What's the plan for XT-IDE V2 boards?

by LYNCHAJ＠YAHOO.COM

Hi! Several people have requested fully assembled and verified working XT-IDE V2 boards, so I am selling some on VCGM. I am trying to set up serial production of these boards and am currently working out the details. http://marketplace.vintage-computer.com/auction_details.php?auction_id=1150… There are also several home brew and other vintage/classic computer items on VCGM you may be interested in as well http://marketplace.vintage-computer.com/other_items.php?owner_id=100048 Thanks and have a nice day!

Repairing a pair of IIGS monitors

by alexandre.tabajara＠gmail.com

Time for //GS monitor repair! :oD https://dl.dropboxusercontent.com/u/64631297/1.jpg https://dl.dropboxusercontent.com/u/64631297/2.jpg I fixed my monitor and a friend's one. But both needs replacement of flyback transformer. His can be fixed with a new focus divider, but mine was already repaired (and the guy did a very poor job). Maybe anyone here knows a source of replacement flyback transformers for this monitor. This is the Applecolor RGB monitor, A2M6014, mitsubishi-sourced. Thanks! Alexandre Souza :o) ---

Double good news Friday! Woo Hoo Times Two!

by LYNCHAJ＠YAHOO.COM

[this message went out Friday to the N8VEM-S100 list but may have some interest on CCTALK too. We are at 50% to enough S-100 80286 CPU board pre-orders for a "production" PCB order. There are a few of the S-100 6502 CPU V2 boards left but the stack is shrinking fast.] Hi Some really great news today! Yahoo! First, the S-100 6502 CPU V2 boards arrived! Yay! I will be sending them out to those who pre-ordered first thing! Second, at long last (assuming no more changes) the S-100 80286 CPU board finished trace route optimization! This board is almost old enough to vote it has been optimizing for so long. I am very happy to see it finally emerge out of the basement computer. It is ready for "production" so if you would like to get one or more of these exciting new S-100 80286 CPU boards please do the new usual pre-order. I will set aside your board so you get them right away! Yay! Good news Friday! Thanks and have a nice day! Andrew Lynch

Zetaco SCZ3-2 for Data General

by shadoooo＠gmail.com

Hello. I have a Zetaco SCZ3-2 board, probably a SCSI controller for Data General machines. This board seems to be in good shape, but unfortunately two square sockets (for microprocessor I think) are empty; anyway I could try to find a suitable replacement, if I only knew what kind of IC is needed for. I didn't find also any documentation or information about it. Anybody has such board or could supply some info? Thanks Andrea
