@MWTremblay on Twitter was asking me if I hung out regularly on IRC, and although I’ve written my own IRC client, that was a long time ago and don’t really use IRC much anymore. I mentioned that I use Twitter as my new IRC, and he said he was looking for something more compatible with an Atari XE. Challenge accepted! About a week later I found the time to work on that project and spent the day cobbling up a BBS door in Objective-C that would allow a user to send a tweet. Another...

While tinkering with my BBS this week I again found myself frustrated with a couple of bugs in tcpser. The first one was that it only worked with 8N1 data. A few of the comm programs on my more obscure computers have no settings to choose parity, and will insist on either doing mark parity or even parity. That meant that I couldn’t even enter the AT command to dial out.   An easy fix would have been to just strip the high bit so that tcpser would see the AT commands, but that would...

Update 2016 Jun 8: I was able to get the typewriter open and it is now working and printing A couple of weeks ago I picked up a Smith-Corona Memory Correct 400 Messenger at Goodwill.

This one has an external interface which can be connected to a computer using an external box...

Bad RAM on the IIgs A couple of weekends ago I was in the mood to do some retrogaming and didn’t know what I wanted to play so I asked for some suggestions from Twitter.

Unfortunately my IIgs has had intermittent issues for a long time, and it was looking like bad RAM might be the culprit.   The IIgs has an Applied...

I’ve had my dad’s first calculator sitting in a drawer in my desk for a little while. It’s a Hewlett-Packard 25 calculator with a red LED screen. My dad got it in February of 1976 at Macy’s and paid $207.68 for it. The calculator itself has a manufacture date of March of 1975. Not long after he got the calculator HP introduced the 25C which would save your program even after switching the calculator off which he said he would have preferred, but back then returning...
