Mike's PCjr Page

Thank you for all your help.

Thanks for all the replies. My original question was: since this new sidecar is not posting when the pcjr starts and jrconfig will not recognize it but says that I do not have enough ram, does this mean the sidecar is not working or should I try something else? Thanks.

According to it's ebay description it was an ibm 128 side car modified to 512k. It came without an outer cover (just the board) so I put it in a spare out cover. jrconfig need 256k to run so I have tried the 512k sidecar with tecmar captain (128k) and cadet (also 128k). In addition to this I have tr...

I just purchased a modified 512k side car off ebay. It seems as though it could be bad. When I use jrconfig.sys it only displays the ram on the post screen 384k but says ram above 640K is available and to use /L in my config.sys. config.sys looks like: device=jrconfig.sys /L and still no luck. Any s...

A while back I purchase jrcaptain and jrcadet off ebay and it came without a power adaptor. I ended up getting one through jameco. Its product number is 112336 and its model number is adu090150. It has worked very well for me in lieu of the original adaptor.

Thanks for the replies, My PCjr (recent purchase from ebay) is has legacy "blinkenlights" and the internal card bumps me up to 384k. I also have tecmar captain and cadet attached. The computer reads 384K but when I boot with dos with legacy refresh games that did not have enough memory run...

Could anyone recommend a good site to download pcjr-ready games. I have a few files that write to disk (on a pentium 3) and load but appear to be tandy versions and do not run correctly or at all on the pcjr (fine in dosbox). Games I am interested specifically are tapper and striker, any other resou...

I was able to format the 720k disk to 360k. The pcjr did not give me any messages with format but it did not load the files either; it just gave me a blinking cursor. Am I missing something? Thank you.

I kind of figured when I saw the card in person that it probably wasn't going to work. Thanks for your response Mike.
Here is a picture of the 192k card.

To make transfering files easier from a modern computer to the pcjr I put a 3.5 720kb floppy in the pcjr. I have a dos2.1 image file on the 720kb disk but the pcjr says it is not a bootable disk. It is formatted as FAT 12bit. Does any one have any suggestion of how to proceed?

Thank you
