Some questions on the WP-2 :
1) What are the specifications on the internal 32K RAM chip?
$50 at Radio Shack is way too much, but the manual doesn't
specify a speed or a part number so I could get a cheaper
source.
2) I glanced at the manual at a store - does the internal
RAM chip socket hold a larger chip than 32K? I thought
the installation picture showed a larger socket.
3) What phone number is available to order service manuals?garee@evax.arl.utexas.edu (Scott Garee) (12/14/90)

I can't help with the specs except one major: they are VERY low power RAMs. They always have power to them and must be as low power as possible. I haven't seen any 3rd party offerings yet, but I'm sure it won't be long before somebody comes along. > 2) I glanced at the manual at a store - does the internal > RAM chip socket hold a larger chip than 32K?

The 32k chip fits the socket exactly, I've heard of no other size, however, as with the 100's if we keep selling a lot of WP-2's someone will find a way to really boost memory capacity. > 3) What phone number is available to order service manuals? You cannot order them yourself, they must be ordered by a store from National Parts. It takes about a week or two to receive it after ordering. Most stores will require payment in advance or at least a deposit. -- +------------------------------------------------+ + Mail to: garee@evax.utarl.edu or call Scott at + + Radio Shack 01-8323 Arlington, TX 817-649-2518 + + If I can't help you, you're in it really deep! +

I'm not sure if they are WIRED on the board, though. It appears not. Like they put a 'standard arbitrary EPROM socket' on the board, even though they wired it for EPROM-pin-compatable RAMS of 32K or less only. Joe

I checked at the store and learned once again not to trust my memory. Sorry for the bad info people. And to think I hadn't made a mistake in 20 minutes! -- +------------------------------------------------+ + Mail to: garee@evax.utarl.edu or call Scott at + + Radio Shack 01-8323 Arlington, TX 817-649-2518 + + If I can't help you, you're in it really deep! +

Being an employee didn't help, actually I think it lessened my chances. Most Tech Ref manuals DO NOT contain programming info, but I haven't seen one for the WP-2. Several people on the net have inquired about it, so if anyone has gotten one they might be able to shed some light. It's too bad that Tandy won't help, I think they should provide you with the info, even if they do charge a little for copying fees or whatever. Did you speak with someone in Ft. Worth? Often, more can be accomplished with them through the mail (US). Especially middle mgt and up because of the numbers of calls they recieve daily. I hope you can get the info you are seeking and I think WE should provide it. -- +------------------------------------------------+ + Mail to: garee@evax.utarl.edu or call Scott at + + Radio Shack 01-8323 Arlington, TX 817-649-2518 + + If I can't help you, you're in it really deep! +
