I have prepared a new blog with wordpress at https://vintagecomputing.info !!!

Thank you.

As we all know, most of the products today are produced in a cost efficient way.
Because of this, vendors always looking for a chance to produce things cheaper.
But because this happens, also quality goes synchronously down.

This happened to Linksys Router (think about forced cisco cloud account usage, which was changed back in October 2012, but also missing features, low quality and early defects).

Like other vendors, Cisco devices does also have a long list of vulnerabilities:
http://securitytracker.com/archives/advisory/6966.html

Now - on top of the above listed facts - there is another great achievement Cisco reached:

They aquired Scansafe a few years ago, their services are named now "Cisco Cloud Web Security" (it seems also be related with the Linksys Router Configuration issue, see above).
I thought they have a team of agents who edits their web filter entries. So they will be able to achieve a defined level of quality at least.
But I was wrong. Their webfilter service seems to be made only by searching keywords, not monitored by humans. My own website here ( www.z80.eu and also this blog ) is now categorized as "virus site". THIS IS ABSOLUTELY RIDICULOUS. I am offering infos about detecting virus, but I do not spread viruses. Cisco, you failed verifiable 100%.


But do you really expect Quality from Cisco ?

P.S.: This was valid for more than one year. Now it's not more categorized as a malware site, due to my continuously sent requests.

As described in http://www.z80.eu/blog/index.php?entry= ... 319-180000 , I got an Apple IIe Card for my LC aka Color Classic.
But this leads into a chicken and egg problem.
I've read at http://www.vectronicsappleworld.com/app ... #equipment and in the section after it how to go on with these images.

But I am totally unsure how to start.

There is a reference to http://www.vectronicsappleworld.com/bas ... inscii.txt which describes how to get the BINSCII.EXE (has nothing to do with PC EXE files!) running with ProDOS. At this point I asked myself how to get BINSCII.EXE to the ProDOS Partition, which must be the first step after downloading the file.

Also, ShrinkIt and Copy II Plus is mentioned then, I have to get it running after I managed the above BINSCII problem.

Even if I got both running (BINSCII and ShrinkIt), I am unsure about the next step.

After I downloaded a 140KB image file and copy it to the Mac, should I use BINSCII first, then Shrinkit (I do not know how to get this onto my ProDOS formatted partition), and then Copy II Plus to write the image back to a floppy drive ?
So do I have to own a Apple 5.25 Drive, otherwise I'm lost ?
I guess my build-in HD floppy drive will not help (for nothing).


I asked the author, but he didn't answer. Any hints are welcome !

Looking at the wonderful bootscreen of a DEC PWS 433 during BIOS boot phase, I had the idea to preserve this image. Looking around for the image file, I wasn't successful.
So I made a picture with my Nikon and cropped & scaled for Win7 Boot Updater, see
http://www.coderforlife.com/projects/win7boot/
Download the program (no installation required), and choose "complete" for the background picture:

You do not have to choose other options (let the animated windows logo as is).
And here's the background image file itself you have to choose:


Happy DEC PWS booting...

After my short intermezzo with a Mac SE/30, I tried my luck with a Macintosh Colour Classic.
This machine, untruly called the ugly duck of all all-in-one Macs, has a real cute Trinitron color display CRT, and in contrast to a Macintosh Plus or a Macintosh SE, has also a LC PDS slot for some real interesting expansion cards. Btw - it was also the first Mac with a build-in microphone.
You need an external Apple CD-ROM drive for easy MacOS installation also.


At the moment only 8MB of RAM are recognized, but for MacOS 7.5.5, this is enough for work. I am still trying to get 10MB (this is unfortunately already the limit).
For more infos about RAM compatibility, take a look at http://www.jagshouse.com/ram_guide.html

I was also thinking about installing MacOS 7.1.1, but too many convinient features are missing in MacOS 7.1.1, and some programs require at least MacOS 7.5 ...

Meanwhile I got the Apple IIe card also. I am very curious about the results working with this card, which can fully emulate an Apple IIe without any compatibility issues.

To work with a 5.25" floppy drive, I have to solder my own drive cable adapter with a rare 26pin D-SUB connector, but this should be manageable.

For more infos about this card, visit http://www.vintagemacworld.com/lc_card_faq.html
or better http://www.vectronicsappleworld.com/app ... ecard.html ...

I will post my results with this card asap also in this blog, be patient.

I've needed to test floppy disk tools with my modern i7 equipped PC.
Unfortunately I have no real floppy drive built in.
So I "googled" for it, and I found one, which runs supposedly smooth with Windows 7 64bit.
http://www.ltr-data.se/opencode.html/#ImDisk
But the software "imdisk" is faulty. I've tested it by using/mounting an image file, created by winimage
( http://www.winimage.com ).
Try to install an 1.2MB or even a 360KB disk drive, go into command line, and try to format this new virtual drive with "FORMAT A: /T:80 /N:15" or "FORMAT A: /T:40 /N:9".
The result ? Always missing bytes, proof it with CHKDSK, e.g. formatting a 1.2MB disk results in 1.1MB total capacity.


So I restarted my search and found "vfd" at sourceforge: http://sourceforge.net/projects/vfd/
But this project is not supported anymore, if using 64bit Vista or Windows 7, you will fail to install the driver, even with "Administrator" rights.
This did the trick:
I've downloaded vfd_x64.zip from http://levicki.net/downloads/
I've looked for dsao13b.exe / dsao13b.zip - a tool for driver developer.
I started dsao13b, selected "Test Mode" (which allows to run non microsoft signed drivers), signed vfd.sys, and then started vfdwin with Administrator rights. That worked, I was able to format a virtual 1.2MB floppy disk running Windows 7 command line, see screenshot.

It works, but what an ugly way to manage it...

P.S.: You should change it back disallowing unsigned drivers to be working, if you do not need to use that driver. Otherwise you opened a new possible door for malware.

P.P.S.: Meanwhile I guess what's wrong with imdisk. Regardless of what I am selecting in imdisk.cpl, I got a "Partition" with a "start offset", not a "Floppy". Usually this happens only for a harddisk. See also this comparison:
