This one is probably a long shot, but wondering if anyone has any documentation for a Mohawk Data Sciences model 2166 paper tape reader. The unit I have is s/n 2047 and was built by Mohawk, Montvale NJ probably in the early to mid 70's. It's an all mechanical reader with 24VDC solonoid and ratchet that advances the tape. It came out of a Control Data maintanance console for the Star-100, which sadly, as a kid, I parted out. All I have left is the cool aluminum suitcase that it was built in... and this paper tape reader. Chris -- Chris Elmquist mailto:chrise at pobox.com

It depends on the material of the drum, the RPM of the drum, depth of cut, and how sharp your cutter is. Lapping probably wouldn't hurt, but you don't want to be trying to take out gouges and scratches just by lapping. -Bobby

VAXwheels

by wdonzelli＠gmail.com

Can someone with either a VAX 11/780 or, more preferably, a VAX 11/785, tell me what is involved with the wheels or casters? This Thursday we are getting a VAX 11/785, and we just found out it has no wheels. I have some caster sets that maybe I can bolt on, but I need to know what bolts to use, and if there are any issues (clearance above or below the chassis, for example). This VAX has apparently spent the last ten years of life doing nothing more than an RX01 controller, writing floppies. -- Will

WANTED: someone to transfer IBM 5110 BASIC programs

by tosteve＠yahoo.com

Apparently, there are *150* diskettes to be read... It may be easier to send the computer to him... ....except that it weighs over 100 pounds. --- On Mon, 12/1/08, steven stengel <tosteve at yahoo.com> wrote: > From: steven stengel <tosteve at yahoo.com> > Subject: WANTED: someone to transfer IBM 5110 BASIC programs to modern PC > To: cctech at classiccmp.org > Date: Monday, December 1, 2008, 11:16 AM > Hello, > A gentleman from the East Coast contacted me to see if I > can extract old BASIC programs from his IBM-5110 8-inch > floppy disks. > > I have a working IBM-5120 with internal floppy drives, but > the serial communications option is not installed in my > system. > > I think the best I can do is LIST the programs and > photograph the screen. > > Any other ideas? > Anyone else with a serial port who can do it? > Anyone with a spare communications card? > > Thanks- > Steven Stengel

Hi, I've got an RRD42 CDROM drive that requires a caddy to put the CDROM. Does anyone in the UK have one of these they could spare? Many thanks for the help, Mark.

Open source, stand alone, ASCII terminal project

> > Enough firmware finished now to be a functional VT220 clone > > Including vomit-inducing smooth scroll? :-) Yes, indeed. It turns out that this only took a remarkably small amount of code. I've always thought that smooth scrolling was pretty cool, but never wanted to actually use it. James Markevitch

Plenty of forums, web sites, etc. for the coin-op collecting scene as well. Google is your friend. ;) And as a happy visitor to the last two, I'll also say that this show has had a great side-show of classic-era consumer computers and rare peripherals, too. - John
