> www.ebay.com/itm/260934669305 > Is this the motherboard for a Tek 401x? I think a 4014 is a 6 slot motherboard with a 6 slot extension and discrete connections on the short side not long side. Is a 4010 the same? It is vaguely reminiscent of many 70's era Tek backplanes... maybe this is for 0one of their early microprocessor systems?

vaxstation video compability question

by dgahling＠hotmail.com

I have a question about video compatibility with the vaxstation. the vaxstations I have (3100s M76) come with a funky cable to output to 3 BNC connectors -R, G, and B. I just picked up a Sony LMD-1410SC Monitor which has RGB BNC connectors (and others). I looked at the specs for the Sony, but not sure it will work. the link for the specs is here: http://www.aegis-elec.com/products/sony-LMD1410SC.html I'd really like to replace the ViewSonic P810 Monitor I've been using for this, even though the P810 is a nice 21" monitor, it's an old CRT, meaning it's huge and weighs a ton. btw the viewsonic is free (for the cost of shipping) to a good home if this works. anyone know? thanks, Dan.

PDP-11 Values from MFPT

by jhfinedp3k＠compsys.to

I have an interesting hardware question. I have been looking at the results for the program RESORC.SAV in RT-11 with respect the MFPT instruction. When the J11 chip is used, the value is 5 and the Maintenance Register at 177750 seems to determine what the rest of the actual hardware supports. I thought it would also be helpful for the user to know if an emulator is being used, either software or hardware, or if perhaps some other 3rd party hardware CPU. I would probably target the various 3rd party boards as far as hardware is concerned (such as QED and Mentec). For software emulators, I would suggest that only the high end PDP-11 processors be supported (the DEC CPUs which support the MFPT instruction) in order to keep things simple, at least initially. An incomplete list of software emulators is: SIMH Ersatz-11 An incomplete list of hardware boards is: QED - more than 1? Mentec - at least 3 and I can remember at least 2 others, but not the company names. Right now the Logical Co. has a combined emulator called a PDQ-1000 board which actually plugs into a Qbus which takes only 4 slots, but includes CPU, memory and many controllers. Thus far, the high order byte of the MFPT instruction always seems to be zero and is currently ignored by the RESORC.SAV program. Under SIMH and Ersatz-11, it would be trivial to use the high order byte of the MFPT instruction to signify which software emulator is being used. Can anyone who has a DEC (or non-DEC) PDP-11 system easily available determine the actual value returned by the MFPT instruction? As far as I know: MFPT Value Hardware 1 PDP-11/44 3 PDP-11/24 (should be 2) 3 PDP-11/23 4 SBC-11/21 5 All J11 chips including 11/73, 11/83, 11/93 I assume that it would be extremely difficult, probably not worth the effort, to modify the high order byte of the MFPT instruction at this point for the 3rd party PDP-11 CPU boards, such as from Mentec. Can anyone comment on this assumption? Might there be another way for hardware to the tell a user which 3rd party board is being used as a PDP-11? The other possibility is to use the Maintenance Register at 177750, although I suspect that there might not be any more bit available. Jerome Fine

Honeywell DDP-124 manuals...

by geneb＠deltasoft.com

I've got two copies of the Honeywell DDP-124 Instruction Manual Volume II (Timing/Flow Diagrams and Instruction Analyses) that need a new home. Hopefully someone can scan one or both of them. They're dated 1967 and the comb binding isn't faring so well after 44 or so years. They're an odd size - 11" x 15". The DDP-124 was the computer behind the Conductron-Missouri 737-200 and 727-100 flight simulators I used to work on. It ran the flight model & motion base. The visuals were provided by a Sperry machine (Vital II) for the 737 and a Varian 610 (Vital I) for the 727. g. -- Proud owner of F-15C 80-0007 http://www.f15sim.com - The only one of its kind. http://www.diy-cockpits.org/coll - Go Collimated or Go Home.
