February 5, 2015 – Radio Shack Files for Bankruptcy

Radio Shack has filed for Bankruptcy. Although Tandy / Radio-Shack had long ago sold off any interest they had in the TRS-80, it is still a sad day. I am sure all of us have fond Radio Shack memories, most likely sitting there messing around with their Model I display model. Farewell Radio Shack.

April 13, 2015 – Site Resign, Kinda

Google has been whining that the site is not mobile friendly, so I have been looking for “Responsive” WordPress themes that will work without incredible problems. The new one, called DW Minion, seems to do that, although it will need to be configured, which will be slow in the coming.

The old posts definitely look bad, but since there are about 622 of them, I don’t intend to clean them all up.

Otherwise, I am still reading disks for people, sending DOS disks to people, sorting through thousands of disk images, etc. I hope to have another set of eBay auctions soon.
