- The following two files are my Epson PX-8 ROM maker, written in TURBO
- Pascal. It has two commands, I to initialize a file and C to copy a file
- from the CP/M host system's disk into the ROM image. You wind up with a file
- called ROM.DAT (or somesuch; it's been a long time since I used it) that is
- a binary image of the ROM. I've misplaced my utility for turning that into
- an Intel .HEX file, so I'm not posting that one.
-
- Once you've copied a file into the ROM, you can't delete it; if you make
- a mistake you have to start over.
-
- It also doesn't handle the special case used by the WordStar ROMs, wherein
- a portion of the first KB that does not contain FCBs can contain data. In
- other words, you can't upload the WordStar ROMs, patch WordStar, and then
- use this program to build it back into a ROM of the same size.
-
- The program also only generates ROMs with 32 FCBs. I don't recall why I
- didn't prompt for that; there may be some reason beyond the obvious. At
- any rate, I've never built a ROM that needed more than 32 FCBs and 32 FCBs
- fills 1KB, which is one of the reasons that it can't rebuild the WordStar
- ROM.

- Enjoy,
