Why can't I run AxoBASIC v1.1 after upgrading to a Pentium computer?

AxoBasic 1.2

Question

Answer

Pentium computers sometimes use additional ROM BIOS from network cards or other devices, which are placed into the E segment (E000 - EFFF) of the UMB (upper memory block), previously required by AxoBASIC v1.1 for use as an EMS page frame. However, with AxoBASIC v1.2, the EMS page frame is relocatable, and the HARDCOPY buffer from the D segment (D000 - DFFF) of memory has been eliminated. So now, not only is there more memory available in the UMB, but the EMS page frame can be moved to any part of the UMB.

Although further development of AxoBASIC has been discontinued, AxoBASIC v1.2 is available as a free update to all AxoBASIC customers, along with a manual in MS-Word format. Please contact Technical Support to obtain these. Note that AxoBASIC v1.2 has not gone through beta testing.

Version 1.2 supports conventional VGA graphics systems. Two data acquisition systems are supported: Digidata 1200 series and LabMaster TL-1.

Version 1.2 includes some new functionality, including:

1. STARTEVOKE allows a user to start an indefinitely concatenated series of EVOKEs under DMA control; during the stimulation and acquisition, control is returned to the user program to allow analysis of data as it comes in.
2. TSAMPLE allows a SAMPLE to start after an input signal passes a defined threshold in a specified direction.
