Re: BIT ONE OR BIT 99 keyboard controller needs

2010-06-03 by ullrich_67

Hi!

> you have  P805118  keyboard controller for BIT ONE and BIT 99...??? ..
> leaves to know me ...thanksLuc

I just want to let you know that I already emailed Luc privately and offered him a copy of the Bit One keyboard chip. Just for information: It is the same as the keyboard chip as in the crumar bit masterkeyboard that I have.

The original chip is a mask programmed 8051 microcontroller. The replacement part I can offer is a programmed 8751 (the more expensive reprogrammable eprom version of the 8051) programmed with the original code of the crumar bit one keyboard chip. Costs are 30 euro + postage/envelope (3.50 euro inside the EU).

After reading the group message via web only once a year I decided to be more active on this and other groups again, so I changed to direct messaging. Feel free to ask if you have some questions.

I have the white crumar bit01 and a crumar bit masterkeyboard.
You can see both on my homepage (link in the email footer).

Ciao
Peter
