A fresh composition of my Amiga A4000. You can clearly see that I'm not using this computer in fact the last time it has been fired up, is in the last century.
The oxidation on the outside of the FDD, clearly indicates electrolytic capacitors inside which should not be electrified.

I will need to recap this whole motherboard before I even attempt to turn it on. I'm not planning to do so though

I have an A4000T which just needs another RTG card. The Picasso 96 that I ordered for the last time broke down after 5 years.

If I really want to I can even repair the Picasso 96. The video IC is just a Cyrus logic IIRC

For me AGA is way too slow to work on such a massive machine

Which is the reason for both the A4000T which is in storage and the A4000 to be idle

Below the Amiga you can see a part of a betamax video recorder.

Ah, the timeless art of restoring an Amiga 500—because who wouldn't want to spend hours pimping a decades-old computer? 🤖🛠️ Let’s all pretend that Workbench 1.3 isn’t the pinnacle of human achievement while reminiscing about #SCSI hard drives like they're the Mona Lisa of storage. 😂👏

A BlueSCSI não é só para Macs.

I accidentally bought a 3.5" scsi floppy drive at a flea market .Only noticed it was SCSI when I looked at it at home.

SCSI discovered the laundry basket was directly beneath the hot air blowing from the heat pump. So much for cat-hair-free clothes this week.

Thanks everybody for chipping on on the SCSI question. Here is what I've gathered or derived:

The good OSes that supported the DaynaPort Ethernet devices were probably doing a read with a long timeout; the SCSI driver can definitely notify/interrupt when that read is satisfied.

The DOS ASPI layer doesn't support setting the timeout for reads. That function was available in Windows ASPI, but not DOS.

Using these under DOS is miserable; I hate the timer interrupt. ;-0

#retrocomputing #scsi

@nicolaintini While SCSI host adapters can use interrupts to signal they need attention from the OS, that AI summary doesn't answer the question.

The question is SCSI assumes that the devices are only responding to requests from the host. So if you have a packet that gets received asynchronously, there is no active read command waiting for it. In that case, how does the device get the attention of the host to ask it to do a read command?

#retrocomputing #scsi

Does anybody know how SCSI Ethernet adapters were able to signal the OS that a new packet had arrived and needed to be processed?

With storage devices and scanners the host issues a command first and the SCSI device responds. But Ethernet is different in that packets arrive asynchronously, and not in response to a host command.

Network adapters can use hardware interrupts to handle incoming packets. How did SCSI Ethernet adapters do it? Was polling the only option?

USB and SATA are nice. #SCSI was nice, too. I wonder which disk connection method had the most backward-compatibility. I know MFM and RLL weren't really long-lived, but IDE is technically still supported. You can get an IDE (PATA) to SATA adapter (in either direction) for around $8.

So technically, IDE is still the longest-lived protocol, but not connector.

Engang for længe længe siden var der noget der hed #SCSI. Hvis du ikke aner hvad det var, så tænk på det som datidens USB. Jeg var en af de kedelige der udtalte det es-se-es-i, men dem der var lidt hippe kaldte det skåssi. Nu sidder jeg lidt og overvejer om jeg burde opfinde en tidsmaskine og tage tilbage til de sene 80'ere og prøve at få folk vendt imod det mere mærkværdige skvassi.

Ting jeg tænker over, inden kaffen har gjort mig til et helt menneske.

Thanks to Alex of Rabbit Hole computing we are converting the remaining SCSI disk drives on our remote systems to #zuluscsi

SCSI, being particularly horrible this morning, is extremely pleased with himself.

Since #USB 3.0 includes #UAS, why has noone made new USB to #SCSI adaptors?

• This should be possible given stuff like the #BlueSCSI exists!

WLAN driver

Robert Smith's "DaynaPORT" driver uses the WLAN emulation available in the SD-based SCSI ‘drives’ ZuluSCSI and BlueSCSI to connect any Amiga with a SCSI host to the network. Version 1.3 fixes a problem with downloading large files, among other things.

The open source Amiga SDMAC test program, available in version 1.0, identifies the version of the Commodore SDMAC chip installed in the Amiga 3000, which accesses the WD33C93A SCSI controller - whose chip version and configuration can be read out as well.
