Hallo allemaal,
I have to correct my last email regarding the Interpod; it is only an IEC ->
IEEE convertor :( It is a pity that the devellopers didn't make an <->
convertor of it is IMHO all the needed hardware is already there so IMHO it is
only a matter of software.
About the Micropower. I was curious about the HW so I opened it. First suprise:
it did not contain a uP I knew: a R6501Q. This is a 64 pin IC but the pins are
not inline; both sides have a ZIP-package construction:
x x x x x x x x x x x x x x x x
x x x x x x x x x x x x x x x x
----------------------------------
| R6501Q |
| R1702-12 |
| 8349 |
----------------------------------
x x x x x x x x x x x x x x x x
x x x x x x x x x x x x x x x x
I once read a very old article that Rockwell was develloping a 6502 compatible
microcontroller, the R6500/1, and maybe this the same or descendent??
Second suprise: The MP contained two drives with Shugart-connectors so I
thougt: replace one with a normal 360 KB PC-drive. And as you can gues, it
worked! The strange thing is that the board only contains regular TTL-ICs (if
I'm not wrong). This realy makes one wonder if there isn't a way to make your
own 1571 in one or another way using a PC-drive as base.
Groetjes, Ruud
