Trying to SYSGEN RSTS/E and failing
Following a build guide. But when I get to step 15 it want’s me to drop out to simh, by pressing Ctrl E so I can attach a drive. Which I did a few prevous times in the SYSGEN. Except now it’s not dropping out…just displays ^E on the screen. Pressing Ctrl Z exits ungracefully. …
Created better EBCDIC Basic-Plus conversion program
I believe it’s more readable and efficient than my first attempt. I translated my julia style EBCDIC table to a more convential Basic way by using DATA statements. I didn’t borrow Jay’s data statement’s like I said I might. Mainly because he used hexadecimal values in his program. To me that’s an extra conversion step …

Dumb Basic-Plus coding mistake
I was adding a line feed to a print character if something occurred. But it wasn’t working. Why? That’s what I do in Linux, and this is running on Linux. No…it’s running under Linux and the Basic-Plus environment uses CR+LF like MicroSoft. I should say MicroSoft uses CR+LF like DEC.

I guess it’s still sometimes Fatpack
I thought Flatpack had fixed their excessive size problem. Apparently Not! At least not always. I installed Solitaire and Mahjongg (sometimes spelled Mahjong) last night. Two old classics that I sometimes like to play. And Mahjongg’s Flatpack was a 942.7MG download (2.3GB disk space required), almost 1 GB download for a simple game? Thank goodness …

Read IBM tapes on PDP-11/70 with Basic-Plus
Don’t know how far I’ll take this. It’s an interest today…maybe not tomorrow. Since I made progress converting EBCDIC data… “I found this which says simh can read the aws format. And since I already have some valid fake customer aws tape files from my Hercules work, it’s one less thing I have to do. …

Basic-Plus EBCDIC
Trying to rebuild a Basic-Plus EBCDIC table. Because we processed a lot of customer EBCDIC data on our ASCII PDP-11/70…back in the day. If not all then 99% of the customer data was in EBCDIC. But it’s a little different…I think. Because I believe the values were in DATA statements. And I already had a …
