Never said it was never done. I said *most* didnt'. I have a triad of Visual 1050s that have a 6502+32k for graphics so I know some did. It was however quite rare for those to have a mouse and software that was mouse aware. Allison

D'oh! Backup issue solved

by kyrrin＠bluefeathertech.com

<arrgh> Sometimes, the best answers are the most obvious. You may remember that, not long ago, I posted a blurb about having trouble backing up an old MFM drive in a 1990-vintage datascope. Specifically, that it's non-DOS format and on a proprietary controller. As I was copying the manuals for a different datascope this afternoon, the answer hit me like a lightning bolt, prompted by noticing that the pages I was copying at the time had to do with backing up the hard drive in a Digilog unit. "Maybe" I mused "the Interview 7500 has the same capability." Well, guess what? It did! It was not obvious because it was labeled "Copy Disk" instead of "Backup hard drive," but it most definitely allowed selecting the hard drive as the source and the floppy as the destination. Three 1.44 meg floppies later, I not only had a backup copy of the datascope's OS, but I also had it archived with Teledisk into long-term storage. The moral of the story is: If you run into a hard-drive operated datascope, or any other special device that has its own drive, never assume that said device has no backup routine of its very own! ;-) -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- Bruce Lane, Owner and head honcho, Blue Feather Technologies http://www.bluefeathertech.com // E-mail: kyrrin(a)bluefeathertech.com Amateur Radio: WD6EOS since Dec.

Attn: Hams! Need help with CW/RTTY software for C64 or Apple II

by nerdware＠laidbak.com

Hi, gang. Over the weekend, I picked up an old audio-to-TTL or RS-232 interface at a hamfest (AEA CP-1, for those of you who know what it is....) with joystick-port TTL cable, but no RS-232 components installed. (That might be a project for later, since I have the book/schemo/parts list). I want to use either one of my C-64's or one of my IIe's with the interface, but I lack the necessary software. Since we all love old software, and I know several of us are hams, I figured this would be as good a place as any to start looking. If I can't find anything, I'll try installing the RS-232 components to the motherboard and see if I can get a regular serial port to work and try it on my pc. But I'd really rather use the older machines for this. CW receive/decode is a priority, since I can still send with a paddle, and I'd like to try decoding some RTTY if possible. Can anyone help? Thanks. Paul Braun WD9GCO Cygnus Productions nerdware_nospam(a)laidbak.com

Semi-OT: Soldering Iron recommendations

by ajp166＠bellatlantic.net

I'm still running a wTCP60, with ground. It's the one I bought back in '79 I think. I have two the other one is older and worn but it did build the Altair, and can vote and drink in all states!

VAX/VMS V5.5-2 Memory Requirements

RQDX isn't slow just that MFM drives runs at the same data rate as eithernet which is not fast. SCSI if you have it is faster, ESDI then MFM. Two RQDX3s running two drives is MUCH faster than one RQDX3 running two spindles(err drives).

VCF Requests i.e. liquid and solid fuel

by mmcfadden＠cmh.edu

I vote for greasy burgers and Pepsi I seem to remember writing lots of code and punching lots of cards late at night or early in the morning fueled by a couple of 2 liter bottle of Pepsi and many Jack-in-the-Box burgers. The only problem was when I finally went to bed I was unable to sleep and ran/walked through my code several more times. My father, the doctor, finally diagnosed the problem as way too much sugar and caffeine. I have heard that 1 or 2 dozen White Castle burgers is another substitute. Now 20 years later I've given up the Pepsi to prevent the ulcer. Mike Old Code Dog

Nuclear Data Cards

by xds_sigma7＠hotmail.com

Umm the only nuclear data cards I've seen date to the late 60's and there is no way in hell they would ever go in an LSI-11... I've wondered if the ones I've seen are from their clone of the PDP-8 but I dunno, guess they'll just stay the scrapper (the ones I know of that is).

Article copy - PE November 1981

by RCini＠congressfinancial.com

Does anyone have this issue of Popular Electronics? I'm looking for Part 3 of a series by Randy Carlstrom titled "Designing with the 8080 Microprocessor". Parts 1 and 2 appeared in the 9/81 and 10/81 issues of PE, respectively. If someone can scan this for me, I'd be most greatful. Contact me at home (rcini(a)msn.com) Thanks again.
