HP 16702A logic analyzer failed Ethernet (was Re: dumping Western Digital Microms)

by spacewar＠gmail.com

I wrote about my HP 16702A not working on Ethernet any more.

I also tried connecting the 10base2 to a 10 Mbps hub, and another port to my "real" network, and that still didn't work. As HP-UX boots, it says: <timestamp> auto_parms >> Network was disabled by boot scripts on previous oot. Re-activating the network. 8/16/6 <macaddr> 0 UP lan0 DOWN 4 ETHER Yes 52 <timestamp> auto_parms >> /sbin/auto_parms, checking network for DHCP server (see /etc/auto_parms.log) Then in the progress list, it shows: Configure LAN interfaces .................... [FAIL] * Check LAN Status .............................. [N/A ] [...] Configure HP Ethernet interfaces ......... [ OK ] Configure HP 100BT interfaces ............ [N/A ] Configure LAN interfaces ..................... [ OK ] Then once the logic analyzer application is up, it shows an error log window, which says There was a DHCP error . Network was disabled. But if I go to network settings, it says: Network hardware not usable - Is the network connected? And all of the radio buttons (e.g., to select "standard" configuration instead of DHCP) are greyed out and I can't configure it. I think the Ethernet ports on this beast are dead. :-( I'm not sure whether it's the CPU board or the I/O board that is dead, but Keysight, or whoever they are this week, wants more money for either of those boards than eBay pricing for a used 16700A or 16702A.

The machine wiring does not match the CLC page, so maybe there are more recent ECOs in the machine and not in the prints. We visited the RCS/RI crew last weekend and used their PDP-12 to format some LINCtapes. At least we have some freshly formatted, known good, LINCtapes for the TC12 debugging.

UA11 boards

by ggs＠shiresoft.com

Hi, I know it?s been a while (a long while) since I last posted about ordering new UA11 boards. I just placed an order for 25 boards. To get the best price I did a ?4 week turn? which means that I should be receiving the boards by the end of January. I?m only doing bare boards this time, so what you?ll get is a board and a set of printed documentation (which is also available at: http://www.shiresoft.com/downloads/docs/ua11/UA11%20Manual.pdf). I just looked at the documentation and the address and phone numbers are old (so don?t try and use them!). I?ll try and get the documentation updated with current information before I ship any boards. The cost will be less than what?s posted on the website, I won?t have exact numbers until I receive the boards however I expect to charge ~$100/ea + shipping. I?ll let everyone know when the boards arrive, but feel free to email me (off list please!) if you?d like to reserve one (or more!). Do not send any payment until I have boards in hand! Have a Merry Christmas (or whatever your preferred holiday this time of year is)! TTFN - Guy

XY11 Manual, Anyone?

by mattislind＠gmail.com

I have in mind to connect a machine to an IBM 1627 (CALCOMP 565) plotter and then the XY11 which just arrive would fit nicely, I think. But I cannot seem to find any manual for the XY11. Anyone know of a manual? The board is rather simple so it should be possible to work out the details on how to interface it by hand but it would be nice to have the proper manual. Then for software I found a diagnostic, XXYAD0 that supposedly should draw a square and a rectangle. Anyone know of other drawing software that uses the XY11 /Mattis

dumping Western Digital Microms (PDP-11, WD16, Pascal Microengine)

by spacewar＠gmail.com

The DEC LSI-11, Western Digital WD16 (as used in the Alpha Micro AM100), and Western Digital Pascal Microengine use variations of the same chipset, called CP1600 for the LSI-11 and WD16, and WD9000 for the Pacal Microengine. The chipset consists of a control chip, a data path chip, and two to four microcode ROMs, of 512 words of 22 bits each, known as "Microms". I built an apparatus on a breadboard to dump the contents of Microms, using a PIC and a quad gate driver to produce the four-phase 12V clock, three 74HCT163 four-bit counters and two 74HCT245 buffers to drive the address onto the microinstruction bus, and a 74HCT4050 and 74HCT04 to level shift the MOS phase 2 clock back to 5V and invert it, to enable the 74HCT245 buffers. Photos: https://www.flickr.com/photos/22368471 at N04/albums/72157662054690240 The apparatus cycles through the entire 2 kibiword address space continuously. An HP 16701A logic analyzer with 16557D state/timing card is attached to capture the addresses and data. Because the microinstruction bus is active low, the addresses are driven in reverse sequence, and the microinstructions captured on the logic analyzer are inverted. So far I have dumped the following LSI-11 Microms: 3010D, DEC P/N 23-001B5 (also designated CP1631-10) - addr 0x000-0x1ff 3007D, DEC P/N 23-002B5 (also designated CP1631-07) - addr 0x200-0x3ff So far I have dumped the following Pascal Microengine Microms: WD2171-10 - addr 0x000-0x1ff WD2171-12 - addr 0x200-0x3ff WD2171-13 - addr 0x400-0x5ff WD2171-14 - addr 0x000-0x1ff WD2171-15 - addr 0x200-0x3ff WD2171-17 - addr 0x400-0x5ff WD2171-18 - addr 0x400-0x5ff There exists at least one other Pascal Microengine Microm which I don't have, the WD2171-16. I expect that it probably occupies addr 0x400-0x5ff. I have not yet dumped the WD16 Microms as I do not have an AM100 CPU board at hand. My next challenge is exporting the data from the 16701A to anything else. The 16701A used to work fine on my Ethernet, but for mysterious reasons it now claims that the network can't be accessed, despite that plugging a laptop into the same Ethernet cable works fine. I'll need to write a small Python script to post-process the output, for use with my disassembler (also in Python). Note that dumping the Microm contents is only part of the problem; the control chip also contains PLAs that can force microcode jumps under various conditions despite there being no corresponding jump instruction in the Microms. This is used for macroinstruction decode, and possibly for other purposes.

dumping Western Digital Microms (PDP-11, WD16, Pascal Microengine)

by jnc＠mercury.lcs.mit.edu

> From: Eric Smith > The control chip and data chip are not Microms, and MUST be plugged > into the correct socket. Yeah, as you saw, I eventually figured that out. In part, along with the bad diagram, I was thrown by a combo of the fact that i) the DEC part numbers for the control chip started with 23- (which seems to be a ROM part indicator), unlike the data chip, which as a 21-1; and second, the control chip is 23-002C4/23-003C4, which was so close to uROM numbers like 23-002B5 and 23-003B3, it sounded like they were all uROM parts. > There are a number of variants. Thanks for all the additional data. I'll add it all to the LSI-11 page on the he Computer History Wiki (seems as good a place as any to accumulate it). Noel

Has Anyone Written PDP-8 .XOR. Code Using the MQ Register (Without the EAE)?

by bobvines00＠gmail.com

Has anyone written PDP-8 code for .XOR. that uses the MQ Register (when the EAE isn't available)? If so, can you share the source code and/or the algorithm? Thanks, Bob

Also a lot of info on using the LPS-11 too. There are plenty of copies out there and quite cheap too. It's an excellent book and could be of use to you. Steve.
