[possibly OT]: Tektronix 466 - spares needed

by philpem＠dsl.pipex.com

Hi, A few days ago I picked up a very nice Tektronix 466 storage oscilloscope, complete with service manual. Catch is, I don't have the operator's manual. The service manual is thick with schematics and parts manifests, a fair bit of technical info ("this part does x function", etc). No real information on how to actually *use* this thing. I've worked out what 90% of the controls do by trial and error (that, plus the fact I used another scope before this one), but the storage section and some of the trigger section still eludes me... Scanned images or photocopy prefered, original manual would be even better. Also, it seems to be missing the blue cover that goes over the front panel and a set of Tek 1x/10x probes that were supposed to come with it. Anyone got a 466 as a junker they wouldn't mind parting out? I've been told Tek abandoned this scope a long time ago... Thanks. -- Phil. philpem(a)dsl.pipex.com http://www.philpem.dsl.pipex.com/

Bootstrapping a CP/M system to usability :)

by archer＠topnow.com

I'm suffering from what one might call the "first program" problem. That is, I want to download CP/M programs (editor, assembler, and BASICK for starters) from the 'net and transfer them from my PC to my "CP/M" machine (A Commie 128 running CP/M+) to save on floppy for later use. I can boot CP/M+ on Commie, but the distribution is very minimal. It doesn't even include ED. It does have PIP, if this is useful, but no MAC, BASIC, or any other goodies that might be used to pull in xmodem or some other file transfer program into the machine and thus create a mechanism for transferring binary files into the machine from the PC. This must be a common problem, but surprisingly a web search yielded little insight on how to get the "first file" in. My extreme ignorance of CP/M at this point in time is not helpful either. With Apples, I know there was a trick to basically feed a BASIC program in from the serial port as if it were entered by the keyboard. With Commie-doors, there's the XE1541 cable and software to do the trick (but I don't think it can write MFM as needed by C128 CP/M mode.) Is there any similar "tricks" for CP/M? Without an assembler I would need to get a binary file into the CP/M floppy somehow. I don't have a 5 1/4" floppy drive in any PC but would consider scouring the Junque places for one if that could write files on my PC readable on CP/M. Or maybe I'm missing something and it's all so simple that nobody bothers to document it? Thanks for any clues. I want to be conversant with CP/M. Something to put on my resume. ;) -- Ross which is surely very common but oddly websearches have yielded no real insight as to how to fix it.

update: Commodore stuff for goodbye... (and one OT item...)

by zmerch＠30below.com

=-=-= Most of the commodore stuff has been claimed, but the claimant wasn't "as interested" in the following items; so they're still available (for a short time, this stuff's gotta go...) : =-=-= Shipping from 49783; have a "Pack -n- ship" place next door, so there is usually a surcharge to normal UPS/Fedex prices (being next door, we usually get a bit of a break, however). All of these items are "condition unknown" - they were given to me, and I've never had 'em hooked up. No warranties, and all that jazz. (1) MPS802 printer - in original box with original styrofoam; ready to ship (just needs to be taped up) - looks to be in really good shape, but that's just looks... (1) MPS802 printer - no box, no top cover. The stuff's gotta go ASAP, so unforch, it's first come, first served... =-=-=-=-=-=-=-=-=-=-=-=-=-= OT blurb: I have a PlayStation 1 available with some interesting goodies; $100 shipped; contact me off-list if interested. -- Roger "Merch" Merchberger --- sysadmin, Iceberg Computers Recycling is good, right??? Ok, so I'll recycle an old .sig. If at first you don't succeed, nuclear warhead disarmament should *not* be your first career choice.

I've just finished putting a bunch of stuff on E-bay that may interest this group. (I know, I know, but I have to try and keep this hobby self-supporting). Items include a Sharp PC-7000 Portable computer, some DRI C language manuals, a couple of HP 9815 interfaces, a RAID controller for IDE drives, a SUN type 5 mechanical mouse, a National Instruments VME GP-IB interface and lots of other odds and ends.

(PUN: perhaps?) > ---snip--- Hi I find it easier to white a simple serial to memory routine and then use SAVE to create the image files. One doesn't have to worry about handshake since the program can run at full speed. Since this is a true image, one can transfer .HEX or .COM files without dealing with LOAD that is not built into the command processor. Dwight

VAX 4000 200 console bulkhead wanted

by rschaefe＠gcfn.org

I just moved my '200 boardset into what used to be a BA440 expansion chassis, and now I need to replace the MVII-style console bulkhead. If anyone has one they'd be willing to get rid of/trade for, let me know. Thanks! Bob
