Memotech Hardware Repairs
Spare Parts
*** Disclaimer ***
I am not a dealer or trader in any form
other than as a private ebay buyer & seller - As a user of Memotech computers
I have needed to source some very old components, quite often
requiring purchasing in larger quantities than I need in order
to make them economic. This means that I have a limited number
of components that I don't envisage using that I am making
available to others who may be interested.
These parts are typically (exceptions
noted), "new, old stock" (NOS), that means that they are unused
components that were probably manufactured around the same time
as the MTX computer, i.e., they can be expected to be around 30
years old. Based on my use of similar components, more than
likely from the same batch, I believe them to be working, but
can make no guarantee as to whether the parts that you receive
will work on your system - there can be no refunds on these
items - you are buying them on the same basis that I did.
*** caveat
emptor ***
The prices for the chips here should be
quite a bit cheaper than on ebay, but if you can find them
cheaper, let me know and I will see what I can do for you. Where
I have a lot of spares, i.e., the DRAMs, I may eventually put
them on ebay myself to get rid of them, but in the meantime, I'd
like to give the Memotech folks first "shout".

P&P will be extra - pretty
much at cost (~£2.00 for a UK First Class "large
letter")
NB: the
postage prices are indicative only! Royal Mail
have started increasing their prices frequently
and well above the rate of inflation, keeping
tack of them is a real pain!
+NEW
- UK Postage IS now included in the
multiple quantity DRAM prices, i.e., for 8 or
more |
