1980 to 1990 and rescued a pile of parts and documentation that were headed for the dumpster when they were made obsolete by the PC in the late '80s. I even managed to save several intact machines. The CPT 8000 and its descendants were quite advanced for their time and had features that CPT's competitors (IBM, Wang and Lanier) couldn't come close to matching. I haven't fired my 8135 up in quite a few years so I'm not sure if any of the software floppies are still readable. All my program disks may already be unreadable. --Gary Simpson

Available for pickup: IBM hardware, FC SAN

by pat＠computer-refuge.org

I've got access to some IBM H50 systems that are being retired from work, with 4x332MHz processors, 3+GB ram (whatever the max is, 3.25 or 3.5GB I can't remember), some disks, and a 10/100 NIC. The disks have been erased, but they'll run up through AIX 5.3 I think. I'm not going to ship these because of weight, but shipping one or two parts from one is probably doable. Cost will be not unreasonable, but not free. :) I can hold onto them for a week or two probably, but not much longer than that. I'm also try to rid myself of my old 1Gb, MTI Fiberchannel gear. I've got a switch or two, and several 12-disk (1.6") 3U JBODs with 36GB and 50GB 1.6" tall FC-AL 1GB disks. I could pull and ship disks from this if you want them in multiples of 12, but I don't want to try to ship this either. These will probably be around for a month or so before I have to do something I don't want to with them. :( Make offers.. Also, if by any chance, someone is interested in driving here and picking up a frame or 3 of IBM SP nodes (quad 375MHz POWER3-II thin nodes) or an E10k, let me know... These are in West Lafayette, IN, USA (47906). Pat -- Purdue University Research Computing --- http://www.rcac.purdue.edu/ The Computer Refuge --- http://computer-refuge.org
