Hello. I have an old VAX 730 that needs to be restored, and temporaneously is stored, because of lack of space to disassemble and repair the machine. With the machine it came a box of old cassettes, that I would try to read. Furthermore, I'm working on disassembling the code of a TU58 rom, because I would try to hack the firmware to provide the ability to format an empty DC100 cassette. For this reasons, I'm searching for a TU58 drive in good/repairable condition, if anybody has one to sell for reasonable price. I'm in Italy, so europe is preferred... Andrea

Don Maslin's stuff being sold

by dgriffi＠cs.csubak.edu

I have met with Don Maslin's niece and paid her for several boxes of S100 boards. I have also taken four complete machines on consignment. One of these, a Commodore PET 2001-8 with 11 tapes is for auction right now (http://www.ebay.com/itm/330910987205). I will assist Don's niece via email on photographing and packing the remaining machines (which I was unable to pack into my car) for which I will then run auctions when I get settled in Bellingham, WA. I will probably pass this effort along to someone nearer San Diego. Please contact me privately if you wish to assist in this liquidation or take over entirely. -- David Griffith dgriffi at cs.csubak.edu A: Because it fouls the order in which people normally read text.

[N8VEM-S100:1583] S100-68K-V3 -- A brake at last!

by LYNCHAJ＠YAHOO.COM

Thanks John! That's great news! Yay! http://s100computers.com/My%20System%20Pages/68000%20Board/68K%20CPU%20Board .htm Now that the S-100 68K CPU board is working I'd like us to consider either a PAK68/2 and/or PAK68/3 for it or a 68030 native board. Especially one that could use the top connector for the 8MB or 32 MB SRAM board. I am thinking a 68030 native board would be about the same complexity as the S-100 80386 CPU board and even share elements of the design. Thanks and have a nice day! Andrew Lynch From: John Monahan [mailto:monahan at vitasoft.org] Sent: Friday, April 26, 2013 2:00 PM To: n8vem-s100 at googlegroups.com; 'yoda' Cc: Andrew Lynch Subject: RE: [N8VEM-S100:1583] S100-68K-V3 -- A brake at last! Good news guys, finally got a brake on the 68K board. Now have it working R/W S-100 RAM (4MG Static RAM board) with a 12MHz oscillator (bus clock 6MHz). The problem is embarrassing, a poor solder joint to ground on U32! You would think by now I would have seen this earlier. Should have check more carefully before the build - I never learn. My tip-off was that an old Godbout 64K RAM board worked fine - did not require upper address lines! Feel somewhat relieved, but we are still not out of the woods. At these speeds the board does not work reliably in the extender board (but OK at lower speeds). In contrast the 8086,80286,80386 have absolutely no problem far higher speed (bus clock 10-12MHz). Timing is clearly tight. I will try and tweak things. Dave, since you are almost there, for me - P2 16-15 jumper halts everything. Does it for you? Stay tuned John

IBM Slides on eBay

by silent700＠gmail.com

Did anyone on the list end up the winner on this set of slides? http://www.ebay.com/itm/190828071637? If so, I am probably not alone in hoping to see these scanned and posted online someday. -- silent700.blogspot.com Retrocomputing and collecting in the Chicago area: http://chiclassiccomp.org

Very Frequently! Personally, I've learned a lot from all the highly intelligent answers people have given resulting from supposedly stupid questions (such as those by "MG" which I was in no position to judge), or other inane remarks. Truly inane -- especially singular -- remarks, such as you will undoubtably claim these of mine to be, can simply be ignored rather than be pontificated on in any or every single instance. - John

1972 Harris Semiconductor Catalog

by shumaker＠att.net

Recently acquired one at an "estate" sale for a minor sum... It's a quite musty but very readable 3 ring binder will the entire Harris semi line as of 1 Jan 1972. Including their early ICs and some app notes. I've already scanned it for my files. If anyone on the list would like this thing free for shipping from 95006, I'll pass it on. The binder has mildew and water stains and it has a very musty smell about it... but otherwise in ok shape.
