Cheers

Hi
I'd had this AppleIIe for a number of years but no
disk or operating system.
It didn't have a SuperSerialCard ( SSC ) so transfering data would
have been fun. I'd recently found that I could have used the audio
through the cassette but I'm told it is slow and would take
a long time to do simple stuff.
When I got my IIe it came with one goodie. It had a QuikLoader
board. I'd been searching for a manual on it for quite some time
I'd finally found a fellow in France that had it and the disk set that
goes with it, just a few weeks ago.
I discovered that the EPROMs on it had both DOS3.3 as well as ProDos
Having DOS3.3, I could at least INIT disk. Still, I needed the SSC
to do serious down loads.
Before I'd done much with it, I'd recreated a SwyftCard from a proto
board and parts. It has been fun but only useful as an editor for
non-standard disk.
Well, I'd finally located a SSC and only needed to make up a cable
from the 10 pin header to a serial connector.
I then started searchng for some code to download. I found that
there was quite a bit but all in squished format. The ADT program
only take expanded images. On seaching some more I found that
the CiderPress tool would expand it for me.
Now for the next problem. Getting the client software onto the
Apple. My windows machine has no serial port and I have no idea
where the USB to serial adapter has got to since my last move.
I know it'll show up so reluctant to buy another.
The machine I intend to use for the transfers has DOS but no
com software.
After some thinking, I decided to enter it by hand onto the Apple
( not a good thought though ).
After several hours of typing, I finally got it all entered. Luckily,
I used the DOS3.3 on the QuikLoader to save a copy. On first
attempt, it just crashed.
I realizes I needed a way to check the code. One the PC sde I
quickly though to gether a check sum program that displayed
the code offset, the byte abd the sum. This was kind of specialized
to match the format of the file that came with ADT.
On the Apple side, a quick check of the manuals showed that
the BASIC might interfer some with the location used by ADT
so I loaded it at $4000. Nice that Apples BASIC/DOS lets one do that.
I wrote a similar program on the Apple, to do the same as the
PC program ( in BASIC ).
I was astounded by how slow the Apple was compared to a 10 year
old laptop. I could do the entire check sum on the PC about as fast
as I could type the return. On the Apple, it was slow enough that
I needed to partition it.
I'd thought I'd only made a few minor errors. In earlier days, I'd
entered bigger programs with no errors.
As I got to work comparing check sums, I realized that age my
have caught up with me. I found at least 3 lines that I'd most
likely type the wrong address for. All totaled, about 48 errors
in 3K of code.
Thank all that I had a disk to save images on.
I finally got ADT up and running. Down loaded some useful
software and had a good time.
The one thing I found is that the BASIC on the Apple is really
slow. It is about the slowest I've ever used. How people put
up with it I don't know.
