Covox Sound Master card

Does anyone out there have one?  I've been thinking about building a clone, and I'd like to get some info about the card I can't find on the Apple II Documentation Project about it.

Proterm 1.1 vs 3.1

 I am trying to get ProTerm 3.1 to work on an enhanced //e and an Apple Super Serial Card in slot 2.  It seems like the interrupts don't work properly for ProTerm 3.1, as it only seems to receive a character when it is sending a character.   For example, if I type "AT"<enter>, I can sometimes receive an "O" or "K" if I press enter afterwards, especially if the baud rate is low, for example 300 baud.  I can use ProTerm 1.1 at 2400 baud and there seems to be no problem, except that ProTerm 1.1 does not support RTS/CTS and so going at a higher baud rate than 2400 baud results in lost cha

Anyone tested Disk ][ and controller card with AppleSqueezer GS?

Hello all - considering the AppleSqueezer GS accelerator for my ROM01 IIGS (Woz edition, ROM00 upgraded to 01 back in '86).  Niek mentioned to me that he hasn't tested the 5.25" Disk ][ drives with controller card - can anyone confirm if they work?  I still have two 3.5" drives and two Disk ]['s and would like to use them.

I'm suspecting mine is an early production IIGS, purchased in June '86, and might be affected by some of the sound issues mentioned by other folks.  I'll be forwarding pics of my motherboard to him to see if it's one of those.

Thanks in advance!

Need some help with the Einstein compiler

I have been using the Einstein compiler without any issues so far with quite complicated Basic programs, but recently I ran into a very strange bug when I tried to execute a DOS command.

 

To demonstrate the problem I have the following one line program, which simply executes the CATALOG command:

 

    10 PRINT CHR$(4)”CATALOG”

 

When I run it uncompiled under DOS 3.3 or under ProDOS it works perfectly. If I compile it using Einstein, the compiled version works under DOS 3.3, but under ProDOS it ignores the CHR$(4) and just prints on the screen:

Solid-state SCSI HD alternatives

Hello all,

 

I have an Apple SCSI Rev C - clone card, and I would like to use it with a solid-state SCSI emulator. I know of a few (such as SCSI2SD and BlueSCSI) but have no direct experience with any of them.

 

If you have such a setup would you mind sharing your experience setting up the SCSI solid-state drive and using it with ProDOS or other OSs?

 

Thanks,

 

Armando

Garbage on Screen after reboot

Hello,

 

I have an Apple //e and after a rebbot - most of the time - I have garbage on screen.

Sometimes with a blinking cursor and sometimes only garbage.

I try it 10x and perhaps it could be ok once.

 

Best

Video HW Issues - or maybe not?

 

Hello,

 

I've recently decided to revisit my childhood and acquired an Apple IIe platinum.  The motherboard says 1987 and International NTSC.

(I'm mucking around with 6502 assembler on my PC and debugging/emulating with Applewin currently)

 

I have no dedicated composite or Apple monitor, so I bought a no name composite to HDMI adapter. (I couldnt get hold of a vidHD :(  )

 

And here it what I have found :-

Any emulator which can save memory disassembly to file?

I'm using a Apple II program which loads in small sections as needed. I'd like to compare a disassembly listing before and after a particular section is loaded, but the emulators I'm familiar with only seem to show disassembly onscreen with no facility to save it to a file (at least as far as I can tell.) 

Can anyone suggest an emulator (for Windows) which can save a disassembled section of memory to file?

Thanks, Michael
