Reply - Re: Boot Disk Needed for Kaypro 2X

by laptoplarry＠gmail.com

Frank, Thank you for the information! My original plan is/was to retrieve my Compaq Portable (my wife buried it in a closet) to create a boot disk...only to find that I could not locate the MS-DOS boot disk for the Compaq?!?! While in the closet, I also retrieved a MacPlus that booted A-OK from a removable hard drive...except I could not find the mouse! Mac no mouse = no go... So, I have no 5.25 360K drive available to create a boot disk for either the Compaq or the Kaypro :-( I'm now wondering if I can find a SCSI 5.25 low density drive to attach to the portable hard drive of the MAC to create a boot disk for the Compaq. >From the Compaq's DOS I'd be able to create the boot disk for the Kaypro using the usual tools. Of course, I'd have to locate a mouse appropriate for the MAC... I guess the ideal thing would be to find a drive and controller for my "modern" machine. I'll check out the leads you gave me. Hopefully some kind soul will send me a bootable Kaypro disk and/or a MS-DOS disk on 5.25 360K media. Hey! Ain't this fun! -Larry ... -- This is not an automated signature. I type this in to the bottom of every message. Larry, Go to _www.vintage-computer.com_ (http://www.vintage-computer.com) and do a search on that topic.

House cleaning!

by derschjo＠mail.msu.edu

So I've amassed way too much stuff lately and I have a lot of cool stuff that I never touch anymore, so I'm thinning out my collection a bit to free up some space. Smallish stuff I'll ship, but the large stuff is local pick-up only. (Seattle, WA area). Happy to drive out a ways to meet you if it helps. Make an offer -- no reasonable offer refused. Stuff that doesn't get claimed 'll probably end up on eBay eventually. Thanks! Josh Monitors: --------- - Amdek Color II - Works. - Gateway 2000, 15" Vivitron (does 1280x1024, actually a nice SVGA...) - Ball 9" CRT Terminals: ---------- - Intertec InterTube II - Does not work. Makes horrible hissing/screeching on power-up. Dirty, but will clean up. - Beehive SuperBee - No keyboard. Needs work. Ugly looking on the outside, but very clean inside, given how old it is. - Wang terminal - Cannot find model on case, believe it to be part of an old Wang word-processing system. Built like a tank. Computers: ---------- - Compaq Portable III - Worked the last time I powered it up. Hard drive, 5.25" floppy drive. - Compaq Portable 386 - Also works. 2MB ram, hard drive. Carrying case (travel in style!) - Dell Optiplex, Dual PPro/w P2-Overdrive. No HD, I have RAM somewhere. - HP 9000/236 - W/Monitor. Works, but floppy controller reports errors on startup. - HP 9826 - Was working, but monitor no longer powers up. - Mac Plus - Not working. - Pet 2001 (32k) - Works - CBM 8032 - Works, PCB is a bit hacked up, but works. - ComputerVision CADDStation 32 - Neat old Sun3-based machine I inherited awhile back. Really heavy, no I will not ship. Just the machine, none of the various CAD-related input devices. Mostly working -- CPU board needs repair (but it's just a rebadged Sun3 VME processor board so it's not impossible to find parts...) SGI Personal Iris 4D/35 + Iris File. No RAM, alas. Chassis has a bit of rust, but is otherwise solid. TRS-80 Model II + external 8" drive box (w/2 drives installed). Works, a bit worn. (Have not tested all the drives.) Laptops: -------- A goodish stack of older laptops. 386, 486, and Pentium. Ask for details. Take one, take all... take as many as you want! Misc: ----- CBM 2031 5.25" floppy drive - works CBM 4040 dual 5.25" drive - does not work. DECServer 200/MC. Appears to work. Never took the time to set up a machine with LAT, etc... to try it out. HP 1200B Oscilloscope. Rack mountable, Dual trace. Needs some repair (trace does not scan across the screen correctly.)

