I build them to order, and I also make them available on the ArcadeShopper site. I think he has two up right now, but if they are already gone I'll have half a dozen more ready within the next week or so (the boards are actually ready, but I used the last of my 74LS04s for the first three so I'm waiting on my resupply to arrive).

If I wanted to have a flex cable interface card made, who would I talk to?

 

If I do not win Globeron's auction (or worse, he cannot ship it internationally at the price point stated), I will need one should I embark down building a PEB.  My electrician skills are abhorrent. Much better at planing material and fab requirements, than handling an iron.

I have a couple in stock here.

Hi Ksarul,

 

I appreciate the quick response.  I did check Greg's site, but it says he's out of stock.

 

Could you add me to a list for one?

 

Thank you very much

I'm more interested in a side car for a 1 MB SAMS.  I started such a project a year or so ago, more like a mini-PEB, as it was intended for 3 expansion cards.  Unfortunately, my physical capabilities keep going down hill, so not able to to complete that project.  I've also came to the conclusion, that a better project would be a 1 MB SAMS side car suitable for replacing the 32K card use for the more popular TIPI system.  Anyone else interested?

That would be ideal for someone like me.

Very interested in such a project.

Was also wanting RS232, and almost decided on the Nano-PEB at first, but ultimately decided to go TIPI.

If someone could make a board that sandwiches in-between the 32K (or future SAMS board) and TIPI to provide RS232 that would be great.

Memory board > RS232 board > TIPI

Just curious what you need rs232 for? The TIPI does most of what you would need it for

Another earlier idea was to disable the 32K of a NanoPEB, so it could then be connected to a TI Speech Synthesizer and a 1MB SAMS sidecar.

My X4th99 development requires a minimum of 256K AMS for the application, and can use all of the remainder of a 1 MB SAMS for tracked disk buffering for hard disk drives MFM, IDE, SCSI and floppy diskettes!

 

RETRO Bill

It sounds like 64MB should be plenty then :-)

I'm about 80% through routing a PCB for a 1MB sidecar. Does one thing well and cheap: replace the 32K sidecar with 1MB. Use with TiPi then.

 

I'll be ordering the first proto from OSH Park in a week. If that goes well, final boards will take a month or two. It will be all thru-hole soldering and kittable.

 

(I do all routing manually to learn as much as possible. In fact, routing PCBs has replaced my game playing, its so fun.)

That will be a big step forward in the modernization of our expansion systems...
