Example of replacing exhausted Electrolytic Capacitors.

My advice is always to replace all capacitors although at first view does not seem exhausted with acid leakage.

Forth, the Language.

Forth is a different language. It’s aged and a little weird.
What’s cool about it? It’s a very low-level and minimal language without any automatic memory management. At the same time, it easily scales to become a very high-level and domain-specific language, much like Lisp. Compared to C64 Basic, Forth is more attractive in almost every way.

It is a lot more fast, memory effective and powerful. Compared to C, specifically cc65, the story is a little different. It’s hard to make a fair comparison. Theoretically Forth code can be very memory efficient, and it’s possible to make Forth code that is leaner than C code. But it is also true that cc65 code is generally much faster than Forth code.

Someone has to repair these computers! ;-D

In the photo you can see: Commodore 64(C) motherboard, Commodore Amiga 500 motherboard, Commodore Amiga 600, Sinclair QL, Commodore 128 motherboard and some Amiga keyboard.

HermIRES it’s a cross-platform hires bitmap (Art Studio 1 format) editor for the Commodore 64.

The format has some restrictions, here are the rules:

• The maximal resolution of the picture is 320×200
• Only 16 fix C64 colours can be used (no gradient either)
• In a 8×8 pixel-block only 2 colours can used to be displayable by C64 (this is detected in HermIRES, but .hbm files can be saved with clashes too.)
• On a real C64 the PAL will blur the screen-content a bit, should check on CRT, or at least VICE emulator’s CRT simulation.

Changelog:

• AFLI caption can be fully disabled (AFLIexe-patch included along with bin2array.exe)

Download:

• HermIRES v1.29 (Windows/Linux) (1228)

I have received a Lemon II computer (Apple ][+ / Europlus Clone) in a good cosmetic condition but with a serious problem at the keyboard, here below defects and repairs that has been made.

Cleaning comparison (before / after):

Gallery of the repair:

Defects:

• First problem: When a keyboard key is pressed is always displayed the same character, in this case the character “O”
• Second problem (which i have only noticed after solving the first one): The keyboard works correctly, all characters are displayed in the correct way, but sometimes the character displayed does not match with the key pressed. Example: when pressing many times the letter “I”, after a while is displayed the character “Y” and after a while it show the right character “I”.

Components Replaced:

• 2 x 74LS191 (UP/DOWN Counters)
• 1 x SMC KR2376-ST (Keyboard Encoder)

I have to thank my friend Luca that called me to inform me that there was still a piece of the SMC KR2376-ST available in the store.

Olivetti S.p.A. is an Italian manufacturer of computers, tablets, smartphones, printers and other business products such as calculators and fax machines. Headquartered in Ivrea, province of Turin, the company has been part of the Telecom Italia Group since 2003.

The primacy of the first PC can be assigned to Olivetti thanks to Programma 101, which was produced in 1964 and had a big success in the U.S. market.

Olivetti’s first modern personal computer, the Olivetti M20, featuring a Zilog Z8000 CPU, was released in 1982. In 1983 Olivetti introduced the M24 and in 1984 the M21 (the first and last of transportable of Olivetti), a clone of the IBM PC using DOS and the Intel 8086 processor (at 8 MHz) instead of the Intel 8088 used by IBM (at 4.77 MHz).

The M24 was sold in North America as the AT&T 6300. Olivetti also manufactured the AT&T 6300 Plus, which could run both DOS and Unix.
