Hi, Apologies for the constant stream of questions at the moment, I hope I'm not consuming too much list bandwidth at the moment. I've brought my whole collection out of storage and I'm bringing them all back to working condition and going through a steep old learning curve with my Unibus machines! So here are the latest round of questions: 1. I have started work on a second 11/05 I have. At the moment it has a processor, an 8K core set, NPR cards and a pair of unibus terminators. At present when powered up the machine has its run light constantly on, shows what looks like a random set of lights on its address/data LEDs and doesn't respond on its console. I have tried swapping the CPU boards and core cards for known working cards with no success. I have also hooked up a scope and confirmed the power supply is supplying correct voltages. Any ideas on what could be causing the bus error? 2. I have a Plessy PM1116/B core card. This is a single slot solution consisting of driver/sense logic on a card and a core plane on a daughter board. Does anyone have any details/documentation on this card or any idea of what slot would be suitable to plug it into (on a 5 1/4" 11/05-8KW backplane). 3. I have an 11/34A (in 5 1/4" box) which is experiencing a similar constant run light problem to the 11/05. The machine has CPU cards, terminators, console card and a MOS memory board in it. With both terminators in, run light stays on. If I halt it, the bus error light is illuminated. If I remove the end terminator and power on, the console is responsive and I can deposit values into memory and read them back. As with the 11/05 I have connected a scope and checked the power lines are supplying the correct voltages without any oscillation. Any ideas?

Boot Disk Needed for Kaypro 2X

by laptoplarry＠gmail.com

The boot disk I have is looking for Turbo ROM. I guess I need one for the 2X (without Trubo ROM). Please help or point me in the right direction. Thanks! -Larry -- This is not an automated signature. I type this in to the bottom of every message.

What do you mean by "NPR cards"? Technically there is no such thing. There is the bus grant cards, and the extended bus grant cards which also carry the NPR signal. The normal bus grant cards only carry BG signals, and thus you normally need to connect/disconnect the NPR wire on the backplane. The symptoms you describe sounds pretty much like an NPR signal problem, but of course, it could be a number of different things. > 2. I have a Plessy PM1116/B core card.

Normally I seem to remember that memory cards can go anywhere. You should of course check documentation, as the card can require specific voltages only available at certain slots. I don't have any documentation for that card. Bitsavers perhaps? > 3. I have an 11/34A (in 5 1/4" box) which is experiencing a similar > constant run light problem to the 11/05.

Once more: check the NPR signal. Johnny -- Johnny Billquist || "I'm on a bus || on a psychedelic trip email: bqt at softjar.se || Reading murder books pdp is alive! || tryin' to stay hip" - B. Idol

Source for 20Mhz. DIP Z80

by snhirsch＠gmail.com

They exist, and are listed by DigiKey and Mouser as the dreaded "non-stock" items. From past experience, this means they will not lift a finger without an order for 1000s in hand. Zilog has, in theory, a sample portal. But they've outsourced their web site to Elbonia and it does not function to the extent of being able to complete my registration. Anyone know a source for onsie-twosies on these? Steve --

DSD Diags disk found

by kyrrin＠bluefeathertech.com

Fellow techies, While cleaning up today, I came across an 8" floppy in good condition, labeled as follows: P/N 060025 REV B DSD 880 DIAGNOSTIC DISKETTE SINGLE DENSITY, BOOTABLE (DSDMON) Considering that I've not done any 'classics' collecting for years, I have no use for it. However, I suspect it should be archived and made available for others. First person to offer me postage/handling costs (say, $5) can have it. Thanks much. -=-=-=-=-=-=-=-=-=-=-=- Bruce Lane, Owner & Head Hardware Heavy, Blue Feather Technologies -- http://www.bluefeathertech.com kyrrin (at) bluefeathertech do/t c=o=m "Quid Malmborg in Plano..."

Gates was a major provider of the single 2V cell in the "D" size with tabs on one end. NLS used three of them but a 6V monolythic battery with the same outer dimensions will also work fine as the tabs soldered to the rear board for mounting and to create a series connection. The only reason batteries are needed to run the NLS is the charger is way too small run run it directly. Allison >Capacity in any given size of box seems to gradually increase over time.
