This short post is to document Sharp PC ROMs I’ve come across so far. I’ve used MD5 and SHA1 checksums to allow their comparison. It would be nice if you could notify me of any ROMs out there that do not match the ones documented here… In an earlier post I’ve described a simple way to dump the ROMs.
- Sharp CE-150
Memory Area A000-BFFF (8 kB)
- Sharp PC-1500
Memory Area C000-FFFF (16 kB)
- Sharp PC-1500 / Sharp PC-1500A
Serial 20011xxx (Sharp PC-1500)
Serial 31070xxx – 57012xxx (Sharp PC-1500A)
Memory Area C000-FFFF (16kB)
Feel free to contact me and provide me with ROM file I do not (yet) have in my collection. I will also try to make the ROM files available in the next weeks.
To facilitate the access to Sharp Pocket Computer schematics I’ve started to collect and mirror some of them on my web site. This should allow Sharp PC 1500/1600 enthusiasts to update, modify, and especially to repair their hardware.
The Sharp PC 1500/1600 series are obsolete hardware. Their schematics are already freely available on the internet and therefore considered to be in the public domain. Please inform me if you own a copyright on some of this material and do not want it to be available on my web site.
Needing a replacement for the long ago discontinued Sharp-PC connector JAE PICL-60P-LT, I dug through a lot of datasheets and finally found a pin-compatible one:
Hirose HIF6A-60PA-1.27DS – Datasheet
Hirose HIF6A-60PA-1.27DS – Digi-Key Link
The connector fits good enough for my purposes. If necessary removing a bit of the plastic case left and right of the pins improves the connectivity as the replacement connector is a bit broader.
There is also a version with mounting holes (HIF6B-60PA-1.27DSL) which I will also try to get my hands on (currently not in stock).
My original solution was to use a 2×30 1.27×2.54 pin header as shown in this post, but the narrow space between the pins led to serious constraints in designing a new interface board (more about that when it’s ready).
Just wanted to say “Thank you” to Eric from www.pc-1500.info for supporting my efforts to create a new USB interface by sending me a TRS-80 PC-2. As a gift!
Not only that, he also sent me a CE-158 serial interface manual (here shown below my interface). Really thanks a lot! 🙂 And Merry Christmas!
