[Sold] Zapwire HP48SX Expansion Port Interface with manual

[David Bengtson]

I purchased this back in the last century, and never used it. It's a plug in card for the 48SX that exposes the address and data bus. I've also got the manual, but nothing else. No idea how much it's worth. Best offer? The Blue wires are original, btw.

Thats interesting.

I have no idea what to offer though, I'll throw out $20

[David Bengtson]

Sorry, I got a higher offer. It's sold

Hopefully they will scan and submit the docs and info.

[David Bengtson]

I do have larger ones, but they're too big to put here. if you want to PM me your email address, I'll send them.

When I upgraded my desktop to Win10, I lost the scanning capability of my canon printer. I'll spend some time trying to figure out how to fix that, and I'll scan the docs.

[David Bengtson]

I've got the manual scanned. Shoot me a PM with your email and I'll be happy to email them to you.

I threw it up on dropbox

First time I've seen a full description of the LCD interface. Nice!
