Power Supply Requirement for Tandy Portable Disk Drive (3.5) , 100 and 102

[Caterpiggle]

HELLO TO YOU ALL,

 

I need to know if it is safe to use 3rd party Power Supply called "Recoton" and model AD-100. Specification : 6 watts, 100 mA or 300 mA. Range between 3 volts all to the way to 12 volts. So I choose 6 volts for Tandy Portable Disk Drive , Tandy Portable Computer 100 & 102. So my question , Is safe to use this 3rd party power supply to plug any of those 3 devices ?

 

Yes, I realized that Disk Drive required to have 400 mA instead of 300 mA. I see , there it is conflict between original Tandy Power supply say, 8 watts compare onto the lable 1.5 watts (drive).

 

I hope you would be able to answer my questions above.

Original power supply is 400mA. 300mA is probably close enough for the computer...considering it can run 20+ hours on 4 AA batteries.

I'm guessing the floppy drive is going to be far more power hungry.

You do need to make sure you have the correct polarity.

Personally, I would find a 6 vdc supply rated 400mA or higher.

Hello Turbo-Torch,

 

I found out on the info on Wiki - Tandy 100.

 

It stated "Power Four penlight (AA) cells, or external power adapter 6V (>180 mA)". Of course, it does not saying anything about limited watts ? My 3rd party PS is 6 watts. So is it safe to using on Tandy 100. Is polarity in negative or positive ? Is Tandy 102 has the same power supply requirement as 100 ? Thank you for response back

 

How should I know which shape in power tip in plug ?

My adapter is catalog # 26-3804. I don't own a 102 but I believe it uses the same adapter.

I'm looking at the adapter and it shows the outside of the barrel as positive and the inside as negative.

Whatever barrel adapter fits snugly is the one I'd use. Just make sure you have the correct polarity set!
