recovering cartridge tapes (was: Tek fiches found!

by tshoppa＠wmata.com

> Still the question remains: how best to read cartridge tapes with > faulty belts and sticky drive capstans? Even 20 years ago, it was de rigueur to disassemble the cartridge and replace worn or stretched or deformed rubber parts with new or at least better components from a "donor cartridge". When the decay had left little rubber fragments in the path you had to take the cart apart to remove/clean them before reading anyway. Twenty years ago, only the worst (due to extreme ozone exposure or physical wear) carts needed this. Today the issue is that all the donor cartridges may be 20 or 30 years old too. Tim.

Fanfold paper tape storage bins/trays

by RichA＠vulcan.com

Serious question: We have a number of paper tapes which have been stored in paper boxes for quite some time. I would like, if at all possible, to move these into the kind of storage containers in which many of our tapes already live. These are transparent stable plastic with a lid, divided into 8 sections of Just the Right Size(TM) to hold fanfold paper tape. There is probably no one who makes these any longer, but on the off chance that I am wrong about that, does anyone know (a) who might make these, or (b) what they are called, so that I can try to find them using one of the large search engines, or (c) have a supply of them stashed with which the current owner is willing to part?

Fw: MacPaint and QuickDraw source code released

by richard.cini＠wellsfargo.com

If it was developed on the Lisa, would they have used LisaPascal? There's a Lisa emulator out there -- I might play with it this weekend and see if it works. ------Original Message------ From: Cameron Kaiser Sender: cctalk-bounces at classiccmp.org To: CCTalk ReplyTo: CCTalk Subject: Re: MacPaint and QuickDraw source code released Sent: Jul 22, 2010 11:02 AM > I've never used Think Pascal, but I did use Think C (LightSpeed C) a > lot.

The .rsrc file also needs to be turned into a proper resource fork. My instinct would be to try to pre-process it. I agree THINK Pascal would be the logical, closest first target. -- ------------------------------------ personal: http://www.cameronkaiser.com/ -- Cameron Kaiser * Floodgap Systems * www.floodgap.com * ckaiser at floodgap.com -- The moon may be smaller than the Earth, but it's farther away. ------------- Rich ----------------------------- Richard A.

Looking for PDP8/A RL01 boot proms.

by jdr_use＠bluewin.ch

I am looking for a set of boot proms that would enable me to boot from the RL01 that is connected to my PDP8/A That is, if such a boot prom actually exists..... And as a side note : why is the 8/A so unloved ? Big RL01 disk, 128k memory, fpp processor, all in one case. Try that with another -8 ! Jos

I'm fairly sure I've used DC300s and they were cassettes full of quarter inch tape with a constant peripheral speed drive band inside so no need for variable speed spool motors. Roger Holmes

Serial interfaces

It takes hundreds of cycles and more to >move a simple message, it's a host-based, not bi-directional design, >and it's only available on somewhat newish kit. What drives me crazy is the lack of debugging of the stack. When it's not working on contemporary Windows kit, there's no way I've found to help understand what's not really working. This morning, I plugged a client's thumb drive into their laptop, and the logical drive seemed to disappear at random. I switch connectors, thinking it's a wonky physical connector, no difference. Just unreliable. Another stunner was that vmWare didn't support native USB on the host. They're accomplishing thousands of other miracles, but can't virtualize USB enough for me to connect a drive to a virtual appliance? (I think this is fixed in last month's major release.) I'm often trying to connect client hard drives to backup machines via USB-to-SATA/IDE adapters, and when the drive won't seem to wake-up or show up, there's no way to debug where it is failing. I suspect some of the opacity is deeper in Windows at the logical Disk Management level, with layers of "Disk 1" numbering, logical drives and partitions and SCSI emulation, a registry that records every drive fingerprint ever connected to it (really), etc. Last week, a client's thumb drives weren't being recognized. I had to reinstall Windows. I think Windows was failing at the very top layer, at the moment where a recognized device was known to be hard drive, but it couldn't show it as a logical drive. And yet so many built-in media-readers for CF/SD cards will show logical drive letters to the OS when there's nothing inserted. My desktop shows four. Why? - John

SLAMMING vintage computer auction ends

by chrism3667＠yahoo.com

made you look: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=120596128607&ssPageName=… Canon CX-1. Not in the greatest condition, but it's the first time I've seen one offered. 6809 based. My Canon AS100 has something in the way of a native debugger also (haven't turned it on in over a year). starting bid was 25$. Ended at about 235$. And I had thought that no one even knew it existed.
