RE: Basic ROM for HP Portable Plus
Turbo Pascal was less successful.
The binary file from the zip (TURBO-PASCAL30.HAF) burned to a 27C512 ROM and verified fine. But once inserted into the software drawer, the PP does not find it or display it in PAM, even after a re-scan. It does appear in the directory listing for b: .
I did check the first few bytes in thge EPROM and it reads TURBO30 at location 00020.
It also hangs if I run turbo30 from the relevant directory via MSDOS
Am I doing somthing obviously wrong here?
