SOL-20 Personality module 4 x MM5204

[Hugo Holden]

I have noticed that in the SOL systems manual, at least the copies I have seen, they provide the schematic and pcb layout images for the personality module which uses two other EPROMS, but not for the version my SOL has, which uses four of the MM5204 types.

Does anyone know if Processor Technology published the schematic and layout details of the version with the four MM5204 IC's, or perhaps it was only in some versions of the SOL systems manual that I have not seen ?

Thanks Bob.

Do you know if a pcb overly/track diagram was produced for the module ?

Also, where did you find the diagram, was it in a version of the Sol Systems manual or elsewhere ?

Hi Hugo

That was all I could find. I had it in my old Sol System manual but I don't recall if I ever had one - I gave my extra PMs to Bill Sudbrink, so if I had one, he has it now.

Hugo,

Have a look at my Sol-PC preliminary documentation. It's not complete but it's something. Here: http://vintagecomputer.ca/files/Proc...umentation.pdf

That is really great, Thanks!

Thanks Bob (Saver of lost Sols, I like that)

You are welcome, Hugo. I am now down to just a Sol-itary Sol (and soon a N* Horizon) - my first two original micro's.

PT used whatever was the cheapest EPROMs they could get. They had a 2708 version of the personality module which could have one actual ROM chip with a jumper change or the two 2708. I have one of each in addition to the MM5204 version. I’m also a saver of lost Sols.

The Sols are worth saving that is for sure.

I built a Martin Eberhard ME5204 programmer and I've acquired some MM5204 IC's. I am going to build an exact replica of the module in my Sol. I will post it when it is done.

(Mr. Eberhard did a really terrific & professional job on that programmer, the hardware side of things, the firmware too and the supporting documentation, it is really very impressive and I count myself very lucky to have one)
