Odd stuff while cleaning up ...
by Neil Cherry 18 Feb '18

18 Feb '18

So today I decided to dispose of a ton of useless books. Like Java (1.1, 1.2, 1.3 ... ) and older C++. Anyway, like many of us I saved notes and print-outs in binders. A number of the binders contain class related things (Awk, Networking, etc.) all going but that's when things start getting interesting. I found an unopened box of 3.5 HD DS diskettes I found a ton of older software on 5.25 and 3.5 diskettes. Most likely Atari 5.25, the 3.5 HD are a bit of a mystery. It might be OS9. There should be some 360, 1.2 and 1.44 diskettes for MS DOS. I also have a I'll probably need help with that. I found my notes on the PT68K (Microware OSK), the Sardis ST2900 (Microware OS9), an original Omnimon manual (I think I have more than the Archive has). I found installation notes on installing Linux 0.92.. I'm pretty sure I have several Older SLS or Yggdrasill CDs. Finally I have some notes on the 7300/3B1. I'll bring the stuff on March 3rd. So if anyone wants a peek I'll share. I'll also try to get this stuff scanned. -- Linux Home Automation Neil Cherry ncherry(a)linuxha.com http://www.linuxha.com/ Main site http://linuxha.blogspot.com/ My HA Blog Author of: Linux Smart Homes For Dummies

GW-BASIC joystick programming
by Evan Koblentz 18 Feb '18

18 Feb '18

How do I program joystick input in GW-BASIC? It's insanely easy in Applesoft: you use the PDL(0) and PDL(1) commands to determine where the stick is located along X/Y (0-255 on each scale) and then tell it what do based on those locations. For example, in Applesoft, my Lego robot navigation code looks like this: 3000 REM NEVIGATION 3010 FB=PDL (1):LR=PDL (0) 3020 IF FB < 75 THEN M=5 3030 IF FB > 180 THEN M=10 3040 IF LR < 75 THEN M=9 3050 IF LR > 180 THEN M=6 3060 POKE L,M: REM SEND COMMANDS (The variable L is the address of the interface card to the control box. The variable M gets translated into binary to turn the relevant bits on/off at the control box, which runs the motors, sensors, and lights.) How do I do this in GW?

Can someone point me to a PDF of the Compaq Portable BASIC manual? (I believe it's IBM Advanced BASIC version 3.3, but I'd like to see the Compaq manual.)

Assistance Programming PROMs
by Henry S. Courbis 16 Feb '18

16 Feb '18

I have six units of Fairchild MB7052, 256 x 4bits PROMs. Thought my old Advin-MVP would program these, but seems it can't. Checked around and found they MUST be directly supported as other settings like National's 74S287 part won't work. Something about different voltages needed I believe. So... Anyone here have an IC programmer which can program these Fairchild MB7052, 256 x 4bits PROMs? Contact me off-list and let me know your address and any other details like payment. Thanks! Henry S.

Museum report
by Evan Koblentz 16 Feb '18

16 Feb '18

Adam and I worked in the museum and warehouse from 11am to 10pm today. We are tired, but we got good things accomplished! Some highlights: - Herb stopped by for two hours and helped us identify some unique items. - Roddy (artist across from VCF museum) helped us install the first part of a hallway display case. - We organized some Univac items - We cleared and put away a pallet full of random boxed items. - We built a shelving unit partially for Altos (not "Alto") computers and partially for analog stuff (Heathkit EC-1 and extra Philbrick items). - We built a shelving unit for more S-100 items (mostly Cromemco). So, with those last three points, we freed three pallets of space from the unorganized side of the warehouse and got their contents onto proper shelving racks in the organized side. There is still a lot to do (always!) but it's always rewarding when we leave the warehouse cleaner, better organized, and appearing emptier than when we arrived. We made some plans for how to proceed next time. There are more areas of low-hanging fruit where a little work will make a big difference.

Looking for “clean” Morrow code
by Richard Cini 16 Feb '18

16 Feb '18

All — I’m looking for a clean copy of the program “format mw.c” from the Morrow distribution disks (probably The versions on-line (the RLEE archive) seem to have garbage characters in them (maybe from a bad OCR)? Does anyone have this that they can send me? It’s a hard drive formatting program for the HDC_DMA controller. Thanks!Rich Get Outlook for iOS
