Hi Josh, 1 - The early M100 ROM uses a non-standard pinout, so replacing it requires rerouting some of the pins; see m100y2k.pdf in Steve Adolph's folder at http://www.club100.org/memfiles/
2 - The late M100 ROM has the same contents as the early version but uses a JEDEC standard pinout, so a 27C256 type EPROM can plug right in. 3 - The 102 uses the same type of ROM as the late M100; the contents are slightly different but compatible. The board would work but unfortunately in the 102 the ROM is permanently soldered to the board, so if you want to replace it you have to unsolder the original. mike (not mark ;-) stein ----- Original Message ----- From: Josh Malone To: Model 100 Discussion Sent: Thursday, April 28, 2016 4:12 PM Subject: Re: [M100] Mark Stein's ROM Board Is this the board you're referring to: http://bitchin100.com/wiki/index.php?title=M100ROM Does this work on a model 102? I'm still managed to be confused about the ROM chip differences between early 100, late 100 and 102. -Josh On Thu, Apr 28, 2016 at 12:08 AM, Bill Nobel <b_no...@hotmail.com> wrote: Well, boards, Eproms and parts arrived and I tried it out tonight and happy to say SUCCESS TS-Dos burned first try and plugged it in and voila TS-Dos up and running. I need to remove the original socket from the 102 and Mount the board permanently though, I added a socket for the Eprom so I can change out Roms. Now I need to get the PC side up and running for comm, I still have Desklink crash as soon as I hit F4 on the 102. I am trying it from a HP Win7 starter 10 inch Netbook though.
