Re: [M100] REX second source

Steve, when you say you have to grind the boards, do you mean you grind the long sides down to cut the 28 large through holes in half? That right there is a great example of what I mean by letting the community/users help improve the design. If the cad file were up in a git repo, or just

Re: [M100] Belt Repair/Replacement Info -> CCR-81 CCR-82 PDD

For PDD-2 I used "FRW-8.5" from a random ebay seller. It's a generic size code that several sellers list, so you just add "belt", to google "FRW-8.5 belt", and buy from whoever you like. I found the number in a old archived forum or newsgroup post, a text file in the club100/bitchin100

Re: [M100] Praise for REX

I don't think anyone is *producing* an option rom board, but there is a board up on OSHPark that anyone can build themselves. I have built a few. They are easy and cheap to build. And they are re-writeable, although you need an eprom burner and a test-clip or a special programming adapter to

I could make that very same consideration argument. I could say most people, especially new people, are already on facebook anyway for their relatives and theater groups and event notices and kids schools and crap, and so it's more considerate to more people to just post something there rather

Re: [M100] Praise for REX

I don't think it shows on the outside. But I've never seen one so who knows? I just know that the multiplan rom is utterly unnlabeled and the chip is even the same as some of the system roms, just in a carrier. Have to power it up and see a basic choice on the left hand menu and not multiplan.

btw sorry for derailing this thread, which was originally about praising the rex, which for all my sideways criticism that I can't get one, probably does deserve a lot of praise. I moved my model 600 conversation to a new subject. -- bkw

[M100] Model 600 opt rom

Checked out the pinout. The Option rom socket is physically the same as 100/102/200. But the pinout is different. The pinout for the socket on a 600 is the same as 27256, taken from the data sheet for HN613256P. (which is a mask rom where the only difference from 27256 is pin 1 Vpp is NC) So

Re: [M100] Help Imaging a ROM

Replying a little more explicitly to your first question, "is that pinouts.txt file correct?", yes it is. I used it many times both to dump commercial option roms in a TL866 programmer, and while helping design the various FigTronix adapter boards which let you make your own option rom from a

Re: [M100] Help Imaging a ROM

If the machine is a Model100, 102, or any of it's cousins, the system rom is already available for download unless it's a some unusual non-English variant. If you are talking about the option-rom, those unplug, no unsoldering. And, many of those are already dumped by someone else long ago too and
