Re: Which EEPROM chip should I get to burn a new ROM?

... Second important thing to remember: you will be NOT able to use microdisk controller together with above EEPROM - pin 27 is used to disable the ROM chip and in AT28C256-15PU this is pin has different function (/WE - write enable).... To use Microdisc controller with EPROM or EEPROM you can use ...

Re: Oric 1 and Atmos - repair help needed

Hi YuT666!

My personal opinion... Before check 6502, 6522 or ROM, I would check the RAM chips, in a 70% or 80% of cases, they are involved in the failures.

Changing RAM to an Atmos. In spanish only, sorry.

Re: Searching for 3" disk drive.

Hey, this is better! :D But the ICs HA16640NT and CX10040 are missing, them both hard to get. What a pity! :cry:

I really appreciate you taking the time, iss. Thanks a lot!

Re: Copy programs.

Hi Symoon!

Mmm, Nibble is a disc monitor only, and i think is very good indeed. BDDISK is good to copy from tape to disc, but is no good to copy from disc to disc.
