You're probably right; note that the HHC ROMS only had 24 pins. On Mon, Mar 7, 2022 at 9:21 PM Brian K. White wrote: > On 3/7/22 17:05, Stephen Adolph wrote: > > > > > > > https://www.ebay.ca/itm/255421613953?hash=item3b78508781:g:dAYAAOSwfbFiJS8J > > < > https://www.ebay.ca/itm/255421613953?

There is documentation how to build the cable, somewhere on club100 or bitchin100 or in the M100SIG archive. Unfortunately it's an active cable with electronics in it. It converts from rs232 to ttl, and does a peculiar dirty trick to rob power from the rs232 port. http://ratthing.com/club100/tpdd.

I've managed to find the utility disk for the portable drive(I don't know which drive I had). Still haven't found the drive, yet, though, if I still have it. I don't know much about electronics, so I don't know if I could build a Rex myself. I think Rex is interesting because it opens the Model

The dos that comes with the disk drive is loaded from the disk drive from a file on disk (the first time), and you have to kick the process off by typing in a tiny bit of BASIC manually first, which does listen on the com port. You need the Utility Disk that came with the drive, or a copy. If you h

Monoprice 479 -- good to know for future reference. Thanks. The DOS I used was pre all of that. I'm talking ancient. I think it's the one I got from Radio Shack with the Floppy when I bought it. It was fairly basic, I think with a simple menu to load, save, delete on floppy, and I think I do r

Re: [M100] Mystery Rom in Option Rom slot

Too late now I guess, but just get a Monoprice 479 for $2 and it's the perfect cable for M100/102/200/600 to a pc all pre-made molded in one piece. No null-modem adapters or gender changers needed. If you need a usb-serial adapter on the pc side, anything works. They all have the right 9pin, male,

Re: [M100] Mystery Rom in Option Rom slot

The EME logo might indicate that underneath is a standard 27c256 eprom. At one time, EME made a flexible PCB that wrapped around a normal eprom and re-mapped the pins to match the optrom socket. I have been able to re-use these so even if the ROM isn't useful any more, the EME PCB may be. Kurt

Re: [M100] Mystery Rom in Option Rom slot

I'm fairly sure it's probably the DOS for the floppy drive now. When I do call 63012 it prints a line feed and just waits there like it's looking for the floppy drive. I've ordered some parts to try to make a null modem cable to connect to the PC. I could probably write a program to send the

Re: [M100] Mystery Rom in Option Rom slot

The rombo is a generic device that can have any rom you wanted loaded on it, like a thumb drive. Doesn't have to be written by or even licensed by EME. And there are a few different roms that had disk support in them. After re-seating, call 63012 still didn't work any better? If you're really cur

Re: [M100] Mystery Rom in Option Rom slot

The only thing that I can think of is, it might be the DOS for the portable floppy drive which I had at one point(I still might somewhere). I don't know if EME systems was ever involved with that or whether the portable floppy drive required an option ROM to operate. On 3/13/2017 12:54 AM, Mike

I pulled the option ROM out and plugged it back in and tried printing chr$ of $ to $8000 again. I'm getting something different now -- no alternating patterns, just a bunch of random chr$, so something is there. I didn't see any recognizable English words, though which is odd if there was so

Thank you for that program. I tried print chr$ the option rom address $ to $8000 and there are some stuff at the very beginning, but nothing identifiable and then it's just pages and pages of mostly ";" + 0 (59, and 0). Weird... The first bytes starting from $ are 56, 191, 239, 255, 19

Thanks for your suggestion. I tried print(chr$(i)) from i - 0 to 65535 and all I see is the usual microsoft stuff and BASIC commands in standard ROM and the screen menu items. Doesn't the option ROM reside at the same memory address as the standard ROM and can only be accessed by memory switch

You could try writing a little FOR loop in basic to PEEK the memory and print the contents. Perhaps something like FOR I=62000 TO 65535: PRINT CHR( PEEK(I)); : NEXT then look for something readable like "Option ROM (C) 1986 Club100" ... or whatever. You might need to change the starting and
