HEPAX-0C Prototype version ROM images.

[Diego Diaz]

Hi again,

This "BOOTROM" found in your tape directory has triggered my curiosity... Do you (or someone else) know where does it come from?

Sorry about the problems with your HP-9114A disk drive.

You will more likely get better assistance if you open a new thread requesting help to fix it.

This thread is too specific and most users/readers won't stop by (or read top to bottom).

Sorry not being on much help on that, I have never dug into such devices.

On the other hand (if you happen to have a PC with a standard 3.5" floppy drive) you may use "LIFUTILS", available here.

This utility alows you (among other things) to read LIF formated discs (like those from your 9114) on a standard drive and save the content into MS-DOS type files.

Regarding my service offer, it's obviously open to whenever you want... After all these years some weeks/months up or down won't make any difference. ;-)

I do have a question regarding HEPAX internal organization of the 10 bit words inside the standard 8 bit memory chips (RAM & ROM): I know they use only 5 bits (D0-D4) of every byte, which is the most logical arrangement BTW. But can you tell me which order are those bit placed inside every memory (even/odd) bytes? Provided you remember such details :-D

Keep up enjoying your re-found treasures!

Best regards from the Canary Islands.

Diego.
