Hi, Just to keep everyone updated, I've received the corrected overlays. So any overlays that are now ordered will come with the correct overlays. Those who've received overlays previously will get replacements (free/no shipping). I also have 3 new overlays as well. An overlay for using the KM11 with an RX01 and a pair of overlays for the RK11-C. The website (www.shiresoft.com/products) has been updated to reflect the availability of the new overlays and the pricing. Thanks. -- TTFN - Guy

RainbowIDE 1.0 Available

by zmerch-cctalk＠30below.com

Ohmygosh - On-Topic Commercial Plug Follows! If you can't handle ontopic stuff, or commercial stuff, look away now! ;-) Anyway, I offered to put a post on the cctalk list for Roger Taylor to let people know that he's released a new Integrated Development Environment called RainbowIDE that allows you to create new, exciting programs for many different classic machines out there. If there's a cross-assembler that runs on Windows for that processor, and M.E.S.S. can emulate the machine, then this is the rascal for you. I haven't had a chance to test RainbowIDE yet, but I have used it's predecessor - Portal-9, which is great for coding for the Tandy CoCo and/or Vectrex machines which are 6809-based. It's slicker than oil on water.[1] This new IDE can handle 6502, 6800/6809, Z80 and other CPUs, and you can assemble your code, spark up M.E.S.S, mount your virtual floppies and/or ROMs, and test them all with a single mouseclick. Yes, this does run on Winders, but it's designed for coding new proggies for classic machines (mostly 8-bit, but there might be some 16-bitters possible as well)... go check 'er out. http://www.rainbowide.com/ Laterz, Roger "Merch" Merchberger [1] My affiliation with Roger Taylor are solely as a very satisfied customer, and we have the same first name. I'm *way* too ugly to be a "compensated endorser." ;-) -- Roger "Merch" Merchberger | A new truth in advertising slogan SysAdmin, Iceberg Computers | for MicroSoft: "We're not the oxy... zmerch at 30below.com | ...in oxymoron!"

earliest graphics display system in your collection?

What about mid-80's SGI? I have an '86 vintage system with 12x geometry engines and 32 bitplanes - granted it's not Skywriter/VGXT or Reality Engine, but compared with other graphics from the time it's pretty hot. I fear that it doesn't have a Z-buffer, though (not completely sure yet).

HP 87XM available in West Sussex, UK

by flo＠uk.thalesgroup.com

I've just pulled a working Hewlett-Packard 87XM out of some test equipment at work. It has the following bits with it: 82939A Opt. 001 Serial Interface 82936A ROM Drawer with 00087-15003 Rev. A I/O ROM 82909A 128K Memory Module 82901M Flexible Disc Drive (2 x 5?" drives) No manuals, no software. Take the whole thing, pick-up only from Crawley. I don't care about timescales.

RL02 problem

by henk.gooijen＠oce.com

Boot the system to RT11 and put the cartridge that will not boot in the second drive (assuming DL1:). Do a .DIR RT11* You will see RT11FB.SYS, RT11SJ.SYS and probably RT11XM.SYS. They are the monitors. Choose the one you want and do .COPY/SYS DL1:RT11FB.SYS . (exactly like this, the final dot belows to the comnmand). That will write the monitor to the boot block(s). - Henk. > -----Original Message----- > From: cctalk-bounces at classiccmp.org > [mailto:cctalk-bounces at classiccmp.org] On Behalf Of Ethan Dicks > Sent: donderdag 20 april 2006 7:39 > To: General Discussion: On-Topic and Off-Topic Posts > Subject: Re: RL02 problem > > On 4/20/06, Jim Beacon <jim at g1jbg.co.uk> wrote: > > After rebuilding the machine back into its new box, it all > worked.

IBM Bus & Tag channel protocol specs?

by brian＠quarterbyte.com

Hi Patrick, This is a pet project of mine too. Let's talk. I have done some work on this & would like to see it move forward. Having someone to work with would be great. The spec is called the I/O Interface Channel to Control Unit Original Equipment Manufacturer's Information (OEMI) and it's available online for free and in hardcopy for a nominal fee >from IBM. Search for document GA22-6974 at www.elink.ibmlink.ibm.com/public/applications/publications/cgibin/pbi. cgi?CTY=US Also, there is a yahoo group for people interested in hanging hardware on Hercules, called ibm-legacy-hercules Brian =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- _| _| _| Brian Knittel _| _| _| Quarterbyte Systems, Inc. _| _| _| Tel: 1-510-559-7930 _| _| _| Fax: 1-510-525-6889 _| _| _| Email: brian at quarterbyte.com _| _| _| http://www.quarterbyte.com

RL02 problem

by jim＠g1jbg.co.uk

Hi, last week, my PDP11/23+ was rebuilt into a new chassis (went from OEM 19" box to a proper 11/23+ chassis), and after the rebuild failed to work :( My first suspect was the new chassis, so it went back into the old box - still no boot. After trying each of the RL02s in turn, and even a different controller, I still couldn't get the machine to boot. After a little head scratching, I tried an alternate disk pack (still RT11), and the machine booted. After rebuilding the machine back into its new box, it all worked. A little more investigation shows that I can still read the faulty pack (installed in the second drive), but that the boot information is either corrupt or gone. Now for the question: can I restore the boot information, or will I have to re-initialise the pack and start again? (not a problem - it was my games pack with the extended monitor, but I can restore it from a backup, if needed). I will take all of the comments of "idiot" with good grace....... Thanks Jim.

Just not in the way we > might expect. ;-) Congratulations to getting this thing back into functional state. I wish you a good time and many years of satisfying operation for your device. Incidentally, I've been having a bit of fun with a MEINBERG GPS166 Satellite Controlled Clock lately - it had been set aside as defective at the computing center of Erlangen University and I happened to get it for the asking, together with its bullet-shaped "radome" antenna/amplifier. When I finally built myself a coaxial cable to connect the two (SMA <-> N-Type), I had a working setup! But after a relocation a bit later, I got some smelly smoke and an "antenna fault" error when I powered it on. Turned out to be a small cylindrical choke in the shielded RF box which had gone open circuit - possibly involved with supplying power to the antenna amplifier. I checked the coaxial cable for shorts, couldn't find one at that time, replaced the choke and had the next one burn through. I disassembled and reassembled the N connector very carefully, replaced the choke once again and have been operating the clock without problems since then. It too can give out fixed and adjustable frequency pulses - along with second and minute signals, which you could amplify adequately to drive daughter clocks like that falling-leaf wall clock I have (needs a 24V pulse every minute). The special plus of the unit I have is the so-called "Erlangener Firmware" which was custom-written for Erlangen University. The usual variety only used the serial port for giving the time - either in intervals, when a ? was entered or when a pulse occurred on a logic input - but this one also puts out the geographical location, so one could even use it for a navigation system, in theory at least.

there is hope for tiny code!

The books benefit from being able to convey far more than either the radio or TV versions. The TV version is very much a victim of it's format. > I've not bothered to waste my time on the movie. It is worth a look and could have been much much worse. There is even a cameo appearance by the Marvin from the TV series. The biggest disappointment for me was that the Vogon ships weren't yellow and they didn't just hang in the air in exactly the same way that bricks don't. Lee.

There was a CV thread on here not too long ago The later ones weren't so pretty - goodness gracious great hunks o'beige, and Sun based. For a while, I think Novas were the "in" machine at CV.