Simulation vs breadboarding (was Replacing failed powersupplies on qbus PDP-11s)

KEEP annoucement

by aek＠bitsavers.org

From another mailing list: > I am glad to announce, that a major European research project, which is related to the preservation of complex digital artefacts, has just started. KEEP (Keeping Emulation Environments Portable) is funded by the European Community with 3,15 Mio. Euro will go on from now for three years. Aim of the project is to utilize the preservation tools, which are mainly created in the gamer community, for a broader range of users and purposes. The impact of the project lies also in the structure of the consortium itself: for the first time traditional memory institutions like the national libraries of France, Germany and Netherlands and researchers with a background in humanitities (University of Portsmouth) come together with organisations specialized in games resp. their preservation (Computer Game Museum, European Games Developer Federation ) within a common research effort in such a scale. I am pretty sure, that we will be able to boost the awareness of the need to preserve the gaming culture on that basis and of course provide concrete preservation tools and interfaces to do the job. > > More details about the project can be found here: > http://www.computerspielemuseum.de/index.php?lg=en&main=News&site=02:00:00&…

8048 Intel programming languages

How about this: Did they ever >release any sort of languages for the IMSAI 8048 board? You have an Imp48???? First if you have a manual I'd appreciate a copy, I've been looking for 28 years for one! Yes, I have one too, I know the general circuit for mine by reverse engineering it and I do use it for playing. As to languages for 8048, IMSAI never did. The concept of a higher level language for a board with 1K of program space is only a thing you hear lately. One reason is the limited stack and ram/romspace of the 8048 really does require the efficientcy of assembler. It's possile to create some varient of a tiny micro basic but then it has to fit in 1K and also any program in the same 1k. If you working with 8048/9 off that board more space is possible but remember the ability to address ram without some banking scheme is limited to 256 bytes. I'd say keep looking though as I've likely missed a few. I'm sure it's possible to tweak the code generator in SDCC to do 8048 and it's rare anyone uses more than 4k. But the compiler logic to do the bank switch is likely insane since interrupts are only handled in the low memory page. There are all sorts of cross assemblers out there.

Yes, I know all about those drives, and I have one that it is "semi-operational". I worked on these in 1979 and had them connected to a 6800 system. While they worked most of the time, they were a bit picky. They needed 36 volt power supplies as well as others. The controller provided actually did work. The early drives had a secondary board that eventually was replaced with an LSI chip. Their main problem was that they were a bit (well actually more than that) temperamental. The drives themselves were only 10Mbyte goodies, and used embedded servos with on-track sparing. The disks themselves were "cut-down" from 14 inch media (like 2315's). Thankfully I eventually replaced these with SMD drives, then 5 1/4 drives with the Xebec 1410 controller (SASI). All on a 6800! Fun in the early 80's

Anyone have a line on batteries for the NLS

For the NLS 'scopes the battery is between the charge source and the scope power supply so if it's open (badly sulfated as the battery is lead acid gell type) the PS has to carry the load. It's only a charger. if you substitute a larger charger then you find the charge circuit does not have the capacity to start the unit (initial surge current). >Assuming the battery pack is just a battery (that is, no 'battery >management' circuitry), you can often run the unit from a bench power >supply connected to the battery wires _with the battery disconnected_. Of >course this assuems you have a suitable PSU... The pack in this case is just 3 2v cells and the "management" is the charge circuit on the rear board. In this case (nls miniscopes) a 6V PS can substitute for the battery at less tha 1A (must be connected to the ground and +6V termianls of the battery connection point internally). Only if the battery is removed first. Note that is the battery has failed (usually sulfated from not being kept charged) they tend to build corrosion around the terminal, they are best removed and recycled as any gelled lead acid battery should be. Since I use my miniscopes intermittently I've long since removed the battery and disconnected the internal charge circuit (pull the fuse). The battery area has a small board inserted to allow it to accept any voltage from 9 to 30V and run from that. Since I have a number of small 12V gell cells that fit nicely in the probe pocket of the carry case this proves more useful and maintainable. The change is completely reverseable and the ability to use a larger and longer lasting 12V battery as source is very handy. The NLS is somewhat unique as it uses a lead acid type rather than NiCd, Nimh, lithium or even common dry cells. In an emergency I have run it off 4 'D" sized alkaline cells in an external holder for many hours. Allison

What do you mean by "NPR cards"? Technically there is no such thing. There is the bus grant cards, and the extended bus grant cards which also carry the NPR signal. The normal bus grant cards only carry BG signals, and thus you normally need to connect/disconnect the NPR wire on the backplane. The symptoms you describe sounds pretty much like an NPR signal problem, but of course, it could be a number of different things. > 2. I have a Plessy PM1116/B core card.

Gates was a major provider of the single 2V cell in the "D" size with tabs on one end. NLS used three of them but a 6V monolythic battery with the same outer dimensions will also work fine as the tabs soldered to the rear board for mounting and to create a series connection.

Mr. Fox, I just discovered your message on the Internet. What do you want to know about it. I still have an SMC 70 and SMC 70G, manuals, and accessories in the garage. I purchased my first one about 1984. They were so far ahead of their times. They were even Y2K compatible. The only one that was when the Y2K panic hit. Cheers, James
