I have a fine old Stag PPZ modular EPROM programmer: http://www.gifford.co.uk/~coredump/inst.htm#PPZ It takes plug-in EPROM (model Zm2000) and PAL (Zm2200) modules, called Z-modules by Stag. I've recently acquired a new module, Zm3000, which looks like a more recent EPROM module. The chips in the Zm3000 are date coded in 1993, whereas the Zm2000 is nearer 1988. The PPZ main unit contains a 6809 CPU and a small CRT display. Does anyone know anything about this system? What about other Z-module types? In particular, should the Zm3000 work with the PPZ, because I currently get an error message "Incorrect Mainframe"? Thanks in advance for any clues!

Iomega Bernoulli Box 20+20 (A220H)

by mbbrutman-cctalk＠brutman.com

I rescued one of these ancient Bernoulli boxes today. It uses the large (8") cartridges at 20MB each, and it has two slots for the cartridges. Other than for hearing some of the folklore about the drives, I don't know much about it. I'd like to see it run and be usable, but I need some help. - Is it SCSI? If so, what's the pinout on the back? It has a 37 pin female connector that I'm not familiar with if it is SCSI. - Where is the head mechanism? Is it fairly robust and protected if there are no cartridges inserted? This one has no major dents, but it has not been babied either. I don't want to waste time on it if it's just going to be a heartache. (I have enough of that already.) - Cartridges look like they are on eBay. They are cheap enough for me to experiment with. - Is there anything I should know about these beasts before I attempt powering on and working with it? Thanks, Mike

Anyone off to VCF-UK

Frankly, although I'm sure that most people on here are nice folks, there's only a handful with whom I think I'd have much in common and would spend time and money to hang out with and listen to if there weren't something else that interested me (especially since I don't drink beer or eat pizza). Having read some of these comments and especially the sentiment that unless you're a "celebrity" who cares what you have to contribute, I'm thinking the same as Tony, namely why am I wasting my time here? I've got friends who share my interests and there aren't any ignorant jerks like Evan among them nor do they tell me to fuck off; maybe it really is time to rent a dumpster and just toss in those Cromemcos, Vector Graphics, PETs, AIM65s and the 25-odd boxes of manuals and documentation that are taking up space just in case someone might want or need something one day; with a couple of exceptions they certainly aren't any use to me. Something to think about for sure; I may end up actually thanking Evan one day for finally showing me the light.

OT: Worth exhibiting at Maker Faire?

by evan＠snarc.net

Hi all -- My club (MARCH) is scheduled to exhibit at the inaugural Maker Faire NYC. I'm starting to have second thoughts because we don't "make" anything, we just make old things work again. Who here has been to a Maker Faire event, and if so, would a vintage computers exhibit be well received by the audience?

GNT 3601 tape punch docs?

by chrise＠pobox.com

Probably a stretch but wondering if anyone has any info (manual, pinouts, service documentation) for a GNT model 3601 8-bit (1") paper tape punch. It was probably better known in the CNC / automated machining world than in computing but my hope is to resurrect it as a backup punch for copying tapes I use with my ASR-33 and thereby save wear on the -33's punch. The unit has serial and parallel interfaces on DB25 connectors but I do not have any pinout information for those. The serial one I can probably figure out. Unfortunately, the unit is a little more sick than "works OK" seemed to imply from the eBay seller. It has what I believe to be a power supply problem because as soon as you try to punch all eight holes with the front panel test button, the power LED dims and the punch jams, apparently from lack of umph to complete the mission. It could also be jamming to start with and that causes the power drop I suppose. In any case, looking for any docs before I open it up and start digging around. I have written to GNT without a reply so far. Chris -- Chris Elmquist mailto:chrise at pobox.com

For sale: Some DEC stuff

by hachti＠hachti.de

Hi folks, anybody interested in buying the following? - Omnibus core memories (tested good) - M8350 TTY interfaces (tested good) - RK05 disks for pdp11 (12 sectors) (used, new, tested, untested) - RK05/RK05J/RK05F disk drive (untested, tested good, broken) - RK05x spares - TU56 DECTape (tested working, untested, broken) - TU56H single DECTape - PC05 paper tape reader/punch - Some other Omnibus cards PDP8/M ******* A PDP8/M computer. Very nice (near perfect!) condition front panel. Chassis condition lower medium condition. Backplane and PSU (220V) ok. No top cover. System configuration to be discussed. First guess would be 12K core, TTY, CPU - all tested stuff. PDP8/L ****** PDP8/L minicomputer, untested, keys bleached out by sun. Untested (really untested, currently don't have the time to repair the machine) but complete with the 4K core stack. 110V Keys kan be used from a pdp8/e - they're the same. But not from pdp8/m. Those have the wrong colour. The PC05 is a strange machine: The reader portion of it was used on a pdp8/e (PC8E interface). Normally you use PC04 for pdp8 computers. The reader part seems to be compatible. The punch part is untested. Mechanics look fine. I guess that there are also missing boards on the punch side. Nice condition though. No cover, 110V. Location: Northern Germany (Hannover, Kiel). Open for reasonable offers. Can send packages up to 30kg. TU56 can be shipped in two packages. pdp8/m fits a package. 8/L cannot be shipped internationally. Kind regards, Philipp -- http://www.hachti.de

Apple Lisa 1 for sale

by sellam＠vintagetech.com

I have an Apple Lisa 1 for sale. Yes, it has the Twiggy drives. It includes the Twiggy systems OS disks (2), original Lisa 1 manual, keyboard, original Lisa (rectangular button) mouse. It works. Excellent condition. Normally I would not so brazenly hawk something but I need to raise funds for an imminent move of the VCF archives. I'm entertaining any and all offers. At a minimum, there should be three zeroes before the decimal point. Please contact me directly if you're interested. Photos and more detail will be forwarded upon request. Will ship galaxy-wide. Thanks! -- Sellam Ismail Vintage Computer Festival ------------------------------------------------------------------------------ International Man of Intrigue and Danger http://www.vintage.org [ Old computing resources for business || Buy/Sell/Trade Vintage Computers ] [ and academia at www.VintageTech.com || at http://marketplace.vintage.org ]
