Dear Brad, I remembered my old program ASDAT. What is ASDAT? It is a DOS tool for capturing and examining captures for capturing and examining data communication on RS232 line. It works on any DOS computer which has 2 serial ports. Using special probe (two 25-pin CANON male/female connectors + two cables connecting probe to serial ports) it captures data + modem signals including exact time information (resolution is 0.05ms). The speed of communication can be up to 19200Bd. Data are stored in the buffer (size is 8kB characters). Data can be saved to disk file after capturing. Data are showed during capture and can be examined after capture ends. There is also possibility of triggering - if you are looking for some special sequence of data on communication line. There is also way to export data from captured file (both directions together or separately). If you are interested in ASDAT I can send you a demo (i.e. ASDAT without ability to capture + some captured files) to try the user interface. I can send you also full version free of charge if you are able to make the probe yourself (BTW 15 years ago ASDAT was being sold for about 5000 CZK - about 250 USD). There was also some other development in ASDAT (new version was written for 32-bit DOS environment): - bigger (nearly unlimited) data buffer - baud rate up to 115200Bd - continuous data capturing to file etc. As far as I can remember the new version was finished but never distributed. ASDAT was never moved to Windows. Regards Cestmir Lengal ClassiCAD, Zlin Czech Republic cleng at classicad.cz

HP 2116 on ebay

by jwest＠classiccmp.org

This is a classic HP currently on Ebay, a decent 2116C model. Item is 290099957210 What is so special about it, besides the obvious? Seller updated the auction listing with a card list. It appears to have two of the (rare) 12920/21 mux sets (32 ports), something that is required for all versions of TSB. I'd be willing to trade a nice mux panel for them in exchange for one of the two mux sets ;) Jay

The DN10k was a SMP-capable machine, so it is likely that (unless yours is SMP) there will be some extra XBus slots. DN300 was another Apollo oddity- bitslice CPU that (if I was informed correctly) emulates a 68030, and was done to "fill the gap" until Motorola had shipping parts.

HP 2116 on ebay

by MGemeny＠pgcps.org

Making sense of the history of this processor was what started me on quite a research project today. It really looks like it became the IOP when the system was upgraded to F and if it was part of the system at retirement, that system was never upgraded to Access. It could have originally been a TSB A, but perhaps more likely started as the Main processor of a TSB B. It could have started life as the main of a C but more likely an A or B than a C. I just seems to me to be too big to have started as an A, and too old to have started as a C. If it were to have been a TSB B Main processor, it would not make much sense to purchase a newer processor to upgrade the system to a C (I don?t think C needed the floating point instructions). But then an upgrade from B, C or C? to F would have purchased a new CPU for use as the main (because F needed the floating point micro-code in the main), repurposed the old main to become the new IOP, and retired the old IOP. An upgrade to Access would have retired this processor before the system was retired and the IO cards would have been repurposed in yet another new processor (Access needed both floating point micro-code in the main and IOP micro-code in the IOP.) So, it ended it?s life as an IOP of a C? or F (most likely F). It started it?s life as an A or the Main of a B or C (most likely the Main of a B). All just my best guess from a day?s research. YMMV If anyone is going to ask the seller a question, it would be cool to find out where the system was once installed. Thanks. Hope this helps, Mike Gemeny

Converting .TD0 to .IMD / new utility

by dave06a＠dunfield.com

I've been converting some of the .TD0 image files that various people have sent to me into .IMD format using the tried and true "write it to a disk with Teledisk, and read it back in with Imagedisk" technique. This works, but gets tedious as you need to keep starting/exiting Teledisk and ImageDisk, remember which file you are working on over the time it takes to read/write the disk, and worst of all, write down the comment record from the Teledisk screen and manually enter it into ImageDisk when creating the disk. Got tiring rather quickly... So I wrote a new utility which might be handy to anyone else wishing to convert images: TD2IMD automates much of the process of converting Teledisk .TD0 images into Imagedisk .IMD format. It builds a list of all .TD0 files specified (you can use '*' so "TD2IMD *" does all .TD0 files in the current directory), then launches Teledisk and Imagedisk in turn allowng you to write/read the disk. With a single keystroke TD2IMD will enter the filename into Teledisk, then capture the comment record displayed on the screen and place it in an empty .IMD file of the same name. After you finish with Teledisk, it automatically launches Imagedisk, and also with a single-keystroke enters the filename. Imagedisk reads the comment from the empty .IMD file, lets you edit it if you wish, then reads the disk into the file. Goes MUCH faster! TD2IMD is available on my site, go to the software page, then pick "Teledisk", and look for TD2IMD on the subpage.

looking for VMS installation CDROM

by vax9000＠gmail.com

Well, I do not want to boot the installed system; I only want the process of installing. I guess I do not need a hobbyst license for this purpose. If so, would somebody sell me his un-used VMS CDROM? Any version is file. Price should be less than the official copy. Please contact me. Thank you! vax, 9000

Converting .TD0 to .IMD / yet another new utility

IMI disk drive on Cromemco

by dm561＠torfree.net

------------------Original Message Date: Sat, 31 Mar 2007 21:02:51 -0400 From: info <info at harrells.net> Subject: IMI disk drive on Cromemco I have a Cromemco system that came with a IMI model 7700 Hard Drive. The drive was working when I got it but was having read errors. I begun backup up the files and planned on reformatting. I was able to back up the files I need but head a thump like something hit the drive of the drive. This is a 10" 5 meg drive with a plastic clear top. The drive then began to fail so I power it off and looked around as much as I could through the top. I power it back up and now the drive will begun ready. The heads look like they never go through the headload process but I can't be sure. If I move the unit I can see that the head actuator lets the heads float freely in and out.. I have measured all the power supply voltages going to the drive and they are good. I don't think it was a head crash as I don't see signs on the platters as much as I can see through the plastic. The top does look like it can be remove but I don't have a clean room I'm holding off until that is the last resort. I worked on CDC drives so this looks like one only smaller and without the little brush that would sweep the drives before the heads loaded. I don't have a manual so I'm limited to what I can do. I have a few questions if anyone can help with. The head lock does disengage when power is applied. Does the drive need to come up to speed before voltage is applied to the actuator? Does anyone know where I can find more out on this drive Should I get ready to make two wall clocks out of the platters? ----------------Reply: I think Herb Johnson will be able to supply you with a service manual: http://retrotechnology.com/herbs_stuff/d_crom.html (7710 IMI 7700 hard disk, 023-6027, January 1982, 100 pp.) I have one of these drives but it hasn't been powered up for at least 20 years, so I doubt that it's still good; they weren't too reliable even then. There was also a 7720 (22MB) version of this drive; they were superseded by the 5000 (5"FH) IMI drives before Cromemco finally went to ST-506. I also have the 7000 installation manual, but it only covers connectors, switches and schematics for the power supply. Get ready to make those clocks, but check it out a little more first... Good luck! mike
