Apple LWPro parallel port?

by jhellige＠earthlink.net

>The other thing to consider is: Will OS X run at a useful speed on her >computer? Does the new versions of Photoshop require more RAM and / or >computing power? I just finished an install of OS X on a Beige G3/300 with 192MB RAM and it seems to run fine. I'm doing the initial testing on the G3/300 before installing it on the newer G4's we have. I installed it over the top of a current OS 8.6 setup and in fact, this email is being sent from Outlook running on 'Classic' under OS X. The install went painlessly, the speed is acceptable and it was quite simple getting the network settings put back to where everything worked. OS X ships with 3 CD's, one of which is OS 9.1, which I had to upgrade 8.6 to prior to installing OS X. 9.1 is what it actually uses to run 'Classic' applications. BTW, for those familiar with NeXTstep, it's easy to see the lineage behind OS X. They even kept the spinning multicolored pinwheel while the system is loading. Jeff

Apple LWPro parallel port?

by CARL.P.HIRSCH＠sargentlundy.com

Everything past the early PowerMacs is PCI, not NuBus. I'm going to agree that there's no compelling reason for her to upgrade to OSX. Hell, Adobe and other major vendors aren't going to have their apps carbonized for a few months yet. OSX is not essential even on the newest G4 until there's applications that can take advantage of its next-gen capabilities (i.e. multithreading for multiprocessing, integrated G4 acceleration). If she were to upgrade to OSX she'd still be running the majority of her stuff in a "Classic" environment window. If she decides she's absolutely got to keep using this localtalk printer after LocalTalk support is dropped, perhaps she could use a LocalTalk to EtherNet adapter. Assuming the software will support such a thing. Once ATM and Photoshop and Freehand and Premiere and InDesign are OSX-native, look out!

Hi all, My mom has the following setup: - Beige G3 minitower - Apple LaserWriter Pro 600 - OS 9.1 The printer and Mac are connected via LocalTalk. (This printer requires AppleTalk.)

The printer has no Ethernet capability, but it does have a parallel port in addition to the LocalTalk port. The questions are: Is there any sort of hardware/software conversion kit that would allow the Mac to use that parallel port if LocalTalk becomes unavailable in the future? Does anyone have any experience with running OS X and making it play nice with legacy hardware like this? Also, do they still make LocalTalk PCI cards, and if so, is there any chance that the drivers would work under OS X?

My ZX80 came with a ZX81 16K RAM pack and it works fine; ISTR physical differences aside the only real difference between the 80 and 81 was the ROM anyway, so by the time you'd bunged a 81 ROM in your 80 you ended up with an 81! The ROM even came with a 81 keyboard, overlay or real keyboard; can't remember which.

My first suggestion would be that, unless she has a specific reason for upgrading to OS X, she should stay with 9.1. Like all Version 1.0 items, OS X is going to need a few things worked out and will likely be adopted immediately by: a) developers, b) hard core geeks that just have to have the latest and greatest thing released, c) people that don't know any better and give in to some form or another of pressure to upgrade. She'd be better off waiting for it to mature a little bit, especially if she is just a casual user. As for the serial ports, since the Beige G3 is a supported machine, I would thing that it's serial ports would be supported as well. The only G3 or newer system not supported by OS X is the original G3 Powerbook. Jeff

Well, they would really all be the same network -- they'd be all one collision domain (any packet or collision appearing on one port would be seen on all the others.

Partitioning segments deliberately, eg to lock out a faulty host -- maybe one that's jabbering, or responding to things it shouldn't -- or an intruder. Monitoring traffic levels (counting packets, octets, collisions, etc). Monitoring traffic types (unicast packets, multicast packets, broadcast packets). Keeping a list of MAC addresses seen. Since all this is usually done by talking to the repeater (or whatever) over the network, the repeater itself has to have an IP address, and so there are ways to set that up (setting it by hand, or telling it to use bootp/dhcp) or upgrade the firmware, or set passwords for read/write operations. > I'd think so too, but I heard on Usenet that old repeaters (the kind which > actually call themselves repeaters =) could slow down modern networks. Don't > ask me how, though. I don't see why, if you're talking about repeaters. Old switches might well be slow, since they work on a store-and-forward basis. A repeater ("hub") works on the bit level; a switch works at the packet level and looks at the type and addressing of each packet before passing it on. Newer switches use ASICs to do this in hardware at wire speed, older ones use more conventional processing (or a combination). > >> What does partitioning actually entail? > > >See above.

Segmenting isn't, it's just a way of making one big(ish) hub do the job of a few smaller ones. -- Pete Peter Turnbull Network Manager Dept. of Computer Science University of York

Yes, you can do that and the perfomance is very good on the K2-350 box here at work. I use teh 3.5" loaded one to install windows and apps as it's faster than 4x CDrom and since some systems here dont have cdrom at all it really beats floppies or sucking it down the 10mbs eitherpipe.

Yah, the ZX80 couldn't think and talk at the same time so it blanked the screen while it was processing! In the ZX81 this was known as FAST mode, with the slower SLOW mode being able to do both. However, this still meant that in SLOW mode the machine was 4 times slower than in FAST!

