This looks like a huge typewriter with dual 5 1/4" floppies under the keyboard and a 9" or so (mono?) CRT on a pivot above the platen area. It turns on and responds to keypresses. The only thing I can get the CRT to show is "Insert INST Disk" when I press some of the buttons above the keyboard. Since I don't have any disks or docs, there's not much more I can figure out. If anyone would like this beast, it's in Lincoln NE.

Circuit Cellar TI-74 article

That's the second place I looked. I checked out Dave Tweed's on-line archive first. However "free" is indeed cheaper than $29 for the CD or $5 for the individual issue, from which I only want that article. If no one has it, that I will break-down and purchase the CD. -----Original Message----- From: cctalk-bounces at classiccmp.org [mailto:cctalk-bounces at classiccmp.org] On Behalf Of Frank McConnell Sent: Thursday, September 15, 2005 1:02 AM To: cctalk at classiccmp.org Subject: Re: Circuit Cellar TI-74 article Richard Cini wrote: > Does anyone have a copy of the April/May 1991 issue (Issue #20) of Circuit > Cellar and can scan an article for me?

Suggestions for a mini?

by tomj＠wps.com

I'd like to solicit suggestions for a mini... I have this Nova 4, http://wps.com/NOVA4, but it's taking up too much space, physical and psychic. I do want a mini-era machine, and after some thought, I worked out what I'd like to get from one. What I want is a basic stripped machine, with CRT console and high-speed paper tape reader, and a low-speed punch (this last is variable), and standlone utilities. It must have a front panel. I've used such on two platforms (Varian 622/i, Nova 1200) and it's precisely the sort of (relatively) low-maintenance, high-geek vintage experience I want. So I'd like to trade my kilopound of DG gear, documentation, tapes, fiche, etc for about 100 lbs of minicomputer. I'd prefer a DG Nova, General Automation, Varian, or other non-DEC brand. (No offense to DECcies, I have a strong preference for off the beaten path.) Even or especially one-off oddball or unpopular, or slow, or ugly machines. Off models, step-cousin machines etc. Poorly optioned (eg. math or fancy interfaces). Something like (but of course unlikely to be sucha popular model): Nova 1200 16 or 32k words tty port ptp/ptr port lpt port or equiv I have generic high-speed paper tape readers, serial interface. I don't care if peripheral brands match. It would be nice to have reel tape support. Any suggestions on interesting and obtainable machines?

Circuit Cellar TI-74 article

All: Does anyone have a copy of the April/May 1991 issue (Issue #20) of Circuit Cellar and can scan an article for me? There's an article on using the TI-74 BASICCALC for data acquisition and control. The article, written by Ed Vogel, appears beginning on page 41. TIA. Rich

OT: Older Color Laser Printer Repair or replacement.

by zmerch＠30below.com

=-=-=-= Of course: replies offlist, please!!! =-=-=-= Anyone here know boatloads about older color laser printers? Well, it's almost ontopic - the printer's 7 or 8 years old, IIRC, and it's got plusses for 'kewl-factor'. ;-) Well, it *used* to... see below. I have a QMS MagiColor 2 (CX engine) with lots of extra goodies: 112Meg RAM, 2G SCSI hard drive, *serial port*, Ethernut... and the thing just started going to Hades in a handbasket. It's always been a little flaky with paper handling, but otherwise has been ultra-reliable if you knew it's paper quirks. Now it's durned near impossible to deal with... but that's not the *big* problem. The nearly new black toner cart (less than 1000 sheets of it's 10000 sheet life) is now 'low', the nearly new magenta toner cart ( less than 500 sheets) is *out*, and I had to hack up a cyan cart with the magenta 'code insert thingy' to fool it into printing again (if any toner goes 'emtpy' the printer refuses to print) and the nearly new OPC belt ( less than 2000 of a 30000+ page lifespan) has developed several bad spots. All this seemed to happen within 100 pages or so. :-O Is the printer worth saving, or should I just drop it off my deck (10 foot drop - would be quite satisfying to see, after I strip the HD and memory out of it...)? Or does anyone want it for parts for cost of shipping? (Warning: it's a 110+ pound beastie; it would *not* be cheap to ship.) If it's not worth saving, anyone have experience with a good color laser printer? Preferably < $1000, and I want *bitchin* paper handling (read: no paper jams). Please don't say HP. ;-) The best I've found during my research so far is the Ricoh Aficio CL2000N - about $560 street price, and has oodles of options available (most of which I don't need), affordable consumables, and supposedly really good paper handling, according to the reviews I've found. Oh, and about 1/2 the weight of my current printer. Sorry for the offtopicness, but I don't know where else to turn, and I'm looking for advice from people I trust. ;-) Thanks, Roger "Merch" Merchberger -- Roger "Merch" Merchberger -- SysAdmin, Iceberg Computers zmerch at 30below.com Hi!

