I must be a dolt, but I can't seem to figure out how to open up my IBM 5155 Portable. How do I crack this thing open without damaging something? I want to add some cards to it (including a hard drive which is going to be tricky since it doesn't look like there's a lot of room in there) -- Jim Leonard (trixter at oldskool.org) http://www.oldskool.org/ Help our electronic games project: http://www.mobygames.com/ Or check out some trippy MindCandy at http://www.mindcandydvd.com/ A child borne of the home computer wars: http://trixter.wordpress.com/

The AGS's description of >Syl-Glyde made me think it's actually not silicone. > >Chad Fernandez >Michigan, USA Hi My understanding is that it is silicone grease. It seem to be the same as the silicone grease that NAPA stores sell under their brand name. Many dielectric greases are not silicon based but may work as well to improve contacts of connectors. I've gotten good results from Syl-Glyde, even on connectors that have been weakened by over heating ( common in pinball machines ). I still prefer to use DC#4 but I often can't find the tube and use what is in the tool box. Dwight

Sorting large box of 72 pin SIMMs - looking for chip ID guide

by ethan.dicks＠gmail.com

Hi, I have a largish box of random 72-pin memory, but I can't seem to find a guide online that will help me differentiate the types of memory based on the manufacturer's chip numbers. I recall back in the day, one could look at the last couple of digits of the memory chip part number to tell FPM from EDO, etc. Unfortunately, two evenings of googlings has only found me consumer-level guides to help clueless PC owners tell SIMMs from DIMMs - nothing at the chip level. Thanks for any pointers, -ethan

another mysterious chip

by chrism3667＠yahoo.com

First line: circle possibly with M in it, INMOS B. Second line: IMSG170S35 (pretty sure). Third line: 8611 - obviously date of manufacture. Chip has a gold cover, and is present on a dual 8-bit graphics card made by Vermont Microsystems, 80188 on board (similar to an IBM PGA card). Works in a P166MMX DTK mobo...but not in my IBM PC/AT. And yer know what else...it emulates CGA (pretty well seemingly, but only tested it with QBasic thus far). O for the drivers to access its wild advanced modes *snifful*. __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!

Redux on sound-deadening foam

by cclist＠sydex.com

Just went through another printer with 1/4" of black sound-deadening foam attached to the insides of the enclosure in absolutely terrible shape. I found that warm soapy water is the easiest way to remove it--it just disintegrates into sludge when the water hits it. I'm thinking of replacing it with 1/2" styrofoam. The noise to be attenuated is high-frequency 1-3KHz from the printhead. Does anyone have any thoughts on this--leaving any sound absorption off is a little more than my ears can take. Thanks, Chuck

Thunderscan

by kenziem＠sympatico.ca

Just picked up an interesting piece of hardware. It's a Thunderscan, The working end replaces the ribbon cartridge in an Imagewriter, The page to be scanned is fed in to the printer and the optical sensor then scans the page. It came with a 512 Mac with the demo tape, and reset clip, and floppies still in the box. It powers up OK, but after a while goes blank, a tap to the side restores the screen. Has anyone else seen a thunderscan? -- Open Source Weekend http://www.osw.ca
