JMB363 2 Port PCI-E SATA II 2.0 RAID & 1 IDE 3.5″ to PCI Express Adapter Converter Card Expresscard (WHL #67)

Time-incorrect retro computing time! We’ve had a lot of computer-related stuff recently, but this one is an elegant mix of old, niche and Wan Hung Lo. It’s perfect.

First of all, what is it? It’s a PCI Express 1.0 x1 card with (according to Wikipedia) the only native PCIe to PATA and SATA interface chip there is, a JMicron JMB363. The “confidential” three-page datasheet floats around on the interwebs if you want to take a look. PCIe 1.0, AHCI and IDE compatible, HotPlug, NCQ, UDMA6 = ATA133 (1 port, so 2 devices), SATA2 (3 Gb/s and 2 ports, so 2 devices as well), RAID 0/1/0+1/JBOD functionality. […]


Construction fails in networking gear (#R9)

Ah well, I’m too lazy to craft another post dealing with things currently in development – let’s rant instead.

A few weeks ago I bought this huge lot of “failed” networking electronics that finally led to having an 8-port PoE switch at home, which is a nice addition – the MikroTik wAP ac finally runs on PoE as intended, the four ports (2x1G, 2x100M) of the Fritz Box router are no longer overcrowded, I did have a good time repairing two of those switches easily and I didn’t even spend a penny on all that thanks to a few sellable items (plus brownie points for donating quite a few more).
