It actually underwent a boom in the later years, as Ethernet got cheap and diskless network devices became attractive. It is a simple lower level datagram protocol, and does not need the normal session stack to run. In smarter network devices, a MOP bootstrap can be in the device ROM. All that said; architecture, implementation, and deployment vary with platforms and time. For those that grew up on TCP/IP only (and thus doomed to repeat the past), it is best to think of MOP as the DECnet analog of BOOTP, with a little bit of DHCP and ARP sprinkled in. ... > 8.

I was a software engineer for DECnet-RSX, DECnet-PRO, DECnet-DOS, and PATHWorks. I was also the architect of the DAP Protocol v6 and a DECnet Token Ring Datalink. The later included MOP specfications too. I still have copies of all the Phase IV era DNA specs. Dave.

This could be solved by placing two 220pF ceramic capacitors over pins 7 and 11 of IC29 and IC37. This would fix the Beeb's booting problem, but unfortunately this would create a DRAM timing problem for Solidisk's 96k Sideways RAM expansion for the 32k SWR board. Took me (literally) years to figure that out! One of my 'when-i-have-time' things is experimenting with the capacitor's value to see if I can find the right value :-) Cheers, Eelco

DEC parts code reference?

by aek＠bitsavers.org

did DEC (or a third party) ever produce a reference listing of DEC "parts codes" against function (e.g. RK05 = removable disk, KL11 = serial interface etc.) -- Yes, the 'edited' and 'unedited' options/modules list(s) The April 1983 edited document can be found at http://bitsavers.org/pdf/dec/modules/modulesAndOptions/ There are separate catalogs for documentation, since they changed more often with software releases.

free for shipping: IMS 5000 IS system, from austin, tx, usa

by frustum＠pacbell.net

I have mentioned this system on this list a couple times before. The IMS 5000 IS is a S-100 based multiprocessor system running turbodos 1.3 (an extended multiprocessing CP/M clone). It is a very well built machine, clearly intended for office use. It has a single DSDD 96 tpi 5.25" floppy and a 10 MB hard disk (rodime ro 200). It boots off the hard drive, and couple months ago I spent some time and cracked the login/password file. The floppy disk appears to work (I can "dir" and get files off a floppy created on a PC using the teledisk program). The system doesn't have much on it in the way of development software, just some custom apps written for the dentist's office this came out of. As it is a CP/M system, though, you can use standard CP/M programs on it. The master system has a 8085-based intelligent terminal card, plus a master Z80 CPU and two slave Z80 CPUs. Each cpu has 64 KB of parity checked DRAM. I tried plugging in the slave to the master but I suspect things are not cabled right, as the slave terminal acts as if it is wired in parallel to the master terminal. I'd like to find a new home for this system. I simply don't have enough time to mess with it, and I don't have enough interest to make the time. Here are some a few cruddy pictures: http://home.pacbell.net/frustum/ims5000/ The only problem is that the local/remote key on the slave terminal keyboard is broken off (before I received it). The key still works; you can depress the stub of the plunger that is left, but luckily it is a key that normally doesn't need to be used. This system would be shipped from austin, tx 78737 at your expense. I recommend fedex ground, as it seems to be the least expensive of the majors for heavy items like this. It would be two boxes. I haven't weighed them, but I would guess 50 lbs and 30 lbs. They were shipped to me in their original boxes, and I'd ship them to you the same way. This means that there is a custom foam shell for each unit, but it also means that the original boxes are somewhat tattered and one has been reinforced, so don't wail that I've ruined everything by harming the original boxes. I'll give preference to anybody willing to come and pick them up, soon.

New DEC problem

by RodSmallwood＠mail.ediconsulting.co.uk

Hi Boot, well sort of. Its down loading a file from a boot server using BOOT EZA0 (The ethernet port). That it does OK and on the boot server it says download OK. However it does not run the downloaded file. I may have the wrong one.

When I had a KZQSA in a VAX 4000-500 I found that it would fail self-test if either port was left unterminated. I would not be surprised if an unterminated DSSI port had the same effect. Does it still boot if you make it boot manually (i.e. is the error fatal or does it just interfere with automatic booting?) Antonio

Re collection profile

by RodSmallwood＠mail.ediconsulting.co.uk

Well the DELNI can come off the list and from using a Chase IOLAN box as terminal server. I now have enough Decserver 200's to connect every type of serial device DEC ever made. They were going for a song so I gave them my version of "My Way" and got them very cheap!! Rod Smallwood
