I am posting this for a friend and need an answer as soon as possible.

My friend has an IBM-PC Jr. and is looking to add on a 512K expansion
board.  There are two possibilities that my friend knows of -- Quadram
and Tecmar-Vawe(?).  (Are there others?)  Unfortunately, the sales
people can't tell my friend which is more suitable, which works better,
which is the best value for the money.  They aren't even sure if either
of these expansions are compatible with the PC Jr.!

So, what do you recommend?  Has anyone had any experience with either
of these expansions, or know of someone who has?  Are there any other
options?

Please reply A.S.A.P.

Thank you.

Well, I got lots of notes when I mentioned the eprom programmer
card for $99 so rather that reply to each I thought I should post the
information so it reaches all.

A place here in Toronto (no affiliations) called Exceltronix offers an
EPROM burning card that handles the 2700 series of eproms including
2716, 32, 32a, 64, and 128's. It is an IBM PC full size card with two 
sockets for the 24 and 28 pin eproms. You can optionally add a serial
port to the board if your PC is short of them. The software to do the
programming is included and yes, the source is included too for the
hackers. Other options they offer are ZIF sockets for $40 extra
or ZIF sockets on an external card with ribbon cable so you don't have
to keep opening you PC to burn an EPROM, $69 extra. The optional serial 
port is $49 extra. The board generates all the necessary voltages
from the standard PC supplies. All prices here are accurate as of their
1986 computers and components catalog.

The Toronto store and mail order address is
319 College St.
Toronto, Ontario
M5T 1S2
(416) 921-8941

The prices are in canadian funds, add $5 for shipping (UPS). They accept
visa, MC, Am. Exp., Diners Club. I have dealt with them often since they
are just down the street from the university. They are reputable.
