PDP11GUI: a graphical diagnostic environment for PDP-11's

by j_hoppe＠t-online.de

Hi, I developed a graphical developement environment for PDP-11's. It's name is "PDP11GUI". Since it is spreading on the net already, I'm forced to announce it early. Status is "mostly beta". I begun building it in spring 2008 as a tool for my own 11/44 restauration project, but it quickly developed it's own momentum. Key features: - interfaces to 11/44 and SimH, ODT interface is under development. - interfaces through physical COM ports or via telnet. - visual display and manipulation of memory content - symbolic display and manipulation of I/O registers and bits. - can assemble and deposit MACRO-11 programs - can Run/Stop/Single step through code, displays execution position in source code and/or disassembly - can also be operated through photorealistic simulated PDP11/70 panel. - I/O page register scanner - Memory loader - 11/44 micro code display - MS Windows MDI application. - Free for non-commercial use. It is free for non-commercial use, download at http://www.j-hoppe.de/PDP-11/Resources/setup.exe Mandatory documentation at www.j-hoppe.de/pdp11gui.html Enjoy! Joerg Hoppe

Teletype Model 43 ribbons (and old ribbons in general...)

by derschjo＠msu.edu

Hey -- Stumbled across an old Teletype ksr-43 this weekend and couldn't pass it up. Seems to be working but the ribbon's (obviously) dried up. Was considering re-inking it but it's so worn through in places it's about to fall apart. Can't find anyplace on the 'net that still stocks them (lots of them /list/ it, though, which is annoying). Anyone have any leads? And while I'm on the subject -- anyone have any good leads for old typewriter ribbons? I have an old L.C. Smith Bros typewriter that's in need of one... Thanks as always (and still working on the Otrona Attache...), Josh

KMAX Kuma Atari Transputer Development System on Ebay

by a.financial.engineer＠gmail.com

Kurt et al, For those Atari fans (and transputer fans as well), I just posted a KMAX TDS for you lads. EXTREMELY RARE. Far more than the Atari Transputer Workstation which can be found once in a while... http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&Item=260304127531&Category=41… Good luck, more to come...

I looked at the site hoping to get a drive chassis, but that's > gone along with related to communication with Todd Fischer. I had heard something to this affect as well. Several people had placed orders and paid deposits and all went into a black hole. The word on the street was that he abandoned the idea but left the web site up. I sent him email about six months ago asking about one of his replacement part kits for the Imsai and never got a response back.

Transputer-based stuff on ebay

by a.financial.engineer＠gmail.com

In response to James regarding whether or not I will ship to UK. Yes, I will ship worldwide if: 1) Paypal is accepted 2) You pay for shipping of course... Note that there is going to be a HUGE lot of stuff that is going to be listed. There is just too many things and the we are moving. The wife is complaining too :-) I will of course keep some of the rarer transputer hardware, but majority of the other stuff is going. The books and documents I collected are massive and that will be the next to go up. I really hope someone in the newsgroup gets them as I really want these preserved and scanned (if possible)...

PET composite video adapter

by ethan.dicks＠usap.gov

Hi, All, I'm just finishing up assembling a PET "Video Mixer" from an old JPG of a much older scan of said circuit. This particular one is annotated as being from the "Commodore Pet Users Club of England - Newsletter issues 1 & 2, page 9". It's the variant with three NOR gates ('LS02), with a few resistors, capacitors, and a diode. The part that I'm curious about is how much variation is allowed in the caps. The schematic shows the horizontal sync coupled to a gate via a "2200 mf" non-polarized cap. I don't know that I have any disc or ceramic caps that large lying around. The output of that gate (which NORs the inverted vertical sync with the massaged horizontal sync) feeds unto a "47mf" tantalum cap (then pulled down to ground by a diode, and wire-ored to inverted video out/composite out via a 470 Ohm resistor). I have 47uF caps, but that seems pretty large to me. I have a basic understanding of RS-170-type video, and I know this circuit is probably going to produce a signal that "modern" IC-based video inputs will not like (much the same way the classic RCA CDP1861 video behaves), but fortunately, I have an old B&W security-type monitor to plug this into (which has already been tested with a CDP1861). I'm just curious why the caps are so large. I think I get what's going on with this circuit (the way it combines the syncs and video), and I've heard of similar circuits being used successfully by others, so with luck, it'll work the first time. Oh... in case anyone is wondering why I'm bothering, I have a couple of naked PET boards here, no chasses, no CBM monitors. I did cobble up a DC-based harness (+5, +12, -5V, no tape motor voltage, but then no tape drive, either) for testing, and I do get "interesting" looking pips on a 'scope when I check for video, so I'm hopeful that the boards are working well enough to at least give me a screen full of _something_, even if it's the classic "garbage" screen you get when the machine isn't running well enough to zero video RAM. So has anyone here made an external PET video adapter and have any experiences to share about what worked and what might not have worked? Thanks, -ethan P.S. - I found another type of composite circuit using a CD4011 as an inverter and a CD4066 to mix the signals, but for some reason I don't have all the components labelled on my drawing - the cap on hsync in particular. One interesting variation with that one is that the 'LS02 circuit has a 1.5K pulldown on hsync between the cap and the gate, while the CD4011/CD4066 circuit has a 10K pot. How much adjustment on hsync is likely to be needed between the PET and the first gate of the composite circuit? -- Ethan Dicks, A-333-S Current South Pole Weather at 13-Oct-2008 at 03:50 Z South Pole Station PSC 468 Box 400 Temp -54.4 F (-48.0 C) Windchill -76.4 F (-60.2 C) APO AP 96598 Wind 5.1 kts Grid 65 Barometer 671.7 mb (10943 ft) Ethan.Dicks at usap.gov http://penguincentral.com/penguincentral.html

Old Computer Quiz

by aliensrcooluk＠yahoo.co.uk

Here's a short (10 question) 'old computer quiz'. It'll probably only be up for a week or so, but should be in the quiz archives after that. Admittedly, the last 3 questions are rather modern, but fit within the 10 year rule (except possibly Q10). http://news.bbc.co.uk/1/hi/magazine/7671677.stm For the record I failed the 1st question which I know I should have got after the recent discussion on Space War. I scored 8 out of 10, though with some questions only having 2 answers it's a bit 50:50! Regards, Andrew B aliensrcooluk at yahoo.co.uk
