Many years ago (March 2007 to be precise), I posted to this mailing list because I had typed in (by hand) the octal listing of TBX (Tiny BASIC Extended) from Dr Dobbs Vol. 1 No. 1, pp 16-17(
It turns out that this 8080 code basically worked and I was able to verify it in a Z-80 simulator.
Fast forward to 2025, and I have rediscovered this code and posted it to GitHub. I have also included an 8080 emulator in JavaScript so you can run TBX in your browser:
https://github.com/ericscharff/tinybasic
While keying in two pages of octal listings was an interesting exercise, I’m less keen to type in the source code for TBX, which appeared in Vol 1 No 2, pp 13-31.
I’d like to preserve this source code alongside the octal dump in my github repository.
Does anyone happen to have a listing of this source code in ASCII, or perhaps access to high quality OCR software that could perhaps automate the job?
The closest I can find is on Whipple’s own web site athttps://whippleway.com/Source_Code/TBX.asm
Which seems quite close, but is missing things from the first TBX (e.g., FOR / NXT loops)
Many thanks,

Way back when, I asked on the list about null modems for the DEC Pro which I
planned to use for experiments with SLIP. PRO/VENIX doesn't have any network
capability other than UUCP, and it doesn't seem like anything else supports the
Ethernet CTI card other than P/OS (of course) and the unofficial 2.9BSD, but I
like PRO/VENIX V2.0 better because it's a real System V.
Anyway, here's a simple implementation with four clients (ping, DNS, NTP and
command-reply TCP) which runs over the printer port at the standard 4800bps.
That keeps the main serial port free as a second terminal and for Kermit.
Getting it to work with both the PRO/VENIX Rev. 2.0 and V2.0 compilers (i.e.,
older-than-V7 and System V respectively) was interesting.
Unfortunately Xhomer's serial port emulation isn't good enough for this yet;
many dropped bytes. It works fine with my real DEC Pro 380.

The "RK11-D and RK11-E moving head disk drive controller manual" (EK-RK11D-MM-002) states in par. 2.5 (Installation Procedure) that the register and vector addresses of a RK11-D can be configured by "seven interrupt vector address jumpers and eight address selection jumpers of the M7257". The manual however doesn't state the address range that can be configured by these jumpers and refers to engineering drawing D-CS-M7257-0-1 for that information. I found these drawings in the RK11-D Engineering Drawings but cannot find information in them on the valid address ranges. Therefore my question: what is the address range a RK11 controller can be configured for?
Greetings,
Long story short, as the subject line says, I'm looking for some
VAX/VMS v4 era software. I've been working on putting together a
"turnkey" VMS v4.7 system — I've mentioned it over on the SIMH mailing
list once or twice, and if anyone is on the ClassicCMP Discord server,
Mainframe Enthusiasts Discord Server, or DEC Discord¹, you've likely
seen me mention it multiple times — and I'm currently trying to copies
of some of layered products.
To the crux of the issue, does anyone here have — as an image, or
media that they are are willing to image/have imaged — the
installation media for the following software for VAX/VMS v4.x?
• VAX NOTES
• VAX P.S.I.
• VAXset/DECset — specifically the Language Sensitive Editor
• CGRAF and CIMI
And just because I have a deep loathing for myself:
• Eunice
I'm also always open to any other software for VMS v4.x if anyone has
any they want to share.
Best regards,
Christian

G'day,
I have a ThornEMI Datatech 9800 9-track tape drive.
Has anyone a user- or service-manual or a description how to load a tape?
This drive can load the 7" 9-track tape reels and has an industrial interface with edge-connectors P1 and P2.
Thanks in advance
Lothar
