I use now a 32GB SanDisk Extreme with the same files on it from the 4GB SD card. Almost no difference except for the write values which are twice as high now, that's good but it could be much better ...?

I buy new ones and will Test again ... But on my Atari Falcon the same 4GB card in a 25 D-Sub v2 BlueSCSI is faster than on a IIsi. Drive C:\ is a IDE CF card and Drive G:\ is the BlueSCSI. The Atari Falcon has a LOGIC58C80 SCSI-1 Chip so 1800k - 2000k is max transferrate with SCSI ...

I can't imagine that the SD card is so bad that the write values are so low ....!

no ... ZuluSCSI has 8GB Netac SD card

I can try some other SCSI driver ...

Write is very bad ... Norton say half of the real SCSI Harddrive speed, Speedometer say the same ... I use a SanDisk 4GB mircoSD HC card

I have a Desktop v2 BlueSCSI as a replacement HDD with/in my Macintosh IIsi because of the network capability. I use a 4GB SD card with a 1.9GB HDD image on it. Set up with FWB Harddisk Toolkit. The BlueSCSI only reaches half the speed of my old 500MB Fujitsu SCSI Harddrive. I hope future...

The problem is sitting in front of the screen ... I had entered the SSID in lowercase instead of uppercase !!!

With the Accessory works it ... https://jcs.org/bluescsi ... but I like do it work out of the bluescsi.ini ...?

I don't know what the error could be. The battery voltage is present at 68HC05 on pins 13 and 27.

The same behavior also occurs with the original 3.6V battery. If the computer is connected to the mains but is switched off, everything seems to be fine. However, as soon as I switch off the mains and the computer is left for a while, the PRAM is erased. The battery is not discharged. The...

I took a closer look and it turns out that the pram stays active for a while after it is switched off but is lost overnight. I'm now going back to the original 3.6V battery...

Looking for the Q700 IIcx Power Supply schematics ...

Yes I think so ... I change the cell fro a new one (maybe a 3V cell is to low?)

I successfully repaired my Macintosh IIsi ... https://68kmla.org/bb/index.php?threads/iisi-fault.47209/ ... but I noticed that the computer has a problem with the PRAM, it always loses the settings it has made after switching it off and rarely but not. What could be the error and where should I...

... nevertheless trouble with the RAM, more precisely with the ALS245 chips. UF5 Pin18 (D8) has no contact with the Simm socket pin3 UG5 Pin13 (D21) has no contact with the SIMM socket pin20 Unfortunately the VIA from D8 was under the ALS245 and had to put a wire around the board. On D21 I was...

The new electrolytic capacitors were in the mail today. I equipped the power supply with new electrolytic capacitors and now the IIsi reacts correctly to the power button and can also be switched off again, which was no longer possible before. The chime of death is coming straight away now...

There are relatively many Nubus monochrome graphics cards with a DB9 video output. Are these always TTL outputs or are they mostly ECL outputs? TTL outputs can simply be passively connected to a VGA connection. Is there a pinout somewhere for the different DB9 video outputs?

The coil cell works well but empties quickly !
