My Miggie 2K

[irishmike]

I have not had a real chance to sit down and play with my new Amiga 2k.  I am borrowing a C= Monitor (but eventually plan to purchase Jens' Indivision VGA adapter when it is released).

I acquired the 3.1 ROM for the unit and I am looking to install a new RTC battery.  The old one having been removed to prevent PCB damage.  I have been advised to perhaps use 2 AA batteries, but wanted to find out if anyone has ever used a button cell and what might be involved in installing that kind of solution.  For example:  would I need to install a diode to insure that the system does not try to "charge" the CR2085?  Should I worry about this same kind of issue with the 2AA cell holder idea?

Also I am thinking of installing a SCSI CD-ROM and I am not sure if I am going to put it inside the case or just find a nice external model.

Help/Suggestions always appreciated.

@damion:  Would like to see the pic.  Thanks.

So I guess the remaining question is, do you place the diode on the postive lead or the negative lead...I assume you want the direction of current flow towards the mainboard if on the positive lead preventing the charging circuit from being able to reverse the polarity if the voltage drops?  I have not decided whether or not I want to mount the holder on the mainboard or attach leads, that I will determine at a later time.

@Matt H:  That would be great if it weren't sold out!

@everyone:  I have ordered my parts from Mouser and I decided to go with the vertical cr2032 battery holder and diode, I think it may be a little easier to orient my setup this way.  The cost of the parts was like $2 USD... the battery will be around $4 USD so for $6 I have a workable replacement.  I did figure on something like beast96GT's setup.  That doesn't look bad at all.

I still have thinking to do on my particular setup.  BTW:  forgot to mention that shipping was terrible on this order... it cost triple the cost just to have the items shipped USPS from there so I need to remember that if I want two small parts in the future... oh well, for the love of the Miggie!
