Re: WTB: RX02 Floppy Disks

Hi All, All my 8" SSDD /SSSDdisks are non formatted, which was the reason for my initial troubles. Nevertheless, my IBM System /23 (Type 5324) can format disks in three different formats: _1. IBM System /23 Format_ 512 Bytes per Sector Possible Disk: SSSD, SSDD, DSDD _2. Standard Format_ 128

Wow, that's mighty impressive. I knew about your FPGA 360/65 project but had never seen your website before. I must visit next time I'm close to the Netherlands! Marc On Jul 29, 2017, at 11:17 PM, Camiel Vanderhoeven via cctech wrote: My Convex C220 arrived about a

Re: Vintage HP 1000 Floating point processor ( EBAY )

BTW I know the seller well, he is local to me and I have had no issues dealing with him. These come from a large stash that came from a former HP 1000 maintenance shop (Advent I think was their name, or something like that). That's one of the few units I didn't take ;-) Marc On Aug 3, 2017, at

Free for shipping: Cabletron MR-9000C Ethernet (thin-net) repeater

All, I will not get around to using this, so it’s free for shipping (or for pickup). Cabletron MR-9000C ethernet repeater. One AUI port designed to connect to a thick-net bacbone via an adaptor which I don’t have. 8 thin-net coax ports, LED indicators for each. Also
