Foxboro PCP-88 (PDP-8)

by foo＠siconic.com

According to this FAQ: http://www.faqs.org/faqs/dec-faq/pdp8-models/section-2.html ...the PDP-8 was OEM'd to a company called Foxboro Corporation that re-badged it as the PCP-88. Has anyone ever seen a PCP-88? I would assume it is functionally and physically equivalent to a DEC PDP-8?

Foxboro PCP-88 (PDP-8)

by xds_sigma7＠hotmail.com

Hmm... core and and a single-chip 12-bit microprocessor sounds pretty unlikely.. Plus, I'm fairly sure Fabritek made its own computers at one point in time, and I doubt they were clones of anything.. Then again, I can't say I've ever found any actual info on them, either.

What's the best way to slurp up DEC RX50s?

Motorola zc93124cp

I think that's out of the question, since it's embedded deep in another non-computer-related thing that hasn't been made since the late 80's. > This is why it's much more interesting to deal with OLD computers. I agree, but my aim is to either re-program this thing, or replace the embedded computer completely with something that does work in a well documented way. It will require interpreting some (simple, open/closed and possibly some "timed pulse" kind of things) signals from other equipment, interpreting the signals, and displaying the results on a pair of matrix displays. One is possibly twenty-something by twenty-something, the other 8 or so by maybe 64. Of course, I've also thought about replacing the matrix screens with an LCD of higher resolution. The thing is, I'd rather see about just writing new code for it, but to do that, I need to figure out just what I'm looking at. Another related question is, assuming that this were an embedded ASIC from that era, what could I hope to find inside? Might it have its own internal PROM to store the program? (In which case, I'd need to find a replacement, or use a different chip...)

One SCSI tape connected to 2 hosts?

by bob_lafleur＠technologist.com

I've noticed that my MV3100's SCSI host ID's are set to 6 - I thought this odd, as host ID's are usually 7. Are all MV3100's set to 6, or is mine unique? Anyway, I thought since my PC's host ID is 7, I could connect my SCSI tape drive to both systems. So I ran a cable from one connector on the back to my PC, and a cable from the other connector to my MV3100. I figure it's a properly terminated chain, as each host controller is terminated (I know the PC is, I assume the MV3100 is). It *seems* to work OK. But can anyone tell me for sure if this is "legal"? I'm sure I'm looking for trouble if I try to use the same tape drive from both systems at the same time, but as long as I don't do that, is this an okay setup? It would sure beat changing cables every time I want to move the tape drive from one system to the other. - Bob

RT11 & RSX cd images - additional site

by jwest＠classiccmp.org

I noticed that downloads of the ISO images for RT11 & RSX freeware from Tim Shoppa's website are slowwwwwwwww. I'm not sure if he has a really slow internet connection, or if he (or his ISP) is throttling bandwidth (I suspect the latter). To provide for faster downloads to anyone who wants it, I am copying the RT11 & RSX freeware ISO cd images to www.classiccmp.org/PDP11 They should be up there sometime tomorrow morning, don't download them from me before then or you're likely to get a partial image. And you can bet you'll get more than 14kbps from my servers :) Also, if you only want portions of the freeware CD's rather than the entire ISO image, the entire contents are already at that URL in natural (non-ISO) form to download individually.

new toy DG Nova 4X

by rigdonj＠cfl.rr.com

I went by a surplus place today and found the remains of a DG Nova 4x that they'd already scrapped. Further searching revealed a 4x that they hadn't gotten to yet. I grabbed it, the floppy drives (8") from both units and the front panels from both and the CPU and a couple of other cards from the first unit. I did leave behind the hard drives (that may have been a mistake). Does anyone have info on these? Joe

Warner /Amex "QUBE" set top box

by truthanl＠oclc.org

I think Bank-One and OCLC also had some research resources commited to the early interactive cable project. I recall we used to have some proto-types of set top boxes with an interactive cable banking function somewhere in the penthouse. Mid to late 70's - I think we trashed 'em. Some of the upper management was interested in interactive communicatoin >from homes - but it became obvious that it was difficult to incorporate with our library based mission. So our research was based on cable broadband network technology study - but I remember we had proto-type boxes - which also had a banking sponsor. Larry Truthan - Digest Subscriber

