PANASONIC HHC RL-H1800 TV DISPLAY ADAPTOR

by n8uhn＠yahoo.com

WOW! someone spent alot of time reverse engineering the hhc and i thank you. i downloaded the schematics. so far i have a lead on a 1400 hhc which should be of use for the programmer or just a display board swap. i have a large bid on ebay for a ge programmer that has an 1800 with a working display and some spare ge modules. im still wondering if the tv display adaptor will work with the ge software but, it seems one cannot be located. anyone know if the tv adaptor has a rom in it? if not, it could be built of some perfboard if the chips are still available. i think i should be good with a working display - i was concerned with display rot but, it seems mine is the only one i've seen that the display went bad in 1 area. others pic's i've seen online all have good displays on them.

PDP-11 / Unibus: config info for Motorola Memory Systems MMS1117 MOS board?

by js＠cimmeri.com

Folks, I'm restoring an 11/34A. One of the MOS memory boards it came with is a circa 1979 Motorola model "MMS1117", variation "58 PC" (64KWords / 18 bits / w/parity). Would like to know if anyone out there has configuration information for this seemingly uncommon board? It's a very high quality board and has socketed RAM, so it'd be especially nice to be able to keep using it. It has 5 switch packs (only 2 of which have markings) and at least a dozen jumpers. I've only been able to locate performance specs for it at: http://bitsavers.trailing-edge.com/pdf/motorola/_dataBooks/1979_Motorola_Me… .... which are excerpted here: www.cimmeri.com/js/download/MMS1117.pdf .... and a photo of the board is here: www.cimmeri.com/js/download/MMS1117.jpg ... a photo of the system itself is here: www.cimmeri.com/js/download/11$34-20.jpg Any help, very much appreciated. Thank you, John Singleton

what chip is that? IBM Displaywriter 6360 Diskette Unit

by rampaginggreenhulk＠yahoo.com

Not likely even in my mind, but the NEC APC utilized both a WD FDC and the 765 via an aftermarket add on. I originally wanted to state that the stock unit had both, but I'd really have to check on that. That part # is 8665. Rockwell used the house # 6765 for their 765 clone. Intels wasx 1272 or 1772 oi I just woke up. This much I do know. The APC comes w/8" drives and utilizes a 765. The aftermarket board which allows for 5 1/4" drives has a WD chip. Go figure.

HP 9000/375 Added to the Collection

by jjacocks＠gmail.com

So, I picked up another old workstation, this time an HP 9000/375. I did a basic clean-up and test, and it does seem to work. With a reversed VGA-to-5BNC cable, I can see the diags run on the monitor. It has 8mb of RAM. So, questions, if anyone here has any knowledge about these beasts. 1) I have the HIL-PS/2 adapter (HP calls is the "keyboard adapter module"), but it doesn't plug in to the HIL port on the machine. There is a descending piece of plastic on the right side of the 10P10C connector that blocks it. I know that this adapter was made for the 9000/700 PA-RISC workstations, will it work with the 375, if I remove that tab? 2) What kind of memory do these machines take? I find reference to a 32mb kit (of 2 16mb modules) via HP part number 98229E. The specs say that this machine will take 128mb. So, should I just try to track down 4 kits? Any other advice would be welcome. This is my first 68k workstation, and I'm hoping to have more, in the future. Thanks! - Alex

PANASONIC HHC RL-H1800 TV DISPLAY ADAPTOR

by n8uhn＠yahoo.com

Hi All, I have an rl-h1800 HHC that is part of a GE two way radio programmer. the display is not displaying full characters from the middle of the display to almost the last third of the display and i noticed that a tv display adaptor was available for the hhc. anyone have one or know where i can get one? i haven't checked out how the display is wired into the hhc but, i'm guessing that it used the flex strip or worse yet, that rubber multi conductor bridge strip with the microscopic wires. has anyone fixed loss of dots on the single line lcd? the ge suitcase programmer does have the i/o expander and also has the printer along with two custom i/o boxes for the radio interface and eprom radio program storage box, so, i do have room for a display adaptor. Thankx, Bill

