[sci.electronics] Memory expansion for Radio Shack Model-100

jasba@ghp.UUCP (Jasba Simpson) (07/06/90)

I own two model-100 radio shack laptops.
I'd like to upgrade the memory on these, they are
presently at their minimum of 8k.

I've been trying to get the part number of the chip,
with little luck. Could someone please fill me in with this
'industry' secret (you should hear the excuses Radio Shack comes
up with).

Thank you,
Jasba

Jasba, As I remember, the chips are a sort of piggy-back hybrid. The
original ones consisted of a ceramic substrate, with 2 flat-pack chips
soldered to the top of it.

You are in luck! A company called Purple Computing sells upgrades, 
and other accessories for most laptops. I have once purchased upgrade chips
for my model 100, and they work fine. I think they were half the cost RS
charged (years ago). Numbers I have for them are 800-732-5012, and 
805-987-4788. Good luck!
