Re: Parallel port CDROM drive

I think I will shelve this for now. I may consider a parallel to SCSI interface at some point and try again.

Re: Development Environments (Was:Starting a PCjr coding project

Microsoft Macro Assembler 5.1 and Turbo Pascal 5.5 work just fine when set up on a zip drive.
Microsoft QBasic also works great although it is interpreted.

Re: New Telnet client for old DOS machines

Well, I got my Xircom adapter in today's mail, so I went ahead and modified my extra printer port sidecar for bidirectionality and LPT2 and it passed the test. However, I noticed that when I fired up the PCjR with the Xircom adapter connected to LPT2, then that port was not recognized. So what I end...

BASIC SCREEN command

Hi.
I noticed that when JRconfig is running, I am unable to access the high resolution SCREEN modes such as mode 6 for example under Cartridge BASIC. Is that a known issue and is there a solution to it?

Re: New Telnet client for old DOS machines

OK you got me fired :) I located a Xircom parallel adapter on ebay and I made an offer for it. Asking price is $56 but I think I can get it for cheaper. I actually do have an extra printer port sidecar, so I will modify it for LPT2 and make it bidirectional per your excellent instructions, and this ...

Re: New Telnet client for old DOS machines

I have been using baud rates of 19200 so far without any issues, and this is more than sufficient for telnet activity. I mostly am interested in telnet so I can connect to BBS's out there, and I have a couple that I regularly visit. I looked at the Xircom adapter, and it does not have a pass-through...

Parallel port CDROM drive

Hi. Has anyone here ever succeeded in getting a parallel port CDROM drive to work on the PCjr? After reading about using a parallel port Zip drive on this forum, I bought the Palmzip driver and got my Zip drive to work (albeit a bit slow) which allowed me to use it a hard drive and install a bunch o...

Re: New Telnet client for old DOS machines

I see that the requirements for running the telnet client are not exactly commonplace, but there is an alternative if you happen to have a Linux box. Linux allows you to connect a remote console via the PC's serial port and run an independent session that way, and so all one has to do (after some mi...

Re: PCjr Telnet BBS is up for testing!

Hi. It looks like the telnet link is not working. Is that project still alive?
