I just received an HP 2647F terminal along with two 13272A 5.25" drives and cables plus a 02640-60043 modem cable and a 02640-60266 HPIB cable, but no manuals. Physically it all looks pretty good, no broken or missing keys and no screen burn or mold, and I figured out how to format floppies and create some files on them and the floppies seem to work ok. I figured out how to open the unit and looked at the boards inside and was slightly disappointed to find that the CPU is an 8085 instead of more cool 8080. This unit has a 1982 date. A couple of questions: I found some references on the web that the 2647A/F supports BASIC. Is that true? Is it in ROM, or does it need to be loaded from tape or disc? If it is in ROM I haven't been able to figure out how to get at it. Is the HPIB cable used just for connecting to printers, or can it be connected to other things? What's the difference between a 2647A and a 2647F? -Glen _________________________________________________________________ Broadband? Dial-up?

A Momentous Decision

by Robert_Feldman＠jdedwards.com

The only computer of mine that I named was/is my Otrona Attache 8:16, which I named "El Otorongo," (Quechua/Inkan for "The Jaguar"). Besides being alliterative, the name was appropriate, as this computer spent several years in Peru with archaeological projects I was involved with.

It taught the value of dry-running a program :-) When I worked at Edinburgh University in the mid-70's, our research unit had punch operators who'd punch the cards, and I'd take the boxes up the road about 3/4 mile and hand them in. Then they'd sit in a queue until the operator fed them in, and we'd get the printout back later that day (usually). I must have handled hundreds of thousands of punch cards, but now I all I have are three empty metal trays and one card (and I only have the card because someone sent it to me with a note on it a while ago). Can anyone remember how many IBM cards fit in a box? A card is nominally 8 thou thick, and a tray is about 16.5" long internally, so it must be something of the order of 2000. Who remembers drawing a cross or a diagonal line on the top of the card deck, so you had some chance of re-ordering the deck if someone dropped the box? Who remembers using a folded card (16 thou) to check the points on their engine (nominally 15 thou)? Folded in three to check the spark plug gap (nominally 25 thou)?? -- Pete Peter Turnbull Network Manager University of York

Apple //e and Mac parts

by dan＠ekoan.com

I was quickly corrected regarding the cables I mentioned earlier. They are DB-19 to 20-pin header (keyed), apparently an interface cable to the UniDisk drive. I also have several ribbon cables for the older style floppy drives. Also, I just located three Apple IIe emulation cards for the Mac LC series. These are just the cards, part number 820-0444-A. They're in anti-static bags but not sealed. Cheers, Dan http://www.decodesystems.com/wanted.html

Unibus on a VAX 6000 (was Re: New VAX 6000 toys.)

I am aware of an application that used a Unibus on a VAX 6520. The system would occasionally spontaneously crash; it looked to me like the UNIBUS adapter was getting wedged. Rumor has it they fixed it with a microcode upgrade to the DWBUA, but I doubt that microcode was ever made generally available. -- Roger Ivie ivie(a)cc.usu.edu

ASR-33 Line Feed Problems

by cmcnabb＠4mcnabb.net

I had this half-linefeed problem on my ASR-33 when I first rescued it >from the Barn. After a few nights of careful study (watching the mechanism at work) I decided that the spring on the ratchet device was stretched to the point of not being springy any more. I replaced it with another (from a carburater rebuild kit, as I recall) and it has worked fine ever since.

So the above command is equivalent to: MEM 60000:317,10 (the number of bytes is also in octal). So much for compatibility between the various Series 80 models. **vp

Heathkit H-8 Help

by clamrock＠nmtdie.com

Hi, I have a Heathkit H-8 of which I know nothing about. I am curious to play with this machine a bit but really I don't know where to start. I believe all I have for the H-8 is the computer - the part with the keypad & led display & a bunch of cables. What can I do with this? How can I test to see if it even works? Any ideas where I could go to find more information about it? Thanks all! Chris Lamrock

Osbourne 1 problems

by Robert_Feldman＠jdedwards.com

I have an O1 Tech Ref manual, from which I can send you info that might be useful. I'm busy this week, so won't be until next, though. One thing to check is the video shunt on the front of the unit. It takes the video signals and power from the bottom of the board and passes them to the top, where they go to the monitor. If the contacts on the shunt are oxidized, you could have video problems. The pinout of the edge connector is (numbered right to left, odd on top, even on bottom): (19 ... 1) (20 ... 2) 2 Ground 4 Brightness High ---> 3 on top 6 Brightness Low ---> 5 on top 8 Brightness Arm ---> 7 on top 10 Ground 12 Horiz Sync 14 +12 volts 16 Video Out 18 Vert Sync 20 Ground 3 and 7 go to the outsides of a 100K brightness pot, 5 to the wiper of the pot. Video out and one of the grounds go to a 500 ohm contrast pot. Bob -----Original Message----- From: Sark [mailto:ian_primus@yahoo.com] Sent: Monday, October 14, 2002 2:08 PM To: cctech(a)classiccmp.org Subject: Osbourne 1 problems I recently accquired an Osbourne 1 computer. I turned it on and it seemed to work, I was able to boot BASIC off of a floppy and I wrote a couple little programs, (print hello world, count to ten, and count forever, stuff like that). The picture on the screen was kinda dark in spots, and while the computer was counting, it flickered to a very dark and barely readable, then it went black all together. I tried turning up the brightness and contrast controls, the only one that makes any change on the screen is the brightness control. I can see the rasters when the brightness is up all the way, but the contrast control has no effect. The computer seems to still work though, I can turn it on, then hit enter and it will boot from the floppy. Previously, when it was working, I noticed the screen flicker when the computer accessed the floppy drive. My guess is that there is something wrong with the power supply. Does anyone have any ideas? I would really like to get my Osbourne working again, it's a really cool little computer. Thanks! Ian Primus ian_primus(a)yahoo.com
