IBM PCAM info needed

by bmachacek＠pcisys.net

Hi, I am applying to the VA for disability benefits based on a hearing problem that occurred while I was in the Air Force (early '60s). I worked in a very noisy PCAM room with lots of IBM 407s, repro punched card machines, and sorters. I have been trying to find articles or people who can verify these machines were sufficiently noisy to cause hearing problems. The VA turned down my first basic request, so now I need more details in just how loud these machines were. I know we have quite a few "old timers" on this board and I'm hoping someone can help me find the information I'm looking for. Let me know offline the names of any books, magazines or people that I may look for or contact concerning this issue or if you know of any websites that may contain this information. This note may not be quite "on topic", but I've run out of places to look for this information. Any help will be greatly appreciated. Thanks.... Bill Machacek Colo. Springs, CO bmachacek at pcisys.net

pdp11 bus - how long can it go?

by jack.rubin＠ameritech.net

As I slowly dig into "my" new 11/34A, I'm amazed by the bus configuration. Starting from the CPU, the main BA11 chassis has a double (9-slot) system unit, joined to a single (4-slot) SU by an?M9202 jumper. From the last slot in the chassis, a Unibus cable runs to a junction block on the cabinet back door. A second cable runs from there to a remote BA11, also with 2 SUs. A third cable runs back to the rack door/junction block (labled "bus station", BTW) and finally a fourth cable runs to a small rack mounted I/O box with a single SU and?an M9302 terminator in the last slot. Cable runs must be about 20-25 feet total. At first, I was worried that the length was too long (though it was a working system in use for several years) but after a quick websearch (www.psych.usyd.edu/pdp-11/unibus.html), I see that the bus can be up to FIFTY FEET before a repeater is needed. My short term plan is to pull all the cables and move the 9302 into the system box for testing. Now I'm worried that the bus might be too short - do I need to look for one of the "new" jumpers with two feet of cable or should it work with my old M9202 jumper block? Jack

Classic Epson printer emulators

by roger.holmes＠microspot.co.uk

I haven't seen one but its not difficult to write one for yourself. I had one for H.P. RTL which we used for testing our large format printer drivers a few years ago. I think I still have an Epson manual which summarises their different small printer command codes I could copy, if you fancy writing something. I don't know if there is a collection of printer and plotter manuals online anywhere. BitSavers seems very light on them, I checked recently to see if I could free up the six feet of shelf space occupied by such manuals at my office but no such luck, so I will have to keep hold of them for now. Al seems to be snowed under at the moment, I scanned and sent him the ICT1301 programmers reference manual 12 months ago but it has not appeared yet. Roger.
