DIE FLOPPY DIE!

Submitted by glb_gtz on June 28, 2006 - 2:01pm

I have been unable to fix the booting issue with the floppy. When the floppy ROM is loaded, ProDOS refuses to boot. Without the ROM, ProDOS happily boots from the LPC ROM all the way into the BASIC Interpreter. From there I am able to copy files from the ROM drive to the /RAM drive in the second 64K memory bank. The 80 column text screen works perfectly also. Both of these features require the use of the memory switches, so I believe everything is working correctly. Because of these successes, I convinced myself the issue was related to the floppy emulation.

One user I look after has an enormous number of this line item in the console:

"error evaluating Type 4 function: typecheck."

We use Adobe Creative Suite 2. A quick search via Yahoo found 2 other people posted this error but no answers as to why it happens. Best lead is currently at:

Success at last

I was finally able to boot ProDOS! The big holdup seemed to be the floppy emulation. As soon as I disabled the floppy ROM, it booted into ProDOS and the basic interpreter. ProDOS seems to do something with the floppy even though it is not the boot drive. ProDOS also sees the extra 64K of memory and sets up a RAM drive. I am trying to decide what to do with the extra 384K of RAM. Originally I was going to set it up as another RAM drive, but I have been thinking of setting it up as additional banks of memory like the RAMWORKS card.

A lot of crying

Again crying / testing about the same.

It's all over excpt the crying

Crying .... Testing

To me about the same. I have been unable to boot the Apple ][ E ROM. But today I finally found the smoking gun, so I believe it will boot the new ROM set tonight. I have a 1000 KB ProDOS image on the ROM and the slot ROM code is being loaded also. With a little luck, it will boot completely up into ProDOS. I also have the floppy slot ROM loaded so I might be able to start testing the floppy emulation. That is the next big hurdle.

Getting closer

I have fixed most of the video issues and can reliably boot into Apple ][ mode. I was planning on posting some pictures, but I got side tracked. I finished the 128K memory code and also finished the Floppy disk emulation. I say finished, but it really is not finished until it is tested. I have done almost no testing on any of these new features. The memory I can test using an assembly language program. I am working on it now. When the memory code has been tested and debugged, I need to switch over to the Apple IIe ROMS. This will give the 80 character display capabilities.

It is alive

Well...mostly. Yesterday it looked like it was trying to boot. I was getting a ] at the bottom of the screen when I hit the RESET button. But the screen would not clear and the keyboard was not working. I should have cycled power and I would have gotten the screen to clear. Something about cold booting and warm booting. Today I fixed the keyboard, except for the space bar. And now I can run BASIC programs. I have not done much testing, but I have some issues that I need to fix. Of course, I need to fix the space bar. Also, the character K is replaced with G. Both if these are easy fixes.

Projects

I've got a backlog of projects, including:

1) Get my QRAM 1M Apple //e card tested and installed

2) build out my replica 1 Kit

3) Get 6 Apple 2s hooked together for some Music
synthesis, I've got 2 MIDI cards kits, but need
some 6850 and other chips.

I've got one Mountain Computer Music System (with light pen!)
Also have 2 Novation Apple-Cat cards now (8-bit D/A for more
elaborate sample playback.)

4) Put the 6522 on a prototype card, maybe along with
an FPGA if I can find the right kind of socket.
