Re: Poll: CPU choice

There were library parts for the DB9 connector. I had to make the Card Edge Connector 2x15 no 6th row myself.

Here they are, highlighted ;)

The front edge of the ROM port card edge connector is level with the recessed edge of the PCB. That puts the first row of connector pins 550 mils back from the PCB edge.

Re: Poll: CPU choice

I want to expand on this a little bit. Screen Shot 2019-03-19 at 3.00.38 PM.png This is a snapshot of the ROM port area. The top J2' area is the ROM port holes. The lower block is a duplicate. It has extra holes to the left, that will make a 2x20 block in the next revision. Those extra 10 pins add A...

Re: Poll: CPU choice

I noticed the PCB picture has no contacts for the ROM port. Intended? They’re there. There are rom port holes, then inside that is a second repeated row for internal use. Additionally, a small extra area to the left with a few more address likes, R/W and etc. It is a little misleading because the h...

Re: QL test points...

There's no need to register your interest. When they're ready I'll post photos of 50 ready to ship. I'll be doing the assembly and testing myself, as I have the facilities to do that here.

Sometimes idiot-proofing the machine includes protecting it from me ;)

Re: Poll: CPU choice

Sernet on the Superhermes does not work, as the Superhermes SER3 driver can use the STX/SRX Sernet split driver required for Sernet to operate. The only way to get reliable Sernet connections is using SER1 or SER2 at 9600 Baud. Baud rates over 9600 do not give reliable connections, assuming SMSQ/E ...

Re: Poll: CPU choice

For my needs, I do not require Microdrives. I usually remove them and use Disk or SD Card. It will take a QL-SD just like the originals. Expansions will work the same way, too. I use SERnet, between Q68, Q60, QPC2 at 115200 baud, which is faster than the QL Network. It will take SuperHermes. SERnet...

Re: Poll: CPU choice

Network is supported unchanged. Microdrives are a work in progress, but will be complete, and with the EC1 extension port, too. Microdrive struggles are due to the really poor way they were drawn in the schematics. For example, some components they put on mdv1 first, then mdv2. Others, they put on m...

Re: Poll: CPU choice

I am having some quandries. It does look like the 68SEC000 is the winner. People who voted for the 68008FN10 would be happy with the 68SEC000 also. The original 68008P8 was defeated 19 votes to three, so there's a definite desire for improvement there. One thing the 68SEC000 brings is huge clock pot...
