If this is like my S8000 (model 30 I think) system, then yse, 1/4" cartridges, DC300s IIRC. I believe the format is 4 track QIC11. -- I don't think they had more than one kind of cart controller. Have you archived the tapes, or the eproms from your system? I know it's pointless to ask, since you don't have any way to copy them, but do you have the hardware manuals for any of the cards in the system other than the CPU (which I have scanned already)

Altos 686

I had several Nabu 1200's, a Canadian built machine which was also an 8086 with 512K of RAM - 4 serial ports. Also ran Microsoft XENIX. Actually, you could run CP/M 86, QNX (a Canadian nix-alike) or Xenix - Xenix was the only one of the three which required an optional external (to the CPU) memory management unit board. I still have 1/2 of a Nabu - the machine consisted of two parts, a DISK unit which held the hard drive, WD controller and an 80-track floppy drive, and the CPU unit which sat on top. I got one of my CPU units back, however the disk unit is remaining elusive. If you are interested, you can view the CPU unit (inside and out) at my web page (see sig).

A solicitor is a particular kind of lawyer (and there's a difference between Scotland and England). But in this context, yes, it would be a solicitor who would handle wills and the like. -- Pete Peter Turnbull Network Manager University of York

I do have a thermostatically-controlled hot air gun, and I've used that for a few jobs. One was almost on-topic: I removed two DRAMs from a DIMM and put them on a special one for my 486 laptop, which didn't have enough memory to even install an old Linux distro. -- Pete Peter Turnbull Network Manager University of York

Z8000 parts question

by aek＠spies.com

> I've got one. I'm not sure if it's working, but it's complete. I also > have the install tapes (I believe). No manuals though... I just put the S8000 CPU Board manual up at www.bitsavers.org/pdf/zilog/S8000/03-3200-01_S8000cpuHw_Sep82.pdf I'll work through some others that i've scanned in the next week or two. Getting the tapes read would be a good thing. 1/4" carts?

In Memoriam: Sipke de Wal

by f.heite＠hccnet.nl

>From: "Fred N. van Kempen" >It is with great sadness that I have to announce the sudden and very >untimely death of Sipke de Wal (the Xgistor) of Noordwijk I'm very sorry to read that Sipke is no longer with us. About two years ago, he revived my interest in the old SC/MP processor. He was very kind and patient when helping me to get his SC/MP emulator running on my system. Freek Heite.

OT: Surface mount

by jpl15＠panix.com

I used to be quite disdainful / semi-scared-of SMD tech - until I designed a project for work which needed to use it and Marvin Johnston kicked my butt into working with the stuff. In addition to all the other items - I use a fine-tipped Weller adjustable iron, and I bought a nice binocular low-power microscope to work under - my past-half-century eyes need a bit of help with the tiny parts. I also use Eagle Cad for design and layout - such a long way from the tape and cut days of Xacto knives and transfer letters. All in all, I enjoy it very much, the things I'm building are postage-stamp size, and a huge parts inventory can be kept in one small set of plastic bin drawers... Cheers John