SCSI SCA connectors

by JRichardson＠softwright.co.uk

OT, sorry - but are there any SCSI fans on the list who know anything about the SCSI SCA standard? If so can you dro me an email off-list if you know the answer to the following... I've got a couple of drives with SCA connectors and adapters plugged into them to bring them out to the more normal 68-pin connectors. There's a bunch of inline resistors on each adaptor which I'd like to know whether they are terminators or just something that's needed when connecting an SCA device to a normal SCSI bus. Both drives work together happily despite the resistors (have been doing for the last 2 years anyway) which surprises me if those are terminators, but nothing works if I try to chain anything else onto the same bus which makes me wonder... ps. one of the drives is 6 years old, but not ten - so take notice of 60% of this email or something :-) cheers Jules

Need Tandy 6000 Keyboard

by claudew＠videotron.ca

Is this a similar keyboard then the one from a TRS80 model 2000? Looks a lot like the same on the photos I have seen...and since the machine are from a similar "era"... If thats the case, I hooked up a more recent Tandy TX (83 Keys?) keyboard to an old TRS80 model 2000 and all works fine...the pinout on the connector is just not the same (I made an DIN adapter plug so I did not have to modify the TX keyboard)... I suspect this might also work fort machines like the TRS80 model IVP...and similars...

They all seemed to be remarkably similar inside, and by the time I was about 14 I got to be reasonably good at fixing them. My first "video monitor" was a cast-off 405-line 14" 'portable'. I stripped out the tuner (it was a turret tuner and almost every segment was broken) and some of the RF valves. It had a series heater chain so I added a few high-wattage resistors to make up for that, and tweaked the circuit a bit to handle the video from my first Exidy Sorcerer. -- Pete Peter Turnbull Network Manager Dept. of Computer Science University of York

Repairing a TK50 tape drive?

by family.entwisle＠btinternet.com

Woah, just stepped over the threshold from reading to contributing - even if it's only a question :-) I've a TK50 drive that I'm trying to get to work with my Vax. After discovering that it didn't work (the tape never wound itself out into the drive) I took off the cover. There appears to be a piece of stiffish tape connected to the central spinny bit (okay, I know stiffish, and spinny bit aren't the most technical of words! :-), but the other end appears to have been chewed off. I presume this would have the task of extracting the tape from the cartridge. Is there anyplace I can get spares for this part (in the UK), or instructions for constructing something similar myself (I've got a few sacrifical tapes while I experiment). I'd be grateful for any ideas. In fact I'm intrigued how the things meant to work! Cheers, Duncan.

HP 9845s?

by RebelTerry＠home.net

Hi, I'm new to the group. Does anyone have any information on the old HP 9845 desktop computers, specifically, if any working units still exist? I have manuals and a bunch of old software, including some extremely high-end games, both on 8" floppy and on tape. I'd love to at least be able to pull off some listings or get some of the data transferred to a current medium. Thanks. RT

i286-Mainboard

by mapr0003＠stud.uni-sb.de

Hi, I have a 'Morse Technologies KP 286HF' mainboard with an AMD-Processor - the board works, but I don't have the slightest idea about the jumper settings ... I put 4 MB in it, but it only recognizes 640Kb and I assume, that for clocking it to 12Mhz the (not available) Turbo-Button should be pressed ?!? For any hints or links to manuals I would be very glad ... Cheers, Mario

I don't know but the drive on the 520 is 5 1/4" and I think you said that your disks were 8" so that won't work. Besides my 520 seems to have problems. What kind of drive were your 8" disks recorded on? The HP 9885 and 9895 are very different. FWIW I have both. I'd guessing that the best way to read your disk would be an one of the NEWER 9000 series 200 or 300 machines such as a 9836. How many disk do you have that need to be transferred anyway?

HP 9845s? (And an original IBM PC.)

That's what some of the other HPs do. xx will be an id number assigned to that ROM and yy will be the number of the routine in the ROM. XROM of courxe means eXternal ROM. XROM xx,yy is how HP usually encodes the call in memory. If the ROM is present then the routine name will be printed (or executed in the run mode) otherwise it prints the XROM message (or halts with an error and displays the XROM numbers in run mode). I have plenty of 9845 ROMs, I can probably loan you what you need. Joe

I actually came up with an HP transceiver that proves my own point invalid. It's about the size of a zippo cigarette lighter, but a little thicker. It's a model# 28685B Ethertwist transceiver and it has dip switches to enable SQE, Link and Loopback test as well as use of a long cable. It also has 6 status LEDS near the 10base-T connector. I do have a small 5-port hub that isn't much larger than some of the AAUI transceivers I have though. Jeff

I just picked up a complete Sparc 10 system and I am having some video problems. When the system boots, the video is all ripped and looks like it wants to be in two columns. It seems to be in the wrong video mode. It does the same thing with both the mono monitor and color monitor I have for it. Popped the cover and it has a SUN GX video option board installed. Any idea's? Thanks, Brian.

Well, that last "ghetto blaster" spam was interesting in the fact that the sender made no attempt at all to hide their identity, or to relay through open third-party servers. Because of this, I believe it may just have been sheer ignorance on the part of bitways that turned them to the Dark Side of the 'Net. I've fired off a LART to mediascape.de, which appears to be the upstream provider for the company that did the deed. I will know shortly if this is true.

(I've used it with Linux) The closest thing to CAP for Windows would be PC-MACLAN from Miramar systems (www.miramarsys.com). There is also, of course, Thursby's Dave which whould give you Windows networking on the Mac. If we're talking just printing, then you might want to look for one of the old 'lpd' packages for the mac, though I'm not sure how the Windows boxes would fit in. Personally, I'd consider moving the LaserJet to a Linux box running netatalk (like CAP, but nicer) and possibly also installing a LocalTalk board. As an alternative to the LocalTalk card, use a second system (LC III or IIsi) with a minimal system running Apple's LocalTalk Bridge. <<<john>>>
