ELKS seems like a good candidate; it's just subject to the standard PCjr problems - the video window and keyboard handling are probably the biggest problems. (I'm assuming it uses the BIOS for floppy drive or hard drive access.)alanh wrote:Has anyone ever run Minix, early Coherent or QNX, PC/IX, Venix, ELKS, or Idris on a Jr? They all supported generic 8086/8088 systems at one point. Though impossible to offer memory protection or demand paging, the segmentation scheme does act a bit like a rudimentary MMU for 16-bit relocatable virtual address spaces.

Re: Terminal Into PCjr
I'll try to go step by step.
Attempting to copy Clock.exe 6.87k (ds1216e clock files)
fresh boot pcjr
Load DOS 3.10
Mode com1:1200,n,8,1 {ENTER}
on Toughbook
Connect teraterm via serial but do not ctty
Teraterm reports com1 connected, no display
On pcjr:
copy com1: clock.exe (Wait to press enter)
On Toughbook
Select [send file...] menu
Select [clock.exe] flie (wait to click open)
On pcjr
(hit ENTER)
On Toughbook
(click open)
Wait monitoring both screens.....
ON pcjr
Read Fault error reading device com1
Abort, Retry, Fail?
(seems to happen right as the file gets to the end on this one)

Hi-ho, KERMIT the computer file transfer/management protocol here.

That's not going to work ... don't even try it.
Programs are binary files - they contain all sorts of data in them. If you transfer a program like that (in ASCII mode) it's going to be garbled and it will probably crash the machine if it manages to load.
Short story - you need something like Xmodem, Ymodem or Zmodem on both sides to transfer program files.

Re: Terminal Into PCjr
found a disk with a program called Bit-Chat 1.0 By Incomm Data Systems in my trunk.
Seems to have an xmodem protocol but i can't seem to get it to work.
Can't find any documentation for it anywhere.
Anybody run across this before? Any Insights?
