Archiving Apple II disksby billdeg Total messages in this thread: 2 Updated: [ Apple IIGS 3.6v MB Battery ] 11/28/2008 Test subject: Apple II GS with 3.5 and 5 1/4" drives, ADT 1.21 and a bunch of diskettes. 
Apple II GS Computer running ADT 1.21 I decided it was time to learn how to archive Apple II disks by copying them (somehow) to a modern computer. I chose an Apple II GS as the bridge system because it has a 3.5 and 5 1/4" disk drive, and it can read old Apple II diskettes. The question is how to take make disk images and save them to 3.5 disk, and then find a modern system to read the 3.5 disks. Finally I will need to be able to both run the disk images in an Apple II emulator, and also move disk images from other sources to the Apple II GS for extraction onto 5 1/4" in Apple DOS 3.3 format for use on an Apple II (II-->IIe).

TM 990/189 or PP189by njoerd_de Total messages in this thread: 3 Updated: [ re:TM 990/189 or PP189 ] 10/21/2008 Hello to all, I get a TM 990/189 System from one of my friends. The interesting point is that the system is build in a black box. You can detach the cover from it. On the cove there are the letters PP189 and of course the Texas Instruments brand name. I searched in the internet to get more information about this system. I found some of the PCB (TM 990/189) itself but nothing about the box. Do anyone know more about it?

Removing yellowing from plasticsby billdeg Total messages in this thread: 1 This is a reprint from http://www.vintage-computer.com/vcforum, but I thought it worth mirroring here. To follow is an excellent synopsis on the subject, taken from a 200 record thread: - Part 2 (by "Merlin") "...The original thread is over 200 posts long now and getting to be a heavy read for some, so Lorne and I thought it was best that we start a new thread here, with a "Story So Far" summary, before we start more experiments. So, what has been discovered and learned so far? 1. We have learned that a magic concoction has been created that can reverse the years of yellowing of plastics, caused by the brominated flame retardants (which were added to the plastic when it was a masterbatch) migrating to the surface of the plastic and attracting oxygen molecules which become attached by a co-ordinate bond. 2. Bromine molecules are susceptible to ultra-violet light, in that che">... [ read more ] |
