Calling all hoarders! I have been trying to get my old Fido BBS (circa 1983) running again on my DEC Rainbow. The original Tom Jennings code got trashed in a system crash may years ago. There's bits of it on his BBS but I would need to be a much better C programmer to have a hope of fixing it. There are copies on the old Decus site but the un-squeezer's (NUSQ & NUSQ110) just report errors. I know about FOSSIL but its FIDO_DEC.exe I'm really after. Does anybody have or know where FIDO_DEC.exe might be found. Rod Smallwood

Wire-OR is fine until you need to find out which signal is driving the input low, or should I say to logic '1' (my machine uses -6.3v = logic 1, 0v = logic 0). You need to isolate all the outputs to check them, not TOO hard on a wire wrapped machine but must be a swine if you've soldered everything together. Of course there still the other problem, if you need two or more wire-ORs from the same output, you need to buffer the outputs separately or generate the signal two or more times.

old simtel contents

by dgriffi＠cs.csubak.edu

Does anyone still mirror the old Simtel archives anymore? I'm in need of msdos/arcers/extar10.zip among other things. -- David Griffith dgriffi at cs.csubak.edu A: Because it fouls the order in which people normally read text.

Apple II Europlus keyboard

by laurens＠daemon.be

Hello everyone, After a long time, I've booted my Apple II again. However, it seems that some keys on the keyboard are not always working. I can get some to work by pressing quickly & hard a couple of times. Before I'm going to pry open the keyboard, is it "normal" that these keys don't seem to make contact? Also, I forgot the name of the recently discovered old case cleaner material, does anyone know this? Thanks in advance!

Cleaning packs

by wdonzelli＠gmail.com

> On the other hand, it isn't impossible to find used red packs. > CLEAN packs may be more difficult, though. One thing that I fear is that the knowledge to *properly* clean a pack is going away. There is (was?) a place near Boston that would do it, and I am sure Farris can as well, but I know of no others. It would be nice to document how packs are cleaned, so we can do this in the future. Speaking of Farris - is someone keeping an eye on them? Some day they are going to call it quits, and they have quite the pile to be saved. -- Will

Straight-8 cabinet

by wdonzelli＠gmail.com

Well, now that it looks like the Dallas mystery cabinet is ID'd as possibly for a PDP-7, this started me thinking. Kicking around here is what I think it one of the extruded aluminum handles for a Straight-8 - one of the long ones that goes up the front door. It is (I think) the right shape, right length, and has decals MA thru MF inside. Does anyone need this for a restoration? Give me a sob story and shipping money and you can have it. -- Will

DEC CR10 card reader info?

by hachti＠hachti.de

Hi, does anyone have information (docs) on the DEC CR10 card reader? It has a Soroban "Desk Top Card Reader", type "ERD" inside. I could rescue that machine. But it's not that small. So I would like to know if anybody thinks I could use this with another computer than a PDP10 (without using too much modern interfacing). If anybody else is interested in the machine, let me know. It's located in northern Germany. Best wishes, Philipp -- http://www.hachti.de