Homebrew Circuit Boards: Methods? Supplies?

by Steven_R_Hutchins＠Raytheon.com

DIY is fun, but try this site for pc boards. $88. for quantity 2, double sided boards, 4 day turnaround $122 for quantity 2, 4 layer boards, 4 day turnaround Same price up to 85 sq. inches. High quality boards. Just make sure you follow the rules for the "No touch" price, because they send you exactly what your Gerbers contain. |---------+-----------------------------> | | Roger Merchberger | | | <zmerch at 30below.co| | | m> | | | Sent by: | | | cctech-bounces at cla| | | ssiccmp.org | | | | | | | | | 09/07/2005 12:58 | | | PM | | | Please respond to | | | "General | | | Discussion: | | | On-Topic Posts | | | Only" | | | | |---------+-----------------------------> >---------------------------------------------------------------------------------------------------------------| | | | To: "General Discussion: On-Topic and Off-Topic Posts" <cctalk at classiccmp.org> | | cc: | | Subject: Re: Homebrew Circuit Boards: Methods?

I got my stuff at http://www.circuitspecialists.com/ Best prices & selection I could find and they have 1/16", 1/32" and 1/64" thickness pre-sensitized photoresist boards. They even have "how-to" books for beginners on making photoresist boards & whatnot. http://www.circuitspecialists.com/prod.itml/icOid/7783 (Link to the beginners book I mentioned - I bought it and it's a very good read.) I have not yet had time to build the projects for which I purchased my shiznit, but I should be able to before Xmas, so I'll know a lot more soon... ;-) I am not affiliated with the company other than being a (so far) satisfied customer. >In fact, I have not been able to find precoated board (photoresist coated) >in the .050" thickness. So I will either need to use a liquid photoresist >or try a toner transfer system. I dunno about 0.050", but would the 1/32" thickness be close enough? (That's 0.03125" thickness, if you can believe the Winders calcaputer applet ;-) >That raises other questions. Are the Toner Transfer Systems reliable No. Especially since the toner xfer systems were designed around toner that melts around 300 deg. C... a lot of the 'microfine' toner printers melt their toner a *lot* hotter than that, and don't get good adhesion to the xfer sheets. (Most laser printers made in the last 5-8 years are all microfine toner - anything 600dpi+ will be.) The last time I tried (5+ years ago) I used 10 sheets to *finally* get one that didn't require metric buttloads of touchups with a resist pen. >If the TTS is not servicable, then I'll try the liquid photoresist. I'd say to try pre-sensitized... but that's just me. > Would it be better to simply spray on, or should I try to rig a spinner? > >Do the developer and/or stripper usually turn out to be some commonly >(cheaply) available chemical? I would prefer to avoid paying $6+ for a >small bottle if I can avoid it. One kg of ammonium persulfate will make 4 liters of etchant, and it's around $18 USD (not including shipping) - not sure if you'll be able to find it much cheaper than that, but if you do, let everyone here know! ;-) The other chemical used is ferric chloride.
