Saw your msg below while searching the Web about Persci drives. I have a 277 manual, courtesty of Cromemco, in my inventory. I normally sell copies by the page but I would trade for copies of some of your manuals. Confirm you are still interested and we can work the details. I have the Persci 277, 299, (8-inch) manuals; what is the 207 and 272? Herb Johnson Your msg, late in 2003: My newly-acquired Cromemco System 3 came with lots of disks, spare boards, manuals, licences, and a terminal, but only one dual PerSci S299 floppy drive, which needs some attention (it seeks but returns read errors). Anyone got a manual I can download, borrow or trade? I have two sets of manuals (2 of each of the "Product Specification" and "Logic and Schematic Diagram") for the 270/272/277 drives, several spare ADM-5 manuals, and some spare Cromemco FDC manuals. -- Pete Peter Turnbull Network Manager University of York -- Herbert R.

cctalk Digest, Vol 6, Issue 29

I would stay away from the Tek 2400 series if at all possible. That generation of Tek 'scopes use custom Integrated circuits that are no longer produced and are virtually unobtainable. There are a dearth of replacement parts. You'll find you have to canibalize other 2400 series 'scopes to keep yours going. Particulary I would avoid any 2400 series scope that has problems. Unless you need parts out of it, of course. Or, of course, if you're a Tek Scope collector. I am old fashioned and wouldn't part with my Tek 465. The 7000 series mainframe 'scopes are incredibly inexpensive on the used market these days as well. I have one I may list on eBay soon.

Odd question about microwaves and magnetic media

by Lee.Davison＠merlincommunications.com

> Can magnetic media setting in proximity to a microwave be affected by the > microwaves or anything else in the oven (the magnetron for instance)? Not unless the microwave is in some way defective, if it does then it's more a hazzard to you than the magnetic media. > so I've put the microwave oven for heating my burritos on the same table > where I'm setting up my data conversion station. > I guess it probably isn't be a good idea. Probably not, food near IT equipment is never a good idea. > Ok, another experiment: place a floppy disk with data on a large monitor it would be quicker on a small monitor, the degauss field tends to be stronger as the coil is smaller for about the same current, but ... > and hit the degauss button, then check to see what is left on the disk Whatever was on it before for HD disks and usually the same for DD. The inverse square law for the field means you need linear motor strength fields before you can approach the field strength found under the head and reliably erase data.

Hi Does the tupperware work for un-cracked eggs as well or do they just blow the lid off?
