Hello, all:

        This weekend I posted the latest code release for the Altair32
Emulator. Right now, it's feature-complete except for the Altair Integrated
Debugger, a fully-integrated debugger based on the one used by Jim Battle in
his Sol emulator.

        There are a few known issues with this release:

* Programatic access to the paper tape doesn't work properly for some
unknown reason. So, for example, using the toggle-in bootstrap loader to
load and run Altair BASIC 3.2 from tape doesn't work. Execution is never
transferred to BASIC. Loading BASIC in the form of a memory image still
works fine. Tape access has been sped-up by fully buffering the tape in a
buffer and reading from the buffer.
* Other BASIC versions, such as 8k (4.0) and Disk Extended BASIC,
don't work properly. They seem to crash the emulator after the "MEMORY
SIZE?" prompt. A quick trace of 8k BASIC shows some possibly strange IO port
usage.
* Emulated floppy access with the included disk images doesn't work
properly. I can boot the emulator to CP/M and are able to see the console
output but the CP/M BIOS doesn't seem to register console input. I've asked
for a copy of the CBIOS source that relates to the CP/M image (borrowed with
permission from the Sysun on-line computer museum) so that I can track this
one down. I suspect that it's a problem with the emulated status register
for the console serial port.

        Enjoy!

Rich
