Apple II

I've been mucking around with CiderPress in an attempt to copy over some .po hard disk images to the compact flash card for my MicroDrive Turbo. In Windows, when I load CiderPress and attempt to go to File > Open volume, I am unable to open the CF card as a physical disk. It is listed, however, when I attempt to open it, I get an "Access Denied" message.  I can, however, open it as a logical volume.

The instructions with the MicroDrive Turbo are specific about opening the CF as a physical volume. Any ideas why this error is popping up?

Howdy,

I've scoured the internet and cant find any options for an Apple IIe => HDMI  video adapter. 

My Apple IIe is a platinum version, and I think the color NTSC signal may only work with a special Apple Color monitor, but I'm not sure (I'm very new to rediscovering the Apple II).

I tried a couple of compositive to HDMI adapters from Aliexpress.  Only one of them 'works' reliably, and that is only when I'm displaying text.  During color display, the converter cannot sync 

properly and colors are not displayed either.

 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

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:
