![]() The supplied cpm22 system (drive A) does not support generic kermit so I assume that IOBYTE is not implemented. This transfers the files into the emulator, but does not allow export back to the host pc. Place the required disk (dsk) images in a “data” folder under the Altair880 folder of FabGL-master and ensure the names match that in the Altair880 sketch (diskC.dsk and diskD.dsk). Use the plug-in tool ESP32FS ( ) which puts a tools option in Arduino IDE (ESP32 Sketch Data Upload). This can transfer disks in both directions.Ģ. I had problems getting python serial working under Mac OSX and Windows, but worked fine under Raspberry Pi 4. use the tools provided by FabGL - the python “transdisk” tool and the menu option on the cp/m emulator under ESP32-VGA (invoked by Pause-key then S or R) to transfer 338k Altair disk images. I have identified two ways to populate C and D drives:ġ. These drives are read-write and exist in SPIFFS storage within ESP32. I thought, from browsing the code of the altair8800 sketch, that drives C and D would be populated by default, but I have not achieved that yet. īy default the system is configured with two pre-populated disk images on A: and B: which are read-only (I assume that is because of limitations imposed by the memory used for storage - I shall investigate this further) The console is by default assigned to the physical VGA monitor and keyboard attached to the TTGO ESP32 VGA but can be redirected to the USB port (serial) via the cp/m command STAT CON:=UC1. The ESP32 VGA FabGL Altair 8080 CP/M emulation is a functional CP/M computer with the equivalent of 4 floppy drives (using Altair 338kb dsk images) compatible with images from the site.
