8/L has been sold. Have ADM-3A for sale.

by charlesmorris＠direcway.com

The 8/L, ASR33, DF32 disk emulator project has been sold. Thanks for all your interest (and offers). Anyone who wants the DF32 emulator schematic and artwork, I can email you a copy. I hope someone can take my "first draft" and make a useful unit for those who are interested. I have a working ADM-3A that I may want to sell also. It has a homebrewed lower-case 2716 ROM (thanks Steve Loboyko for the font files). I installed the "optional" parts for current loop on the main PCB, and used it with the 8/L. The only thing that's missing is the little aluminum panel covering the dip switches. Any interest? Same deal as before, please email offers, "sealed bids". thanks Charles

Atari 800xl "translator disk"?

by dbetz＠xlisper.com

I have an Atari 800xl and a couple of 1050 disk drives. I also have two copies of the M.U.L.E. game on disk. Unfortunately, I can't get either to boot on the 800xl. I suspect that these are older games that were written for the 400/800 and may need the "translator disk" that allowed the 800xl to run games written for the older machines. Does anyone know where I could obtain a copy of this translator disk? Thanks! David Betz

Stag PPZ EPROM programmer

by coredump＠gifford.co.uk

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!

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

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.

Reading NorthStar Horizon hard sector disks on PC

by marvin＠west.net

> From: "Chuck Guzis" <cclist at sydex.com> > Not all Northstar diskettes are HS.

I think the machine you are thinking of might be the N* Dimension. The Advantage still uses 10-sector floppies. I've never seen the Dimension but vintagemicros on Ebay was selling one a while back and had a picture of it. Apparently it was MS-DOS compatible.

Catweasel support for Intel M2FM working!

by snhirsch＠gmail.com

I'm pleased to announce that the maintainer of Linux cwtool has implemented working support for reading and writing Intel M2FM "DD" diskettes as used with the Intellec development systems :-). Karsten did some analysis of raw bit images I sent him and produced a working driver within a week! As a "smoke" test (my MDS800 is not functional at the moment), I duplicated the ISIS-II system diskette and sent the copy to a person with a working system. It boots, catalogs and otherwise looks fine. I have about 20-25 original distribution diskettes for the MDS800 and will get busy imaging them ASAP. Who would be willing to host these? They are "cooked" images, so it would be possible to extract the files >from them with a bit of work. However, they're obviously of the most use to folks with access to a Catweasel board (and an Intellec system). Steve --
