ISO: SGI VW320 parts

by dgy＠DakotaCom.Net

Hi, I've inherited a VW320 but it is missing the drive cage. If I can get it running, I'd also be looking for some extra memory for it (wacky 40 bit? modules). I *think* I can replace the single CPU with a pair of off-the-shelf "matched" processors? Or, is this box not worth the time to get it running? Thanks! --don

Zemu

by henk.gooijen＠oce.com

Hi Zane, here is the updated zipped RL02 disk container. It has Zemu 1.10 just released by Johnny. I changed the hex fields into octal fields ... You might first try the earlier sent zip, and then this new one, to see a possible difference. If you want a zip file with the original Zemu 1.10 release from Johnny (without my hex->octal adjustment) just ask, and I'll zip it for you. thanks, - Henk. > Rats, I was afraid that PUTR was still the only way to do > this.

9 track drive and tapes on eBay UK

by andyh＠andyh-rayleigh.freeserve.co.uk

see lot 8803325888 Price (?50) looks a little on the high side but does include 26 tapes SCSI interface - almost certainly really HP tho' described as "SUN". I have bought from company before - they seemed reasonable. This (very heavy!) drive will almost certainly need manoeuvering down a flight of stairs. Parking is tight but should be possible. Andy

I'm still in touch with Dave Nelson, who is current co-chair of the IETF RADIUS Extentions Working Group. Dave worked on DECservers while in LKG. Looks like they are using the RoamAbout(r) name for their wireless stuff. Dave.

ISO: SGI VW320 parts

by ken＠seefried.com

I'm totally unfamiliar with the VW320 (which means this is undoubtedly useless advice), but at least some of the SGI Visual Workstations were secretly Tyan Thunder 2500 (aka S1867) based, and could be flashed to a far more forgiving Tyan BIOS. Perhaps there's a similar sheep in wolves clothing here?

8080 Assembler-Text Editor (ATE)

by ljw-cctech＠ljw.me.uk

I've got a hex dump here of an Assembler/Text Editor for the 8080, called (IIRC) ATE. It's what I used on my first computer (8080 S100 8k + KC tape). It's about 4k, so I had 4k for source + object, or it could work as a 2-pass assembler reading the source off tape. Does anyone know about this? Is it of interest to anyone? I could either type it in, or scan the listing for someone else :-) The code would need patching for console & tape I/O, and I don't have any documentation on how to do this, or even how to use it, but it can't be too difficult. Forgive me, it's been almost 30 years! LJW I've been quiet lately, see http://www.ljw.me.uk/porsche for an idea why :-( -- Lawrence Wilkinson lawrence at ljw.me.uk The IBM 360/30 page http://www.ljw.me.uk/ibm360

11/45 interrupts

I'm getting a little time to go back and work on my 11/45 project... Tony wrote... >> So, I would propose the following tests : >> >> 1) Make sure you can read/write all bits from external memort.