Stardent documentation now online; Dore' documentation wanted

More DEC Module photos

by v.slyngstad＠frontier.com

Hi, Having finished the work for the modules used in the straight-8, the 8/S, PT08, TU55, and the TC01, I'm moving on to other PDP-8 modules. Toward that end, I've made a list of what I'm missing for various pieces of gear related to various models of PDP-8. What I'm looking for here is fairly decent resolution photographs of the component and solder sides of the boards, so I can do the placement and routing accurately. Any revision of these boards is fine for this initial work. 8/L: M703 M705 (I also need these same modules for the 8/I.) 8/I: M702 M703 M704 M705 M714 M716 TC08: G879 M228 M633 M916 PDP-12: A215 A404 A811 G718 G780 G783 G793 G916 M141 M166 M711 M720 M760 W078 Linc-8: A130 B117 B171 G906 R122 R410 W024 W031 W035 W072 W073 (I imagine these will be the hardest to locate, as there are very few surviving examples of some of them.)

Think "PADDs" in Star >Trek: TNG. > > -Dave You keep pulling me into something that'll likely turn into a rant. I am no fan of TNG, and I don't know what they are. I know the original series was considered pc in it's time. But TNG was order of magnitudes more so. So much so I'm sure if it was produced today, Riker and Picard would be having sex in the turbolifts between decks.

I realize there are roms you can substitute (and haven't heard of that one, previously preoccupied with Zenithink, thanks), but you could brick your tablet in the process, as well as void your warranty. I will root mine prior to the year mark. A bit queasy about swapping out roms though. I'll at least have to see if it's been done on my unit. Is yours the original Nook or the Nook tablet (not the latest)? Are you delving into A* at all?

I'd probably be interested in whatever you got. Why did I sell my Rainbow?? I've sold off 3 in less then a year! Never did find a color card. O sher this stuff is easy to find. Keebees maybe.

Manual for BASF6105 8inch Flp drive

by rampaginggreenhulk＠yahoo.com

All those bits of rubber are now blobs of goo--and tough as the devil to get cleaned up, much less replaced. Try GooGone and a host of other things. Can't say for certain but I have to believe there's some way of removing it w/o too much fuss. Tape residue and I realize it's entirely different comes right off with what used to be called Afta, but they were bought by someone years ago.

Cross country hauling available.

by wdonzelli＠gmail.com

Once again, late-April/mid-May will see my roadtripping across the country, from coast to coast. I have quite a lot of unclaimed space that I need to fill up. As in the past, I am offering to move vintage computer equipment for a decent price from source to your doorstop - single items like bulky terminals to six foot racks to mounds of documentation and tapes. Prices are quite reasonable, especially seeing how much freight costs have exploded recently. I can load from just about anywhere, and unload just the same. All items get great care when being loaded, shipped, and unloaded. At this point, it looks like the journey will be New York to Chicago to Denver to Salt Lake to Seattle to San Jose to San Luis Obispo, then back to Boulder to Chicago to New York. At this point, only the Denver to Seattle portion is completely booked, however, this has not been confirmed yet. I also have partial loads from New York to Denver, and hopefully a partial load from San Jose to New York. So, if you need something rescued and hauled, please contact me off list, and we can see what can be done. -- Will

Houston Area help

by wdonzelli＠gmail.com

I may need some short term help with a museum pickup in Houston. It is a small item (well, sort of - 50 pounds? Certainly trunk of the car small), but would need pickup in 15 days or so. It is a piece of avionics gear. Expenses would be paid, of course, to fetch this and probably ship it (unless I swing by Houston soon). Any interest? -- Will

anyone ever use a USB/Serial cable to connect to an Altair? I am trying to connect my 680b to my windows 7 computer via hyper-terminal to no avail.

Thankx for the info. i did read that in the manual and since the ge software only uses text on the single line display, i am hoping it will echo it on the adaptor. unless the adaptor need's to be specifically called in the software to do the echo via the i/o channel,in which case i'll still have to fix the display or change it.
