IBM 1401 core memory

See the page, and the talk page. Thanks for the push, I can probably find more/better refs, but I think this is a good start. If you wanted to help you could email a few of the principals at the IBM 1401 Restoration Project and get pointers to the actual IBM docs that give this info. Jeh (talk) 00:51, 16 July 2012 (UTC)

Problem with your custom signature

You have a custom signature set in your account preferences. A change to Wikipedia's software has made your current custom signature incompatible with the software.

The problem: Your preferences are set to interpret your custom signature as wikitext. However, your current custom signature does not contain any wikitext.

The solutions: You can reset your signature to the default, or you can fix your signature.

Solution 1: Reset your signature to the default:

1. Find the signature section in the first tab of Special:Preferences.
2. Uncheck the box (☑︎→☐) that says "Treat the above as wiki markup."
3. Remove anything in the Signature: text box. (It might already be empty.)
4. Click the blue "Save" button at the bottom of the page. (The red "Restore all default settings" button will reset all of your preference settings, not just the signature.)

Solution 2: Fix your custom signature:

1. Find the signature section in the first tab of Special:Preferences.
2. Uncheck the box (☑︎→☐) that says "Treat the above as wiki markup."
3. Click the blue "Save" button at the bottom of the page.
