Uh, I know what you've got in mind, but you will not be able to swap the "interface" board to a different HDA. Reason is, when these are made, the board is 'married' to that HDA using jumper settings and stuff (the ones with glyptol dripped on them so you can't remove them by accident). Each one is different (it has something to do with the servo head, I think).

GeoWorks -- Commodore/Apple/PC?

by roblwill＠usaor.net

Hi! I Used to have a Commodore 128 that had GeoWorks on it (I think it was actually GEOS, or something like that). I also have a box and font/graphics set for the PC version or GeoWorks. I've also heard that there was a version of it for the Apple // series. Does anyone have a copy of the Apple version that they would want to sell (or copy)? I also have a font/image pack for the PC version, if anyone wants a copy (I'll have to check them to see if they're good or not first, though. -- -Jason Willgruber (roblwill(a)usaor.net) ICQ#: 1730318 <http://members.tripod.com/general_1>

<The IBM entry into the PC market was in mid-1981, I think, and the Model-3 <was rushed to get out ahead of it. The Apple-II exlposion wasn't quite <underway yet, but the handwriting was on the wall. No. By then the apple and trs80 were common as house flies. In fact in 1980 we used Apples and TRS80s running a similar program for forcasting as they were in wide use around the shop. They were both in the market in terms of volumes nearing a 500k system each if not more by 1980. the PC wasn't an impact until 82 maybe 83. Memories and events seem to get compressed or expanded. I's even say the PC was not a serious contender till mid 83. Allison

new hamfest additions

by SUPRDAVE＠aol.com

one good thing about being a hamfest vendor is that you get to see what's for sale the previous night and free food. so far, i bought an apple /// with profile. what's even better is that i got a bunch of documentation and system disks with it like business basic, device driver manual, apple access ///, apple writer ///, owner's guide, apple backup, utilities, profile drivers and demos. even got the owners manual and a copy of castle wolfenstein in original packaging. time to make backups of all this stuff. mostly pc items for sale, but did see a few portable PS/2s and some S100 bus cards. are they worth picking up? also bought 10 TI99 carts and the speech box earlier today.

Hi! This is possibly too new for this list, so please excuse me if I offend anyone... I was wondering if any of you might have a copy of PCMICA drivers, such as might have been shipped with a modem or other card?

8/E PSU resolution

by mbg＠world.std.com

I didn't get a chance to take pictures of it today, but I did take a look at my 'long' 8/e... The cover is solid. I didn't take a look at the hinged side, but the latch side has hexagonal holes for venting. The tolerences seem very tight between the metal of the case and some very exposed wiring terminals... As for my 8/e, although it hums when I apply power, nothing happened when I turned it on... I checked the fuses, and one of them is missing... I'll try it again when I replace the fuse (I really should have checked that to begin with...)

Variac

by dastar＠ncal.verio.com

I have a Variac here that I need help connecting up. The terminals on it are as follows: O 2 4 O | | wwwwwwwwwwwwwwwwwwwwwwwwww / \ O O <--><------100V------><--> 20v | 20v O The "2" and "4" are what is labelled on those terminals. The "O" are the terminal connectors. The "w"'s are windings as depicted on the terminal panel. The panel also shows the voltages as depicted. I'm assuming the output is 2 and 4. But what is the input? The 20v sections seemingly say that you can tap off of them to get some combination of 20V, 120V or 140V? Please help!

PDP-8/E PSU Debugging (was Q-bus pinout)

by allisonp＠world.std.com

<Too bad it's wrong. It misses a few details bit it is essentially correct. Do research before you indite the document. <It makes it seem as if there was a box that was designated PDP-8/E and it <had a particular configuration that was retired until the introduction of <new box with the designation of PDP-8/F. This isn't supported by the eviden No. read the whole FAQ to get the full picture. that was an excerpt. <What really happened, and I have several independent confirmations of same <is that the PDP-8/E system evolved into the PDP-8/F in a series of steps. <Depending on the date code the machine was configured differently. Yes and sorta. the 8E was the large box and remained as the "big version". As a cost moderating measure the smaller 8m/f versions were created for more limited expansion and with a lower basic cost. <The evolution vectors were as follows: < Module updates - example M833 - M8330, M831 - > M8310 Bug fixes. early in the 8E life and nearly predating the later omnibus 8s. The original designs had poor margins and too much green wire. Even later ones have green wire. < Chassis updates - Long box, single OMNI BUS < Long box dual OMNI BUS < Short box single OMNIBUS Linear PSU on side. < Short box single OMNIBUS Switching PSU in Rear version replaced the really broken side mounted PS version. The switcher was not the best design as it was fairly new technology. < Front Panel Updates: Diode logic + 8v LAMPS Early 8Es only. Driven by manufacturability. < TTL logic + 6v LAMPS Bulk of production and the common verison in the 8E < TTL logic + LEDs in lamp sockets Never made, it was a field third party retrofit. < TTL Logic + LEDS 8F/M pannel later in design than the 8e v2. < PSU updates - Long linear PSU < Short linear PSU < Short Switching PSU (types A and B) Not updates litereally differnt products with overlapping production lives save for the two switchers. <At some point in this evolution some marketroid decided to change the name <from 8/e to 8/f. The OEM version of this platform was called the 8/m and Sorry no! the 8E remained in production and the 8f was the short 20 slot machine and aimed at lowering the cost for those that didn't need/want 38 slots. <included an optional limited function front panel (although all 8/M's I've <seen so far had the programmers panel but that's only about a dozen so who <can say) The 8M was a fairly standard menu machine with the limited function panel. It's options included a full function pannel (if you were a volume customer custom colors and board mixes). <I happen to have an 8/e that is: < Short box < 6v LAMPs plus TTL front panel < Side mount PSU That is not an 8E, it a frankenmonster in a 8m crate. <I recently picked up an 8/e chassis that had the dual OMNIBUS backplanes. That is an 8E. <It is this one that doesn't have a cover. It may have been mounted in a <desk, I don't know (it also didn't have a front panel but I can use my <other 8/E front panel with it) The 8e was the model with the long linear PSU on the side and the dual omnibusses. <My guess is that the evolution of the 8/E was driven by the introduction o <the 11/20 since these changes seem have occurred between 1970 and 1972. Al No. the two were entirely differnet development and had the common thread of newer low cost TTL available. <8/E's with date codes prior to 1970 appear to be the diode front panel <type, All 8/E's after 1972 appear to be either 8/F's or 8/Ms (until the 8/ <came out). 8Es were 1970 introduction. Parts will have datecodes up to a year older than that. <The 8/M and 8/F are primarily differentiated by different inserts/color <schemes, electrically they appear to be identical. The solder mask of the <front panel says "8/E" The same pannel was used for all. It was an assembly level options that set them apart. Since parts were swapable there were a lot of variations due to parts being moved as needed to maintain systems or make working ones. The omnibus series of PDP-8s were all driven by lowering costs and product improvements. Even the later 8As were KK8e cpus (m8330/8310/8320/8300). The actual 8A CPU (kk8a?) was a hex module. Allison

source for foam filter material

by edick＠idcomm.com

At your local discount store, you should be able to find some fairly large scouring sponges, I've found that these work adequately as filters, provided you put a layer of porous cloth over the downstream side to catch the finest particles. If you're fortunate enough to find the really fine ones, the cloth isn't needed. These come in 1/4" thick postcard-sized sheets, which I usually cut up anyway, so give these a try and see if they meet your needs.