Cool IIgs find

by jrkeys＠concentric.net

At local thrift last night I got a Apple IIgs that had a ELINA fan and 20 meg harddrive combo mounted were the normal power supply goes. Also inside was a AE TRANSWARP GS card, AE VULCAN controller card for the HD, and a AE RAMKEEPER card with 2 Apple ram cards mounted to it. There was a dryfit A200 ext battery Sonnenscheen with it also that works with the Ram card? The cables, mouse, and keyboard also came with it and all or $12.21. I will have to go down to the shop and get a monitor to test it with. At the Goodwill I got a Radio Shack Electronic TV Scoreboard in the box without manuals:-( At another thrift I got a Genesis 32X unit for $3.93, Actimate Arthur by Microsoft, A new unopened package from Teledyne with a early Data Processing Symbols Template. There several other goodies but they are too new to list.

RS/6000 7013-580 troubles

by pat＠purdueriots.com

I know this is just under the 10yr rule, but it's pretty close, so please bear with me... OK, I've got the SCSI drives from the 55L mounted in the case, hooked up a terminal *and* keyboard, and this is what the LED display shows: 120 124 400 When 400 is displayed, the led next to the power switch goes off, the rs-232 port no longer has output voltage, and the machine just sits there. No playing with the reset button or smashing of keys on the keyboard or terminal will wake it up. Anyone have any ideas? The config is: 2-1 Ethernet card 1-9 Video card 4-4 Single-ended scsi-2 card 128MB RAM CDROM drive floppy drive 2x2GB hard drives (3.5" HH) which seemed to at least spin up in the 55L. -- Pat

how to preserve old RL01 pack data?

by healyzh＠aracnet.com

> The question is, how can I get a copy of a pack as a > binary image onto the PC ? (to load in simh for example ?) I don't suppose you have access to a MicroVAX? I always do this under VMS, and then FTP the data over to a UNIX system. Unfortuantly I'm not sure how you can do this under RT-11, however, I'd guess that at a minimum you'd need a RL02 drive and pack to hold the image for transfer over the the PC. Zane

That can be disabled by the application. Disabling PrtSc would require hooking the OS on every machine running notes. But if somehow they were able to do even that, a program like VMware running notes would do a nice job of making a screen capture possible.

[CCTECH] HP C19 calculator - power requirements?

by msspcva＠yahoo.com

Hello: Can someone tell me or point me towards a site with information on the power requirements for a HP C19 printing calculator? I've got one which I'd like to sell, but I'd like to see if it works or not first. It appears to be in decent shape, tho the carrying case is getting ratty. I see on the back it says "5V" and "1W", but the connector (I assume for a AC adapter) isn't labeled, and it has no power pack.

A VAX 6610 is rolling toward my garage ...

by gunther＠aurora.regenstrief.org

Hehe, there goes the last VAX out of my workplace, and right into my garage. And its a 6610! That means I will need to add in a few processors, but there is my NVAX. Much work is before me. I should get Ultrix 4.2 ported to it starting with the 6000-400 files. It can't be so hard after the 6000-500 runs... We'll see. Does anyone have the processor internal registers for the KA66A? With some luck we can drop in just a very small set of kernel files that can be reused under Ultrix 4.5 binary. For NetBSD it will be a little harder to replicate all the missing stuff. I think I will want to set up a fast cross compiling or native VAX box for that first. That also means that a 6400 will become free on relatively short notice. This one goes to Micheal McCabe, if he wants it (?) I am a bit reluctant yet to convert the 6400 to a -600 so quickly after I barely set it up. I guess I will take some time to actually do the conversion. But in a matter of 4 weeks after I took her home, I should probably get rid of that extraneous then 64x0 cabinet. (the 'x' depends a little on how I will distribute all the CPUs.) Also, there are the XMI and VAXBI backplanes (with some defect, but certainly not everything on both of them) free for the taking. They aren't claimed yet and that means I will decompose those shortly. cheers, -Gunther -- Gunther Schadow, M.D., Ph.D. gschadow(a)regenstrief.org Medical Information Scientist Regenstrief Institute for Health Care Adjunct Assistant Professor Indiana University School of Medicine tel:1(317)630-7960 http://aurora.regenstrief.org
