Hi people! I'm looking for two things (one or the other). A Manual for an AERCO Easie-ST Ram upgrade Kit for the Atari 520-ST. OR An upgrade kit to upgrade an Atari ST to 4mb of RAM. I have an Aerco Adapter that isn't working, and I think I need the manual to tech it out, AND to upgrade it to 4mb of RAM. I have a Spectre-128 for it, and I'd love to be able to use this machine as a MacPlus for kicks. But 512k isn't enough RAM to do anything useful. Also.. Looking for a SCSI Adapter for the ST as well. __________________________________ Do you Yahoo!? Yahoo! Small Business $15K Web Design Giveaway http://promotions.yahoo.com/design_giveaway/

It says something like " you are a sucker " over and over. ( just kidding but that what you'd be to buy it for more than $.50 ). Dwight

Bit Rot?

by vcf＠siconic.com

Is there a good description of the various forms of ROM/PROM/EPROM bit rot phenomena on the web somewhere? Or could someone provide a good description? I know in the case of EPROMs the charge will eventually "leak". And with masked ROMs and PROMs the "fuse" can actual re-grow and turn a 0 into a 1. We've discussed it briefly before. More detailed information would be appreciated.

Enigma

The main page site is W1TP TELEGRAPH AND SCIENTIFIC >INSTRUMENT MUSEUMS, and has some pretty interesting stuff on it! > >http://w1tp.com/ > Hi In one of the magazines I saw yesterday at the news stand ( forget the name but it is one of those general science like magazines ). They showed a solid state enigma machine that you can get. It basically was a keyboard, lights and a uP on a PC board. I wonder if one can set the number of wheels and the other features that the fancier machines had? Dwight

Motorola M68HC11EVM?

Anybody know >what the differences are between this board and the M68HC11EVB? > > Joe The main difference between the EVM and the EVB are that the EVB is essentially just a single board computer - you can load code into it and run it, and you can hook up things to the I/O ports via board connectors. The EVM is much more powerful - it includes some in-circuit emulation capability. It has a connector with adapters to fit into the MCU socket for a number of HC11 variants, and allows you to replace the target CPU with the board. The EVM also has a ZIP socket with the ability to program the on-board EEPROM of some HC11 variants. I have the MC68HC11EVM manual, but not in "electric" form - worse case I could unbind it (it's only stapled) and scan it... But that would involve a fair bit of time... so "try real hard" to find another source first - if you don't come up with anything, contact me.

Apple Computer Collecting

by marvin＠rain.org

What in the Apple line of computers, etc. is worth keeping, i.e. hardware, software, documentation, and books? Besides the Apple I, are there any other "holy grail" type of items? I have several Apple printers including the Imagewriter and Imagewriter II. Are these as common as dirt so I don't have to feel bad about getting rid of them, or are they worth putting up on the Vintage Computer Marketplace? I *think* the only Apple IIx I don't have is the orginal Apple II and the "Black" Apple II+, and I would still like to keep one each of the II line. The only Macs I am keeping are the original 128K Macs, and maybe one of the 512K machines.
