For free, Multia VX42 (233MHz 0/0) and SPARCstation-2 and IPC 64/0. Pick up in Renton, WA or near environs. The Multia is in cosmetically good shape but the battery died with the OVMS firmware in place - for those unfamiliar with this machine that means to make it work you'll have to replace the battery and do a failsafe load. Also have the Performa version of the Power Macintosh 6100/60 and a IIci. IIci is loaded with memory

New absolute filters for DEC RL01/2 drives -

by jack.rubin＠ameritech.net

I found a cache of NOS RL01/2 absolute filters (equivalent to DEC p/n 1213097) at the Filter Factory in Santa Ynez, California (www.thefilterfactory.com), phone 805.733.2180. They have 47 in stock. Price is $28.60 each, shipping for a single filter to 60091 (Illinois, USA) was $8.27. I ordered one to verify dimensions and construction - perfect match for the original part. The filters were manufactured by HEPA Corporation (still in business) but minimum order quantity >from HEPA is 100 units. Filter Factory will _not_ be ordering after the current stock is gone. Get'em while you can! Jack

Terminal trouble

by saquinn624＠aol.com

I have a Wyse WY-150 that I use as a console for several machines, and it has an odd and irritating behavior on some machines. For SGIs and DECs the text gets messed up. O300 will get garbled, but my suspicion there is that the terminal doesn't really handle 38,400bps right. On all SGIs and DECs there are spacing issues, though - Example: in SGI startup diags and PROM whether I'm in 80 or 132-column mode there will be one letter on the far right and then it wraps around. I'm in VT220 mode, and it does it in both 7-bit and 8-bit. I didn't notice this on my old Altos III-branded Wyse. Anyone fixed this?

Terak fonts and images

by jfoust＠threedee.com

I was recently motivated to write a few tools to convert Terak fonts and images to contemporary formats. I've added more than a dozen original Terak bitmap images, an animation, plus 26 Terak bitmap fonts converted to Windows. <http://www.threedee.com/jcm/terak/>http://www.threedee.com/jcm/terak/ - John

CP/.M Floppy Bood Diskette needed...

by lbickley＠bickleywest.com

I recently acquired a Televideo TS-801. It's a typical Z80 CP/M system. I've have it restored to where it is trying to boot. It "says" that it is in the process of "IPLing" the system and the left drive is selected. I couldn't find any TS-801 boot images, but based on CC archives, I saw that Televideo TS-802 floppy images will work as well. I downloaded TS-802(H) images from Dave Dunfield's site - but they expect a HDD - and fail booting... Does someone have an CP/M boot image for the floppy based TS-801 or TS-802? If so, I'd appreciate a copy off list or link to same on or off list. Thanks! Lyle -- Bickley Consulting West Inc. http://bickleywest.com "Black holes are where God is dividing by zero"

Fwd: HP 524B Military Version

by hilpert＠cs.ubc.ca

I have been contacted by a fellow with an FR-38D/U digital counter, I gather he would like to let it go. This is a tube-based digital electronic counter, identical to the HP-524B, but I think the particular unit at issue was actually manufactured by Northeastern Engineering. (I've never understood the relationship, but AIUI Northeastern manufactured/second-sourced some HP designs.) Here is a photo of the unit: http://i142.photobucket.com/albums/r84/onegroovydude/ 62E116DF-2C75-459F-ADE4-44FA2B79B712-285-00000017B3222DC6.jpg For more info about the models, here are my web pages about the 524B and HP-520 instruments: http://www.cs.ubc.ca/~hilpert/e/edte/HP524B/index.html http://www.cs.ubc.ca/~hilpert/e/edte/HP520/index.html These things aren't computers of course, but they are some of the last pieces of tube-based digital electronic instruments, i.e. the same technology as the the 1st generation of electronic computers. Marketing spiel: You're not likely to ever own a digital tube computer, but you can own a digital tube counter. I'm just helping to see it preserved, you can contact Travis below if interested. I get questions and expressions of interest in these instruments every now-and-then due to my web pages, but I have no idea what sort of dollar/market value to assign. The location is Kansas City. They're over 100 lbs and you'd have to be really enthused to have it shipped - so hopefully someone can pick it up. If someone obtains this unit, I can supply the schematic, at least for the HP version. (I have a 524B and 524C that I have repaired.) If someone does obtain it I'd be interested to hear about it.

Very wise words, I'd not expect anything less from you :o)
