Re: Keyboard problem
The keyboard interface of the JR is different than on the IBM PC and compatibles. Software that uses the BIOS routines should work fine, but any software that tries to read the keyboard directly will fail. I think one of the differences is the interrupt used (NMI vs int1), so any software that tries...

Re: PC Jr expansion unit
I have one, do you want just the sidecar or the power brick also. The brick is the same as the one for the jr itself. You should still have my email if you want to talk.

Re: Atarii 800XL
I would skip the bean bags. Not easy for us 'seniors' to get out of. If you think you might want the 800XL, let me know. I am in no hurry to sell it.

Re: TI-99/4A
Don’t know why two are upside down. Trying again. 64150C27-3894-485C-887A-A37EEA2023F7.jpeg 0B95C8A8-EB4D-4865-BC04-66A455F0DCA3.jpeg 16 colors, one of which is transparent. It also has sprites. Transparent can be used with sprites and custom characters to let the background show through. Pretty nea...

TI-99/4A
Just putting this out there in case anyone else is interested. I recently bought 4 of these off eBay for about $100 after shipping tax, etc. Three of them had power supplies with them. I haven't tried the first one I bought because it sho0ws a lot of corrosion even without opening up. The other thre...

Re: Atarii 800XL
Atari, Commodore, and many other 8-bit computers use the same joysticks. They are digital so you really only reliably get 4 directions. You can get the diagonals, but sometimes hard to do. PC joysticks are analog. This allows finer control, but you have to calibrate them so they do nothing when cent...

Re: Atarii 800XL
I actually have three Ataris; 600XL, 800XL, and 130XE. They are all mostly software compatible. There are a lot of arcade style games, but not many RPGs, which is what I like. I actually plan on selling the 800XL soon. I also have a 1050 disk drive for it. Check out atariage.com or more information ...

Re: ParkIt Hard Drive Park Program
Chuck. I wonder if your are shutting down too soon after saving a file. Some systems cache writes to disk. If something on your system is doing this, shutting down without giving it some idle time to write the data can corrupt files. I seem to have a vague recollection of this issue from years ago. ...
