The only difference is that I know of was that the threshold for data was a slightly different voltage. The 8702A was designed to tie directly to a 8080 or 8085 without additional buffering. Otherwise, the 1702A spec will work. If y9ou want the exact levels, I can look it up. Most current programmers do not support the 1702A's. You'll need to find an old programmer someplace. Dwight

Request for help with a PDP 11/73

by chu＠verizon.net

UPS has already come by and they agreed to process a claim. My options are to get my money back and give them the machine or to get it fixed and they pay for the repairs or replacement -- up to my costs. I don't think replacement is very possible. The UPS guy suggested that I go to circuit city or Best Buy and buy the replacement parts.... Uhhhhh.....

Compact Flash (CF) cards

by Robert_Feldman＠jdedwards.com

You may have run out of interrupts for the CF card -- it requires two, one for the drive interface and one for the card, IIRC. On a laptop I had at work, I had to disable the modem (which I seldom used) in order to free up a second interrupt so I could read PCMCIA flash RAM cards that I used in my HP 95LX palmtop. -----Original Message----- From: gil smith [mailto:gil@vauxelectronics.com] Sent: Tuesday, February 04, 2003 4:28 PM To: cctalk(a)classiccmp.org Subject: OT: Compact Flash (CF) cards <snip> I got a couple of Compact Flash (CF) cards to play with, and I also got a CF-PCMCIA adapter to try the cards in my laptop.

Selectric Typewriter conversions

by marvin＠rain.org

Does anyone remember what was required to convert an IBM Selectric Typewriter to a computer printer? I seem to recall a kit of some sort was available, but my memory is *really* hazy about that.

New to list

by ssj152＠charter.net

Hi, I am new here; I've been lurking (reading the archives) for a while, decided to join. Since I retired I've taken up "retrocomputing" and see a lot of discussion here about systems I'm interested in and hopefully I'll be able to contribute at times. I am certainly having fun reading the posts - the recent posts about "middle posting" really cracked me up! I am interested in 6502 based systems, especially the KIM-1 and SYM-1. I currently have a VIM-1 and a SYM-1, having years ago been thickheaded enough to sell my KIM-1. Wish I had one now, can't afford one on eBay. I have nothing against the AIM-65, I just have never fooled with one and haven't been able to pick one up yet. My interest in small 6502's has been extended to small "trainers" with different CPU's, like the Heathkit ET-3400 and the HP 5036A. One of these days I may get around to fooling around with PIC's, but I'm still having too much fun with the old stuff. I'm looking for a copy of the HP book "Practical Microprocessors, HP part number 05036-90003" if anyone has an affordable source for one. I have inquiries out to several "manual" sites and am awaiting replies. I also have history with PDP-11's, using RT-11 and RSX-11M. I have a PDT-11/150 at the present and run RT-11 on it. What I'd really like to have is a H-11 (yeah, I can really afford that...no way) or better yet, a DCT-11 trainer. I saw 3 of the DCT-11's go by this fall on eBay and wasn't in a position to bid. In recent years I worked with VAXes and have several VAXStations and MicroVAXes, in the 3100 and 4000 series. I'm not sure these qualify as classic (3100-10e, 4000-VLC, 4000-60, 4000-90). I also have a few Alpha's. - Multia, AlphaStation 200 4/100, and AlphaServer 1000A. I spent the last 10 years of my career as a systems programmer working with OpenVMS in a process control (SCADA) environment. I am not so much a collector as a user and builder of computers and peripherals. By that I mean I'm not trying to corner the market, open a museum, or that I consider these computers as "investments". I am not likely to sell anything, but might be interested in buying a few things, especially documentation for some of the machines I have. What documentation I have I may at some time convert to PDF and publish for anyone else interested to play with. Stuart Johnson ssj152 AT charter DOT net

OT: Compact Flash (CF) cards

by gil＠vauxelectronics.com

Hi folks: This is off-topic, (and if you are in the sbc6120 group you have already seen it): I got a couple of Compact Flash (CF) cards to play with, and I also got a CF-PCMCIA adapter to try the cards in my laptop. Unfortunately, I cannot get Win-frickin-98 to see the card. I have a similar Smartmedia-PCMCIA adapter for camera cards, and it seems to work fine in the same machine (ibm thinkpad 600e). In both cases, I inserted the card/adapter, WinBlows sees it and starts the device wizard to install a "Standard IDE/ESDI Hard Disk Controller." For the Smartmedia card/adapter, the card automatically appears as a drive in Explorer, and all is well. For the CF card/adapter, it asked me to reboot, and even then does not see the card. The Device Manager Status for the controller says "device not present, not working properly, or does not have all drivers installed (code 10)." There are no resource conflicts to correct. However, the controller driver is seen by the PCMCIA utility that allows me to stop the card for removal. I've searched at ibm and microsoft, and various google finds, but cannot make sense of this, and have already spent way too much time on it. Has anyone had problems or success reading CF cards in Win98 with a PCMCIA adapter? Is a usb adapter a better choice? Upgrading the o/s is not an option, since I never intend to give microsoft another penny. thanks in advance, gil ;----------------------------------------------------------- ; vaux electronics, inc. 480-354-5556 ; http://www.vauxelectronics.com (fax: 480-354-5558) ;-----------------------------------------------------------

PeeCee obtained 5000AT

by jwest＠classiccmp.org

Recently obtained a *BLUSH* old PC. Normally wouldn't post about it here but... someone may be interested in a copy of the software on it. This thing is kind of a slimline desktop case, has a 3.5 floppy and 5.25 floppy. It's a leading edge model 5000AT. I think it is a 286. But what might be interesting to some is, it comes with something called "windos" I believe, and is a leading edge specific "make the computer simple" GUI sort of. Basically just lets you point and click to call 123, easywriter, etc. I thought someone might be interested in the software & gui files. God I feel dirty now *G*

Thats what I was hoping. I think that it is trying to boot from the disk that I think is dead. I have a vt420 to hook up, but I do not have the cabling that I need. I just bought a gender changer and a null modem on eBay. When they get here I will hook it up to see what the console output says.

Is there such a thing as a ZIF socket for PLCC chips?

by erd_6502＠yahoo.com

I am needing to burn PLCC-packaged chips in my DIP programmer. I expect I need to locate a PLCC<->DIP adapter of the right size (for 29C010 and 28F101 Flash chips, at the moment). Thinking about it made me wonder if any of the sockets were ZIF or LIF. Any ideas? Any recommendation on a source for adapters? Thanks, -ethan
