I have acquired a KSR 43 and am looking for a manual. I've looked in the usual online archives (and printed-manual resellers too) Can anyone help? Also I'm looking for a tape punch and the complete top cover assembly for an ASR 33. thanks Charles

The mid chip Vcc and ground went all the way back to the Moto and Fairchild RTL (in dip) or opposing pins in the 8/10/12 leaded TO5 (can) varient. However when it came to part numbers Moto is infamous for a plethora of "house numbers" where the number is not EIA or ISO or anthing else and was special for a project or customer. Most of the other vendors did that as well but Motorola was wild. HeathKit was a common consumer of house numberd parts from many vendors. Allison

Found the system model! Was Re: Need BIOS setup utility

by marvin＠rain.org

Hmmm, I thought that the need for an external utility to set up the CMOS went away with the 286. IIRC, Cntl/Alt/Ins was used on the/some Phoenix BIOS chipset(s) to gain access to the CMOS setup routines. There were several other such keystroke sequences but the only other one that comes to mind was Cntl/Alt/S. Also, I *think* that the IBM Diagnostics will also work and might be enough to take away the boot error (excepting that it doesn't support the 47 HD types used in most of the later BIOSs.) charset=ISO-8859-1; format=flowed > > It's a Vobis LCD-386: > > http://www.hknebel.org/Museum/Museum/Tragbare_PCs/Nicht_IBM_PCs/Vobis_LCD38… > > There was one on eBay early this month, too.

Apple 1 on eBay - shameless self promotion

by curt＠atarimuseum.com

Bryan, Nice work, does your board clearly state in layer traces or in silkscreen (Apple-1 Recreation) so that as years go by, if the system is passed onto to new owners, they don't mistake yours for an actual original? I'm all for have near exact stuff done, so long as any product clearly states on it that its not an original so as not to create confusion. May I ask, what kind of keyboard are you using???

open source crap was Re: Archiving Software

I write a lot of code. None for the most part appears in the public realm. There are several reasons for this. One being my favorite language is solder. Others include must of the code is crap, one off and quickies while useful are not worth much. HOWEVER... Once I went to great lenghts to put out a subsection of CP/M bios using 765 for general interest and no particular use. The result, one moaned about the assembler used (plain ASM), another was disappointed I didn't use Z80 instructions and Opcodes, A two tried to tell me it can't work (it was from the system that used/assembled it!). My response was and is still FREE IMPLIES: YOU GET WHAT YOU PAY FOR. Caps inteneded.. Often rather than getting mad accept it for what it is. Allison

If you can ethernet you can rcp the files. I've done that with bsd on a vax. Basically I mount a big partitionon the disk, rcp the file overand then untar it. I suspect you don't have a qbus ethernet card. Is that the case? ---------------- I do not have an QBus ethernet card, just a Unibus one. I doubt I can access RCP as it's probably not part of the root install. But I could be wrong. Why would it matter if I had a Qbus Ethernet card or not? _______________________________________________ Join Excite! - http://www.excite.com The most personalized portal on the Web!

TO cross most I use a NTE or other parts sub manaul to find out what it is then work backward to a usuable number. tedious but near the only way to get from a M9313 RF transistor to a 2N or MRFxxxx part number.

I have the "Damn Fast" datasheets, and at least one databook which includes them. I have some of the parts too -- I once built a scope probe out of them. I think it was one of the application notes. -- Pete Peter Turnbull Network Manager University of York
