Re: [M100] next project!
Thats really cool! To bad, it doesnt work for NEC. -- Kind regards / Mit freundlichen Grüßen Pawel Radomychelski -Original Message- From: Stephen Adolph Reply-To: m...@bitchin100.com To: m...@bitchin100.com Subject: [M100] next project! Date: 03/02/24 03:44:53 I have so many Model T around here-- too many! One of the reasons is for testing, but another reason is because I have different computers for different use cases. For example, I have an M100 set up for CP/M using an NSC800 CPU using REXCPM, and of course I have a normal M100 with 80C85 CPU again with REXCPM. So, I've decided my next widget is going to be a dual CPU card for M100, so I can have Z80-based CP/M and normal M100 in the same box! Here is my proto board. It uses a great big CPLD to interface and manage the switching between the two processors. It also will support dual clock rates because... why not. I'll post updates as this progresses...

[M100] selling some laptops
hi everyone, I'm selling some computers. I simply have too many! What I have for sale is listed here. https://bitchin100.com/wiki/index.php?title=Ordering_Information - computers are re-capped and tested - new NiMH RAM backup battery installed - boards are repaired if needed (either from leaking caps, batteries etc.) - for M100, serial port resistors swapped to 330 ohms if needed - LCD contrast pot replaced if needed - RAM memory is maxed out - keyboard is tested - serial port and printer port are tested You can add on things like a REX# or REXCPM, clock doubler etc. Otherwise it will be a stock machine with full RAM. Just email me if you are interested. thanks, Steve

A double-barreled M100. That’s a big step forward. /Sign me up!/
